- "We are Forerunners, guardians of all that exists. The roots of the galaxy have grown deep under our careful tending. Where there is life, the wisdom of our countless generations has saturated the soil. Our strength is a luminous sun towards which all intelligence blossoms, and the impervious shelter beneath which it has prospered."
- —The Ur-Didact, giving a speech on the purpose of the Mantle.
The Forerunners (Latin Primoris prognatus, meaning "Firstborn") were an ancient species of technologically advanced beings whose empire—known as the ecumene—encompassed three million fertile worlds in the Milky Way Galaxy. The Forerunners reigned for millennia as the ascendant civilization in the galaxy until the activation of the Halo Array, their Pyrrhic solution to halt the Flood, in 97,445 BCE. Although they themselves are essentially extinct, evidence of their existence remained, spread across the galaxy in the form of numerous creations, installations and artifacts.
The Forerunners took upon themselves the role of caretakers of the galaxy, and believed that this "Mantle" had been passed down to them by the Precursors, an even more powerful race that preceded the Forerunner civilization. "Forerunner" is a literal translation of the species' name for themselves; they identified themselves as such because they believed that they held an impermanent place in the universe's Living Time, though, in time, they too would be succeeded by other, superior races. Before their disappearance from the galaxy, the Forerunners would name humanity their successors, identifying them with the title "Reclaimer".
In modern history, the alien hegemony known as the Covenant revered the Forerunners as gods, deriving much of their own technology from Forerunner artifacts found throughout the galaxy, and held that any who defaced these relics were heretics.

|“||One hundred thousand years ago, the galaxy was populated by a great variety of beings. But one species—eons beyond all the others in both technology and knowledge—achieved dominance. They ruled in peace but met opposition with quick and brutal effectiveness. They were the Forerunners—the keepers of the Mantle, the next stage of life in the Universe's Living Time. And then they vanished.||”|
The Forerunners were created by the Precursors, a powerful race responsible for seeding the Milky Way Galaxy with life and creating many other species, fifteen million years ago. The Forerunners were seeded on the planet Ghibalb in the Orion complex. The world served as the hub of the Forerunners' fledgling interstellar civilization, comprised of twelve systems within the nebular complex, until it was rendered uninhabitable by an astroengineering disaster. The Forerunners had attempted to manipulate several stars in their region of space, but accidentally caused a series of supernovae that resulted in their planet being burned to a cinder by radiation. This event nearly caused the Forerunners' extinction.
As their interstellar civilization developed, the Forerunners came to believe they would be judged worthy to be the inheritors of the Precursors' Mantle of guardianship of all life. However, over ten million years ago, the Precursors made a decision to pass down the Mantle to humans instead. Provoked either by this revelation alone, or the Precursors' alleged decision to eradicate the Forerunners as a "problematic" species, the Forerunners responded by overthrowing their creators, exterminating most of them in retaliation.
The Forerunners, led by the then-dominant rate of Warriors, began their thorough campaign of extermination in the Milky Way galaxy and later chased the last Precursors down to the satellite galaxy of Path Kethona. There, they would finish their work, eradicating all but a few Precursors who managed to elude them. However, some Forerunners began to question the ethics of the genocide and refused to take part; many were summarily executed, while others were exiled on a barren planet in Path Kethona without any advanced technology. This population would survive for millions of years, preserving the knowledge of their origins in a biological reservoir of ancestral memory. However, they would remain as the last survivors of the fleet that traveled to Path Kethona, as those who had carried out the genocide until the end never returned to the Milky Way.
Records of this war were gradually lost to time over millions of years, and Forerunner civilization as of the Forerunner-Flood war believed that the Precursors had simply disappeared after fulfilling their ultimate goal: creating the Forerunners to be their successors as holders of the Mantle. For several millions of years after the annihilation of the Precursors, the truth was purposefully suppressed by those in power; there were some who attempted to uncover the true relationship between the Forerunners and the Precursors, but they were discreetly silenced, mainly by Warriors and Builders.
Over the course of their history, the Forerunners fought each other in a number of civil wars, one of which took place over half a million years before their war against the Flood. To safeguard the Orion complex—the center of the ecumene's governance—during these conflicts, the Forerunners constructed the Maginot Line, an immense array of defensive installations spread out in a sphere which completely surrounded the Orion complex. This defense was meant to repel any possible enemy incursion, but it eventually proved vulnerable against an unconventional attack. During the civil wars, the Builder rate first rose to supremacy and initiated a cultural purge of the other rates, such as Warriors and Miners, which involved the suppression of their ancient rituals.
The Forerunner civilization had cemented its place as the preeminent civilization in the galaxy by roughly 150,000 BCE, around the same time humanity first began moving its first interstellar civilization away from their homeworld, supposedly to escape early Forerunner control. The Capital, the center of the Forerunner ecumene and the seat of the Ecumene Council, was constructed around 122,445 BCE. At some point in their history, the Forerunners fought a series of battles known as the Kradal conflicts in the galactic center.
War with humanity
- Main article: Human-Forerunner war
Around 107,445 BCE, the Forerunners went to war with humanity's interstellar empire, in response to a perceived invasion of worlds where the Forerunners had relocated other species. This invasion was thought to be caused by both human resentment at Forerunner expansionism during the previous fifty years and by the rapid growth of human populations. After the war, a small number of Forerunners discovered the true cause of the invasion: a desperate human migration away from an extragalactic parasite known as the Flood. Desperate for new, uninfected worlds to replace the ones lost to the Flood, humanity invaded the worlds of other civilizations, bringing them into direct conflict with the Forerunners, who saw themselves as protectors of the Mantle.
The Forerunners perceived humanity's actions to be a threat to the principles of the Mantle, and therefore waged a decisive war against humans, subjugating every human-controlled world and wiping them clean of all traces of human civilization. As punishment, humanity was stripped of its empire and technology and was exiled to its homeworld, Erde-Tyrene. There, humanity was devolved, splintered among its collective species and forced to begin anew. The Flood, meanwhile, had been pushed beyond the edge of the galaxy by humanity's military efforts and was not seen again for nearly nine millennia.
Following the events of the war with humanity, a select group of Councilors and other elite Forerunners turned their attention to the possibility that the Flood would return. The Didact advocated a policy of watchfulness and military readiness, and proposed the construction of a series of shield worlds to provide quick military support should the Flood reappear. However, this plan was overruled by the council in favor of one put forward by a faction of Forerunner Builders led by Master Builder Faber-of-Will-and-Might, who proposed the construction of an array of galaxy-sterilizing superweapons as the ultimate defense against such a threat. These proposed weapons would be designed to starve the Flood to death by killing all sentient life in the galaxy with enough biomass to sustain them.
The Council's acceptance of this plan caused the Librarian, a prominent Forerunner Lifeworker and the wife of the Didact, to speak out in condemnation of the Builders' proposal of mass genocide, and as a result, she and other Lifeworkers were permitted to work on the project as well, integrating their own measures for preserving the galaxy's life into the plan. The plan, the Conservation Measure, resulted in the Lifeworkers gaining biological preserves on the Builders' installations, including two Arks and a network of massive ring-shaped superweapons known collectively as the Halo Array. Meanwhile, the Didact and the other Prometheans who had supported his cause were removed from the council and executed or exiled. The entire Warrior-Servant rate was marginalized over the next thousand years, with their fleets and armies disbanded or merged into Builder Security, leaving the Forerunners ill-prepared when the Flood re-emerged.
- Main article: Forerunner-Flood war
Roughly nine thousand years after their war with the humans, a Forerunner survey team on the planet Seaward came into contact with the Flood. After this first contact, the Forerunners immediately recognized the great danger that the Flood posed to the entire galaxy and attempted to contain them. Even though they knew the power of the Flood, the principles of the Mantle forbade them from destroying it. As such, the attempt to contain the Flood was a failure, as they tried methods more suited to disease control instead of all-out warfare, trying to contain and quarantine the Flood rather than attack and destroy it outright. They did not start war until it was far too late.
When the Forerunners were unable to contain the Flood outbreak, the galaxy entered a state of war. The Forerunners desperately studied the Flood, looking for any exploitable weakness. As the Forerunners soon realized that conventional naval tactics were ineffective against the parasite's onslaught, they developed new weapons and tactics to combat the Flood. The Sentinels were deployed as a means of maintaining the Flood through surgical, localized tactics. Eventually, the Forerunner fleet began to enact premature stellar collapse within compromised planetary systems, causing supernovae to engulf entire worlds. However, these tactics proved only to slow, but never stop the expansion of the Flood. Even at this late hour, the Forerunners were reluctant to use the Halo Array, believing that they should continue to embrace the Mantle and to protect life rather than to destroy it. This led to great stretches of anguished debate and even civil war.
Firing of the Halo Array
- Main article: Great Purification
- "After exhausting every other strategic option, my creators activated the rings. They and all additional sentient life within three radii of the galactic center, died, as planned."
- —343 Guilty Spark on the fate of the Forerunners.
After nearly three centuries of war, what had been a relative stalemate quickly began to turn in the Flood's favor. The Gravemind managed to convince Mendicant Bias, the AI in charge of Forerunner defense, to unite with the Flood and turn its military assets against its creators. With the Flood growing at an exponential rate, entire themas of the ecumene were overrun; the Flood-infested regions, known as Burns, soon covered two-thirds of Forerunner space. The Forerunners eventually resorted to the Maginot Line, leaving all systems beyond the Orion complex to fend for themselves. Meanwhile, the Flood and the Graveminds developed into more capable and powerful forms, enabling them to tap into Precursor neural physics and control Precursor artifacts scattered across the galaxy. The Forerunners possessed no effective defense against these constructs and the Flood won most naval engagements as a result.
After the Capital system was overwhelmed, the surviving leaders and population of the ecumene were relocated on the extragalactic installation known as the greater Ark, the original Ark used to manufacture the first Halo rings. Aware that the Ark would not stay safe from the Flood for long, the Forerunner leadership realized that the only way to stop the parasite was to deprive it of all hosts by firing the Halo Array. Soon after this decision, the Flood attacked the greater Ark and destroyed it. With most of the Forerunner leadership and population dead, the few surviving Forerunners, led by the IsoDidact, journeyed to Installation 00, the lesser Ark, its location still hidden from the Flood. The IsoDidact had the Halos distributed across the galaxy and activated the rings, killing all sentient life of sufficient biomass in the Milky Way, including any surviving Forerunners within the range of the Halo effect. However, the Forerunner Lifeworkers had managed to save some of the galaxy's species by transporting them to the Ark during the Conservation Measure. All neural structures within the Halos' range were destroyed; these included all Precursor artifacts, including the Domain, which the Forerunners had come to regard as the foundation of their culture.
- Riser: "We will do what we can with what we are given. But what of you? Where will the Forerunners live?"
- IsoDidact: "I do not know, not yet. All I know for certain is that we cannot return to these places. We have already meddled too much in the affairs of others."
- —Riser and the IsoDidact as they bid farewell on a repopulated Earth.
A number of Forerunners survived the firing of the Halo Array. Some managed to take refuge on Installation 00, safely out of the Array's range, while the Halo effect swept over the galaxy; most notably, this included the Lifeworkers assigned to installation and the IsoDidact. Based on limited information prior to the firing of the Halos, most of the other rates were believed to have perished on the greater Ark, though a number of Warrior-Servants, Builders, and Engineers were shown to be present later on, indicating that more Forerunners survived to take shelter on the lesser Ark than previously predicted.
After the remaining Forerunners had made sure that the Halos had done their work and the Flood had been eliminated, the species that were preserved on the Ark were returned to their home planets, a process lasting for over a century. This was done by the remaining Forerunners under the leadership of the new Lifeshaper, Chant-to-Green, who received the title from the Librarian before the latter stranded herself on Earth at the endgame of the Flood war.
Following the reseeding process, a group of surviving Forerunners led by the IsoDidact traveled to Maethrillian, the ecumene's former capital, in an effort to repair the Domain. Within the capital, they were confronted by a Precursor construct known as Abaddon, who had been housed in the megastructure for millennia and now intended to bring the Forerunners to trial for their crimes. However, the Forerunners were successful in restoring the Domain, undoing some of the damage the Halos had caused.
The remaining Forerunners subsequently exiled themselves, as, according to the IsoDidact, they were done meddling in the affairs of others. This exile has also been referred to as a "Great Journey" by the IsoDidact, who wished to bear the record of the Forerunner civilization's failures and their ultimate sacrifice for future generations. The Forerunners left the Milky Way, journeying to another galaxy where they spread their numbers thin, with the plan of allowing their species to die out in time. At least the IsoDidact and Chant-to-Green gave up advanced technology in favor of a simple, primitive lifestyle.
Apart from the Forerunners sheltered on the Ark, the Ur-Didact also survived, having been imprisoned in a Cryptum in the shield world Requiem. 343 Guilty Spark believed that the Librarian had also survived; however, this information is of questionable veracity, given first-hand accounts of the Librarian spending her last moments stranded on Earth when the Halos were fired, and the surviving Forerunners never making contact with her before their exile. While the survival of the Librarian herself is dubious at best, she did upload a personality impression of herself on Requiem to guide humans if they later stumbled on the installation.

- —Avu Med 'Telcam
After their disappearance, the Forerunners left behind a great deal of artifacts, many of the more significant ones overseen by their dedicated monitors which would react to outside visitors in accordance with their programmed instructions. The mystery surrounding the Forerunners and their technology would later become a source of worship, legend, advanced technology, or combination thereof for the various future civilizations which eventually stumbled upon some of the many Forerunner artifacts across the galaxy.
The first known species to make use of reverse-engineered Forerunner technology were the Sangheili and San'Shyuum, having evolved on worlds rich in Forerunner artifacts. Regarding these artifacts and their creators with religious reverence, many wars broke out over whether the relics should be left in peace or used to advance their own technology. Those who believed the latter came together to form the hegemony known as the Covenant, who together created a complex religion based around venerating the Forerunners as gods. Due to misinterpreting the ancients' records, the Covenant believed that the Forerunners disappeared from the galaxy after the Halo Array elevated their species to a state of trans-sentient godhood. As such, they appropriated many Forerunner technologies and artifacts, with the use of Luminaries that allowed them to track Forerunner-made objects all across the galaxy. The most holy of these artifacts, the "Sacred Rings" or Halo installations, were constantly searched for 1700 years, since the Covenant believed themselves to be the chosen inheritors of the Forerunners' legacy, and by locating and activating the Halo Array, they believed that they too could follow the Forerunners into godhood. This was referred to as the "Great Journey" by the Covenant races. This mimicry of the Forerunners' remnants caused the Covenant to rise to a high technological tier very quickly, but additionally stunted their innovation of said technology and kept them from uncovering its true potentials.
As for humanity, they had been chosen by the Forerunners to carry the title of "Reclaimer" and eventually take over the Mantle. The Librarian had imparted humanity with a species-wide geas; these genetic instructions include an innate familiarity with Forerunner technology. However, humans themselves were unaware of this and came into contact with Forerunner artifacts relatively late in their history, after they had colonized many planets. In 2491, a collective of human artificial intelligences uncovered the presence of Forerunner relics on Onyx and kept them hidden in the meantime for fear that humanity was not yet ready to use such advanced technology. As such, archaeological excavations did not uncover them until 2511, and the UNSC's Office of Naval Intelligence responded by hiding the planet's location and securing the area. However, little progress was made in translating any of the relics. Other relics were discovered on Reach, Earth, and many other colonies. A Reach titanium mine had been shut down when they breached a Forerunner complex, and SWORD and CASTLE Base were built to guard relics' locations. The Portal at Voi was buried under New Mombasa and undiscovered until much later, prompting ONI to construct a major facility to study and cover up the structure from the general population. Mixed reactions came from scientists who studied the artifacts, some fascinated by their potential, others fearful for the possibility of a two-front war.
- "Mankind is outmatched. When Reach falls - and it will fall - our annihilation is all but certain. Unless...we can glean from this artifact a defense against the Covenant. A game-changer. On the level of the conical bullet in the nineteenth century, or faster-than-light travel in the twenty-third."
- —Dr. Catherine Halsey, after decrypting the Forerunner artifact under SWORD Base.
Forerunner artifacts became instrumental to beginning and ending the Human-Covenant War. First contact was made when humanity's Reclaimer status was discovered by the Covenant, who did not understand that they were being labeled as Forerunner objects. The Hierarchs of the Covenant soon learned humanity's status as apparently living descendants of their supposed gods, and found it potentially destructive to their religion. Thus they decided to hide this information from the general population and ordered that humanity be eradicated, a goal in which they nearly succeeded. Battles were fought often with relics at the center of the conflict, sometimes risking giving the Covenant victory early, other times hindering them and turning in favor of humans due to the Covenant's reluctance to damage Forerunner treasures. Many relics were destroyed by humans often as traps for Covenant or to keep them from falling into enemy hands.
The most important of Forerunner artifacts to be involved was the Halo Array, the first ring of which was discovered on the heels of the destructive Fall of Reach. The resulting Battle of Installation 04 revealed to humanity the existence of the Forerunners and their sacred place in the Covenant's religion, as well as the rings' true purpose as weapons of mass destruction. The activation of the Halos led to the awakening of other Forerunner relics, such as the Sentinels of Onyx, or the Ark that controlled the Halo Array. Humanity's utilization of Forerunner tech was thus regarded as a "game-changer" to turn battles into their favor and also changed the goal of the war, now to keep the Covenant from reactivating the Array in their misguided pursuit of apotheosis. As the conflict drew to a close, the Covenant had been plunged into civil war as some discovered the Great Journey was false and thus allied with humanity. The final battle of the war was fought aboard the Forerunners' Ark, and the UNSC and Covenant separatist forces together secured the Halo Array, destroying the Ark shortly afterward. In the post-war years humanity was beginning to reclaim its appointed place, gaining many technological leaps as a result of acquiring and reverse-engineering Forerunner technology with the assistance of a number of Huragok they had managed to procure.
- "Time was your ally, human, but now it has abandoned you. The Forerunners... have returned."
- —The Ur-Didact to John-117, after being awakened in the interior of Requiem.
The years following the end of the Human-Covenant War saw the revival of a Forerunner presence in the galaxy, with the reawakening of the Ur-Didact, once the supreme commander of the Forerunner Warriors-Servants. A zealous Forerunner supremacist with a renegade hatred of humans, the Ur-Didact sought to use a machine known as the Composer to convert all of humanity into subservient war machines near the end of the Forerunners' war with the Flood. To prevent this, the Librarian imprisoned the Didact in a Cryptum on the shield world Requiem, where he remained for the next 100,000 years.
In July 2557, the Ur-Didact and his mechanized Promethean forces were accidentally awakened by Spartan John-117 who had stumbled upon Requiem. His views unchanged by his long exile, the Didact disregarded humanity's Reclaimer status and maintained his belief that only the Forerunners were worthy of the Mantle. The Didact and his Prometheans, allied with a new Covenant faction, went to war against humanity, aiming to prevent them from claiming the Mantle to themselves. Attempting to use the Composer to neutralize humanity, the Didact attacked Earth. However, the Master Chief and his AI Cortana stopped and defeated him, destroying the Composer and the Didact's ship. They were aided in this by the Librarian, who had left an imprint of her memories behind on Requiem. The Librarian's essence augmented the Master Chief's genetic code in order to allow him to face the Didact, giving him, along with other things, an immunity to the Composer that saved his life. However, the Promethean-Covenant alliance was not defeated by this setback and the conflict was still in progress in early 2558 when the UNSC Infinity returned to Requiem. After a lengthy campaign, Requiem was destroyed by the Covenant leader Jul 'Mdama, along with all Promethean constructs present on the shield world.
The Forerunners were a bipedal species resembling humans in overall shape, though they were larger in stature. Over the course of their lives, Forerunners underwent a number of artificially-induced mutations, modifying their bodies to better suit the field of work of their rate. More specific aspects of their appearance varied with lineage, age and even personal tastes. They relied heavily on personal body-assist armor which, in addition to protecting the wearer from harm, augmented their physiology and mental faculties. Among many other advantages, it made their lifespans virtually indefinite by providing constant life support and medical care.[note 1]
Before their first mutation, as Manipulars, Forerunners were tall and slender, and possessed patches of fine, purple-pink or white fur on the top of their heads, along their nape and shoulder area, as well as the backs of their hands. Their facial features were similar to those of humanity, and they were capable of making analogous expressions, but this changed as they mutated to their higher forms, which characteristically had stiffer facial muscles and a more limited ability to convey emotions. There was also a cultural stigma associated with expressing emotions; while even certain higher forms were capable of producing some semblance of a smile or laughter, for example, such uncontrolled display of emotions was regarded as barbaric. Unlike humans, Forerunners lacked pronounced noses or ears, having two slitted nostrils and a set of bulbous protrusions instead. Their skulls otherwise bore a very strong resemblance to those of humans, with subtle differences. The Forerunners also had a genetic code that was remarkably similar to humans, though they were not known to be genetically related.
The Forerunners exhibited sexual dimorphism largely mirroring that of humans, with the females being more slender and somewhat smaller in stature than the males. The height of higher-form males ranged from around three to four meters; for example, the Ur-Didact was three and a half meters tall, while Bornstellar's father, a high-ranking Builder, was around four meters. Bornstellar's mother, a female Builder of the same social standing, was just over two meters in height, while the Librarian, head of the Lifeworker rate, was nearly three meters tall. Males of higher forms also bore less resemblance to humans, while the females appear to have been more human-like in appearance. A large portion of this dimorphism was artificially induced with their mutations and determined by rate.
Their skin color ranged greatly, including gray, black, blue, pink, or a mixture thereof. The number of fingers Forerunners possessed varied according to their rate and form; the most common number of fingers per hand appears to have been six, with two opposable thumbs, although some Lifeworkers could have as many as seven fingers per hand. Meanwhile, the Librarian had only five fingers in each hand, although this was a deviation from the norm.
Thanks to their advanced life-support and medical technology, Forerunners could maintain a youthful appearance for thousands of years should they so choose. Even though Forerunner armor was capable of healing most injuries which would otherwise be certainly lethal, including fatal doses of radiation, on rare occasions Forerunner individuals may choose to decline basic treatment; the ancient Warrior-Servant known as Bitterness-of-the-Vanquished, for example, chose to remain blind and instead relied on her armor to provide sensory input for her.
While the Forerunners had a biological need to sleep, this necessity was eliminated by the use of personal armor which allowed them a constant continuity of consciousness without having to sleep; only on rare cases, they would experience diagnostic waking dreams. As such, Forerunners slept very rarely, mostly doing so by choice in instances such as long stretches of space travel, which themselves were rare due to their exceedingly fast slipspace technology.
Forerunners possessed highly advanced mental capabilities, far beyond those of a human in the case of their higher forms. These abilities were further augmented by their use of personal armor, which integrated with the wearer neurally and stored sensory information and memories, even consistently backing up the wearer's consciousness. The armor also allowed Forerunners direct information transfer to one another, which could also be employed in the form of "silent conversation". Higher-form Forerunners had the ability to process enormous amounts of information simultaneously; for example, Warrior-Servant commanders could simultaneously process the sensory input of thousands of their subordinates while coordinating large-scale battles and themselves experiencing reality in multiple separate frames of reference with variable streams of time. The use of an ancilla enabled Forerunners to recall any past event with exact accuracy, and even without armor or a personal ancilla they could remember enormous amounts of precise information; for example, the Didact was able to recite a verbal control code consisting of hundreds of completely random words and numbers after thousands of years.
- Main article: Forerunner mutation
When a Manipular was ready to work within a particular rate, they would undergo an artificially-induced transformation into a more advanced form, which differed depending on the Manipular's chosen caste. Referred to as a "mutation", the transition typically occurred over a long period of time. A typical Forerunner would undergo several mutations over the course of a lifetime, though this was not always the case. Mutations altered Forerunners' abilities and physical shape to suit their class; Warrior-Servants, for example, underwent mutations that made them stronger and more robust. After their first mutation, Forerunners also gained the ability to access the Domain, a realm of information where the entire collated knowledge of the Forerunner civilization was contained.
In emergency circumstances, an operation known as a "brevet mutation" could be performed on a Manipular. This was a mutation that occurred over a much briefer period of time, and was often painful. Rarely, a brevet mutation could fail and result in deformities; there were rumors that Forerunners whose mutations had failed were sequestered in special enclaves, hidden from the general population. The Ur-Didact performed a brevet mutation on Bornstellar Makes Eternal Lasting to give him access to the Domain.
Society and culture
The Forerunner civilization was based around the Mantle of Responsibility, a belief that it was their role to protect all life in the galaxy; it was generally believed that the Forerunners had gained the Mantle as a birthright from the Precursors after they vanished. As a result of their perceived status as universal guardians, the Forerunners largely secluded themselves above other species. They monitored the evolution of other sentient species throughout the galaxy, intervening in ways that ensured their civilizations would follow paths of peace, free of conflict, but also so that they would not challenge Forerunner dominance. To maintain their position, the Forerunners committed acts such as relocating other species from their homeworlds in order to expand their own empire or gain control of new resources. They also enforced the Mantle by hindering the development of other species, even reducing opposing species to small populations of specimens, as they did with early humanity. Those species who submitted to Forerunner rule lived within the ecumene as subject species, allied with but ultimately subservient to the Forerunners; some of these species helped eliminate pockets of human resistance after the human-Forerunner wars.
The Forerunners themselves were a race almost entirely without conflict; although political disputes were not uncommon, violence or war between Forerunners was almost unheard of, the last Forerunner civil wars having been fought half a million years before their civilization's end. As such, the Warrior-Servants, who conducted most of the Forerunners' military operations, were often looked down upon by the higher rates, as their actions were perceived to be contradictory to the Forerunners' role of preserving life. While they generally strove for peace, when provoked to a war, the Warrior-Servants would carry out the war ruthlessly and thoroughly, as they believed defiance of their rule was equal to showing contempt to the Mantle itself. One example is the human-Forerunner wars, where many humans were executed following their defeat, and all traces of human achievement was erased from the galaxy.
Forerunner culture was highly stagnant; the fundamental aspects of their society—such as their rate-based social hierarchy—remained unchanged for millions of years. The Forerunners had a rigid social structure, where one's position would be determined mainly by their rate, part of a complex system of different social classes mainly based around a particular occupation. Cultural practices and customs varied by rate and position; generally, Forerunner culture was full of formality and ritual, particularly with the Builders, the highest of the rates. Forerunners placed a great deal of value on family lineage and tradition, and one's rate and social standing were largely hereditary. When Growth-Through-Trial-of-Change, born to a Builder family, chose to become a Lifeworker instead, she was treated as an outcast by her family.
A central aspect of Forerunner culture was the Domain, a vast repository of information containing virtually all knowledge collated by the Forerunners over the eons, including impressions the deceased, leading the Forerunners to also view the Domain as a form of afterlife. Although the Domain permeated Forerunner society for countless millennia, its origin or true nature remained mysterious to the Forerunners themselves. The Domain was best understood by the monastic class of Haruspices, who dedicated their lives to the study of the Domain. While unknown to the Forerunners, the Domain was actually a neural physics-based Precursor construct, and as such was destroyed when the Halos fired, taking most of the Forerunners' recorded history and knowledge with it.
Despite their lack of need to sleep as a result of the use of personal armor, Forerunners had certain moments where each member of a household would retreat for several hours of individual meditation. These moments were typically arranged according to the local day-night cycle, and were sacrosanct in traditional Builder families. During this time, the activities on an entire planet would slow down, including traffic and even the operations of ancillas.
Forerunners did not eat meat, as the Forerunners' scripture surrounding the Mantle forbade "the eating of the flesh of unfortunates". Taking one's own life was also gravely forbidden. Despite their in many ways conservative society, nudity or sexuality were not considered taboos in Forerunner culture; for example, it was normal for both participants to be naked during the rite of mutation, without the procedure being considered explicitly sexual.
Some Forerunners rejected their advanced technology, including personal armor, and adopted a more austere and primitive lifestyle in seclusion from the rest of Forerunner society. One such community existed on Seaward, which would incidentally become the first planet in the Forerunner ecumene to be overrun by the Flood.
Government and politics
The Forerunners' primary governing body was known as the Ecumene Council. Based in the capital, it was led by the First Councilor and composed of five hundred Councilors, in addition to support by a network of ancillas known as the Council metarchy. The Councilors, who came from various rates, typically served for a thousand years and led humble lifestyles. The capital also housed the ecumene's primary judicial institution, known as the Capital Court, which could be assembled into the Supreme Mantle Court in times of great crisis.
- Main article: Rate
Forerunner society was divided into a number of different classes known as rates, each rate specializing in a particular field of work. The Builders, who designed most Forerunner technology, from ships and weapons to their various megastructures, were the highest rate and wielded the most political power. The second rate were the Miners, who obtained construction materials for the Builders' projects and were responsible for planetary and stellar engineering. Below the Miners were the Lifeworkers, who were responsible for medicine and biological research. The Juridicals were a rate whose duties encompassed legal matters within the ecumene. The Warrior-Servants served as the primary fighting force of the ecumene, while the Engineers maintained technology and machinery.
The rates, in turn, were divided into smaller units, guilds, Maniples and clans. Adolescent individuals, known as Manipulars, were not considered to be part of a rate until their mutation into first-form. During special occasions, each rate of Forerunners wore unique ceremonial headgear except for one day of Grand Star Season, when all rates would wear similar headgear.
Family and marriage
Forerunner customs involving marriage were said to be complex; they married for a variety of reasons, though it was said that the lower rates married more often for love, while there were often more complex reasons such as familial relations involved in the courtship of higher rates such as Builders. Intermarriage between rates was not unheard of; for example, the Didact, a Warrior-Servant, married the Librarian, a Lifeworker. Additionally, a certain degree of courtship between rates was considered commonplace before individuals were espoused to formal marriage. Polygamy was also an accepted practice, at least among the higher rates, as demonstrated by Master Builder Faber having many wives. At certain points in their lives, females would enter a "millennial interim", a period when they would not bear children.
Languages and scripts
Forerunners spoke a variety of languages. Some dialects were older than others, and accordingly were less widely used. Digon was an ancient language used by Prometheans, while Jagon was a slightly less old language used by Builders.
The most commonly encountered system of Forerunner glyphs seems to be based on a series of circular, complex shapes. The glyphs have been inscribed almost everywhere Forerunners were once present, from different areas of Earth, to the Halos. They were also known to put these glyphs and symbols onto their weapons, machinery and clothing, something the Covenant also copied, evident with the Forerunner symbols placed on the hilt of the energy sword and on the Sangheili combat harness. Among the most well-known glyphs are the "Mantle" and "Reclaimer" symbols, as well as the sigils of individual Forerunners. Some variations of Forerunner symbology possess a strangely attractive, even disorienting quality to humans.
In addition to the well-known symbols and glyphs, the Forerunners also utilized a more conventional writing system. The characters used in Forerunner writing have been described as resembling a series of dots, squares, bars and triangles. The Covenant writing system is derived from the original Forerunner script, although they use highly embellished variations of the simple, geometric characters used by the Forerunners.
Forerunner names had concrete meanings in their language, and commonly consisted of a combination of words expressing positive attributes in a grandiose, somewhat poetic manner. In many cases, a Forerunner's name was associated with typical terminology involved with the practices of the rate they were born into; for example, "Bornstellar-Makes-Eternal-Lasting" reflects his Builder lineage. In informal conversation, these names were typically shortened, with only a single part being used.[note 2]
Many, though not all, higher-ranked or older Forerunners were only known by a title not given at birth but rather adopted at one point in the Forerunner's life, often originating as a sobriquet given to that individual due to one of their traits; for example, the Didact, born Shadow-of-Sundered-Star, gained the name "Didact" from his students while teaching in the War College. Manipulars were identified as "Form Zero" in their full names.
When a Forerunner died (usually by accident or, on rare occasions, during war) elaborate ceremonies would be enacted before their remains were disposed of in fusion fires associated with the activities of their rates — a melting torch or planet cutter, for example.
First, the Forerunner's last memories would be extracted from their armor, which preserved a few hours of the occupant's mental patterns. This reduced splinter of personality would be placed in a time-locked Durance with a half-life of more than a million years. The body would then be torched in a solemn ceremony attended only by close relations. A bit of plasma from the immolation was preserved by the appointed Master of the Mantle, who secured it along with the essence in the Durance. The Durance was then given to the closest members of the dead Forerunner's family, who were charged with making sure that it would never be abused. Families and rates were very protective of such places, and tampering with a family Durance was considered sacrilege.
Traditionally, Forerunner space travel involved several rituals. When a Builder family was returning from an interstellar journey, the entire family would stand at the bridge deck and observe the ship's approach. The senior family member would issue commands in ancient Jagon. These actions were entirely ceremonial, as nearly all Forerunner ships were controlled by an ancilla.
After making a slipspace jump, Forerunners of high position, including Councilors, would conduct a ceremony where they formally congratulated the ship's ancilla and would in turn receive a small golden disk containing the cost of particle reconciliation for the journey.
During prolonged space journeys, Forerunners would often play "diverting games" through their armor to pass the time.
The Forerunners' technological achievements were without parallel in the known galaxy. They managed to create solidified surfaces out of light by using technology known as hard light, use slipspace to teleport between locations almost instantaneously, and create numerous forms of advanced machinery. Another of their greatest achievements is their ability to initiate premature stellar collapses of stars and create planets in less than 10,000 years. The Halo Array and the shield worlds are, above all others, the most significant pieces of surviving Forerunner technology. The planet Onyx and its inner Dyson sphere, Shield World 006, in particular demonstrated both their ability for engineering on a grand scale, and their near-transcendent grasp of slipspace technology. Forerunner technology is remarkably resilient, being able to remain intact for over a hundred millennia.
Even after millions of years, Forerunner technology still advanced at a comparatively rapid rate, with a number of new breakthroughs and developments occurring within even a single millennium. It was believed by some Builders that the Forerunners had possessed more advanced technologies in their distant past that they had later lost during periods of technological regression. This was at least partially true, as demonstrated by ten-million-year-old Forerunner probability mirrors, used for large-scale spacetime reconciliation, and similarly ancient cloaking technology used to obfuscate the interior of an entire star system in the Large Magellanic Cloud.
They employed a wide variety of artificial intelligence constructs, generally known to them as ancillas. These ranged from simple personal assistants integrated in their armors to various kinds of robotic Monitors and immensely powerful metarch-level AIs, of which the most sophisticated type was the Contender-class.
The Forerunners had mastered the use of various energy fields, including buffer fields which they used to manipulate gravity, constraint fields used to restrain individuals, confinement fields used to block the movement of entire ships, and the containment and collection fields they used to harness entire stars for energy production. Entire planets could be made habitable even in conditions of lethal stellar radiation via planetary shields.
The Forerunners had an unparalleled knowledge of quantum science, which enabled them much of their sophisticated technology. After a number of instances of catastrophic data loss in their history, they had abandoned conventional digital storage in binary code entirely in favor of storing information in substrates of quantum foam. Virtually all Forerunner technology was powered by harnessing and draining the energies of untold numbers of nascent alternate realities in the form of vacuum energy. This enabled the Forerunners to harness enormous amounts of energy, with a single slipspace-based transmission noted as requiring more energy than the generation capacity of all UNSC assets combined.
In addition to their superior grasp of slipspace travel, the Forerunners had mastered many other methods of higher-dimensional manipulation. They were capable of altering the fabric of time and space within contained "bubbles" of slipspace, allowing the storage of enormous masses and volumes within a comparatively tiny space; as an extreme example, the 300-million-kilometer Shield World 006 was held in a space only 23 centimeters in diameter in normal space. In these bubbles, the flow of time could be suspended altogether, or numerous millennia could be made to transpire while only seconds had passed in normal space. The Forerunners routinely employed the higher dimensions of slipspace in their fleet engagements and created defenses which extended into slipspace, most prominently the Maginot Line.
Forerunner technology could also produce certain objects remarkably quickly without extensive production facilities. For example, personal armor could be manufactured by small engineering units onboard a starship, and entire ships could be "grown" from a "design seed", being manufactured on-site from preprogrammed "blueprints" and construction materials obtained from local resources. Likewise, certain automatons — such as Promethean Crawlers — could be "conjured" on-site and constructed in a matter of seconds from raw materials present in the ground. Most Forerunner technology could disassemble and reconfigure itself into a completely different form, and automatically gather any additional construction materials if necessary; this was demonstrated when the Librarian had a Gargantua-class transport use both itself and resources mined locally to construct the Portal at Voi. The Forerunners did use dedicated production plants for large-scale industry. An example of this is the vast Sentinel manufacturing facility on Onyx, which could produce a new Sentinel every six seconds.
The Huragok, nanomechanical "supercomputers" created by the Forerunners for the purposes of maintaining their technology, remained behind after the activation of the Halo Array. Many were eventually incorporated into the Covenant.

Forerunner spacecraft used special crystals embedded in their slipspace drives to travel through slipspace. In order to move through ordinary space, they utilized reaction drives which harnessed virtual particles as a propulsive force; however, they still required the use of onboard reaction mass. The reaction drive of a mere automated cargo transport allowed travel from Edom to Erde-Tyrene, (a distance of 100 million kilometers at the time), within forty-eight hours; this was considered a mundane trip that did not warrant slipspace manipulation. In addition, the Forerunners created a network of slipspace portals for high-traffic slipspace transit across the galaxy. Aboard starships, limited inertial dampening was achieved through the use of buffer fields, but during extreme acceleration, the occupants' armors had to be locked to the deck.
Forerunner warships could be enormous in scale; the most recent models of Fortress-class vessel were around a hundred kilometers in length, while the Didact's personal command vessel, Mantle's Approach, was 341 kilometers in height and was even then surpassed in size by the largest Forerunner ships.
The interiors of all Forerunner ships were not entirely composed of matter; for example, the structure of a planet-breaker was only half matter, with one third being fuel and reaction mass and the rest being comprised of hard light, allowing the captain to configure the ship's internal layout and decoration at will. At least some types of Forerunner craft can alter their geometry to better suit their current situation; for example, making the ship more aerodynamic in preparation for surface landing.
Communications and sensors
Forerunners used a type of quantum entanglement for communications, allowing instant data transfer over vast distances. These communications were routed over proprietary encryption protocols, which could be used to track the source or destination of the communication. Forerunners did not use electromagnetic radiation (light, radio, microwaves, etc.) to communicate, presumably due to latency, interference, and security issues. They also used a form of superluminal communication involving wormholes; however, these communications were significantly slower than communication via the Domain.
Forerunner sensors were capable of instantaneous scanning and detection across interstellar distances. As a particularly impressive example of their available sensor ranges, the Forerunners' core authority routinely tracked individual slipspace jumps across the galaxy. They were also capable of viewing various alternate spaces adjoining the physical universe—including denial of locale, natal void, shunspace, trick geodetics and a photon-only realm known as the Glow—and ascertaining events or objects in normal space through their signatures sometimes visible in these realms. Forerunners shipboard sensors were also highly accurate, being capable of providing a detailed analysis of a single planet's geological and ecological composition from lightyears away through the use of long-range entanglements.
The Forerunner government used an automated network to collate data from all technological equipment across their ecumene, from mundane devices such as a jetbrush to communications satellites and space stations; overseen by non-intelligent automatons, the system filtered unusual observations and relayed possible significant anomalies to the authorities, specifically the Prelate. Such anomalies included catastrophes or "Xenovents" - supposedly referring to contact with alien lifeforms. This is how the Forerunners first learned of the Flood's reemergence around 97,745 BCE.
"Luminaries", which were originally designed to pinpoint Forerunner technology, were used to find "relics" by the Covenant. They are also capable of locating Reclaimers. A misunderstanding of a Luminary's readings led to the outbreak of the Human-Covenant War.
Forerunners utilized various camouflaging technologies, including dazzlers, which generated visual and auditory delusions, or bafflers, which created geometric distortions that could effectively hide a large area not only from plain sight, but also a starship's sensors. Cloaking systems were standard on most warships, ranging from small attack harriers to enormous command ships like Mantle's Approach. While ships could not use their energy weapons or projectiles while cloaked without giving away their position, gravitic weaponry allowed the ship to remain undetected.
- Main article: Mind transfer
The Forerunners were capable of extracting an individual's complete mental and biological patterns and memories, which could then be encoded in either another biological body or stored as data. A Forerunner could create an offshoot of their consciousness housed in an ancillary system, as the Librarian did on Requiem. An individual's pattern could also be imprinted over another body; an example of this was the Ur-Didact's creation of the IsoDidact. Typically, a dead Forerunner's final memories were recovered and stored in a time-locked container known as a Durance. An abstracted consciousness could also be used as a template for an ancilla; 343 Guilty Spark was created in this manner.
The Forerunners had the technology to reproduce entire individuals from encoded DNA/RNA/silicon samples in data streams. This was the primary manner of indexing biological beings during the Conservation Measure; due to their lack of resources, the Lifeworkers were forced to reduce most specimens into data, although their patterns and memories would be reconstituted during the reintroduction. Recovered essences or specific commands could also be coded into a sentient being through a genetic imprint known as a geas, which could potentially be passed on for numerous generations, with encoded memories or actions programmed to trigger under specified circumstances.
As part of an effort to protect themselves against the Flood, the Forerunners created a machine known as the Composer. Designed to process Flood victims en masse, the Composer also reduced its targets to ash, denying the Flood access to any biomass. In the original plan, new bodies would be created for the abstracted individuals, now free of infection. However, the Forerunners never mastered the process and the victims' original forms could no longer be restored. The Composer was later used by the Didact in an attempt to create an army of Promethean war machines, which led to his imprisonment on Requiem.
The Forerunners used a broad variety of weapons, encompassing various forms of directed energy weaponry as well as electronic warfare and offensive technologies based upon energy fields. Forerunner energy weapons proved to be very effective when battling the Flood, burning Flood forms to the point that they cannot be revived by infection forms. Additionally, after the Flood's emergence, certain weapons were designed to disintegrate their targets upon inflicting a critical hit, preventing the Flood from making use of any biological matter.
Forerunner infantry weapons utilize various forms of ammunition, including hard light, accelerated beams of ionized particles, antimatter, or combinations thereof. Although many, such as the Scattershot and Lightrifle, fill relatively basic roles and have clear analogues in human weaponry, many of these weapons also have exotic properties, such as the Scattershot's ricocheting projectiles or the Boltshot's secondary burst function. Forerunner ground forces also use pulse grenades which generate an energy-drain field before collapsing, destroying any targets within its effective radius. In most contexts these weapons are operated by dedicated automatons, one example of which are the bipedal armiger constructs. When participating in combat operations, the biological Forerunners themselves used advanced exoskeletons called combat skins which ranged greatly in size and capability from more conventional, ground-based battle suits to much larger infantry armatures that were capable of spaceflight, such as war sphinxes and seekers.
The many varieties of Forerunner sentinels carry a wide array of weaponry. The Aggressor Sentinels use moderately effective beam weapons, which can also be wielded by humans and certain Covenant races. Meanwhile, Enforcers are equipped with missile launchers and a pair of pulse beams, which fire clusters of smaller red Needler-like projectiles or bolts of energy at an incredibly high rate of fire. The Sentinels of Onyx had significantly more powerful weaponry and shielding. Their energy weapons functioned via a single, slow-charging, extremely powerful golden beam which was effective against energy shields and armor alike. The Forerunners also constructed stationary automated turrets, resembling stripped-down sentinels. Monitors are capable of defending themselves with high-powered pulse weapons akin to those used by Sentinels, as well as with gravity manipulation technology. As one example of Forerunner weapons technology, certain types of beams could be merged together into one stream to amplify its power; this capability was used on both infantry weapons as well as starship weaponry.
Forerunner weapons are manufactured out of various forms of exotic matter on an atomic level in hyper-precise nanofabrication forges in accordance with instructions programmed into design seeds by Forerunner pattern-weavers working in conjunction with an ancilla. Because of the fidelity of these manufacturing methods, every weapon and piece of technology could be built perfectly identical down to the atomic level. While the Builders designed most of their technology to be highly uniform, the Warrior-Servants preferred to craft their weapons and armor to be unique and aesthetically pleasing whenever possible. However, the Warrior tradition of custom-crafted equipment waned almost completely as the Forerunners' war with the Flood became increasingly desperate, leaving little room for design considerations beyond lethality and efficiency. Forerunner firearms, like the rest of their technology, are highly sophisticated; most are composed of disparate parts held together by energy fields and display self-assembling capabilities. At least some Forerunner weapons are designed to operate differently according to their wielder; for example, the Incineration Cannon known as the River of Light will only unlock its full capabilities in the right hands while reducing its destructive power when wielded by a Promethean Knight construct.
Art and architecture
Forerunner architecture incorporates heavy use of geometric angles, usually at either extremely sharp degrees - Forerunner buildings are usually trapezoidal - or at forty-five degree angles. Most Forerunner architecture is constructed with a special type of silver-gray metal that resists deterioration, bullets, plasma bolts and fire, as made evident by Forerunner structures standing in pristine condition 100,000 - 150,000 years after they were built. However, their resistance to heavy plasma fire is limited; concentrated plasma discharge is capable of destroying some Forerunner architecture. Other structures and certain starships were built with a golden-bronze colored metal.
The Forerunners were also highly skilled at creating stone architecture. Typically, these buildings were built from a pale brown or tan stone. These structures were more subject to wear and aging, but their architectural sophistication remains apparent after 100,000 years. A particularly prominent example of intact Forerunner stone architecture could be found within Onyx's Zone 67, which contained a massive Forerunner city constructed entirely of polished chalcedonic quartz. In some structures, such as the Forerunner complex beneath Reach's Menachite Mountain, patterns and symbols had been embedded in the rock itself by manipulating its mineral inclusions. Most interestingly, certain Forerunner buildings incorporated "mutable" stonework: a stone Forerunner structure in Ontom, Sanghelios featured passages that could shift and change by literally reshaping the stone from which their walls were built.
In addition to physical structures, a large portion of Forerunner architecture is actually composed of sophisticated hard light construction. Such architecture is often crafted in the likeness of corporeal matter, most commonly gray Forerunner metal. Hard light structures can form complex shapes and in many cases, be entirely indistinguishable from physical construction, making it difficult to determine which structural components are made up of actual matter. This technology has many uses, from acting as basic structural components such as platforms or walls to decorating and furnishing everything from Forerunner homes and public spaces to starship interiors. Many Forerunner structures are capable of materializing when needed and then melting away when deactivated, a feature most likely facilitated through the use of hard light. The immaterial and flexible nature of this technology lends it a great deal of uses, but as a drawback, it is susceptible to power failures; nonetheless, certain Forerunner ships, such as the command warship Mantle's Approach, employ hard light bonding as a means of maintaining the vessel's structural integrity. Some Forerunner structures, including many of those on Requiem, incorporate components which float in the air without any physical support.
Many symbols and patterns on Forerunner structures employ complex geometric shapes that appear to operate in dimensions higher than human understanding can comprehend. The Forerunners also decorated the interiors of their structures with a complex pattern of engraved straight lines and applied decorative touches and designs to nearly everything that they built, from structures to weapons. Even Sentinel drones possess small holographic Forerunner script around their "eyes". Some Forerunner structures, most prominently those on Requiem, mark bullet holes and other forms of weapon strike points with a small glyph automatically etched around the damaged portion of the surface within moments of the impact.
The Forerunners were highly skilled at creating natural-looking habitats, such as those of the Halo installations, which tend to be very elaborate and include realistic weather patterns and self-sustaining biomes. Although they are clearly distinct from the natural landscape, Forerunner structures often appear to "grow" out of the surrounding terrain, resulting in an impression of complementing the landscape as opposed to replacing it.

While the Forerunners' architectural and technological prowess is legendary, their masterpieces also extended to the fields of stellar and planetary engineering.
Shield World 006, a full-size Dyson shell, existed in slipstream space, where planets and stars cannot ordinarily exist. In addition, the slipspace bubble containing the enormous construct was enclosed within Onyx, a planet-sized structure composed of trillions of Sentinels arranged into a complex structural scaffolding and covered by a terrestrial crust. The Forerunners also created many smaller shield worlds, essentially planet-sized Dyson shells with terrestrial inner and outer surfaces as well a miniaturized sun in the center. Some works of Forerunner engineering are also located beyond the confines of the galaxy, including Installation 00, a vast, flower-shaped construct with a terrestrial surface and its own artificial star for illumination. Another example of the Forerunners' mastery of megascale engineering was the Capital, a structure which surpassed even the Ark in sheer enormity and complexity.
In addition to moving and manipulating stars for use in their megastructures, Forerunner Miners, specifically stellar-class engineers known colloquially as "plasma jockeys", experimented with stabilizing young stars. The Forerunners had also harnessed dozens of stars for energy production by using sophisticated energy fields to direct the energy output of a star. Specialized plasma jockey installations were also capable of suspending the collapse of a star, although this was rarely entertained due to the enormous amounts of energy required in the process. In addition to stellar manipulation, the Forerunners were capable of considerably speeding up a planet's formation, artificially collapsing an asteroid field into a molten mass, then cooling it down and forming it into a terrestrial planet in less than ten thousand years; a relatively short period of time for the ageless Forerunners.

- According to Bungie employee David Candland,, Bungie's intentions for the connection between humanity and Forerunner was that they were one and the same; this was hinted repeatedly throughout the Halo Trilogy and further explored in Staten's novel, Halo: Contact Harvest. The books of The Forerunner Saga released by 343 Industries have since revised this, establishing that the two species were related but distinct and that the actual connection goes far further back than the events in the books, when both species had been created by the Precursors.
- Bungie environment artist Paul Russel was largely responsible for establishing the Forerunners' architecture and aesthetic. He cited some of his influences as being sails and movie marquees, as well as the works of American architect Frank Lloyd Wright; in particular, Wright's use of cantilevers and stained glass windows with repeating geometric patterns of lines in complementary angles. Russel jokingly stated that "I also like the idea of Forerunner columns being sausages meticulously and gorgeously wrapped in bacon by Frank Lloyd Wright's genetic precursor. Now that is a tall tale. Because as far as I know, Forerunner architecture is inedible—unless the fans say otherwise."
- The Forerunners show some similarities (their highly advanced technology and the fact that they mysteriously vanished) to the Jjaro, a race of aliens from a previous Bungie game, Marathon. The concept of a highly advanced extinct race leaving technological relics behind is not a new concept and is indeed a fairly common element of science fiction of all media, from books, to films.
- The Forerunners were the main focus of the alternate reality game, Iris.
- The Forerunner Saga, a trilogy of books based on the Forerunners' culture and their war with the Flood was written by Greg Bear. The first of these books was released on January 4th, 2011, titled Halo: Cryptum, while the second novel, Halo: Primordium, was released on January 3, 2012. The third book, Halo: Silentium, was released on March 19th 2013.

List of appearances
- ^ It is never directly stated that the Forerunners' armor granted them truly indefinite lifespans, although this can be inferred from several statements in The Forerunner Saga. In Halo: Cryptum, Bornstellar notes that Forerunners died only on rare occasions, usually by accident or during war (Cryptum, page 47). In Halo: Silentium, the Librarian mentions having visited the collection of a former Theoretical on Keth Sidon (Silentium, page 67); since the Theoretical rate was dissolved a million years earlier, the former Theoretical would have been at least a million years old at the time, although it is not explicitly stated that the Theoretical in question was still alive. Nonetheless, Halo 4: The Essential Visual Guide asserts that the Composers were originally designed to transfer old essences into youthful bodies. While this may seem rather trivial given the Forerunners' effective immortality, it is known that older members of the species (such as the Confirmer) could become significantly disfigured with age. The Composer entry on Halo Waypoint reiterates The Essential Visual Guide's statement and further reveals that composed essences may have been integrated into the Domain, granting them true permanence.

- ^ halo.bungie.org: Re: Why retcons don't bother me anymore (Evil Otto: "One of the most striking retcons to me is the basic concept of whole role of humanity. Originally (back in Halo 1) the reason why humans weren't conquered and incorporated into the Covenant collective was because their presence defied Covenant religion. When the Covenant discovered humans, they knew they were forerunners, but their presence implied the "great journey" failed. They also weren't the all powerful gods they worshiped, so the Prophets wanted to "sweep them under the carpet," as it were.")
