==Primordial Era==
*Over '''500,000,000 BCE''', the [[Precursor]]s are stated by the [[Gravemind]] to have created the [[Domain]],<ref>'''Halo: Silentium''', ''pages 208-209''</ref> coalescing the sum of their knowledge—encompassing a hundred billion years—into a unified reservoir integrated into their many [[neural physics]] artifacts in the [[Milky Way]] galaxy. However, the Domain may have been first created long before this, as [[Forthencho]], acting as a messenger for the Gravemind, later stated that it had existed for many billions of years.<ref>'''Halo: Silentium''', ''page 322''</ref>
==Forerunner era==
*Circa '''15,000,000 BCE''', the [[Precursor]]s create and seed the species that would come to be known as [[Forerunner]]s on the planet [[Ghibalb]].<ref>[https://www.halowaypoint.com/en-us/universe/species/forerunners '''Halo Waypoint''': ''Forerunners'']</ref>
*Circa '''10,000,000 BCE''', the [[Precursor]]s choose early [[human]]s to be the next species to carry the [[Mantle]]. Desiring to seize the Mantle for themselves, the early [[Forerunner]]s [[Forerunner-Precursor war|rebel against the Precursors]] and wipe them out almost entirely.<ref name="s181">'''Halo: Silentium''', ''page 181-182''</ref> After the Forerunners hunt down all of the Precursors in the [[Milky Way]] galaxy, the remains of the race retreat into the [[Large Magellanic Cloud]]; the Forerunners' [[Warrior-Servant|Warrior]] fleets pursue them via [[probability mirror]]-reconciled [[slipspace portal]]s and proceed to finish their work. A number of Forerunners who conscientiously object to the complete destruction of the Precursors are exiled on a barren planet within the [[Tarantula Nebula]]; these Forerunners later remain as the [[Path Kethona Forerunner|only surviving population]] of the expedition to the Large Magellanic Cloud.<ref>'''Halo: Silentium''', ''page 179''</ref>
*In the face of extinction, most of the Precursors reduce themselves to inert powder, intending to regenerate their forms later. However, this dust would deteriorate over the coming eons, eventually bringing forth the parasitic [[Flood]].<ref>'''Halo: Silentium''', ''page 174''</ref> However, [[Primordial|one intact specimen]] remains in deep stasis and is buried within a remote [[asteroid]] a million years afterward.<ref name="s181"/>
*Circa '''9,000,000 BCE''', the [[Primordial]], a dormant [[Precursor]],<ref>'''Halo: Silentium''', ''page 181-182''</ref> is said to have arrived on the edges of [[Milky Way|the galaxy]]. This being is later discovered by [[Prehistoric human civilization|early spacefaring humans]] during the last decades of the [[Human-Forerunner War]] and brought to [[Charum Hakkor]] in a [[stasis capsule]].<ref>'''Halo: Silentium''', ''page 173''</ref>
*Prior to '''1,100,000 BCE''', [[ancient human]]ity achieved its earliest known spacefaring technological state and settled on numerous worlds along the galactic margin.<ref name="sil">'''[[Halo: Silentium]]''', ''pages 67-68''</ref> They would later experience several dark ages resulting in the loss of most of their historical records and knowledge before eventually encountering the Forerunners.<ref>'''[[Halo: Primordium]]''', ''page 237-238''</ref>
*Around 1,100,000 BCE, the [[Forerunner]] [[Rate#Theoretical|Theoretical]] known as [[Boundless]] begins to study a particular star within the [[Path Kethona]] galaxy. When she continues her work in defiance of [[Warrior-Servant|Warrior]] orders to the contrary, she is eventually prosecuted, her studies are suppressed, and she is forced to enter a [[Cryptum]].<ref name="sil"/>
*A thousand years later, Boundless' Cryptum is opened and it is discovered that she has died inside due to a malfunction in the Cryptum, supposedly resulting from sabotage. Her former students discreetly dispose of her body.<ref name="sil"/>
*After Boundless' death, the entire Theoretical [[rate]] is absorbed into the [[Builder]]s.<ref name="sil"/>
*Circa '''150,000 BCE''', the [[Forerunner]]s are claimed by some records to have risen as the preeminent species in the [[Milky Way Galaxy]] by advancing technological discoveries gathered from the remnants left by prior ancient races. Believing themselves responsible for the lives of all those less advanced then they, the Forerunners initiate the [[Mantle]].<ref>'''[[Halo Encyclopedia]]''', ''page 26''</ref><ref group="note">This entry, originating from the ''[[Halo Encyclopedia]]'', is of dubious accuracy in light of information from ''[[The Forerunner Saga]]'', in which the Forerunners are stated to have been spacefaring for millions of years (albeit having experienced a number of technological dark ages and large-scale record loss events over the course of this period) and that they held the Mantle since [[10,000,000 BCE]], having forcibly seized it from the [[Precursor]]s. However, the ''Encyclopedia'' notes that ''"all Forerunner era dates are approximate, based on available translation and scattered historical data"'', which provides a canonical explanation for the possible inaccuracies of this entry.</ref>
*[[Human]]ity is believed by the Forerunners to have "moved their [[Prehistoric human civilization|interstellar civilization]] outward along the galactic arm" around this time, possibly to escape Forerunner control.<ref>'''[[Halo: Cryptum]]''', "chapter 1", (''"She responded that to the best of Forerunner research, humans had indeed first arisen on Erde-Tyrene, but over fifty thousand years ago had moved their interstellar civilization outward along the galactic arm, perhaps to flee early Forerunner control. Records from those ages were sparse."'')</ref>
*The [[capital]], the center of the [[Forerunner]] [[ecumene]], is constructed around this time.<ref>'''[[Halo: Cryptum]]''', ''page 296''</ref>
*[[Faber-of-Will-and-Might]], a future [[Master Builder]], is born this year.<ref name="HWFaber">[https://www.halowaypoint.com/en-us/universe/characters/master-builder '''Halo Waypoint''': ''Faber'']</ref>
*[[Ur-Didact|Shadow-of-Sundered-Star]], later known as the Ur-Didact, is born this year.<ref name="waypoint didact">[https://www.halowaypoint.com/en-us/universe/characters/didact '''Halo Waypoint''': ''Didact'']</ref>
*Circa '''107,445 BCE''', [[Prehistoric human civilization|human]] colonists proceed to uncover crashed vessels containing [[Flood spores|fine organic powder]] on both inhabited and deserted worlds near the edges of the [[Milky Way|Milky Way Galaxy]]. This powder is administered to the domesticated [[Pheru]], which begin to exhibit more docile behavior; unbeknownst to humanity and their [[San'Shyuum]] allies, the powder begins to alter the Pheru's genetic makeup. Centuries later, the Pheru begin to show outward signs of mutation and cannibalize one another. Soon, both humans and San'Shyuum who are exposed to the powder begin to exhibit the same symptoms.<ref>'''Halo: Cryptum''', ''page 267-269''</ref>
*The [[Flood]] then begins to take over hundreds of worlds, turning its victims into misshapen forms. Humanity begins all-out war against the Flood. During their war against the Flood, humanity desperately invades a minor sector of Forerunner space, sparking the [[human-Forerunner wars]].<ref>'''Halo: Cryptum''', ''page 272''</ref>
*Circa '''106,538 BCE''',<ref group="note">''Halo: Primordium'' specifies that the Primordial was discovered 40 years before "the last of the human-Forerunner wars". This is assumed to refer to the final [[Charum Hakkor campaign|53-year conflict]] fought mainly in the [[Charum Hakkor system]], as this is the longest mentioned continuous conflict which can be reasonably said to fall within the "few extra decades" Yprikushma bought humanity with her subsequent work.</ref> [[Prehistoric human civilization|human]] colonists arriving at a ravaged planet on the edge of the [[Milky Way|Milky Way Galaxy]] discover an exceedingly ancient [[stasis capsule]]. This capsule is the prison of the ancient being known as the [[Primordial]], supposedly the last intact [[Precursor]]. [[Yprin Yprikushma]] transports the capsule and its prisoner to [[Charum Hakkor]] for further study.<ref name="prim236">'''Halo: Primordium''', ''pages 236-238''</ref>
*Yprikushma's science teams revive the Primordial and place it in a [[timelock]] held in a [[Charum Hakkor arena|vast arena]] on Charum Hakkor, soon after devising a way to communicate with the creature. The answers given by the Primordial to the humans' questions about the [[Flood]] are so traumatizing they are believed by [[Forthencho]] to have demoralized humanity to the point of contributing to their defeat against the Forerunners later on.<ref name="prim236"/>
*Yprin Yprikushma begins to push humanity to conduct more intensive research into [[Forerunner]] technologies recovered during earlier human-Forerunner conflicts. Through the technological advances gained, she buys humanity several more decades in its [[Human-Forerunner War|war with the Forerunners]].<ref name="prim236"/>
*Some time afterward, the [[Flood]] begins to recede from the galaxy; while this is thought to be due to a cure created by humanity, no cure ever actually existed; the Flood's withdrawal is instead due to the [[Gravemind]]'s long-term strategy.<ref>'''Halo: Primordium''', ''page 364''</ref> With the Flood seemingly dying out, all traces of the parasite's existence are eventually removed from the Milky Way by humans, their [[San'Shyuum]] allies, and Forerunner Warrior-Servants.<ref>'''Halo: Silentium''', ''pages 34-37''</ref> Throughout the war, most Forerunners remain unaware of the Flood's existence, believing stories of the parasite to be an excuse for humanity's aggressive expansion. The Flood will not seen again for nine millennia.<ref>'''Halo: Cryptum''', ''pages 270-272''</ref>
*Circa '''106,498 BCE''',<ref>'''Halo: Primordium''', ''page 234''</ref> [[Charum Hakkor campaign|the final conflict]] in the [[Human-Forerunner War|human-Forerunner wars]] begins. The [[Forerunner]] [[Warrior-Servant]]s, led by the [[Ur-Didact|Didact]], push [[prehistoric human civilization|humanity]] back to the [[Charum Hakkor system]], the core of their interstellar empire, which is then effectively cut off from available reinforcements of both humans and their [[San'Shyuum]] allies. For the next fifty years, humanity holds off attacks by the [[Forerunner fleet]]s,<ref name="cryptum">'''Halo: Cryptum''', ''page 118''</ref> until their defenses eventually fail after three final years of repelling assaults on the system in a constant stream.<ref>'''Halo: Primordium''', ''pages 239-240''</ref>
*Circa '''106,445 BCE''', the final battles of the [[human-Forerunner wars]] are fought, concluding in the humans' [[Charum Hakkor campaign|standoff]] at [[Charum Hakkor]].<ref>'''Halo: Cryptum''', ''page 131''</ref> Stretched thin due to fighting two wars simultaneously, humanity loses the war and the Forerunners eliminate all traces of humanity's former [[Prehistoric human civilization|interstellar civilization]]. The [[Librarian]] moves the surviving humans to their homeworld, [[Earth|Erde-Tyrene]], and establishes a research station there. With their civilization and technology dismantled, humanity regresses to tribal hunter-gatherers for nearly nine thousand years, eventually developing [[Erde-Tyrene civilization|primitive civilization]].<ref>'''Halo: Cryptum''', ''page 55''</ref>
*Circa '''98,445 BCE''' (approximately a thousand years prior to the firing of the [[Halo Array]]), the [[Forerunner]] [[Promethean]]s, opposed to the construction of the Halo rings, lose their political battle against an extreme faction of the [[Builder]]s led by the [[Master Builder]], [[Faber]], and are forced out of the [[Ecumene Council|Council]]. Many are disgraced or executed while others choose the alternative of exile in a [[Cryptum]]. For the next thousand years, the Council continues to marginalize and diminish the role of the entire [[Warrior-Servant]] rate.<ref name="c238">'''[[Halo: Cryptum]]''', ''pages 238-239''</ref>
*The [[Ur-Didact|Didact]] enters his first, thousand-year exile in a Cryptum on [[Nomdagro]].<ref>'''[[Halo: Silentium]]''', ''String 4''</ref> The Cryptum is later secretly moved to [[Earth|Erde-Tyrene]] by the [[Librarian]].<ref>'''Halo: Cryptum''', ''page 81''</ref>
*The ''[[Deep Reverence]]'' is retired near [[Janjur Qom]], under the care of the [[Confirmer]].<ref>'''Halo: Cryptum''', ''page 180''</ref>
*With the final obstacle to his plan removed, Faber commissions the construction of the original twelve [[Halo Array|Halo rings]] from the [[guild]] of [[Bornstellar's father]].<ref name="c238"/>
*[[Growth-Through-Trial-of-Change]] decides to become a [[Lifeworker]] instead of a Builder. She is rejected by her family as a result, and is adopted by a foster family.<ref>'''[[Halo: Rebirth]]'''</ref>
*Circa '''98,395 BCE''',<ref>'''Halo: Silentium''', ''page 163''</ref> the [[Librarian]] undertakes on a mission to study the origins of the [[Flood]] in the [[Magellanic Clouds|satellite galaxy]] of [[Path Kethona]]. In Path Kethona, the Librarian and the crew of her explorer vessel, ''[[Audacity]]'', discover a world with a population of [[Path Kethona Forerunner|primitive Forerunners]]. On this planet, she learns the truth about the [[Precursor]]s' disappearance ten million years earlier: the Forerunners [[Forerunner-Precursor war|rose up against]] their creators and annihilated them in defiance of the Precursors' choice to pass the [[Mantle]] on to [[human]]ity.<ref>'''Halo: Silentium''', ''page 181-182''</ref> The Librarian would keep this information to herself at the time, fearing that the [[Builder]]s in control of the [[Ecumene Council|Old Council]] could potentially use it against her or the [[Ur-Didact|Didact]].<ref>'''Halo: Silentium''', ''page 29''</ref>
*Circa '''97,745 BCE''', first contact is made between the [[Forerunner]] [[Primary Pioneer Group]] and the [[Flood]] on [[G617 g1]]. A military team is sent in later but is subsequently lost. The Flood escapes the planet, thus beginning the three-century-long [[Forerunner-Flood war]].<ref>'''[[Halo 3]]''', ''[[Terminal/Halo 3#Terminal Two|Terminal Two]]''</ref>
*The [[Z-110 Directed Energy Pistol/Exotic|Boltshot]] comes into use with the [[Forerunner]] military near the beginning of the century.<ref>[http://blogs.halo.xbox.com/Headlines/post/2012/09/26/The-Halo-Bulletin-92612-.aspx '''Waypoint''': ''The Halo Bulletin: 9.26.12'']</ref>
*[[Riser]] is born in the city of [[Marontik]] on [[Erde-Tyrene]] around this time.<ref>'''[[Halo: Cryptum]]''', ''page 35''</ref>
*In approximately '''97,495 BCE''' or slightly earlier,<ref group="note">The Halo Array was fired in [[97,445 BCE]]. Mendicant Bias' test-firing of Installation 07 and the Halo's subsequent disappearance took place 43 years before the installation's return during the events of ''Halo: Cryptum'' (''Halo: Cryptum'' page 244 and ''Halo: Primordium'' page 192). ''Halo: Cryptum'' takes place a minimum of seven years before the firing of the Halo Array, which can be extrapolated from a number of statements in ''Halo: Silentium'':<br><br>
It is implied in the description and beginning of ''Halo: Silentium'' that the novel begins several years after the end of ''Halo: Primordium''. On page 193, while testifying to the [[Master Juridical]], Master Builder Faber states that he and his forces held a salient against the Flood for three years after Mendicant Bias' [[Battle of the Capital|attack on the Capital]]. Since the Master Juridical would know how long Faber had been missing since the fall of the Capital, it would be futile for the latter to claim that he had been running his private operation for ''more'' than the time he had been confirmed to be missing. As such, his statement about holding off for three years can be considered the minimum figure for the duration of his exile. However, it should be noted that Faber may have remained missing for more than that time, as the three years of holding that particular salient may have constituted only a portion of the operations he undertook during his exile.<br><br>
Faber's testimony took place after his return to the ecumene, which coincided with his rescue of the [[Ur-Didact]]. As stated on page 28 of ''Silentium'', the Ur-Didact's return had already occurred some time prior to the evacuation of Erde-Tyrene and the Librarian's deposition by [[Catalog]]. There is a four-year period between the Librarian's and the IsoDidact's parting during the evacuation of Erde-Tyrene and their reunion on Nomdagro (''Silentium'', page 197). Although it is not definitely stated how much time passes between the meeting on Nomdagro and the firing of the Halo Array, the almost continuous recounting of the events past Nomdagro up until the Halos' activation in ''Silentium'' would suggest no more than several days or weeks passed in the interim. However, this does not take into account the possibility of increased time dilation effects due to the Precursor-empowered Flood's corruption of spacetime, which interfered with the Forerunners' slipspace travel in the final years of the war.<br><br>
The year 97,495 BCE for Installation 07's disappearance is calculated on the basis that seven years passed between the events of ''Halo: Cryptum'' and the firing of the Halos, therefore indicating that the events described on this page took place fifty years before the firing of the Array. Due to several ambiguities it is possible that the events took place several (though likely no more than five) years earlier than this, but anything beyond the known minimum figure remains in the realm of speculation. It should be noted that the ''Halo Encyclopedia'' lists Mendicant Bias' conversation with the Gravemind as having begun on 100,043 BCE, or 43 years before the approximate date for the firing of the Halos. However, because the ''Encyclopedia'' itself notes that the timeline is only approximate and due to the manifold revisions to Forerunner-era canon introduced by ''The Forerunner Saga'', the information from the novels can be considered to be of superior canonicity to the more unreliable and rough dating provided in the ''Encyclopedia''.</ref> the [[Forerunner]] [[Ecumene Council]] assigns the [[Contender-class artificial intelligence|Contender-class]] [[ancilla]] [[Mendicant Bias]] to test [[Installation 07]] near [[Charum Hakkor]]. The installation, fired on a system-wide power setting, destroys all neurologically complex life and [[Precursor]] structures in the [[Charum Hakkor system|system]] and accidentally liberates an ancient [[Gravemind]] known as the [[Primordial]], which is transported on the ring on [[Master Builder]] [[Faber]]'s orders. Soon after, Faber tasks Mendicant Bias with interrogating the Primordial and Installation 07 is transported in an unknown location. Over the course of their 43-year conversation, the Primordial manages to turn Mendicant Bias against its makers and causing it to join the Flood's cause to destroy the Forerunners.<ref>'''Halo: Primordium''', ''pages 190-192''</ref>
*At the same time the [[Librarian]] returns to [[Earth]] to index the [[human]] species. Sample members of the species are removed from the planet and held on the [[Installation 00|Ark]].<ref name=HE>'''[[Halo Encyclopedia]]''', ''page 27''</ref>
*In '''97,445 BCE''' the [[Forerunner-Flood war]] came to a close with the activation of the [[Halo Array]].<ref name="canon fodder">[https://www.halowaypoint.com/en-us/community/blog-posts/canon-fodder-array-with-words '''Halo Waypoint''': ''Cannon Fodder - Array With Words'']</ref> It should be noted that all of the events listed here are approximate at best, occurring over the course of several years during the last decade<ref name="caveat">'''Halo: Silentium''', ''page 11-12''</ref> before the firing of the Halo rings in the year 97,445 BCE.<ref name="canon fodder"/><ref group="note">[[343 Guilty Spark]] put the date of the firing of the Array as the year 97,448 BCE, though it should be noted that he measured it on Installation 04's year, not the 365.25 day Earth calendar.</ref> As no definite chronology has been established for that timeframe, the events therein are recorded on this page for the sake of convenience.
*Roughly '''ten years''' before the Flood conflict's conclusion, the father of [[Maker-of-Moons]], a high-ranked [[Builder]], is assassinated by [[Master Builder]] [[Faber]]'s [[Builder Security]] minions.<ref>'''Halo: Silentium''', ''page 90''</ref>
*The [[Librarian]] visits the primary [[San'Shyuum]] quarantine world [[Janjur Qom]] to collect specimens of the San'Shyuum as part of the [[Conservation Measure]], sparking unrest among the San'Shyuum population. After [[Master Builder]] [[Faber]] arrives some time afterward to question the San'Shyuum elders about the [[Flood]], the San' Shyuum [[Battle of Janjur Qom|rebel]] against his forces.<ref>'''Halo: Cryptum''', ''page 212''</ref>
*The [[Ur-Didact|Didact]] is resuscitated from his exile in a [[Cryptum]] by [[IsoDidact|Bornstellar Makes Eternal Lasting]], [[Chakas]] and [[Riser]]. They later make their way to Janjur Qom, where they are captured by Master Builder Faber. The Didact is interrogated and left to die in a Flood-infested system, while an offshoot of his consciousness lives on in Bornstellar's body through an imprint acquired in his [[Forerunner mutation|mutation]].<ref>'''Halo: Primordium''', ''page 336-339''</ref>
*Shortly afterward, the Master Builder orders the [[Contender-class artificial intelligence|Contender-class]] [[ancilla]] [[Mendicant Bias]] to use [[Installation 07]] to put down the San'Shyuum rebellion by sterilizing the entire system.<ref name="p191">'''Halo: Primordium''', ''page 191-192''</ref>
*As a result of the Master Builder's activation of the Halo ring, many [[Lifeworker]]s and [[Warrior-Servant]]s on Installation 07 rebel against his forces, but are mostly defeated.<ref name="p191"/>
*A crisis occurs in the [[Ecumene Council]] due to the Master Builder's unauthorized activation of Installation 07; many councilors resign in protest while younger ones take their place. Faber is arrested and placed on trial in the Forerunner [[Capital]]. Eleven of the Halos are brought to the Capital, awaiting a decision to have them decommissioned. Installation 07 and Mendicant Bias remain missing.<ref>'''Halo: Cryptum''', ''page 245''</ref>
*During Faber's tribunal, Mendicant Bias, convinced to turn against its masters by the [[Primordial]], brings Installation 07 to the Capital system and [[Battle of the Capital|launches an assault]] on the Forerunner government.<ref name="p191"/> While the Council's fleets respond to the attack and several of the Halos are destroyed, Mendicant successfully fires Installation 07 before the Halo is forced to retreat into a system near the galaxy's edges.<ref>'''Halo: Primordium''', ''page 272''</ref>
*Having survived Mendicant Bias' attack on the capital, Bornstellar, [[Glory of a Far Dawn]] and [[Splendid Dust of Ancient Suns]] arrive at the [[greater Ark]], where they are healed by the Lifeworkers. As most Forerunners believe the original Didact to be dead, the Didact's consciousness takes control of Bornstellar in order to assume command of Forerunner military forces after a thousand years of exile and continue his mission against the Flood;<ref>'''Halo: Cryptum''', ''page 341''</ref> subsequently, Bornstellar adopts the title [[IsoDidact]].<ref>'''Halo: Silentium''', ''page 20''</ref>
*Shortly afterward, the IsoDidact and his fleet track down Installation 07. Although the Halo takes heavy damage, it survives and is transported to the greater Ark. Afterwards, the installation is sent to its final location,<ref>'''Halo: Primordium''', ''pages 373-374''</ref> to be later joined by the six rings of the newer Halo Array.
**The Primordial is imprisoned once again, and is interrogated - and eventually executed - by the IsoDidact.<ref>'''Halo: Primordium''', ''page 359-367''</ref>
**Mendicant Bias is captured, deactivated and disassembled to its disparate components which are then distributed across the ecumene.<ref name="mb">'''Halo: Silentium''', ''pages 267-268''</ref>
**The mind of a mortally wounded [[Chakas]] is used as the template for the [[monitor]] later to be known as [[343 Guilty Spark]].<ref>'''Halo: Primordium''', ''page 372''</ref>
*The Ecumene Council is reconstituted as the "New Council" and the Didact's plans of a strategy to use [[shield world]]s to combat the Flood are taken into serious consideration again. The use of the Halos is delayed.<ref>'''Halo: Primordium''', ''page 373-374''</ref>
*For a period of at least '''three years''' following the crisis at the Capital, Master Builder Faber, thought dead by the ecumene at large, carries out his own small-scale campaign to combat the Flood with a crew of Builder Security and disgraced Warrior-Servants in a secluded region of the ecumene. He captures and haphazardly decontaminates small Flood-infested ships and then hands them over to Warrior-Servant crews. Due to inadequate decontamination, many of the ships are overrun by Flood still on board.<ref>'''Halo: Silentium''', ''page 193-195''</ref>
*The [[Juridical]] rate is given unrestricted access to all citizens of the ecumene by the Council, with the mandate to investigate matters surrounding the attack on the Capital, Forerunner and human origins, as well as the fate of the Precursors. To this end, the Juridicals dispatch [[Catalog]] to collect testimony from key Forerunner figures, including the Librarian, Ur-Didact, IsoDidact and Faber.<ref name="caveat"/>
*The [[Ur-Didact]], having been left to die in a Flood-infested system by the Master Builder, encounters active Precursor [[star road]]s near [[Uthera Midgeerrd]]. The Didact is subsequently captured and tortured by the Gravemind.<ref>'''Halo: Silentium''', ''String 12''</ref> Afterwards, the Gravemind releases the Didact, who is rescued and taken to the Capital system by the Master Builder.<ref>'''Halo: Silentium''', ''page 199''</ref>
*The Librarian and the IsoDidact arrive at Earth to oversee its evacuation operation and to give their testimonies to Catalog. However, the Flood's arrival in the sector prompts the IsoDidact to leave to defend the core of the ecumene while the Librarian continues her mission;<ref>'''Halo: Silentium''', ''String 2''</ref> the two will not reunite until four years later.<ref>'''Halo: Silentium''', ''page 197''</ref>
*[[Mendicant Bias]] is reassembled and reactivated by a Gravemind after the Flood overruns the facilities in which the components of the AI were held.<ref name="mb"/>
*[[Catalog]] is captured by the Flood and corrupted with the [[logic plague]],<ref>'''Halo: Silentium''', ''page 210''</ref> subsequently spreading the infection across the [[Juridical|Juridical network]].<ref>'''Halo: Silentium''', ''page 215''</ref> With the network suspended, Juridicals are eventually forced to cease all Forerunner legal proceedings indefinitely.<ref>'''Halo: Silentium''', ''page 190''</ref>
*The Flood begins to reactivate and appropriate formerly dormant Precursor artifacts, allowing them to easily overpower Forerunners in combat. Already weakened and exhausted Forerunner defenses continue to fail at an increasing rate.<ref>'''Halo: Silentium''', ''String 25''</ref>
*'''Over a year''' before the end of the war, following irregular outages for several years, the [[Domain]] goes permanently inaccessible to all Forerunners and ancillas due to the Flood's widespread tapping into its underlying [[neural physics]] architecture.<ref>'''Halo: Silentium''', ''page 241''</ref>
*'''Four years''' after the evacuation of Erde-Tyrene,<ref>'''Halo: Silentium''', ''page 197''</ref> the Librarian, the IsoDidact and the Ur-Didact reunite in their family estate on [[Nomdagro]]. The planet is subsequently overrun by the Flood.<ref>'''Halo: Silentium''', ''page 232''</ref>
*After the Capital system is lost to the Flood, command of the ecumene and the bulk of its remaining population is placed at the [[greater Ark]]. In the face of imminent defeat, the Master Builder is restored to command and a decision is made to use the Halo Array to purge the galaxy of life and thus starve the Flood. The IsoDidact is tasked with carrying out this plan.<ref name="s27">'''Halo: Silentium''', ''Strings 27-33''</ref>
*Mendicant Bias and its fleet of Flood-controlled ships and Precursor constructs [[Battle of the greater Ark|assault the greater Ark]].<ref name="s27"/>
*Anticipating that Omega Halo's human population may be at risk, the Librarian sends [[Chant-to-Green]] to collect more humans from Earth to ensure their numbers will be sufficient to repopulate the species.<ref name="s316">'''Halo: Silentium''', ''pages 316-319''</ref>
*While the Forerunners attempt to evacuate the greater Ark, the Ur-Didact uses a [[Composer]] to harvest the preserved human specimens on the nearby [[Omega Halo]] in order to use their patterns to create AIs for his army of [[Promethean Knight]]s, a desperate and futile effort to combat the Flood via conventional means.<ref>'''Halo: Silentium''', ''pages 262-263''</ref>
*Master Builder Faber fires Omega Halo, sterilizing the local galaxy of [[Path Kethona]] of sentient life and clearing a temporary path past the star roads laying siege on the greater Ark.<ref>'''Halo: Silentium''', ''pages 272-273''</ref>
*The greater Ark and Omega Halo are destroyed by star roads; Faber and most high-ranking Forerunner commanders are killed on Omega Halo, while the IsoDidact is saved by Monitor Chakas.<ref>'''Halo: Silentium''', ''pages 274-275''</ref> Only a fraction of the Lifeworkers' biological specimens survive and are transported to the secret [[Installation 00]] by the few surviving Forerunners.<ref>'''Halo: Silentium''', ''pages 306-310''</ref>

After a brief battle between Ussan Sangheili and boarding Covenant Sangheili and Sentinels, Ussa contacts Inner Conviction and tells him to pull back his forces or they will perish with his soldier when he destroys the shield world. Amazingly, he does just that, although he and other Ussans survive in separate sections.

*In [[wikipedia:Battle of Thermopylae|The Battle of Thermopylae]] of 480 BC, an alliance of Greek city-states fought the invading Persian Empire at the pass of Thermopylae in central [[Wikipedia:Greece|Greece]]. Vastly outnumbered, the Greeks held back the massive army of Persians for three days in one of history's most famous last stands.<ref>[[Wikipedia:Battle of Thermopylae|'''Wikipedia's''' article on Battle of Thermopylae]]</ref>
*A small force led by King [[Wikipedia:Leonidas I|Leonidas]] of [[Sparta]] blocked the only road through which the massive army of Xerxes I could pass. After three days of battle, a local resident named Ephialtes betrayed the Greeks by revealing a mountain path that led behind the Greek lines. Dismissing the rest of the army, King Leonidas stayed behind with 300 Spartans and 700 Thespian volunteers. The Persians succeeded in taking the pass but sustained heavy losses, extremely disproportionate to those of the Greeks.
*The fierce resistance of the Spartan-led army offered Athens invaluable time to prepare for a decisive naval battle that would determine the outcome of the war. The subsequent Greek victory at the Battle of Salamis left much of the Persian navy destroyed and Xerxes I was forced to retreat back to Asia, leaving his army in Greece under Mardonius, who met the Greeks in battle one last time. The Spartans assembled at full strength and led a pan-Greek army that defeated the Persians decisively at the Battle of Plataea, ending the Greco-Persian War and with it the expansion of the Persian Empire into Europe. This war was shown by [[Deja]] on the first day of [[SPARTAN-II|Spartan]] training.

*In April, '''2291''', a group of researchers headed by [[Tobias Shaw]] and [[Wallace Fujikawa]]<ref>'''[[Halo: Contact Harvest]]'''</ref> secretly developed the [[Shaw-Fujikawa Slipspace Drive]], a practical means of propelling spacecraft across vast interstellar distances. This new engine allowed ships to tunnel into "the Slipstream" (also called "[[Slipspace]]"). Slipspace is a domain with alternate physical laws, allowing faster-than-light travel without relativistic side effects. Faster-than-light travel is not instantaneous; "short" jumps routinely take up to two months, and "long" jumps can last six months or more. The SFTE generated a resonance field, which when coupled with the unusual physics of the Slipstream, allowed for dramatically shorter transit times between stars; however, scientists noted an odd "flexibility" to temporal flow while inside the Slipstream. Though no [[human]] scientist is sure why travel time between stars is not constant, many theorize that there are "eddies" or "currents" within the Slipstream. There is generally a five to ten percent variance in travel times between stars. This temporal inconsistency has given military tacticians and strategists fits-hampering many coordinated attacks.<ref>http://www.xbox.com/en-US/games/h/halo/storyline.htm</ref>
