Creatures of the Covenant, the path is broad, and we shall walk it side by side.
— The Prophet of Truth[2]

The Covenant Empire, referred to as the Covenant, is a theocratic hegemony made up of many alien species and alliances that maintained control over a large portion of theOrion Arm in the Milky Way galaxy. The Covenant is a political, military, and religious affiliation. They waged agenocidal campaign against Humanity, until they were formally defeated due to many factors – the most crucial of which was an internal conflict. Whilst the Covenant’s leadership was either lost during the Flood infection of High Charity or during the Battle of Installation 00, the Covenant continues to exist even after the conclusion of the war.[3] A faction of Sangheili loyalists remains, known as the Covenant Remnant; this group is intensely hostile to humans, breaking the truce formed at the end of the initial war with the Covenant. They have been seen to field large numbers of warships, but their true power, and indeed the number of Covenant involved with their activities, is unknown.

It is also unknown in what capacity the other parts of the Covenant  to exist, or even if any other fragments of this once-great empire remain.




In 938 BC[1] the San ‘Shyuum Reformists entered a Sangheili-occupied system that led to first contact between the San’Shyuum and the Sangheili. The San ‘Shyuum, who came to Sangheilios in order to claim and study the rich abundance of Forerunner artifacts left behind,[4] soon found themselves sharing different ideologies of how such relics should be treated, which quickly developed into conflict between the San ‘Shyuum and the Sangheili.

The Sangheili believed that Forerunner relics were sacred and should not be touched, while the San ‘Shyuum Reformists believed that they should be studied and use them to make practical objects of their own design.[5] The highly militarized and brutal Sangheili attacked the San ‘Shyuum almost as soon as their differences became apparent,[6] and a war between the two species raged for an eighty-six year period of time.[1]

At the start of the war, the Sangheili had a numerical advantage in terms of ships and soldiers, and their strength and military tactics overwhelmed their enemy by a considerable factor. The knowledge gleaned from years of travel and the capabilities of their Forerunner Dreadnought, however, gave the San ‘Shyuum the advantage in ship-to-ship combat, the most common type of combat witnessed during the war.[6]

Eventually both species came to fear a very real threat: annihilation. The Sangheili who feared it through the San ‘Shyuum’s use of the Dreadnought and the San ‘Shyuum who came to admit that if the Sangheili were this dangerous, there might be other sentient life far more threatening, making their chances of survival in the galaxy slim.[6] The long and brutal war caused the Sangheili to violate their very beliefs, study and incorporate Forerunner technology into their own in order to avoid defeat[6] — their  of Forerunner technology eventually caused a stalemate in the war against the San ‘Shyuum,[6] although their Dreadnought proved far too effective and forced the Sangheili to surrender.[4]

In their , the Sangheili have great respect for a worthy adversary and after their surrender the San ‘Shyuum sought to broker a Covenant between the two races, thus the term “Covenant”; the alliance between the two species was formed in 852 BC with the signing of the Writ of Union, the treaty that ended the conflict and brought about peace between the two races.[1]


The species that make up the hegemony known as the Covenant come from different parts of the galaxy and take all kinds of physical forms. The Covenant is organized into a caste system with their religious leaders – the San ‘Shyuum or Prophets – at the top of the hierarchial pyramid.[7]

The Covenant society is a single hegemonistic culture. It is a culture that practices imperial geopolitical dominance through implied means of power as opposed to direct military force.[8][9] There are three Covenant castes that make up the unity: the Religious caste, the Warrior caste, and the Worker caste.


The two ruling species of the Covenant are the San ‘Shyuum and the Sangheili; though the San ‘Shyuum are generally believed to be “the voice of the Gods.”[8] The Covenant have ten echelons of government, the highest echelon being the Covenant High Council, who are responsible for holding legislative, executive, and judiciary powers. Composed of 200 members of Sangheili and San ‘Shyuum,[10][11] the High Council is ruled by the three San ‘Shyuum Hierarchs. These Hierarchs are the highest political and religious authority in the Covenant. For each new Age, three new Hierarchs are appointed; in order for them to usher in a new age and assume power, they must receive a blessing from the Oracle of High Charity.[11][12] This Oracle is a Forerunner Artificial intelligence found within the Dreadnought which sits at the centre of the capital. Until the events that led to the war against Humanity, the Oracle had not spoken for over a millennia, so the ascension of the Hierarchs is steeped with political bribes, blackmail and manipulation of the San ‘Shyuum Philologist.[12][13]

The High Council consists of San ‘Shyuum Councilors and Sangheili Councilors, who are extremely important to the Covenant society. They share the central theocratic and decision-making body of the Covenant. In addition to the High Council, there are three other Councils: the Council of Concordance, the Council of Deed and Doctrine and theCouncil of Masters. Below that numerous Ministries exist within the Covenant government, each of which fulfils a single, but important role within the Governmental body of the Covenant.

In truth however, the San ‘Shyuum and Sangheili have an uneasy coexistence, and political infighting is very common behind the scenes.

Religion and CultureEdit

Main article: Covenant religion

The Covenant culture and religion is based solely on the worship and reverence of the Forerunners. Long ago, the San ‘Shyuum managed to decipher portions of data stored on terminals aboard a Forerunner Dreadnought. Thanks to the Forerunners’ robust translation systems, they misunderstood the many subtle meanings of Forerunner glyphs.[8] The San ‘Shyuum incorrectly interpreted the activation of the Halo Array as a means of transcendence – a process they came to call the Great Journey. They did not understand that this activation had been designed to kill the Flood – or more precisely – to kill the Flood’s food, creating a galactic genocide. They simply thought that the Forerunners had disappeared and left other species of the galaxy to their fates.[8] Because of this, the Covenant often search and recover their artifacts and often have to turn to war to achieve their ends. In Covenant society, personal vendettas are not tolerated,[14] although many conflicts in the Covenant’s past have been sparked by vendettas.[15]

The Covenant uses commerce itself as a form of economy. As the Covenant’s cohesion is grounded in their beliefs of working for and sharing Forerunner technology, every member of the Covenant is given a form of employment[5] – a service to fulfill in exchange for goods and necessities. In the Covenant’s culture, service for salvation is the moral motivation for the entire population.[16] Despite this, there is discrimination within the Covenant, due to their hegemonic thinking. The lesser species are treated as second-hand citizens with absolutely no political or representative voice or power.

The Covenant are always eager to add new species to their faith (with the exception of humans),[17] so long as they pledge allegiance to the San ‘Shyuum as their supreme leaders and the Great Journey as their religion.[18] Enlisted races are in all essence enslaved by the Covenant, forced to live a completely different way of life and – if unlucky enough – have their entire culture and history erased. The races of the Covenant are held together by a common belief – the slave races are driven by the religion which they have been forced to accept. Most races are only kept for their varying skills to be exploited, rather than to be a part of a flourishing empire.


Main article: Covenant military

Like other civilizations, the Covenant maintains a permanent armed forces branch, used to enforce order, conduct atmospheric and space combat operations, and generally project the Covenant’s power onto others. Formerly led by the Elites prior to the Covenant Civil War, the Loyalist branches are now led by the Brutes. The military comprises the Covenant Navy, the Covenant Army and the Special Warfare Group containing the Special Operations Division(SpecOps). The abilities of the various component races are often exploited by the military to help push forward the ever-growing war machine of the Covenant.

Humans are the only species known that have started war against the Covenant and survived, unlike the Grunts (Unggoy) who almost immedietly surrendered and joined the Covenant. The human’s very existence is heresy to all Covenant branches, such as Insurrectionists modifying Plasma Rifles for utility and accuracy, seen in the riots of Charybdis IX. It has been questioned as to why humans were not allowed into the Covenant by several individuals, however it would be that humans were “survivors” of the Forerunner era which would cause the Covenant and its belief to collapse.


Many of the alien species conquered by the Covenant are conscripted into, or gradually become part of the alliance.[16] However, during the first contact with the humans, the Oracle on board the Forerunner Dreadnoughtrevealed to Truth and Regret that Humans are Reclaimers, as shown by its luminary. Since the entire Covenant was based on the belief that the Forerunners had transcended, Truth and Regret knew if any of the other races found out what the Oracle told them, the Covenant would cease to exist.

San ‘ShyuumEdit

Main article: San ‘Shyuum
Who would doubt the Prophets? What have they foretold that has not come to pass?
— The Prophet of Truth

The highest caste, the San ‘Shyuum, or “Prophets,” as Humans call them, lead the Covenant and exert complete control over all religious and political affairs. Though physically weak, Prophets wield power through absolute command of the Covenant and through scavengedForerunner technology, leaving the task of conquest to the Elites and the other races. Their higher understanding of the Forerunners gives them great ego and religious influence over the Covenant. The High Prophets are addressed as “Hierarchs”, “Noble Hierarchs”, “Holy Ones”, or “Exalted” by the other races of the Covenant.

Main article: 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 second highest caste; Sangheili, or Elites as Humans call them,[20] served as the military leaders of the Covenant before the Great Schism in 2552. While Prophets often had the final say, it was the Elites who organized military campaigns and naval engagements. They maintain the military structure of the Covenant and ensured the Prophets’ orders are followed, as well as their own. Sangheili consider the other client races to be below them in all ways. The Sangheili are the only known race permitted to build and operate starships within the Covenant, though the crews are almost always composed of a mix of races.[21] Sangheili are separated into ranks based on skill and experience. To advance in rank, Sangheili must honorably earn such advancements on the battlefield.[22] They were a major component of the Covenant and were the only caste able to maintain the military hierarchy as well as having a voice within the High Council before the Great Schism. An “ee” at the end of an Elite name, such as “‘Zamamee or ‘Vadumee”, signifies that that Elite is a part or was part of the Covenant military, although, after the Great Schism most, if not all, Elites removed the “ee” from their names to show that they had left the Covenant.

With my blessing, the Brutes now lead our fleets! They ask for your allegiance, and you shall give it
— The Prophet of Truth

Jiralhanae, known to Humans as Brutes,[20] They are one of the newer species to the Covenant and are the only race that has obtained very close to equal status to that of one of the founding “clients” of the Covenant pact, the Sangheili. They have an incredible natural resilience to damage due to their tough hides, which easily make up for their lack of energy shields, and use a number of weapons and vehicles based upon their pre-Covenant technology. This technology, though primitive compared to other Covenant weapons, is nonetheless extremely lethal, with most Brute-developed weapons having blades attached to them. In addition to their standard form of combat, Brutes will sometimes go “berserk” and try to kill anyone or anything in their path. This shows the aggressive nature of the Brute, and the little tolerance they have when they are cornered. Brutes have their own ranks going up to War Chieftains who usually wield plasma cannons,fuel rod guns, or Chieftains who usually wield gravity hammers. The Jiralhanae always work in packs of 3-8 when possible. They took over their role as personal bodyguards of the Prophets and also now make up most of the Covenant military.



Main article: Huragok
…They are some sort of biological supercomputers. Slaves, prisoners, I don’t know, but they don’t like the Covenant anymore than we do.
— Veronica Dare

Huragok, or Engineers are actually an artificial species created by the Forerunners. They will only converse with the Prophets or individuals who learn their language.[23] This indicates Engineers are very high in the caste system, however ONI believe them to be prisoners or slaves.[24] The Huragok perform the physical labor of excavating, and gathering data on Forerunner artifacts. In military terms, they are generally a non-militant race. However, at times in the Human-Covenant war they have been placed on the battlefield either as repair workers or suicide bombers. They have also displayed neutrality and even some allegiance to humans such as Lighter Than Some helping the citizens of Harvest escape and another Engineer repairing Ascendant Justice’s engines for the Master Chief and even a Needler for him to use in battle. Another example is one Huragok repairing and recovering the Human AI Superintendent and then assisting Captain Veronica Dare and Sergeant Major Avery Junior Johnsonin working out what the High Prophet of Truth was looking for in Africa. It was also revealed that they are equipped with a personal energy shield only when they are under duress. Additionally, these Huragok are also able to project an energy shield around its allies, or enhance shielding already present, if they are within its proximity.

They’re all scary and angry and they like to smash things…
— Bungie

Mgalekgolo, or Hunters as they are known by Humans,[20] are thought to be giant monsters, but they are actually an assemblage of worm-like entities called “Lekgolo” that create a communal, armor plated form. In this form, they are known as “Mgalekgolo”. They always fight and travel in pairs known as “Bond Brothers” which technically means that not all of the colonies of worms were able to fit within one set of armor, and are the strongest of the Covenant fighting units. They wield powerful assault cannons and a massive shield resistant to any small arms fire which may also be used as a melee weapon due to its sharp sides and the Hunters’ great strength. They are usually used as weapons platforms, and are only deployed on the battlefield when in need of a heavy force – they are used more like heavy duty equipment than soldiers. Their political and religious motivations are completely unknown.

HaloReach - DroneYanme’e.


Main article: Yanme’e
Drones aren’t brave; they’re just incapable of feeling fear.
—’s description of Drones.

These flying insect-like creatures, also known as Drones or Buggers by Humans, served almost exclusively as engineers, but were then replaced by the Huragok. This created a hatred towards the new, peaceful engineers by the Yanme’e that sometimes resulted in violence. Afterwards, the Yanme’e were used as aerial combatants against the UNSC, who were inexperienced at fighting airborne infantry. In combat, their weapons of choice were the Needler, which creates a super-combine explosion if enough projectiles are fired into the same target, and the Plasma Pistol. Their ability to fight on the wing, and their usual deployment in large groups, made them an excellent strategic weapon against ground-based opponents.

HaloReach - JackalKig-Yar Minor.


Main article: Kig-Yar
Jackals may be superior marksmen and they’re very sneaky, but that doesn’t make them excellent snipers — they’re a little too bloodthirsty for that.
— Anonymous UNSC Serviceman

Due to their superior senses, the Kig-Yar, or Jackals/Skirmishers as they are known by Humans,[20] are the scouts and marksmen of the Covenant military, they are the second lowest Covenant caste and are about 5’6″ tall and due to their lack of physical durability, they carry a portable energy shield generator during combat. Jackals are employed mainly as sharpshooters with their excellent vision and dexterity, and are also deployed to defend strategic areas. When a Jackal is under fire, it will cover its head with its hands and trot away to another position from which to fire. The first Human contact was between Staff Sergeants Johnson and Byrne on a Human freighter as Jackal pirates tried to board the ship. They have very strong dislike of the Unggoy because they are always trying to assert their superiority over them in the caste system of the Covenant. Once they poisoned a recreational narcotic that the Unggoy use which nearly caused them to become infertile. This caused one of the Unggoy unrests.

HReach - UnggoyAn Unggoy Minor.


Main article: Unggoy
When in doubt, flee.
— Unggoy Philosophy

Hailing from Balaho, Unggoy, known as Grunts among Humans,[20] are the most common and lowest-placed caste of the Covenant. The Unggoy were barely into their own Iron Age when the San’Shyuum discovered them. Classified as a “Tier 6” civilization by the Forerunner charts, the Unggoy were at a primitive point in their cultural development, the Unggoy had little choice but to accept entry into the Covenant hegemony, or otherwise risk extinction.[25] After their incorporation into the Covenant their entire history was erased[26] and they essentially became a slave race. Despite their notable cowardice and ineptitude, they are quite dangerous in large numbers, which was why an Arbiter was needed to quell the Grunt Rebellion. They breathe methane and thus must wear a large tank on their back full of the methane to survive on other planets. Relations between the Unggoy and the Kig-Yar are strained in the best of times.

Creatures Inhabiting Covenant WorldsEdit

  • Scrub grubs” are small creatures the equivalent of the rats found on Earth. They were first mentioned in Halo: Contact Harvest, while inhabiting a Jackal ship.
  • Zap-Jellies” are sea creatures that live on the Grunt home world, Balaho. They are possibly the equivalent to large jellyfish on Earth.
  • Thorn Beasts” are a food source for the Covenant, though only observed being eaten by Brutes. The only reference to the Thorn Beasts is in Halo: Contact Harvest, when the Brutes are first mentioned, and in Halo Wars, in at least one of the timeline periods. They were also included in the original Halo game being developed for Mac.
  • Mud wasps” are insects found on the Grunt home world of Balaho.
  • Shade Crabs” are crustaceans found on the Grunt home world of Balaho.
  • Helioskrills” are predators found on Sangheilios that imitate rocks to catch their prey.
  • Doarmirs” are furry animals found on Sangheilios, their pelts were used by early seafaring Sangheili as cloaks, the tradition is continued by modern Sangheili Shipmasters.

History of the CovenantEdit

Main article: History of the Covenant

The Covenant created their own means of connoting time, comprised of “Ages.” The Covenant’s history is broken up into multiple occurrences of seven types of Ages, each representing the predominant theme that occurred during those periods of time. These ages do not necessarily follow one another in order, nor are they equal in quantity. As an example, there were significantly more Ages of Conflictand Doubt than Reclamation. Each Age is further broken into what is called Cycles. A Cycle is the Covenant version of a day and it represents one artificial day on High Charity. A Cycle contains approximately 265 units, which if translated into human time is one hour of time on Earth.[27]

After the first Age of Abandonment, the San ‘Shyuum and Sangheili were able to evolve into space-faring race. The root of the First Age of Conflict was the theological question of whether Forerunner technology should be revered or exploited. The conclusion of that conflict mark the First Age of Reconciliation, followed by the First Age of Conversion, this marked the beginning expansion of the Covenant by bringing the Lekgolo into the Covenant, throughout these Ages new races were incorporated into the Covenant. In between these ages were what became known as the Ages of Doubt, these ages signified that no great discoveries were made, and members of the Covenant grappling with internecine conflict.[27]

During the 23rd Age of Doubt the Covenant encountered Humanity for the first time. This inevitable meeting would start a war that over time threw the entire foundation of the Covenant’s religion and political alliance into a gradual state of disarray.[28]

The First Age: Ignorance and Fear.

The Second Age: Rivalry and Bloodshed.

The Third Age: Humility and Brotherhood.

The Fourth Age: Wonder and Understanding.

The Fifth Age: Obedience and Freedom.

The Sixth Age: Faith and Patience.

The Seventh Age: Journey and Salvation.”
— Maccabeus and the Jiralhanae of the Rapid Conversion.[29]

A Covenant vessel discovers the location of the human colony world Harvest . The ships  Luminary detects thousands of Forerunner artifacts and an Oracle (ancilla) on the surface of the planet. The Kig-Yar planeed to take some of the treasures for themselves before reporting their discovery to the Hierarchs. They raided human freighters but unfortunately the humans already had a strike team to counteract what they believed was a growingInsurrectionist group. 

An Unggoy and his Huragok friend were able to escape and they informed the Minister of Fortitude and Vice Minister of Tranquility. The two utilize a Jiralhanea-controlled ship to help them capture the human planet. This starts the powerful alliance between the two species. 

The Jiralhanae travel to Harvest and their Luminary detects thousands of Forerunner artifacts as well. They land twoSpirit dropships to make contact with the humans. The two human A.I.’s attempt to peacefully communicate with the Jiralhanae. However the peace broke when an Unggoy opens fire on a Colonial Militiaman. The Battle of Harvestbegins. 

The two young Ministers seek out to talk with the long dormant ancilla that rested in the Forerunner Dreadnought . The ancilla, 05-032 Mendicant Bias, explains to the two San’Shyuum that they have been misreading their findings. What the Kig-Yar detected on the Luminary weren’t artifacts, they  were actually detecting the humans on Harvest, which are actually called Reclaimers by the ancilla. Mendicant attempts to power up the Dreadnought to find the humans and take them to the Ark where they will be able to fire the Halo array, an act which will destroy High Charity. The two San ‘Shyuum decide to keep all this a secret from the Covenant, realizing that living Forerunners will destroy the entire foundation of the Covenant. The Lekgolo which swarmed the Dreadnought disconnected it in order to prevent the ancilla from completing his tasks. 

The Jiralhanae begin to glass Harvest. The two San ‘Shyuum overthrow the current Hierarchs and rise to power as the High Prophet of Truth and Regret. They declare a genocidal war on the humans to prevent any of the Covenant from ever discovering the humans true place as the Forerunners heirs and thus beginning the Human-Covenant war.  

After about twenty five years of war, the Covenant discovered the location of the human fortress world, Reach; its faith was the same as Harvest, but this time the human ship Pillar of Autumn managed to escape and Supreme Commander Thel ‘Vadamee ordered his ships to follow it into slipspace. The human ship led them to the location ofInstallation 04  . The humans landed on the surface and the Covenant forces followed to kill them all before they cause any damage to the ring. However, a Covenant archaelogical team discovered something buried deep within the ruins of Halo’s swamps—the Flood . Soon after, it spread every where, the plague was uncontainable. The Forerunner Sentinels and an ancilla, 343 Guilty Spark ,  helped the Reclaimers complete their tasks into activating the Halo ring to stop the Flood from spreading to other parts of the galaxy. But the humans found out that activating the Halo would wipe out all sentient life in the galaxy, so instead they destroy the ring. 

The Supreme Commander was called before the High Council to answer for his failures. The loss of the Forerunner relic angered the council and that of the entire Covenant. ‘Vadamee was stripped of his rank, title, name, and honor and branded a heretic. In front of the entire Covenant, he was given the Mark of Shame , and was then sentenced to be hung by his entrails and have his corpse be paraded through the city as an example to the others.  

The Prophet of Truth and Prophet of Regret intervened and instead offered ‘Vadamee the chance to become the newArbiter . While they prepared to get the heretic back into battle, The Prophet of Regret learned the location of Earth as the location the Portal , leading to the Ark .  However, Regret did not realize that Earth was actually the human home world. So he unknowingly led his small fleet into Earth‘s orbital defenses. 

Regrets fleet was unable to fend off the human defenses so he escaped to the newly discovered,Installation 05 . Truth learned about Regrets attack and immediately sent a fleet of Jiralhanae controlled ships to reinforce the attack.

The UNSC followed Regret to Installation 05 and were able to corner him. Regret then called out for help and the entire Covenant City, High Charity, jumped to that location. However, they were too late; the Demon managed to pass by Covenant defenses and assassinated the prophet.

Truth took advantage of his death as a way to convince the High Council to replace the Sangheili with Jiralhanae as the new protectors. Truth then ordered his forces to eliminate all Sangheili ships, initiating the Great Schism .  

During the final years of the war against humanity the remaining Prophets, led by the High Prophet of Truth, used the assassination of the Prophet of Regret at the hands of the Demon to replace the Elites with Brutes as their protectors. However, this political maneuvering enraged the Sangheili, who found their replacement as the Covenant’s military leaders to be in defiance of the Writ of Union and threatened to resign in protest. This act of defiance further convinced the High Prophets that the Sangheili could no longer be trusted to execute their orders without question.

Truth gave command of the Covenant Fleets to the Jiralhanae, a position previously held by the Sangheili.  . Once there were enough and an ample amount of Jiralhanae in place, Truth secretly ordered the Jiralhanae to commit a mass genocide on the Sangheili. With this act disguised and incognito as a Brute insurrection, the Jiralhanae replaced the Sangheili within the society of the Covenant. The Sangheili revolted, enlisting the help of some of their following Mgalekgolo and Unggoy, birthing a destructive civil war within High Charity itself and on the surrounding Covenant fleet. This event was known as the Great Schism

Early into the Great Schism, most of the Sangheili Councilors were assassinated by the Jiralhanae at the will of the Prophets, mainly the Prophet of Truth. When the Sangheili learned the truth about the Halos, it changed the war significantly; the Sangheili decided to ally with Humanity in the struggle. Instead of a Great Journey, the Gravemind’s revelation regarding the super weapon contradicted the entire Covenant’s belief system. 

While the civil war spread all over High Charity, the Flood had started to invade it.

Though the Prophet of Truth was eventually killed in the hands of the Arbiter, and most of the Loyalist’s known fleet was destroyed by the Sangheili fleet above the Ark, the Covenant still exists in some force, though in a weakened state, forced to rebuild after the war.[3] Rtas ‘Vadum expressed concern that the Sangheili homeworld, Sanghelios, may have still been endangered by the Covenant, and considering the sheer size of the former Covenant it is unlikely that the entirety of the Loyalists were present at Earth. Exactly who or what remains in charge of their political and military leadership is also unknown as the San’Shyuum population is only within the thousands and is near extinction.[30] They have not been sighted by the Sangheili since 2553.[31]

The devout and stubborn Jiralhanae continued their war with the Sangheili, and rogue clans continue to fight amongst themselves. Without the technical expertise of the San ‘Shyuum, the infrastructure of both races is on the verse of collapse.


Covenant technology is repeatedly referred to as more imitative rather than innovative.[32] Their technology is based largely on mimicry and reverse-engineering of the leftover Forerunner artifacts they have discovered than the Humans’. While Covenant technology is far more advanced than human technology, the Covenant seem to be ignorant of how precise or powerful their technology can actually be.[33]

While Humans are capable of learning and often improving on new technology, Covenant advances are significantly slower. This is, perhaps, the Covenant’s most serious disadvantage. Their technology is limited by this almost parasitic reliance on reversed-engineered Forerunner technology. In Covenant culture there are religious taboos that prevent them from fully exploring what the Forerunners employed to create that technology.[34]

Like Humans, Covenant ships can enter slipstream space and travel faster than light. However, the Covenant equivalent of the Shaw-Fujikawa Engine is far more efficient and reliable. Covenant vessels do not suffer the “temporal fluidity” of the slipstream to such a degree as Human vessels. As a result, Covenant battle groups are much more efficient when acting as a coordinated group, and can strike more quickly and decisively.[34]

Covenant starships use Repulsor Engines for propulsion in space, rather than traditional reaction drives used by the UNSC.[35] Covenant drive systems seem to be propelled by an unusual combination of gravity “waves” and some form of highly reactive plasma displacement, but the actual means and method of propulsion is currently beyond human understanding.[34]

Only two Covenant A.I. have ever been encountered. One was a rampant AI that was stationed aboard theAscendant Justice and destroyed by Cortana,[36] while the other was the Seeker, sent to infiltrate UNSC systems and alert the Covenant to the location of Earth. However, Cortana’s copy references several A.I.’s being present in the Unyielding Hierophant system when the Spartans infiltrate the base.[37]

Covenant architecture is known for its curved, organic and sophisticated looking style, likely for the aesthetic tastes of the higher-ranked castes. Constructed of distinctive purple or white metal, these colors are the main focus of Covenant design and distributed throughout their starships, and weapons. The metal they use is unknown to theUNSC but is very strong and resilient.


Most of the Covenant arsenal is plasma-based Directed Energy Weapons, however the Covenant are known to utilize Pulse LasersParticle beam weapons, as well as Antimatter and even chemical crystal-based weapons.

Plasma weapons are more rugged and far more effective than laser based weapons. They use a power cell to provide power to the internal components- most importantly a high energy current at the muzzle end of the weapon- to complete the cycling, ignition and release operation of the weapon. Plasma weapons use Hydrogen Fluoride as a source of fuel-[38] this fuel is flash boiled and contained within a magnetic field until it turns from a cool liquid to superheated ionized gas.

Covenant plasma weapons are effective but crude for their technology. As such, they are prone to overheating, a weakness among the weapon class. Weapon designs compensate for this, although they render weapons inoperable as the excess heat is dissipated. Once the energy of the plasma weapon is depleted, it must be recharged, or discarded.

The Covenant are also known to employ ammunition based weapons, the most common of these being crystal based weapons. These weapons appear to use some type of chemical that reacts to environments and forms a hard razor sharp crystal[39] that when fired, homes in on organic material and detonates when either embedded into an object or travels too far away from the weapon itself. These types of weapons are very dangerous because of their homing ability- one of the few “fire and forget” armaments on an infantry-portable level. With the introduction of the Jiralhanae as a major military caste within the Covenant, their weapons have found limited to widespread use.Jiralhanae weaponry typically utilizes crude projectile-like metal spikes in place of plasma, as well as explosive grenade-like launchers. Often, these weapons are outfitted with some form of sharp blade, spike or other implement as a sort of bayonet analog. On the whole, they are more primitive, brutal weapons than other Covenant counterparts – fitting, considering the nature of their creators.

The Covenant are also known to employ melee weapons in addition to their already fearsome arsenal. The most well known, is the energy sword, used solely by the Sangheili. Creating a solid blade of superheated plasma, it has both ceremonial and martial value to the Sangheili warriors, and its possession is closely monitored. Secondly is theJiralhanae Gravity Hammer, which seems to be the cultural analog to the sword. But rather than using a blade of plasma, it can generate a gravitational field, doing tremendous damage to anything in a close radius.


Covenant vehicles use advanced anti-gravity technology for propulsion, and are well armored and well armed. Though often faster than their UNSC counterparts, Covenant vehicles are more unstable over uneven terrain where the sudden changes affects its handling. All Covenant vehicles are made from a purple or dark blue type of metal, said to be much more advanced than any alloy known to Humans, and all Covenant vehicles are nicknamed after some kind of supernatural entity by the UNSC, except for Scarabs and Locusts. Recently, Brute vehicles and technology have been incorporated into the Covenant’s arsenal. Though more primitive, they serve the Brutes’ need for power. Brute vehicles are not named after spiritual entities, and rather than being a series of Covenant vehicles are regarded as native Jiralhanae technology.


Although rare in usage, medical equipment does exist in the Covenant. An Automated Surgery Suite is, as the name states, an automated medical room found on Covenant capital ships. Besides this, the Magnetic Splint is another piece of Covenant medical equipment. The splint, when attached, makes that particular part of the body immobile.[40]

    It frustrated him that no matter how much power he attained, he would never have the power to remove her hurt.  The one thing he would give anything for and it was the one thing completely and forever out of reach.  He sighed. 

    He nodded at her words.  He knew it would take time for her to heal from this wound.  He didn’t know how long because he had no experience but he’d stand by her no matter how much time it took.  He smiled softly and wiped the bubbles from his nose, planting them on hers with a crooked grin and peck on the lips.  “One step at a time, love.  Let’s worry about the divination tonight and go from there.”  He casually scooped up a swath of bubbles and fashioned a sparkling headband upon her obsidian hair.  “If Edward is not your father then the contract is void and who purchased your soul is of no consequence, nor are his feelings on the matter.  I would prefer you focus on harboring your strength for the ritual tonight.  Not that it’s going to tax you overly much, but the emotional strain could be severe, given your reaction thus far.”  He sat back and tilted his head back and forth, admiring his bubble headband, and then meeting her eyes with a sad smile.  “Let’s just take it slow.  Too much information isn’t helpful.”

    I know, I was a bit too tired to do at the time of doing it
