The '''Covenant''', also referred to as the '''Covenant Empire'''<ref name="xytan">'''Halo: Ghosts of Onyx''', ''page 239''</ref><ref>'''Halo: First Strike''', ''page 269'' (2003 edition); ''page 323'' (2010 edition)</ref> or '''Covenant Hegemony''',<ref>'''Halo: First Strike''', ''page 338'' (2003 edition); ''page 405'' (2010 edition)</ref> was a religious hegemony of multiple alien species that controlled a large portion of the [[Orion Arm]] in the [[Milky Way|Milky Way Galaxy]]. Originally a mutual alliance between the [[Reformists|San'Shyuum]] and the [[Council of City States|Sangheili]], the Covenant expanded to include at least six other species united in the worship of the [[Forerunner]]s and the [[Halo Array]].

They waged a [[Human-Covenant War|genocidal campaign]] against [[human]]ity until they were defeated in [[2552#December|December 2552]]. Despite being one of the most powerful military forces in the known Milky Way galaxy at the time, [[Great Schism|internal conflict]] combined with stubborn human resistance were formidable enough to shatter the bonds that held the empire together. While the Covenant Empire ended either during the [[Flood]] [[Fall of High Charity|infection]] of [[High Charity]] or during the [[Battle of Installation 00]], a number of [[Covenant remnants|remnant factions]], some of which maintain many of the ideals of the Covenant's religion as well as many of its former subject species, continue to exist after the conclusion of the war.<ref name="h4guide">[http://www.halowaypoint.com/en-US/halo4guide ''Halo 4 Interactive Guide'']</ref><ref name="H3 Assem">'''[[Halo 3]]''', ''[[Assembly (level)|Assembly]] description''</ref>

The Covenant created its own means of connoting time, comprised of "Ages." The Covenant's history is broken up into multiple occurrences of [[seven]] types of Age, 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 Conflict and Doubt than Reclamation. Each Age is further broken into what is called [[cycle]]s. A cycle is the Covenant version of a day and it represents one artificial day on [[High Charity]]. A cycle contains approximately 265 [[unit]]s, which if translated into human time is roughly one hour of time on Earth.<ref name="ency31">'''[[Halo Encyclopedia]]''' ''page 31''</ref>

===Foundation===
{{Main|War of Beginnings}}
[[File:HM-HighCharityBC.png‎|300px|right|thumb|The construction of ''High Charity''.]]
At some point before the San'Shyuum encountered the Sangheili, the [[Huragok]] were found by the San'Shyuum in various [[M-series facility|M-series facilities]].<ref name="best">'''Halo 3''', ''[[Bestiarum]]''</ref> In [[938 BCE]],<ref name="Ency1"/> the San'Shyuum [[Reformists]], aboard the [[Forerunner Dreadnought]] and the planetoid that would come to be known as High Charity, entered a Sangheili-occupied system that led to first contact between the two alien species. The San'Shyuum, who came to Sanghelios in order to claim and study the rich abundance of Forerunner artifacts left behind,<ref name="Ency114">'''[[Halo Encyclopedia]]''' ''page 114''</ref> soon found themselves sharing different ideologies of how such relics should be treated, which quickly devolved 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.<ref name="harv146">'''[[Halo: Contact Harvest]]''' ''page 146''</ref> The highly militarized Sangheili attacked the San'Shyuum almost as soon as their differences became apparent,<ref name="contact">'''[[Halo: Contact Harvest]]''' ''page 147''</ref> and a war between the two species raged for eighty six years.<ref name="Ency1"/>

At the start of the war, the Sangheili had a numerical advantage in terms of ships and soldiers. Their strength and military tactics were without peer. However the San'Shyuum's technology, gleaned from years of travel and study of their Forerunner Dreadnought, gave them the advantage in ship-to-ship combat. This proved to be the most common type of combat witnessed during the war.<ref name="contact"/>

Eventually both species came to fear a very real threat: annihilation. The Sangheili feared it through the San'Shyuum's use of their unstoppable Dreadnought; and the San'Shyuum came to admit that if the Sangheili were this dangerous, there might be other forms of sentient life far more threatening to their race.<ref name="contact"/> The long and brutal war caused the Sangheili to violate their religious beliefs, studying and incorporating Forerunner technology in order to avoid defeat.<ref name="contact"/> This incorporation of Forerunner technology eventually caused a stalemate in the war against the San'Shyuum,<ref name="contact"/> however their Dreadnought remained unstoppable. Faced with this bitter reality, the Sangheili surrendered.<ref name="Ency114"/>

With a proud tradition as warriors, the Sangheili held great respect for a worthy adversary, and after their surrender, the San'Shyuum sought to seek a burgeoning Covenant of the two races. In 852 BCE a tentative truce was worked out between the two species through the Sangheili leader, [[Pelahsar the Strident]], and the San'Shyuum [[Breaking Shadow]]. The two agreed to forgive the past crimes of their species and began efforts towards an alliance.<ref>'''[[Halo Mythos]]''', ''page 39''</ref> This eventually came about with the signing of the [[Writ of Union]], a treaty that ended the conflict and brought about peace between the two factions.<ref name="Ency1"/>

===Contact and conversion===
{{Quote|Most of those we encountered in our search were compelled to join our Union. To take part in a movement that promised freedom for allegiance, salvation for service!|The [[Prophet of Regret]]<ref>'''Halo 2''', campaign level ''[[Regret (level)|Regret]]''</ref>}}
[[File:H2A Terminals - First Hunters.jpg|thumb|right|250px|An [[Unidentified Arbiter (Taming of the Lekgolo)|Arbiter]] faces the [[Mgalekgolo]] in the [[Taming of the Lekgolo]], prior to their successful incorporation into the Covenant.]]
The conclusion of the conflict marked the First Age of Reconciliation, followed by the First Age of Conversion. This period was exemplified by the Covenant's expansion throughout the galaxy. In [[784 BCE]], the [[Lekgolo]] were encountered by the Covenant on [[Rentus]], a [[natural satellite]] of the Lekgolo homeworld of [[Te]].<ref>[https://www.halowaypoint.com/en-us/forums/db05ce78845f4120b062c50816008e5d/topics/catalog-interaction/4c3e1c6f-6519-4ee0-83a4-4bac13bf07a3/posts?page=74#post732 '''Halo Waypoint''': ''Catalog Interaction'' (post 2988575)]</ref> Upon the discovery that many of the Lekgolo worm colonies had literally devoured Forerunner artifacts and installations, [[Taming of the Lekgolo|a large-scale military conflict]] began. The Lekgolo initially proved difficult to defeat because of their ability to combine into the powerful [[Mgalekgolo]], however due in part to their superior spaceship technology the Covenant was able to ally with the useful Lekgolo and the species was indoctrinated into the hegemony.<ref>'''Halo Encyclopedia''', ''page 114''</ref><ref>'''Halo: Contact Harvest''', ''pages 269-271''</ref> In the year [[1112]], the Covenant discovered the [[Yanme'e]], an insectoid race with an interplanetary civilization. First contact was violent as both sides took heavy casualties. However, it was the Covenant who fared worse in these battles. Ultimately, the San'Shyuum discovered a way to communicate with the Yanme'e, and subsequently incorporated them into the Covenant by way of a treaty.<ref>'''Halo Encyclopedia''', ''pages 148-149''</ref>

[[File:H2A Terminals - Unggoy join Covenant.jpg|thumb|250px|left|Unggoy join the Covenant.]]
In [[1342]], the Covenant arrived in the [[Y'Deio system]] and encountered the [[Kig-Yar]]. Both Kig-Yar [[piracy|pirate]]s and [[Eayn]]'s militia joined forces in an attempt to fend off the Covenant military juggernaut. The war between the Covenant and Kig-Yar forces culminated in sieges of redoubts on the [[asteroid]]s surrounding their world,<ref>'''Halo Encyclopedia''', ''page 155''</ref> however the asteroids proved to be beneficial to the Kig-Yar. It was difficult for the larger Covenant ships to maneuver through Y'Deio's abnormally dense asteroid belt, while Kig-Yar forces could use the asteroids for hiding.<ref>'''Halo: The Cole Protocol''', ''page 157''</ref> Eventually, peace was reached between the Kig-Yar and Covenant. The Kig-Yar joined the Covenant, essentially as mercenaries, and earned commissions from the [[Ministry of Tranquility]] to engage in the services of the Covenant.<ref>'''Halo Encyclopedia''', ''page 121''</ref> The [[Unggoy]] were easily inducted into the Covenant as a labourer race in [[2142]]. In [[2462]], the [[Unggoy Rebellion]] began after the [[Ministry of Concert]] refused to punish Kig-Yar [[shipmaster]]s that were rendering Unggoy populations infertile as petty revenge for the displacement of Kig-Yar nests. The Unggoy proved to be vicious, determined and competent fighters and an Arbiter was ultimately needed to quell the rebellion. This Arbiter ordered the glassing of [[Balaho]], and in response the rebellion ended before much damage could be done, leaving the planet's surface intact for the most part. The Sangheili integrated the Unggoy into formerly Sangheili-only units and armed them with Covenant weaponry.<ref>'''Halo: Contact Harvest''', ''pages 150-152''</ref> The [[Jiralhanae]] were fighting a civil war on [[Doisac|their homeworld]] when they were discovered in [[2492]]. While some gladly joined the Covenant, others were unwilling at first. Nonetheless, they were quickly defeated and absorbed into the Covenant.<ref>'''Halo Encyclopedia''', ''page 115''</ref> In between the Ages of Conversion and Ages of Doubt, members of the Covenant grappled with internecine conflict.<ref name="ency31"/>

===War with humanity===
{{Main|Human-Covenant War}}
{{Quote|Your destruction is the will of the Gods... and we are their instrument.|The Covenant's first transmission to humanity, after the [[glassing]] of [[Harvest]].<ref>'''Halo: The Fall of Reach''', ''pages 96-98''</ref>}}
[[File:Doomed.jpg|left|thumb|250px|A battle between Sangheili and Spartans.]]
During the 23rd Age of Doubt, the Covenant [[First Battle of Harvest|encountered]] humanity for the first time on the planet [[Harvest]]. While many within the Covenant's leadership felt that this new race would make a welcome addition to the hegemony, the newly-appointed [[Hierarchs]] of the Covenant—[[Prophet of Truth|Truth]], [[Prophet of Mercy|Mercy]], and [[Prophet of Regret|Regret]]—had other plans. The Hierarchs were aware of humanity's status as the Forerunners' chosen inheritors, and knew that revealing this information to the Covenant would lead to the Covenant falling into chaos.<ref>'''Halo: Contact Harvest''', ''page 275''</ref> Greater than the cultural significance of the invalidation of the Great Journey, the leading San'Shyuum knew the truth about the Forerunners would lead to the loss of their personal power.<ref>'''Halo: Contact Harvest''', ''page 385''</ref> As a result, spurred on by a violent incident following the first human-Covenant contact, the Hierarchs declared humanity an affront to the gods and demanded that their entire species was to be exterminated. This decision would spark a war that ultimately would crumble the very foundation of the Covenant's religious and political alliances.<ref>'''Halo: Contact Harvest''' ''page 143''</ref> 

[[File:Origins ii Human-CovenantWar.jpg|thumb|right|250px|An invading Covenant fleet prepares its assault of a human colony.]]
The Covenant began a genocidal campaign against humanity, seeking out their worlds one by one and wiping them clean of all life. If the colony was especially important, they would scorch the planet's entire surface and mark it with a glyph of their religion, in a process known as [[glassing]]. The [[United Nations Space Command]] was able to slow the Covenant's progress through the [[Cole Protocol]], and by launching major offensive strikes at key military locations, as such with [[Operation: TORPEDO]], albeit with great sacrifices. With the execution of the Cole Protocol, the UNSC also managed to prevent the Covenant from locating the human homeworld, Earth, and other important [[Inner Colonies]] for over twenty years.

After decades of struggle, some Sangheili within the Covenant began to question why humanity was not offered a chance to join the Covenant as other races had.<ref name="convo">'''Halo 2''', ''[[Conversations from the Universe]]''</ref> Despite their losses, humanity proved a determined and brave enemy. They were especially troubled by their soldiers called [[Spartan]]s, who were more than a match for them in battles and often killed thousands of Covenant by themselves.<ref>'''Halo: Ghosts of Onyx''', ''page 349''</ref> While these idle heresies did not halt the Covenant's military progress, doubt began to surface as to the wisdom of the Prophets' ultimate goals; a doubt that was carefully observed by the spies of the Hierarchs.<ref name="convo"/> Notably, a major break-off faction known as the [[Banished]] was created by [[Jiralhanae Chieftain]] [[Atriox]] as a result of his disgruntlement with the Prophets' rule, and proceeded to persistently raid Covenant supplies for years while the Human-Covenant War raged on.<ref>'''Halo Wars 2''', campaign level ''[[A New Enemy]]''</ref>

After the massive, one month-long battle with heavy casualties for both sides, the Covenant delivered a serious blow to the UNSC as they suffered crippling military losses in a campaign known as the [[Fall of Reach]], and also, the [[Battle of Tribute]].<ref>'''Halo: The Fall of Reach''', ''page 320'' (2001 edition)</ref><ref>'''[[Halo 3: ODST]]''', ''Dutch's biography''</ref> After the UNSC stronghold [[Reach]] fell to the Covenant, they made a discovery of tremendous significance: a single UNSC vessel, the [[UNSC Pillar of Autumn|''Pillar of Autumn'']], had made a supposedly blind jump away from the battle, inadvertently leading the [[Fleet of Particular Justice|pursuing Covenant fleet]] to the location of [[Installation 04|one]] of the seven Halo rings.<ref>'''[[Halo: Combat Evolved]]''', campaign level ''[[The Pillar of Autumn (Halo: Combat Evolved level)|The Pillar of Autumn]]''</ref> The Covenant's celebration following the discovery of this prized relic was short-lived, however, as after landing on the ring Covenant soldiers accidentally released the dormant [[Flood]]. A small group of UNSC forces—among them the fearsome, enigmatic soldier known to Covenant forces as "[[John-117|the Demon]]"—managed to destroy the ring by detonating the ''Pillar of Autumn'''s [[fusion drive|fusion engines]].<ref>'''Halo: Combat Evolved''', campaign level ''[[The Maw]]''</ref> [[Thel 'Vadam]]ee, the [[Supreme Commander]] of the fleet present at Halo, was branded a heretic for his failure to save the ring,<ref>'''Halo 2''', campaign level ''[[The Heretic]]''</ref> although he was subsequently appointed an [[Arbiter]].<ref>'''Halo 2''', campaign level ''[[The Arbiter]]''</ref>
[[File:H2A - Autumn.jpg|thumb|left|250px|The UNSC ''Pillar of Autumn'' flees as Reach is orbitally bombarded.]]

Shortly after the destruction of the first Halo ring, the High Prophet of Regret accidentally stumbled upon the human homeworld, [[Earth]], while looking for evidence of Forerunner artifacts. Ill-equipped for a full-scale invasion, Regret managed to launch a brief assault on the [[Africa]]n city of [[New Mombasa]] before [[Solemn Penance|his assault carrier]] escaped by making an in-atmosphere slipspace jump. Whether blind or intentional, this jump led the Prophet of Regret and the pursuing UNSC frigate [[UNSC In Amber Clad|''In Amber Clad'']] to a [[Installation 05|second Halo ring]].<ref>'''Halo 2''', campaign level ''[[Delta Halo (level)|Delta Halo]]''</ref> A [[Battle of Installation 05|brief military conflict]] between UNSC and Covenant forces ensued, during which time Regret met his end at the hands of the Demon. The ring itself was nearly activated, but was stopped by UNSC forces.<ref name="h2journey">'''Halo 2''', campaign level ''[[The Great Journey]]''</ref>

During the events on the second Halo, the two remaining Hierarchs used the Sangheili's failure to safeguard Regret as an opportunity to replace the Sangheili with Jiralhanae as their protectors and military leaders. The two Prophets had doubts about the Sangheili's loyalty to the Covenant cause, and used the opportunity to ensure that there would be no future dissidence in the Covenant. However, this move greatly angered the Sangheili, who threatened to resign from the High Council.<ref>'''Halo 2''', campaign level ''[[Sacred Icon]]''</ref>
{{Clear}}

===Civil war===
[[File:Schism 2.png|thumb|250px|Covenant Sangheili and Jiralhanae battle each other upon the onset of the Great Schism.]]
{{Main|Great Schism}}
Following the death of the Prophet of Regret, the Prophet of Truth gave the Jiralhanae command over the Covenant's fleets. Once there were enough Jiralhanae in positions of power, Truth secretly ordered them to commit genocide on the Sangheili. The [[Sangheili Councilor]]s, who had been summoned to the [[Control Room (Installation 05)|Control Room]] of Installation 05 to witness the commencement of the Great Journey, were either assassinated or imprisoned by Tartarus and his Jiralhanae. The rest of the Sangheili revolted, enlisting the help of some of the Mgalekgolo and Unggoy.<ref>'''Halo 2''', campaign level ''[[Uprising]]''</ref> While Truth had orchestrated to remove the Sangheili from power with the more easily manipulated Jiralhanae, the Prophet underestimated the speed with which his former protectors would recover from this initial attack. 

A massive battle ensued within High Charity and the surrounding space, beginning a civil war known as the Great Schism. While High Charity was consumed by internal conflict, another crisis struck that sealed the doom of the Covenant's holy city. The Flood-controlled UNSC frigate [[UNSC In Amber Clad|''In Amber Clad'']] made an unexpected slipspace jump inside the dome and crashed into one of the towers, initiating a full-scale infestation of the city. The Prophet of Mercy was killed during the Flood attack, with Truth leaving him to die while he made his own escape. The city and its millions of inhabitants were completely overrun by the infestation, becoming a massive [[Flood hive]]. This loss came at the worst possible moment in the Covenant's campaign against humanity, crippling their already exhausted and now divided forces.<ref>'''Halo 2''', campaign level ''[[Gravemind (level)|Gravemind]]''</ref>

[[File:Chiefarbiter.jpg|thumb|left|250px|An alliance was made with the seceding Sangheili and humanity.]]
However, these losses, among another factors, helped to form a tentative alliance with the Sangheili and humanity. The Arbiter Thel 'Vadam had discovered the truth about the Halo rings, and with the help of several of ''In Amber Clad'''s human crew members managed to prevent the second ring from firing and defeat the Jiralhanae forces defending it.<ref name="h2journey"/> While [[Joyous Exultation Covenant|one group]] had [[Onyx Conflict|initial conflicts]] over the Forerunner world of [[Onyx]],<ref>'''Halo: Ghosts of Onyx''', ''page 378''</ref> the [[Fleet of Retribution|Sangheili]] under the command of Rtas 'Vadum joined with the UNSC in order to mutually defeat the Jiralhanae, Truth, and the Flood. This alliance was initially uneasy, but the two species gradually learned to cooperate as their reliance in battle increased.

Truth escaped in the Forerunner Dreadnought, then used to provide power to High Charity. However, [[John-117|SPARTAN-117]], the infamous Demon, managed to fight his way aboard the Dreadnought right before it took off. While the Covenant fleet orbiting the holy city began to do battle with each other, the Dreadnought managed to enter slipspace and retreated to Earth.<ref name="h2journey"/>

===Final push===
{{Main|Battle of Voi|Battle of Installation 00}}
[[File:TruthDeath-large.jpg|thumb|right|250px|The Arbiter executes the Prophet of Truth, bringing an end to the Covenant.]]
Despite the loss of High Charity, the Prophet of Truth and his loyal Jiralhanae-led forces continued their pursuit of the Great Journey. They concentrated all of their available forces on Earth, near the former site of [[New Mombasa]], [[Kenya]], in order to claim the Forerunner artifact that the Prophet of Regret was originally looking for: the [[Portal at Voi]] to [[Installation 00|the Ark]]. Truth arrived in his Dreadnought and landed in the middle of the portal that his ships had uncovered, preparing for the moment of ascension to the next step.<ref>'''Halo 3''', campaign level ''[[Tsavo Highway]]''</ref> While the UNSC managed to inflict casualties upon Truth's fleet and the Covenant forces on the ground, it was not long until the UNSC forces on Earth were almost completely exhausted. Despite the UNSC's attempts to stop him, Truth successfully activated the portal and the Dreadnought retreated through, accompanied by the remaining loyalist fleet.<ref>'''Halo 3''', campaign level ''[[The Storm]]''</ref> Momentarily delayed by a small-scale Flood infestation on Earth, the UNSC and their defected Sangheili allies followed Truth's fleet through the portal to the Ark, intent on stopping Truth from activating the Halo Array.<ref>'''Halo 3''', campaign level ''[[Floodgate]]''</ref>

Upon arrival at the Ark, Truth barricaded himself inside the [[Installation 00 Citadel|Citadel]], the control center for the Halo rings, and prepared to initiate the Great Journey. However, the UNSC and Sangheili forces eventually broke through the defenses around the Citadel despite heavy resistance from the Covenant loyalist forces.<ref>'''Halo 3''', campaign level ''[[The Ark (level)|The Ark]]''</ref> Ignoring the arrival of the Flood-infected High Charity which immediately began a widespread infestation of the Ark's surface, the UNSC-Sangheili alliance launched an immediate last-ditch assault on the Citadel. Although Truth's forces mobilized all of their available assets to prevent their enemies from reaching the Citadel, they were defeated after a [[Battle of the Citadel|swift battle]]. SPARTAN-117 and Arbiter Thel 'Vadam formed a temporary alliance with the Flood and forced their way to Truth. In his final moments, the Prophet of Truth managed to initiate the Halo rings' activation sequence, although his victory was short-lived as John-117 and the Arbiter soon made their way to his location. The Spartan canceled the activation before the rings could fire and the Arbiter killed Truth in vengeance, finally stopping the Covenant once and for all.<ref>'''Halo 3''', campaign level ''[[The Covenant (level)|The Covenant]]''</ref>

===Splintering===

{{Main|Covenant remnants|Post-Covenant War conflicts}}
With the Prophet of Truth killed, and most of the loyalists' known fleet destroyed by the Sangheili fleet above the Ark, the Covenant as an entity was all but destroyed. Following Truth's death at the hands of the Arbiter, the remaining San'Shyuum, their population reduced to near extinction,<ref name="bestSan">'''[[Bestiarum]]''' ''San'Shyuum section''</ref> went into hiding and have not been sighted by the Sangheili since.<ref name="return">'''[[Halo: Evolutions - Essential Tales of the Halo Universe|Halo: Evolutions]]''' '''[[The Return]]''' ''page 506''</ref> The rest of the former member races scattered. While Thel 'Vadam succeeded in forming a new government known as the [[Swords of Sanghelios]] based on [[Sanghelios|their homeworld]], the Sangheili, having renounced the Great Journey, began to [[Blooding Years|fight amongst their own ranks]] over the particulars of their faith, some forming their own splinter factions.<ref>'''Halo: Glasslands''', ''page 20''</ref> Most of the Jiralhanae continued to oppose the Sangheili until at least [[2559]],<ref name="return"/> although some Jiralhanae chose to serve under their former masters.<ref>'''Halo: Glasslands''', ''page 136''</ref> Many Kig-Yar returned to their ancient ways as raiders and traders,<ref>'''Halo: Glasslands''', ''page 247''</ref> and most Huragok were thought to have fled, though no one knew where.<ref name="Halo page 256">'''Halo: Glasslands''', ''page 256''</ref> Many members of the former Covenant also [[asylum seeker|sought asylum]] on Earth, most notably in the city of [[Rio de Janeiro]].<ref name="departure">'''Spartan Ops''', S1E1 ''Departure''</ref>

In the wake of the dissolution of the Covenant, many individual commanders sought to seize control of the hegemony's former military assets for themselves, many of them forming disparate fiefdoms claiming to be ''the'' Covenant.<ref name="HE5">'''[[Halo: Escalation]]''', ''[[Halo: Escalation Issue 5|Issue #5]]''</ref> Others retreated from active involvement in interstellar affairs, maintaining the ships and weaponry for defense of their own lands. With large portions of the Covenant's infrastructure in shambles, intact ships in particular were considered a valuable commodity among the Sangheili.<ref>[https://web.archive.org/web/20141012164920/https://blogs.halowaypoint.com/en-us/blogs/headlines/posts/the-halo-bulletin-4-16-14 '''Halo Waypoint''': ''The Halo Bulletin: 4.16.14'']</ref> While many former members of the hegemony discarded the Covenant's religion in favor of more pragmatic pursuits, others continued to adhere to the core tenets of their former religion, namely the worship of the Forerunners as gods.<ref name="Thursday War">'''[[Halo: The Thursday War]]'''</ref> The [[Banished]] amassed a considerable degree of power in the aftermath of the Covenant's destruction.<ref>[https://www.youtube.com/watch?v=l4axn4oo_KE '''YouTube''': ''Halo Wars 2 E3 Trailer BTS'']</ref>

==Government and politics==
[[File:H2A-ThelBeforeCouncil.jpg|thumb|250px|left|Thel 'Vadam on trial at the [[High Council Chamber]].]]
For the majority of its existence, the two ruling classes of the Covenant were the San'Shyuum and the Sangheili, though the former held greater sway over the Covenant due to their status as "the voice of the gods".<ref name="Ency112"/> On the outbreak of the Great Schism, the Sangheili were cast out and the Jiralhanae replaced the Sangheili as the secondary ruling class. The Covenant had ten echelons of government,{{citation needed}} the highest echelon being the [[High Council]], which was responsible for making all important decisions. Prior to the Great Schism, it was made up of over two hundred members of Sangheili commanders and San'Shyuum ministers,<ref>'''Halo Encyclopedia''' ''page 345''</ref><ref name="Harvest">'''Halo: Contact Harvest''' ''page 271''</ref> and was ruled by the three San'Shyuum [[Hierarchs]]. These Hierarchs were the highest political and religious authority in the Covenant. For each new Age, three new Hierarchs were 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.<ref name="Harvest"/><ref name="ency119">'''Halo Encyclopedia''' ''page 119''</ref> This Oracle was a Forerunner artificial intelligence found within the Dreadnought which sat at the center 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 was steeped with political bribes, blackmail and manipulation of the San'Shyuum [[Philologist]].<ref name="ency119"/><ref>'''Halo: Contact Harvest''' ''page 274''</ref>

The High Council consisted of [[San'Shyuum High Councilor|San'Shyuum]] and [[Sangheili High Councilor]]s, who were extremely important to the Covenant society. The High Council served as 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 the [[Council of Masters]]. The Council of Concordance was responsible for the creation of the [[Ratification Parley]] and [[Writ of Union]].<ref>'''[[Halo 2: Original Soundtrack]]''', ''Volume 1''</ref> The Council of Masters was a controlling group within a [[Covenant fleet]] that dictated the needs of fleet and military forces.<ref>'''Halo: The Cole Protocol''', ''page 144''</ref> Below the councils, numerous ministries exist within the Covenant government, each of which dictates a single, but important role within the governmental body of the Covenant. Each ministry was led by a [[Minister (title)#Covenant ministers|San'Shyuum minister]]. A ministry's [[Vice Minister|vice minister]] served as an aid for the minister,<ref name="Halo page 154">'''Halo: Contact Harvest''', ''page 154''</ref> while numerous [[senior staffer|senior]] and [[junior staffer]]s served under both individuals.<ref>'''Halo: Contact Harvest''', ''page 149''</ref>

In truth, however, the San'Shyuum and Sangheili had an uneasy coexistence, and political infighting was very common behind the scenes. This stemmed from as far back as the Writ of Union, when the Sangheili begrudgingly accepted the alliance with the San'Shyuum, despite many Sangheili innately knowing the treaty technically meant their species' surrender to the Prophets.<ref>'''Halo: Broken Circle''', ''page 48''</ref> Over the Covenant's history, high-ranked San'Shyuum manipulated the Sangheili and sought to keep them without strong leaders of their own in order to keep them subservient to the Prophets' rule. The most prominent example of this is the San'Shyuum's perversion of the traditional Sangheili title of [[Arbiter]] from a position of great power and honor into a badge of shame, and a means by which to silence those they felt might challenge the Hierarchs' power.<ref name="h2aterm">'''Halo 2: Anniversary''' - ''[[Terminal/Halo 2: Anniversary|Terminals]]''</ref> In other cases where appointing an Arbiter may have been inconvenient, Sangheili commanders deemed to wield too much influence with their kind were quietly exiled to the fringe worlds of the Covenant empire; an example of this was the fate of [[Imperial Admiral]] [[Xytan 'Jar Wattinree]].<ref name="xytan"/> The hidden distrust between the two species became an all-out war during the Great Schism.

==Religion and culture==
{{Main|Covenant religion}}
[[File:H2A - Battle of Delta Halo.jpg|right|thumb|250px|The Great Journey's objective was to find and activate the Halo rings, and so ascend to godhood.]]
Covenant society had a distinct caste-based societal system with a strong theocratic underpinning.<ref name="Ency112">'''[[Halo Encyclopedia]]''' ''page 112''</ref><ref name="BungieCovy">[http://halo.bungie.net/News/content.aspx?type=topnews&cid=697 '''Bungie.net''': ''Covenant Primer: The Best of the Bestiary'']</ref> In the Covenant caste system, one's position in the hierarchy was dictated largely by their species. With the San'Shyuum and Sangheili leading the Covenant's religiopolitical and military affairs, respectively, most of the other species served either as warriors or manual labor.

The Covenant's culture and religion was based solely on the worship and reverence of the Forerunners. Long ago, the San'Shyuum managed to decipher some of the data stored on terminals aboard the Forerunner Dreadnought, thanks to the Forerunners' robust translation systems. However, even then they were unable to fully comprehend the subtle meanings of many Forerunner glyphs.<ref name="Ency112"/> The San'Shyuum incorrectly interpreted the activation of the Halo Array as a means of transcending mortality, a process they came to call the "Great Journey". They did not understand that the Array had been designed to eradicate the Flood, specifically by triggering a galactic holocaust and killing all sentient life within the galaxy. They arrived at the conclusion that the Forerunners had ascended to godhood and left other species of the galaxy to their fates.<ref name="Ency112"/> Because of this, the Covenant devoted itself to searching for and recovering of Forerunner artifacts. At several points in the Covenant's history, this desire to reclaim Forerunner technology has resulted in the hegemony declaring war against non-compliant species, the most recent instance being their war against humanity. In Covenant society, personal vendettas are not tolerated,<ref name="flood">'''[[Halo: The Flood]]''' ''page 95''</ref> although many conflicts in the Covenant's past have been sparked by vendettas.<ref>'''[[Halo: Contact Harvest]]''' ''page 150''</ref>

[[File:Covie Lance1.jpg|left|thumb|250px|Kig-Yar and Unggoy listening to the sermons of a Prophet.]]
The Covenant used commerce as a form of economy. As the Covenant's cohesion was grounded in its belief of working to obtain and sharing Forerunner technology, every member of the Covenant was given a form of employment<ref name="harv146"/> or a service to fulfill in exchange for goods and necessities. In the Covenant's culture, service for salvation was the moral motivation for the entire population.<ref name="regret">[[Media:Humans hunted.ogg|''Halo 2'' dialogue]], [[Prophet of Regret]]</ref> Despite this, there was discrimination within the Covenant: The lesser species were treated as second-class citizens with little political or representative voice or power.

The Covenant were always eager to add new species to the faith,<ref>'''[[Halo: Contact Harvest]]''' ''page 51''</ref> so long as they pledged allegiance to the San'Shyuum as their supreme leaders and the Great Journey as their religion.<ref>'''[[Halo: Contact Harvest]]''' ''page 50''</ref> Client races were in all essence enslaved by the Covenant, forced to live a completely different way of life, and if unlucky enough, had their entire culture and history erased. The client races were held together by a common belief; the slave races were driven by the religion which they had been forced to accept. Most races were only kept for their varying skills to be exploited, rather than to be a part of a flourishing empire. However, some races such as the Sangheili and Jiralhanae benefited significantly from the new technology that the Covenant brought, and weren't simply enslaved like the Unggoy.
{{clear}}

==Species==
The Covenant is made up of a variety of alien species from different parts of the galaxy. Organized into a caste system by the San'Shyuum, the different species of the Covenant are united by their blind faith in the promise of the Great Journey.<ref>'''[[Halo Encyclopedia]]''' ''page 14''</ref> In addition to the core member species listed below, there are a number of peripheral client species—known collectively as the [[Covenant fringe]]—that were never fully integrated into the Covenant, though some provided various advantages to the hegemony.<ref name="wp axl">[https://www.halowaypoint.com/en-us/universe/characters/axl '''Halo Waypoint''': ''Axl'']</ref>

However, not every species encountered by the Covenant was deemed worthy of even providing them with conversion in exchange for services, though their worlds still fell under Covenant control. These species were poorly documented by the [[Sangheili]] and have not been contacted nor cataloged by the [[Unified Earth Government]], even after the Covenant's fall.<ref>[https://www.halowaypoint.com/en-us/community/blog-posts/canon-fodder-bulkhead-banter '''Halo Waypoint''': ''Canon Fodder - Bulkhead Banter'']</ref>

===San'Shyuum===
{{Main|San'Shyuum}}
[[File:Regret render.png|100px|right|link=San'Shyuum]]
The highest political caste in the Covenant, the San'Shyuum, or "Prophets" as they are known by humans, led the Covenant and exerted complete control over all religious and political affairs. Though physically weak, Prophets wielded power through absolute command of the Covenant and through scavenged [[Forerunner]] technology, leaving the task of conquest to the Sangheili and the other races. Along with the Sangheili, the San'Shyuum had members on the Covenant High Council.
{{clear}}

===Sangheili===
{{Main|Sangheili}} 
[[File:Halo 2 Anniversary Zealot.png|140px|right|link=Sangheili]]
The Sangheili, or "Elites" as they are known by humans, served as the military leaders of the Covenant before the Great Schism. Along with the San'Shyuum, the Sangheili were one of the two founding races of the Covenant, and were the only race other than the San'Shyuum to have members on the High Council. The Sangheili are the only race within the Covenant permitted to build and command starships within the Covenant, though the crews are always composed of a mix of races.<ref>'''Sybex Halo PC Guide''' ''page 48''</ref>

===Jiralhanae===
{{Main|Jiralhanae}}
[[File:Reach - Chieftain.png|140px|right|link=Jiralhanae]]
The Jiralhanae, or "Brutes" as they are known by humans, were the most recent addition to the Covenant, and served as soldiers and bodyguards within the Covenant military until their promotion during the Great Schism. Although initially of low status within the hierarchy, the Jiralhanae gained greater prominence within the Covenant prior to the Great Schism, with the Chieftain of the Jiralhanae, Tartarus, answering to the Hierarchs themselves. After the Sangheili were deposed, the Jiralhanae were given command of the Covenant military.

===Lekgolo/Mgalekgolo===
{{Main|Lekgolo|Mgalekgolo|Sbaolekgolo}}
[[File:HReach - Mgalekgolo.png|140px|right|link=Mgalekgolo]]
The Lekgolo are a race of worm-like creatures that can combine to form large, intelligent assemblages called Mgalekgolo, known by humans as "Hunters". Clad in nearly impenetrable armor and armed with their trademark Assault Cannon, they served as the Covenant's heaviest ground troops. Many of these creatures joined the Sangheili during the Great Schism.
{{clear}}
===Unggoy===
{{Main|Unggoy}}
[[File:HReach - Unggoy.png|140px|right|link=Unggoy]]
Hailing from Balaho, the Unggoy, or "Grunts" as they are known by humans, were the most common and low-ranking caste of the Covenant. They breathe methane gas, and thus must wear a large tank on their back full of methane to survive on other planets. Relations between the Unggoy and the Kig-Yar are strained in the best of times. Many of these creatures joined the Sangheili and the Jiralhanae during the Great Schism.
{{clear}}
===Kig-Yar===
{{Main|Kig-Yar|T'vaoan}}
[[File:JackalMinor.png|140px|right|link=Kig-Yar]]
The Kig-Yar, or "Jackals" or "Skirmishers" as they are known by humans,<ref name="flood"/> were the scouts and marksmen of the Covenant military due to their superior senses. They were among the lower Covenant castes and are about 6'2" tall.
{{clear}}
===Yanme'e===
{{Main|Yanme'e}}
[[File:Yanmee H2A.png|140px|right|link=Yanme'e]]
The Yanme'e, or "Drones" as they are known by humans, are flying, insectoid species that served almost exclusively as engineers in the Covenant Empire. They were eventually replaced by the Huragok, and were used as aerial combatants against the UNSC, who are inexperienced at fighting airborne infantry.
{{clear}}
===Huragok===
{{Main|Huragok}}
[[File:Engineer renderized.png|140px|right|link=Huragok]]
The Huragok, or "Engineers" as they are known by the humans, are an artificial species created by the Forerunners. They only conversed with the San'Shyuum or individuals who learn their language.<ref>'''[[Halo: Contact Harvest]]''', ''page 55''</ref> The Huragok performed the physical labor of excavating and gathering data on Forerunner artifacts. In military terms, they were generally a non-militant race. Many of the Huragok joined the Sangheili during the Great Schism.

==Military==
{{Main|Covenant military}}
[[File:H2A Terminals - Sacred Consecration 2.jpg|thumb|right|250px|The [[Fleet of Sacred Consecration]], made up of {{Class|CAS|assault carrier}}s and {{Class|CCS|battlecruiser}}s.]]
The Covenant maintained pervasive armed forces to enforce order, conduct atmospheric and space combat operations, and generally carry out the Covenant's will throughout space. Unlike the [[UNSC]], however, the Covenant lacked a single unified military arm, and its armed forces were instead comprised of several organizations overseen by various ministerial bodies.<ref name="fb">'''[[Halo: Fleet Battles]]''', ''Core Rulebook - page 7''</ref> The Covenant's military capability was most overtly embodied in its spaceborne [[Covenant fleet|fleets]], ranging from small [[battle group]]s to entire armadas. Various task-based groups served under these fleets, including the occupational ground forces and the [[Special Warfare Group]], which contained the [[Special Operations|Special Operations Division]].

Covenant troops were heavily segregated by species, with the [[Sangheili]] originally serving as their leadership caste. In the field, [[Unggoy]] were deployed as cannon fodder [[file]]s, [[Kig-Yar]] were used as support and snipers, and Sangheili were commanders and fought in warrior [[lance]]s. Weapons and technology were restricted by species and rank; only Sangheili received [[Sangheili personal energy shield|personal energy shields]] and [[energy sword]]s, only Kig-Yar received [[Kig-Yar point defense gauntlet|point defense gauntlets]], and Unggoy only received basic weapons and [[Unggoy combat harness|armor]] depending by rank. The reasons for these restrictions were often cultural; for instance, Sangheili viewed wielding shield gauntlets as dishonorable and that "lesser species" did not deserve their privileged weapons. This discrimination among the Covenant military was centuries old, but the dynamic was occasionally changed by violent rebellion. The [[Unggoy Rebellion]] caused Sangheili to mix their units with Unggoy and give them better training. Likewise, the [[Great Schism]] put [[Jiralhanae]] in command of former Sangheili units, gave them [[Jiralhanae power armor|personal shielded armor]], and made their tribal [[pack]]s a prominent military unit.

== Technology ==
[[File:Charging Zealot.png|thumb|right|250px|[[Energy shielding]] and [[active camouflage]] were reverse-engineered from Forerunner technology.]]
Covenant technology has been often described as more imitative rather than innovative,<ref name="copyme">'''Halo: The Fall of Reach''', ''page 241'' (''"The Covenant’s science is imitative rather then innovative, a by-product of this societal ‘absorption,’"'' Dr. Halsey continued. ''"This is not to say that they are lacking intelligence, however. During our first encounter they gathered computer and network components from our destroyed ships... and they learned at an astonishing pace."''); '''2010 edition''', ''page 275''</ref><ref name="copymetwo">'''Halo: First Strike''', ''page 87'' (Cortana: ''"The Covenant were imitative, not innovative; at least, that's what all the ONI intelligence gathered on the collection of alien races had reported. She had thought this was exaggeration, propaganda to bolster human morale."'')</ref> as they are based largely on mimicry and reverse-engineering of the leftover Forerunner artifacts they have discovered. Such examples are their exceedingly accurate [[slipspace]] [[astrogation|navigation]], near-instantaneous [[Slipstream space#Communications|interstellar communication]], the manipulation of extremely high volumes of plasma energy from sublight travel, short-range translocation of matter, a great influence over gravity and repulsor-based technologies,<ref name="wp cov">[https://www.halowaypoint.com/en-us/universe/factions/covenant '''Halo Waypoint''': ''Covenant'']</ref> and man-portable application of energy manipulation.<ref name="techtier">'''[[Bestiarum]]''': ''[[Technological Achievement Tiers]]''</ref> Much of the Covenant's rapid technological advancement was made by stripping Forerunner [[Shield world#Conservation sphere|shield worlds]] of useful matériel early in the hegemony's existence.<ref>'''Halo Wars''', [[Halo Wars Timeline Events|Excerpt from ''The Punished Deeds, Vol. III'']]</ref>

Although innovation is not one of the Covenant's strong suits, the Covenant has shown considerable advancement in bridging the technological gap with newly-encountered species. For example, in the first encounter of the Human-Covenant War, the Covenant learned of the humans' computer systems and of its language from salvaging human computer and network components from destroyed human ships.<ref name="copyme"/> This knowledge benefited the Covenant greatly in understanding the humans' military operation, to the extent that the UNSC enacted the [[Cole Protocol]] to deter the Covenant from finding human [[Human colonies|colony worlds]] and [[Earth]]. In another scenario, during the preliminary of the [[Fall of Reach]], the Covenant crippled [[Reach]]'s telecommunication network to prevent the colony world from contacting reinforcements and placed numerous [[Covenant spire|teleportation spires]] to deploy its forces without having to face directly with the planet's orbital defenses.<ref name="Reachgame">''Halo: Reach''</ref>

In Covenant culture, there are religious taboos that prevent them from fully exploring what the Forerunners employed to create that technology.<ref name="ency224">'''[[Halo Encyclopedia]]''' ''page 224''</ref> In some cases, Covenant technology imitates the effects of the Forerunner technology it is based on while the underlying science remains largely beyond their grasp. An example of this is the Covenant's predominant use of [[plasma]] in their weapons rather than the more exotic [[hard light]] and particle streams utilized by the Forerunners,<ref name="EVGplasma">'''[[Halo 4: The Essential Visual Guide]]''', ''page 103''</ref> or the Covenant's [[pinch fusion reactor]]s in contrast to the Forerunners' ability to harness [[vacuum energy]]. The Covenant also never developed advanced [[Artificial intelligence|AI]] technology due to their religious doctrine; they believed that a [[Associated intelligence|powerful AI]] had once betrayed the Forerunners, and as such they had a ban on actually sapient machine intelligences. The few Covenant AIs that have been encountered include [[Ascendant Justice's AI|an AI]] that was stationed aboard the ''[[Ascendant Justice]]'' and destroyed by [[Cortana]],<ref>'''[[Halo: First Strike]]''' ''''page 170''</ref> [[Truth and Reconciliation's AI|one]] based on the ''[[Truth and Reconciliation]]'', as well as the [[Seeker (AI)|Seeker]], sent to infiltrate UNSC systems and alert the Covenant to the location of Earth. Cortana's copy also referenced several AIs being present in the ''[[Unyielding Hierophant]]''<nowiki>'</nowiki>s systems when the Spartans infiltrated the station.<ref>'''[[Halo: First Strike]]''' ''page 320''</ref>

The Forerunners' ubiquitous [[hard light]] technology was never completely understood by the Covenant,<ref name="wages">'''[[Halo: Evolutions - Essential Tales of the Halo Universe]] Volume II''', ''"[[Wages of Sin]]"'', ''page 291''</ref> although they managed to develop at least one hard light-based device in the [[Prelate]]s' shield gauntlets.<ref name="Shadow of Intent">'''[[Halo: Shadow of Intent]]''', ''page ??''</ref> However, they did possess advanced energy field shaping and complex [[holography]]. This technology was advanced enough to produce realistic and tangible simulacra of physical objects. The [[holo-drone]], for example, generates an independent decoy of the operator capable of inflicting physical harm on the enemy despite its incorporeal nature;<ref>'''Halo 2''', campaign level ''[[The Oracle]]''</ref> the [[Type-27 hologram|T-27 holographic decoy]] is a more basic variation of this concept. The Covenant applied forcefield technology in a broad range of roles, from the San'Shyuum's spherical [[stasis field]]s to contain beverages such as tea<ref name="Halo page 154"/> to the enormous [[Energy barrier|fields]] used to hold in ''High Charity''<nowiki>'</nowiki>s atmosphere while the holy city's exterior dome was still under construction.<ref>'''Halo: Broken Circle''', ''page 20''</ref><ref>'''Halo 2: Anniversary''', ''[[Terminal/Halo 2: Anniversary|Terminal 8]]''</ref>

Covenant architecture is known for its curved, organic and sophisticated looking style, primarily based on the aesthetic tastes of the [[San'Shyuum]] with loose connections with [[Sangheili]] designs. Even military vehicles were fashioned after San'Shyuum aesthetics early on, incorporating many of the Sangheili designs over the Covenant's history.<ref name="wp cov"/> Constructed of distinctive purple, blue or white metal, these colors are the main focus of Covenant design and distributed throughout their starships, vehicles, and weapons. The materials they use are unknown to the UNSC but are very strong and resilient.

The Covenant possess a variety of medical technologies, including the life-extension treatments the San'Shyuum have used for some time.<ref name="bestSan"/> The San'Shyuum Prelates were also know to have used a form of biological augmentation to greatly enhance their normally frail bodies.<ref name="wp cov"/> As an idiosyncrasy of their warrior culture, the Sangheili view the notion of doctors as dishonorable.<ref>'''Halo: The Cole Protocol''', ''page 143''</ref> However, as injuries are an inevitable byproduct of combat, the Covenant military still employs a number of medical amenities. Among these are [[automated surgery suite]]s, featured on Covenant ships to treat wounds received in combat,<ref>'''Halo: Contact Harvest''', ''page 259''</ref> and [[magnetic splint]]s which are used to hold broken bones in place. The [[Huragok]] (both the common [[Builder]] kind and the [[Lifeworker]] variation) also provided medical aid in addition to their primary role of maintaining Covenant technology.<ref name="Halo page 256"/><ref name="Halo page 152">'''Halo: Hunters in the Dark''', ''page 152''</ref> It was known that even after suffering major injuries, after only minutes of treatment the patient would feel back to normal without as much as a scar to show for it.<ref name="Halo page 152"/><ref>'''Halo: Hunters in the Dark''', ''page 349''</ref>

===Spacecraft===
[[File:1771441-gallery.png|thumb|right|250px|The ''[[Resplendent Fervor]]'' [[Modular Dispersal Technology|separates its aft section]] while the bow enters [[slipstream space]].]]
For the Covenant species, interstellar travel was made easy due to the reverse-engineered technology. Like humans, Covenant vessels can enter [[Slipstream space]] and travel significantly faster than light. However, the Covenant equivalent of the [[Shaw-Fujikawa Translight Engine]] is far more efficient and reliable, relying on a series of "micro-jumps" to maneuver through the slipstream. Covenant vessels do not suffer the "temporal fluidity" of faster-than-light to such a degree as human vessels, arriving at the precise time and location that they intend. However, after a slipspace jump Covenant vessels generally experience a temporary power outage, leaving the vessel vulnerable to attack. As a result, Covenant battlegroups are much more efficient when acting as a coordinated group, and can strike more quickly and decisively.<ref name="ency224"/>

Covenant starships use [[repulsor engine]]s for propulsion in space, rather than the more traditional [[fusion engine]]s utilized by humanity or the advanced [[reaction drive]]s used by Forerunners.<ref>'''Halo: Ghosts of Onyx''', ''page 331''</ref> 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.<ref name="ency224"/> Both starships and ground vehicles are equipped with various forms of [[anti-gravity technology]], allowing ships to hover easily inside an atmosphere and allowing frictionless movement of vehicles across terrain. The Covenant are also able to manipulate exceedingly large amounts of plasma energy by recycling detritus from sublight travel.<ref name="wp cov"/>

Covenant manufacturing plants, such as the [[Assembly Forges]], employ highly sophisticated manufacturing methods which allow them considerable freedom in the design of individual ships. While all Covenant vessels fall into one of several universal design patterns, every ship can be custom-made to fit the preferences of individual shipbuilders and fleet masters.<ref name="have s'moa">[https://www.halowaypoint.com/en-us/community/blog-posts/canon-fodder-have-s-moa '''Halo Waypoint''': ''Canon Fodder: Have S'moa'']</ref>

===Weaponry===
Most of the Covenant arsenal consists of [[plasma weaponry|plasma-based]] [[directed energy weapon]]s, but the Covenant are known to also utilize [[Pulse laser turret|pulse lasers]], [[particle beam weapon]]s, [[antimatter]] explosives and even chemical crystal-based weapons. Interestingly, Covenant weapon designs seem to defy known laws of mechanics; there is typically no form of [[Wikipedia:Radiative transfer|radiative]], physical, or electrical contact between the firing mechanism and "trigger" of a weapon. For these and other reasons, the workings of Covenant weaponry is generally beyond the comprehension of UNSC scientists.<ref>''[[Dr. Halsey's personal journal]]'', [[:File:Journal Needler.png|Needler analysis]]</ref>

[[File:Tyrant Plasma.png|thumb|left|250px|The Covenant favor plasma weapons, used for both their starships and ground forces.]]
Plasma weapons typically use a rechargeable power cell to provide power to their internal components. Covenant plasma weapons are effective but crude, and most automatic-fire plasma weapons are prone to overheating. To compensate, most weapons have vents that open to discharge excess heat and plasma when they overheat, although such weapons are rendered inoperable as the excess heat is dissipated. Once the energy of the plasma weapon is depleted, it must be recharged or discarded. To date, the means by which plasma weapons can be recharged is still unknown to UNSC forces. The most remarkable handheld plasma projectile weapons are a variety of [[Type-25 plasma pistol|plasma pistol]] (by far the most widely used small arm) and the [[Type-25 plasma rifle|plasma rifle]]. Notable vehicular plasma weapons include various [[plasma cannon|cannons]] and [[plasma mortar|mortars]], while warships are armed primarily with [[Plasma turret|plasma torpedo turrets]].

Though rarer, the Covenant occasionally use projectile weapons, the most common of these being unconventional crystal-based weapons such as the [[Type-33 Needler]] and the [[Type-31 needle rifle]]. These weapons appear to use some type of chemical that forms a hard, razor-sharp crystal on contact with the atmosphere; [[Blamite|the material]] is mined on [[Suban]], one of [[Sanghelios]]' moons. Certain medium- to long-range weapons fire these crystals at high speeds, allowing them to strike targets accurately at long distance. Other mid-range weapons fire them at very slow speeds, and through unknown means "steer" them towards enemy targets. Needles fired in either of these ways will penetrate the flesh or armor of a target, and several seconds after coming to rest will explode into thousands of tiny, sharp fragments that can maim or cripple a target. When a certain number of needles have penetrated the same target, they will detonate simultaneously, producing a much larger explosion that kills the target instantly.
 
With the introduction of the Jiralhanae as a major military caste within the Covenant, their weapons found widespread use among their own kind. Utilizing crude, spike-like metal projectiles in place of plasma; conventional explosives and incendiaries; and sharp blades, they are more primitive, yet in many cases more dangerous -fitting, considering the nature of their creators. Brute weapons include the [[Type-25 Spiker|Spiker]] carbine, the [[Type-52 Mauler|Mauler]] shotgun-pistol, and the [[Type-25 Brute Shot|Brute Shot]] grenade launcher.

The Covenant employ melee weapons in addition to their already fearsome arsenal. The best known is the [[Type-1 energy sword|energy sword]], used solely by the [[Sangheili]]. Creating a double blade of superheated plasma, it has both ceremonial and martial value to Sangheili warriors and its possession is closely monitored. Another is the Jiralhanae [[Type-2 gravity hammer|gravity hammer]], which seems to be the Brutes' cultural equivalent to the energy sword. However, rather than using a blade of plasma, it generates a gravitational field which can cause tremendous damage within a several-meter radius.

===Vehicles===
Covenant vehicles use [[Boosted gravity propulsion drive|advanced anti-gravity technology for propulsion]], and are armed with directed-energy weaponry of varying potency. Though often faster than their UNSC counterparts, Covenant vehicles are more unstable over uneven terrain where the sudden changes affect handling. All Covenant vehicles (except for Jiralhanae vehicles) and structures 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 [[Excavator]]s. Recently, Jiralhanae vehicles and technology have been incorporated into the Covenant's arsenal. Though more primitive, they serve the Jiralhanae's need for power. Jiralhanae vehicles are not named after spiritual entities, and rather than being a series of Covenant vehicles are regarded as native Jiralhanae technology.

Befitting its vastness, the governance of the Covenant's interstellar dominion was highly complex; occasionally worlds or entire sub-domains vanished from the records maintained at High Charity, only for contact to be re-established decades later. The [[High Council]] was responsible for the administration of these interstellar territories, assigning tithes and levies, and allocating resources across the numerous member worlds.<ref>''Halo: Warfleet'', p. 52</ref> San'Shyuum governors handled administrative duties on a local scale; most of them joined the rest of the species on their mass exodus during the Great Schism.<ref name="warfleet 54">''Halo: Warfleet'', p. 54</ref>

Some species, such as the [[Kig-Yar]] and [[Lekgolo]], had created colonies of their own before their incorporation into the Covenant. These worlds would be absorbed into the empire after the species joined the Covenant. Covenant space would grow to include new worlds as the hegemony expanded throughout the spiral arm, and even [[Forerunner]] installations were settled by the Covenant. Despite the massive size of the empire, the Covenant would generally leave a newly discovered world untouched, unless the world held religious or practical significance.

*[http://myth.bungie.org/legends/encyclopedia/where.html#covenant Covenant] is a major city in Bungie's ''Myth'' series; it is home to the ''Total Codex'', a magical book that lists the fate of every being that will ever be born. Bungie later considered ''Covenant'' as a potential title for ''Halo: Combat Evolved''. [[Paul Russel]] joked that it ''"... sound[ed] like a bad 80's hair band."''<ref>'''Halo 3''' ''Legendary Edition'' special features disk</ref>
*The [[List of references to religion in Halo|Biblical]] Ark of the Covenant represented the will of God, in connection with the quote: ''"Your destruction is the will of the Gods...and we are their instrument."'' This references the Covenant's belief they carry through the will of their gods, the Forerunners.
