Sangheili

"On the blood of our fathers, on the blood of our sons... We swore to uphold the Covenant!"

- Rtas 'Vadumee before the Battle of the Gas Mine.

The Sangheili (Latin Macto cognatus, meaning "I glorify my kin") are a saurian species of fierce, proud, strong, agile and intelligent warriors and innovative strategists. Sangheili are named after their home planet, Sanghelios. Known to humans as Elites, due to their adeptness and skill in military strategy, the Sangheili formed the military backbone of the Covenant for almost the entirety of its existence up until the Covenant civil war. They had a very strong rivalry with the Jiralhanae, which finally became open hatred during the Great Schism at the conclusion of the Human-Covenant War.

Originally a founding species of the unified conglomerate of races known as the Covenant, they later led the Covenant breakaway faction known as the Covenant separatists, who sided with the humans against their former allies, due to the fact that the Prophet of Truth and the Prophet of Mercy had ordered the genocide of the entire Sangheili race. This was established after the assassination of the Prophet of Regret at the hands of John-117. It was the Sangheili who were ultimately held responsible for the Prophet of Regret's death, and were seen as "unfit" to continue to guard the Prophets. The Prophets sought to achieve this through the use of the other Covenant races, primarily the Jiralhanae. The aftermath of the Great Schism formed the bedrock of the Covenant's ultimate collapse.

The Ark and reseeding
The Sangheili home world, Sanghelios, had at one point been visited by or had been in contact with the Forerunners. During the Forerunner-Flood war, the Librarian visited the planet to retrieve specimens of the Sangheili for preservation aboard Installation 00. After the firing of the Halo Array, they were returned to their home planet to begin re-building their culture.

Development of civilization and the Covenant
After being returned to their homeworld, the Sangheili discovered artifacts left by the Forerunners on their planet. The Sangheili revered the objects these "gods" had left, and considered tampering with them a heresy beyond any other. In 938 BCE they encountered the Reformist San 'Shyuum (who would later be known as "Prophets" by humans), a race who also worshiped the Forerunners as gods, but had utilized Forerunner technology for their own needs, believing the technology had been left behind by the Gods as gifts for their children. This sparked a war between the two races over how to treat the relics. Even though the Sangheili were much more physically imposing and numerous, they suffered extreme casualties under the sheer power of the San 'Shyuum's Dreadnought, a surviving Keyship, and by 876 BCE even the most devout had to admit their survival depended on the reconstitution of their own Forerunner technology. This, of course, led both sides to an agreement that ended with the decommissioning of the Forerunner Dreadnought and a shaky alliance that eventually expanded into the Covenant.

The San 'Shyuum helped assuage the Sangheili by informing them of the Great Journey: by seeking out the Holy Rings scattered throughout the galaxy and utilizing them, a Great Journey would begin. This Great Journey would transform believers into godlike beings, while providing salvation for their doomed existence of fighting with the Flood. The Sangheili then became the bodyguards of the physically less imposing Prophets, who would search the galaxy for the Halos. The Writ of Union was drawn up in 852 BCE in order to codify the Covenant. Its first canto clearly outlines the nature of the Covenant from the perspective of the Prophets.

Being one of the few races in the Covenant to achieve space-faring status without outside intervention, Sangheili interaction with the San 'Shyuum was initially strained due to memories of the recent war. However, the two sides later formed a prosperous relationship, eventually laying the foundation for the modern Covenant hegemony.

During their membership in the Covenant, the Sangheili were simply put, technological and societal equals of the San 'Shyuum. However, for a significant period, they found themselves as the dominant military muscle for the entire Covenant structure - hardly surprising given the warlike, feudal nature of their homeworld, Sanghelios. What was surprising was the cyclical stability this feudal society was able to offer. Technological and medical advancement prospered, and the intelligent, aggressive Sangheili were peerless until they encountered the San 'Shyuum. With exchange of goods and ideas, the Sangheili adapted to and eventually embraced the Covenant religion, grafting its tenets to their own belief system.

Human-Covenant War
When the Prophets declared war on a previously unknown species called "humans", the Sangheili followed their lead without question. After a period of time, however, even though the Prophets insisted that the humans were "unclean beings" that must be eliminated from the galaxy, many seasoned Sangheili veterans began to question the refusal of the Prophets to even consider accepting the humans into the Covenant. They seem to believe that humans, although physically weak, at least compared to themselves, are brave and even honorable. Certainly, most Sangheili believe that humans should be offered admittance to the Covenant. Some even believe that the humans are equal to them - a considerable step for a Sangheili, or any member of the Covenant to make. The Sangheili admired how willing and brave the humans were when fighting to survive against outright extinction, they even respected to a certain degree those few soldiers who were willing to stay behind and cover their comrades from a Covenant attack. A few Sangheili even had some degree of disrespect for the San 'Shyuum before the Great Schism.

The Great Schism


During the final months of the Human-Covenant War, the political shift caused by both the Prophet of Truth and Tartarus, the Chieftain of the Jiralhanae, started a slippery slope that ended in the dissolution of the Covenant between the Sangheili and the San 'Shyuum. Originally, the Jiralhanae were viewed as savagely aggressive and extremely goal-oriented, which the Sangheili viewed as a serious threat should the Brutes ever begin to desire political power. This fear became reality when the Honor Guards of the Prophets, originally an all-Sangheili class, was transformed into a duty of the Brutes. This was directly caused by the death of the Prophet of Regret at the hands of John-117, the human "Demon" known as the Master Chief, despite Regret's protection from his personal squad of Sangheili Honor Guardsman. Soon the Brutes found themselves in new positions of power, such as Field Masters, Ship Masters, and veritable replacements for the Sangheili. At the same time, during the Battle of Installation 05, Arbiter Thel 'Vadamee and Rtas 'Vadumee (both of which soon dropped the 'ee' suffix from their name to signify their abandonment of the Covenant) discovered the truth of the Halo rings from the Monitor 343 Guilty Spark and the deceit of the San 'Shyuum.

These events led the entire Sangheili species to secede from the Covenant, forming the Covenant Separatists. They were aided by a few of the member-races within the Covenant, such as many Unggoy and most Mgalekgolo, even though many apparently ended up siding with the Covenant Loyalists despite the Sangheili's efforts. The secession included a movement to destroy the treacherous Brutes and Prophets, and the destruction of the Flood at all costs, eventually resulting in the Sangheili's alliance with the humans, persuaded by the Arbiter's counsel.

It is known that this civil war stretched from the human homeworld, Earth, all the way back to Sanghelios as the Sangheili attempted to wrest their share of the hegemony away from their new-found enemies. The Jiralhanae stepped in to fill the military void in ever increasing numbers, sensing the vacuum and opportunity left by the departure of the Sangheili.

Fall of the Covenant Empire
Finally, after the Battle of Earth, the Sangheili and humans managed to stop and subsequently kill the Prophet of Truth, effectively dissolving the Covenant. However, the Sangheili and humans were coerced to deal with a more massive threat; the Flood. Finally, the Arbiter and the Master Chief, after activating the newly constructed replacement Halo ring, effectively ended the Flood threat forever.

After the Human-Covenant War ended, there has been speculation of competition between the UNSC and the Sangheili, when it came to examining Forerunner ruins and relics like the Portal. However, by March 2553, the Sangheili and humans remain friendly to one another as evidenced by the conversation between Thel 'Vadam and Lord Terrence Hood. All the Sangheili who fought in the Battle of Installation 00 agreed to depart Earth and return to their home planet, Sanghelios, to ensure its safety.

Following the destruction of the Covenant, Sangheili society plunged into crisis. They fractured into multiple infighting factions with varying ideas on how to run their society, despite their ongoing war with the Jiralhanae. This was largely due to the fact they had become reliant of the Prophets during the millennia of the Covenant's existence. As they regained their independence, they were forced to re-learn to manage their society on their own, without the direction of the Prophets or the manual labor provided by the other client races. Meanwhile, the UNSC, specifically the Office of Naval Intelligence, took advantage of this situation, attempting to keep the Sangheili splintered and disorganized with the intent of making sure they would not pose a threat to humanity again.

As the Great Schism went on, the Sangheili continued their fight against the Jiralhanae. This was proving largely unsuccessful and the Sangheili were accepting serious losses. Without the Covenant to provide them with ships, technology, and repairs, they slowly lost warships and technologies they couldn't repair or replace. After the San 'Shyuum went into hiding, the Sangheili began to prevail against the Jiralhanae, who in turn began to fight amongst themselves. Having abandoned the Covenant, the Sangheili were now in a state of mass confusion in regards to their religion, because even though the San 'Shyuum lied to them, they had still given them purpose for their actions. The Sangheili were still religiously devoted to the Forerunners and were attempting to uncover the meaning of their faith.

Description
Sangheili are at least 2.24 meters tall including helmet and armor, have two fingers and two thumbs on each hand which are much larger than human fingers and thumbs, which make the Sangheili look ungainly when wielding small human weapons such as the pistol. They look vaguely like lizards or theropods, except for their jaws. When wearing armor, they take on a shark-like look because of the "fins" on the sides of their helmets. Their jaws are made up of four separate mandibles attached to their face, a more insect-like trait.

The Sangheili are attributed for great strength and intelligence, and are praised for their bravery and honor. Sangheili warriors augment these natural abilities further through use of Energy Shields integrated into their armor. Depending upon rank and mission objective, they are commonly seen in battle with Plasma Rifles, Covenant Carbines, Needlers, Type-31 Rifle and sometimes, if they are higher ranked, Energy Swords. Sangheili employ coffin-like Orbital Insertion Pods as well as Phantom and Spirit Dropships for military transit purposes and rapid-response operations. Historically, Sangheili have followed the Covenant mentality of maintaining hatred towards humanity, believing them to be an affront to their religion and a challenge towards the Great Journey. However there are signs that this stance is being slowly abandoned as seen in the tentative alliance between the two enemies, forming the core allied faction at the end of Halo 2 and during Halo 3.

In Halo: Combat Evolved, upper ranks have a Forerunner symbol adorning their back. It is not known if the symbol varies from rank to rank. In Halo 3, Sangheili have Forerunner symbols on their arms and on the sides of their torso.

Anatomy and physiology
Sangheili are muscular and are at least as tall as a SPARTAN-II. Their jaws are quadruple-hinged, with an upper jaw and four mandible-like lips. With few exceptions, these mandibles are generally shown with six teeth each; many sources also depict an additional large fang on the tips of each mandible. Anywhere from eight to ten broader teeth have been observed mounted on the central jaw structure. In Halo Wars and Halo: Reach, the Sangheili are depicted with more numerous, more feral-looking teeth. In the Halo Legends short The Duel, the Sangheili Han, Fal 'Chavamee, and Roh, keep their mandibles closed, using only the front two joints of their lower mandibles to speak, giving them a more humanoid appearance. While it may not actually be canon to the Halo franchise, it is possible that the Sangheili don't usually use all four of their mandibles, except when breathing heavily; an example would be during combat situations, though this has yet to be confirmed. Sangheili smell with the use of two nostrils, each a little in front and below the eye socket. Given their predatory nature, a Sangheili's sense of smell is likely very developed. Their hands are tetradactyl, having four digits; two middle fingers, and two opposing thumbs on the outside for grasping. Their legs are digitigrade, with short upper and lower legs, and elongated tarsals, using the distal and intermediate phalanges to support their weight when walking. This arrangement possibly allows them to run very quickly and jump large distances, compared to ordinary humans and other Covenant races. Their superior agility may also be attributed to their homeworld's higher gravity; the additional strength required to move normally in a high-gravity environment would likely cause them to be more powerful in lower gravity situations. They also appear to have a double set of pectoral muscles, which contribute to their incredible strength.

Sangheili have a binary vascular system which circulates indigo-colored blood through their veins; the coloration is most likely caused by bimetallic hemoglobin, possibly cobalt-iron, whereas the crimson-blooded humans possess monometallic iron-based hemoglobin. Though there are many theories on the subject, the chemical formula(e) of Sangheili hemoglobin is still unknown. It is assumed that they breathe oxygen, as they can breathe the same atmosphere as humans without any trouble, and their homeworld has a nitrogen-oxygen atmosphere, similar to Earth's.

Male Sangheili have grayish-brown skin; the majority of Sangheili have either dark blue, black, or brown eyes, although there are a few exceptions. It has been theorized that some Sangheili seem to have dark eyes because they wear eye coverings, which provide their heads-up displays. This hypothesis comes largely from the Arbiter's appearance - when standing before the High Council in his armor, his eyes were dark, but after his armor was removed, his eyes became a much lighter brown -- and is also supported by the fact that in Halo: Combat Evolved, a Sangheili's eye color is always the same color as their armor. Sangheili have laterally-positioned eyes with slit-shaped pupils, large irises, and horizontal eyelids, though these traits can only be seen in Halo 3 - Sangheili in Halo 2 have all black eyes with no pupils except for the Arbiter, and in Halo: Combat Evolved they never blink.

Sangheili are oviparous, laying eggs rather than giving live birth, and incubate their recently-hatched young in pods resembling neutral-buoyancy gel tanks.

Intelligence
"Although Elites are naturally very intelligent, their culture's long dependence on a military-industrial schema has led to an emphasis on might over science. In some regards, the advent of the Covenant made this position easier-allowing the Elites to concentrate even more singularly on military endeavors, while Prophets took care of science and technology."

- 343 Guilty Spark in the Bestiarum The Sangheili are fairly intelligent and are able to demonstrate this in combat. Sangheili are normally on the move when fighting, constantly running and ducking, strafing and dodging when firing at the enemy. When presented with an obstacle, such as a Warthog driving at them, they will move out of the way, and if a vehicle stops, they will attempt to board it or disable it. It should be noted that not all Sangheili make use of cover because of their superior strength; these are the Sangheili who hold the ranks of either Zealot or Councilor. The Sangheili seem to employ complex strategy only if it either improves success in battle, allows them to inflict more casualties on their enemies or if it conforms to the Sangheilian code of honor. In ship-to-ship combat, despite having the advantage of long range weapon such as plasma torpedoes, the Sangheili prefer to maneuver in close in an attempt to board their opponent's vessel, most likely due to their honor code. These Sangheili charge their enemies with reckless aggression, regardless of any damage they sustain; only very seldom do they admit temporary defeat. They are quite capable of luring their enemies into traps by falling back into cover; as the enemy approaches, a Sangheili will spring from its position and land a massive melee hit on the unsuspecting opponent, and is especially even more dangerous if the hiding Sangheili is carrying an Energy Sword due to the weapon's lethal melee power.

It is clear the Sangheili are good military planners on a grander scale, renowned for their ferocity and decisive thinking. This is shown to be very true in space during ship-to-ship combat, even when horribly outnumbered; they could win the fight with only few losses against humans and Brutes. This shows them to have a greater degree of intelligence than Jiralhanae, even some human beings. Although the Sangheili had much more advanced ships than the humans did. An example of this is the Battle above Installation 00, when Truth's fleet outnumbered Sangheili forces three-to-one, yet the Sangheili prevailed with the assault carrier Shadow of Intent and a few other ships as well.

Although they are excellent strategists and on the whole an intelligent race, their code of honor often gets in the way of it; Elites for the most part have shown a preference for close combat with their foes, and the majority of their weaponry is suited for short-ranged fighting. The Energy Sword, being the most prized weapon of the Sangheili, is the strongest example of this. Swords are often carried and used as primary weapons on the battlefield by Sangheili, and although devastating in hand-to-hand combat, are useless at long range and make for highly visible targets. UNSC forces have been able to take advantage of this to decimate Covenant forces from outside their range while taking fewer casualties than the latter.

The Sangheili practices of commanders leading from the front and distinguishing leaders through colored armor has resulted in a very high attrition rate for Sangheili commanders. In many battles, Zealots have been killed early in the fighting (such as Noga 'Putumee), leaving their forces leaderless and uncoordinated. UNSC snipers have been specifically trained to pick out and eliminate high-ranking Sangheili, though this rarely happens. The Sangheili tradition of promotion through feats of arms on the battlefield has sometimes placed individuals of questionable tactical and strategic skill, such as Ripa 'Moramee, into high-ranking positions, purely because of their ability to kill their enemies personally (though Ripa 'Moramee became Arbiter because of a failed coup 'detat on his clan leader rather than the amount of casualties he inflicted on enemies). However, it should be noted that this isn't common and certain Sangheili such as Thel 'Vadam and Rtas 'Vadum are brilliant strategic-planners.

What the Sangheili lack in common sense due to their code of honor getting in the way, they make up for in their training, technology, and maneuverability in combat. On the other hand, the Elites' judgment of what is honorable or dishonorable has limited their flexibility in battle, meaning that they can be very rigid thinkers. However, the Sangheili can be quite strategically creative as long as those strategies conform to the their code of honor. Being wounded is considered a dishonor by the Sangheili, and it has been seen that most Sangheili go berserk upon having their blood spilled and charge straight at their enemies for revenge. Others, such as Jora 'Konaree, have chosen to kill themselves after being seriously wounded in battle. The preference of most Sangheili to die rather than live wounded has resulted in unnecessary casualties. Retreat is viewed as an even greater dishonor, and many Sangheili have doomed themselves to be killed rather than retreat, also resulting in unnecessary casualties. The UNSC (and the Brutes to a limited extent) have very frequently attempted to take advantage of how the Sangheili concept of honor gets in the way in order to lure them into traps. Examples of this include the Battle of Installation 05 on the Brutes part, Operation: FIRST STRIKE, Kurt-051's final actions in the Battle of Onyx, the Battle of Alpha Base, and Admiral Cole's last stand at Psi Serpentis.

Culture


The Sangheili consider most other species to be inferior to them, both culturally and in fighting skill; this thinking has caused Sangheili to treat other species cruelly and in an arrogant manner. This eventually led to the feud between the Sangheili and Jiralhanae and the attitude of superiority the former have, just proves that the two species are morally both as bad as each other. Although Sangheili are naturally very intelligent, their culture's long dependence on a military-industrial scheme has led to an emphasis on might over science. In some regards, the advent of the Covenant made this position easier-allowing the Sangheili to concentrate even more mono-manically on military endeavors, while Prophets took care of science and technology. Despite this, their adeptness at using and creating technology is evident. It is probable that they designed many of the Covenant's warship types themselves. They demonstrated their superiority at space combat in the battle with the Brutes over Installation 00.

Promotion in the Covenant military is by merit; a Covenant soldier must succeed to advance among the ranks. Success is often measured in scalps. A Zealot, for example, has personally slaughtered thousands of individuals to reach that status.

Raised from childhood to be warriors, other societal roles are treated as secondary endeavors or even hobbies, and are not honored at all. Elites are very skilled in most weapons such as plasma rifle and carbine, and hand-to-hand combat. One interesting example of this martial focus is that only aristocrats are allowed to wield swords and that sword-wielders are then no longer eligible for marriage; however, they may breed with any female they choose, married or otherwise, to ensure successful transmission of "swordsman" genes.

In many ways, the Sangheili are not dissimilar to humans. They communicate, are loyal to their superiors and comrades, become protective of their troops and become angry and vengeful if other Sangheili are killed. However unlike humans, they fear very little, taking great pride in an ancient, honor-laden code. Even when mortally wounded, the Sangheili still charge towards the enemy in a doomed last minute attack. Sangheili honor also dictates that they always be the first ones into a battle, and to never allow themselves to be captured alive. The more honorable captured Sangheili typically commit suicide while in prison to retain some measure of honor; often times when they are freed those who have not are executed anyway, as was the case with one of Thel Vadam's ancestors. However, escaping or staging an uprising is acceptable, by the same example.

Respect and honor
The Sangheili display respect and admiration for honorable fighters, whether they are allies of the Sangheili or not. It is not unusual for the Sangheili to have such an admiration for their adversaries. Sangheili respect and revere veterans and often follow their lead. Their history is rife with victorious combatants welcoming the defeated enemies' remaining forces into their own army, provided of course that they fought with honor. During the Unggoy Rebellion, the most tenacious of the Unggoy who survived the conflict were admitted for the first time into previously all-Sangheili forces, much to the Prophets' discontent. It is likely that survivors of this group of Unggoy were among the Unggoy supporting the Sangheili during the Great Schism, out of respect, and dislike of the Covenant.

The Sangheili code of honor appears quite similar to Japanese Bushido, sharing concepts such as skill in combat (with an emphasis on swordsmanship), loyalty to master and family/clan, and views on death. Both systems promote death in battle as being the most honorable and proper way to die. If a warrior is critically injured, incapacitated, or captured, the only acceptable recourse is to commit ritualistic suicide, ensuring one's honor is kept intact. This was of such import to Sangheili warriors that even if they were incapable of killing themselves, they requested the assistance of their fellow Sangheili in doing so.

Superstitions
Despite their martial nature, the Sangheili have reservations to the spilling of one's own blood. This is an extension of the belief that the blood of a warrior is his essence (honor); thus, to spill one's blood is to lose one's honor. As a result, in Sangheili culture, doctors are seen by many as the lowest members of society because they "..make [their] living slicing and causing another Sangheili to bleed without honor." This meant that the only 'honorable' way for a Sangheili to be injured or bleed out is from combat with the enemy. This belief also makes visiting a doctor very shameful for some Sangheili.

It is believed among the Sangheili that a weapon is only to be drawn if it is to be used, because a drawn weapon "demands blood."

Government
Sangheili government appears to be a feudal meritocracy, and is partially democratic, as elders of different clans rule different areas. The ruler of these areas, a Kaidon, is elected by a group of council elders that reside in that area. If a council elder believes that his vote was "ill advised" or "had second thoughts", it was considered a tradition for council elders to initiate some form of attack, such as sending assassins, against the Kaidon in order "...to test the true merit of [the] ruler's martial abilities." The belief was that "a Kaidon who could not defend himself was not a true leader." Should the attack fail, the responsible elder will be executed immediately, and his family will be killed. However, punishment for this form of heresy was usually flexible. As such, if the elder did something honorable, such as attack the Kaidon himself, or attempted to make a final stand against the Kaidon, then he would probably have managed to save his family from certain death, although they might still be banished.

Family
Family history and lineage are greatly valued, with each family having their own unique "battle poem" detailing the deeds and actions of its members during times of war.

While Sangheili males are sent into service as warriors and soldiers, female Sangheili hold considerable power in political matters, civil duties and trade. The most powerful females are also allowed to control bloodlines and choose their mates, and may sometimes have little regard for warriors.

Sangheili warriors form very close-knitted relationships, referring to their comrades as "brothers" and remaining intensely loyal to them. This loyalty is shown in the custom of grieving after the death of a fallen comrade, a ritual which includes prayer for the dead warrior.

Children
In some clans, Sangheili children are raised in "common rooms" to ensure that all start on an equal footing and progress in rank by merit of their abilities. Members of some Sangheili clans rarely know their true fathers, and are usually raised by a maternal uncle instead. This may be a method of preventing status from being inherited in order to force children to make their own way in the world so they actively work for and earn advancement. However, as some children's fathers were swordsmen who were granted the right to reproduce with any number of female Sangheili they desire, the use of a maternal uncle as a father-like figure may have also been used to allow children to be raised equally. Sangheili believe that copulation without regard for the bloodline is uncultured. A popular pastime for Sangheili children is to hunt small rat-like creatures that live on their homeworld.

Naming
The Sangheili place great value in their names, and it is considered both a privilege and an honor for only those proved worthy. The Sangheili generally consider humans to be nameless (one notable exception being the Spartans encountered in the battlefield, whom they exclusively refer to as "Demons"), and resent that the humans have assigned the label "Elite" to them (although they have been given many other names far more derogatory, such as squid-head, split lip, split face, etc). The word "Elite" is often transposed as an English translation of their own name in-game and in other media.

The surname of each individual comes from their lineage. Thel 'Vadam, for example, was from the Vadam lineage. Each lineage has its own state on Sanghelios, and each Sangheili from that state adopts the name of the lineage.

Sangheili names are constructed from a series of parts, each of them with a specific or special meaning. The first name is a given name that is attained at birth, which persists until adulthood. As they come of age, they earn the right to carry a badge name. This name is made up of three parts: an adjectival descriptor, such as "fast" or "deadly," a crèche or family name, and the "-ee" suffix, an honorific indicating that the Sangheili is a military participant. Since the Great Schism, most Sangheili in the rebellious faction have removed their name of the '-ee' suffix. Most Sangheili have names with this kind of construction. It appears that additional titles may be given to those of very high rank, such as Xytan 'Jar Wattinree. Since "Jar" is not a part of the standard Sangheili name, it may be assumed that it denotes Xytan's status as Imperial Admiral, although this has yet to be confirmed. There is only one other known instance of this naming strucure: Voro 'Mantakree, who was given the additional title "Nar" to denote his status as a Fleet Master. Apart from the "-ee" suffix, the suffix "-ai" denotes swordsmanship, as with Bero 'Kusovai and Toha 'Sumai.

Homeworld
Sanghelios is the homeworld of the Sangheili species with a population of 8.135 billion. Sanghelios is the fourth planet in a Triple Star System of stars Urs, Fied, and Joori. The planet has two Moons called Qikost and Suban. Many Forerunner artifacts exist on the planet, which are (or at least were) the topic of worship, as well as the cause of historical wars between the Sangheili and the San 'Shyuum before the formation of the Covenant. Sanghelios is divided into provinces, which are subdivided into states. Each state is owned by a lineage, and everyone born in that state adopts the lineage's name as a surname. Each state is controlled by a Kaidon, who is advised by Elders.

Rank structure
Sangheili are promoted based upon their skills, abilities, and the number of casualties they inflict upon their enemy. A high-ranking Sangheili may have personally slaughtered thousands of enemies throughout his military career. Higher-ranking Sangheili wear more complex armor, much like in the Jiralhanae rank system.

Other ranks and titles
In times of an extraordinary crisis, the High Council bestows the rank of the Arbiter on a single Sangheili. The most notable Arbiters are the ones of the Unggoy Rebellion, the Taming of the Lekgolo, Fal 'Chavamee, Ripa 'Moramee, and most notable of all, Thel 'Vadamee, the Arbiter who stopped the Covenant heretics on Threshold's Gas Mine and then aiding the UNSC and Covenant Separatists in the Great Schism. The armor of the Arbiter is an ancient version of the current Sangheili harness, which has primitive active camouflage that only last for a variably short period of time. The Prophets have also used the position of Arbiter to send those due to be executed unceremoniously on so-called "suicide missions" so that they can regain their lost honor and die a glorious death in battle.
 * Arbiter

The Councilors share power with the minor Prophets on the High Council. After the Changing of the Guard, the Councilors were taken to Installation 05, where most were murdered by the Jiralhanae. A number were saved by fellow Sangheili during the early stages of the Great Schism, some of whom assisted in the fight against Tartarus.
 * Councilor

Only one Councilor is known by name: Soha 'Rolamee. Based on this, Councilors must be required to submit to a certain degree of military participation, given 'Rolamee's '-ee' suffix.

The Supreme Commander appears to be the Covenant equivalent of the human "Commander-in-Chief". The only known Supreme Commander was Thel 'Vadamee, who commanded three fleets during the Fall of Reach, while serving as fleetmaster of his own Fleet of Particular Justice, which he took to Installation 04.
 * Supreme Commander

Kaidons are leaders of particular States on Sanghelios, and the heads of their lineages. They are advised and elected by a council of elders. They may also serve in the Covenant military, though Kaidon does not appear to be a military rank.
 * Kaidon

Oracle Masters are apparently advisors to the High Council and to the High Prophets, specializing in intelligence gathering and providing religious counsel to high-ranking Prophets and Sangheili Councilors.
 * Oracle Master

Aristocrats are important members of Sangheili society, allowed to wield energy swords. They are unable to marry but are allowed to mate with any female, married or unmarried, to "pass on the genes of sword fighting and the nobility." Aristocrats can hold nearly any military rank.
 * Aristocrat

Ossoona, a term that translates as "Eye of the Prophets", are Sangheili who are used as special-purpose espionage agents. They are not properly equipped for heavy combat, as they are intended for information gathering on enemy weapons and military data. One of the major items of information the Ossoona were tasked with discovering was the location of Earth. It is a temporary rank only granted to those who have attained at least the rank of Major, the reason being that a Minor's lack of experience could cause them to be very easily compromised or that they may abandon the mission outright in pursuit of personal glory. It is not given to Sangheili of higher rank because they are considered too valuable and would rather engage in combat. The only known Ossoona was Isna 'Nosolee.
 * Ossoona

The Ascetics are a special group of Sangheili devoted to ensuring stability and purity within their society. The Ascetic armor has been made to inflict a psychological fear by the use of special elements in the armor, such as the two "fins" protruding from the helmet and bright, glowing orange lenses.
 * Ascetics

The Sangheili Commando unit is a branch of the Special Warfare Group based upon pre-contact ground forces. Sangheili Commandos possess hardened communication gear and up-link capable equipment that an ordinary Sangheili wouldn't have access to. Their armor is streamlined for better maneuverability in close encounters. The armor is lightweight and advanced internal equipment increase the overall effectiveness of an individual Sangheili.
 * Commando

Prison guards, as their name suggests, provide security for Sangheili prisons such as Weeping Shadows of Sorrow.
 * Prison Guard

Weapons Masters are Sangheili engineers who maintain and improve equipment used by the Covenant.

Heretic rank structure
Sesa 'Refumee, the leader of the heretics, wore armor that was modified from a standard combat harnesses, featuring body pieces with modified shapes and designs in shades of red and upgraded with a Sangheili Ranger's thruster pack. This gave him a unique advantage in combat, but it was not enough for him to defeat Arbiter Thel 'Vadamee, who slew him during the Battle of the Gas Mine.
 * Leader

Heretic Majors served as the commanders of the heretic Unggoy and heretic Sangheili Minors. They wore gold-colored heretic armor and were equipped with Covenant carbines and Sentinel Beams. A select few wielded energy swords. While not so skilled in the energy swords use as Sangheili Honor Guardsmen, Councilors, Zealots, or Ultras, they were quite dangerous due to their crafty flanking maneuvering and teamwork with other heretics.
 * Heretic Major

Heretic Minors were the file leaders of the heretic Unggoy. They wore brown heretic armor and wielded Covenant carbines and, occasionally, Sentinel Beams. They had superb accuracy, far superior to normal Sangheili Minors. Many were skilled Banshee pilots who flew in pairs, supplementing their effectiveness.
 * Heretic Minor

Trivia

 * The dialogue spoken by the Sangheili of Halo: Combat Evolved was made by reversing and slowing sound clips of Sergeant Johnson. "Wort! Wort! Wort!" is the reversed phrase, "Go! Go! Go!". With the IWHBYD Skull turned on in Halo 3, they will occasionally say their trademark, "Wort! Wort! Wort!".
 * Jason Jones at first wanted the Sangheili to have tails, but Shi Kai Wang talked him out of it by arguing that the Sangheili would look too animalistic, as opposed to being an intelligent race. An additional point was that when the Sangheili sit, the only place their tails could go was folded between their legs, creating a seriously awkward appearance.
 * Sangheili culture is comparable to that of the ancient Spartans of humanity's past. Rank is achieved by success, and much of their lives revolve around war.
 * It is mentioned in Ghosts of Onyx that Sangheili would rather die with their weapons out of energy than pick up fully loaded human weapons, yet they show no shame when they obtain them in Halo 3 and Halo 2. They will sometimes even thank the player when handed a powerful human weapon such as the Rocket Launcher. This is likely because they are Covenant Separatists, and no longer view humans as heretics, nor their weapons 'unclean'.
 * Although the player is not able to dual wield in Halo: Reach, Elites are occasionally seen dual wielding Plasma Rifles.
 * In Halo: The Fall of Reach, a Sangheili is said to have green blood when it has been purple in all game appearances to date.
 * The Elites are the first Covenant species the player encounters in most of the Halo games: when you make your way to the bridge of the Pillar of Autumn in Halo: Combat Evolved, at the trial of the Thel 'Vadamee in Halo 2, and in the opening cut scene of Halo 3. In Halo Wars, they are seen in the first cutscene during a battle on Harvest fighting against UNSC Marines. In Halo: Reach a camouflaged Elite can be found at the beginning of the Winter Contingency, though only on Legendary or it will not appear.
 * There has been a running inconsistency in the franchise regarding when humans first encountered the Sangheili. According to Halo: The Fall of Reach, Elites had not been deployed to combat against the UNSC prior to the Fall of Reach when John-117 encountered one above Reach. However, this has been abandoned in newer sources, most of which depict Sangheili being active in the field for most of the Human-Covenant War. Finally, the project page for Halo: Reach confirms that Elites have been observed in the field since the First Battle of Harvest in 2525.
 * In Halo: Combat Evolved, the Sangheili have two different types of helmet appearances. One is the classical shark-like helmet with the pointed cone at the peak of the helmet. The second is slightly different with a wide, crest-like and curved upper piece on the helmet instead of the classical conical helmet.
 * An exclusive set of Sangheili Officer armor is included with the Limited and Legendary editions of Halo: Reach.
 * In Halo 3, Sangheili pupils turn to vertical slits upon death, whereas they are circular and centered when they are alive. This is because they have horizontal eye-lids, which can be seen when they blink, and this is simply their eyes closed while dead.
 * In Halo: Reach, the Sangheili HUD compass has Covenant markings instead of cardinal directions. Sangheili night vision is also purple, as opposed to the green used by Spartans. However, Sangheili night vision is only available in Firefight Versus, when playing as Elites. The Sangheili HUD also features a target tracking system.
 * Over the course of development for the game Halo Wars, the Sangheili character model used in the cinematics went through at least 2 revisions. The initial version seen in the announcement trailer was later revised, being far closer in size, proportion, and overall physiology to the portrayal of the species in Bungie's games than the version in the trailer.
