“There was honor in our Covenant once, and there shall be again!”

The Swords of Sanghelios[2] are a break-away faction of the Covenant composed predominantly of Sangheili. The movement was originally founded as a rebellion against the San'Shyuum-led Covenant, after the Sangheili learned of the true nature of the Halo Installations near the end of the Battle of Installation 05 in November 2552. Following the end of the Human-Covenant war, the Swords of Sanghelios rapidly grew in scope and influence, eventually taking control of Sanghelios and the majority of the Sangheili inner colonies. The Swords of Sanghelios are also one of a very select few breakaway Covenant factions to maintain diplomatic relations with humanity following the end of the war.

By March 2553 Thel 'Vadam had become the de facto leader of the Swords of Sanghelios and was still in power as of 2559. While the Swords of Sanghelios maintained a solid following, they met resistance from numerous conservative factions which held true to the Covenant religion or to the religion of ancient Sangheili.


Origins of the FactionEdit

The Swords of Sanghelios originated as alliance of Kaidons dedicated to the overthrow of a tyrannical Arbiter that was in control of the continent Qivro in the time before the Sangheili became a spacefaring race. They also assisted in making the rest of the Sangheili fall in line under the Writ of Union.[1]

Great SchismEdit

Main article: Covenant Separatists

The modern Swords of Sanghelios was reformed as a result of the Great Schism. Following a poorly-planned mission to Earth and a hasty retreat to Installation 05, the Prophet of Regret was assassinated by John-117. Using Regret's death as leverage, the Prophet of Truth set in action his plan to have the Jiralhanae usurp the Sangheili as military leaders of the Covenant. First Truth acted slowly, replacing his protection detail with Jiralhanae but soon, all-out war had broken out, following Truth's order that the Jiralhanae should rise up and kill the Sangheili.

In response to the betrayal, the Sangheili formed an organization colloquially known as the Covenant Separatists, supported by both many Unggoy and Mgalekgolo (though many of the latter species would return to the Loyalists' side soon after). During the early hours of the conflict, the movement lacked leadership, but several leaders would soon emerge. The Arbiter Thel 'Vadam rescued several the few surviving Sangheili High Councilors from Jiralhanae captivity and met up with Shipmaster Rtas 'Vadumee on Installation 05. Concurrently, Imperial Admiral Xytan 'Jar Wattinree took command of a large fleet of surviving Sangheili ships, including most of the Combined Fleet of Righteous Purpose.

Sangheili-Human AllianceEdit

The shaky-to-steady alliance between the Separatists and their former foes, the Humans, was forged entirely out of necessity. The UNSC forces were on the defensive, and they had two common enemies that wished for their extinction: the Covenant and the Flood. The alliance of circumstance was forged in the control room of Delta Halo, when Johnson and the Arbiter were coerced to unite in order to prevent Tartarus activating Installation 05.[3]

Xytan 'Jar Wattinree was unaware of the alliance forged by the Arbiter and so continued to treat humans as enemies. Unfortunately for him, however, he and his fleet were soon destroyed by a NOVA Bomb, leaving Thel 'Vadamee as the figurehead of the rebellion. Though not easily persuaded, the Arbiter was able to convince the rest of the Sangheili to join with Humanity. While the two factions experienced some initial friction, they learned to work with one another for mutual survival.

The devastated UNSC Fleet in Earth's space gladly accepted the help of the superior Separatist warships. The Sangheili understanding of Covenant combat equipment and tactics proved invaluable in the Battle of Installation 00. The battle's recurring heroes, Thel 'Vadam and John-117, fought alongside one another many times in the desperate and long conflict.

With Truth dead, High Charity destroyed, and the Ark essentially lost to the reborn Installation 08 firing, it is unknown what exactly the remaining Loyalist forces did. The Arbiter's presence at memorial services for John-117 indicated that in the wake of victory, Separatist and Human forces remained friendly to one another, as they both had made tremendous sacrifices in order to stop Truth and the Loyalist forces.

Some time following the destruction of the Covenant, the Fleet of Retribution division within the Covenant Separatists, formed the Swords of Sanghelios. Over the three years following the Human-Covenant war, the Sangheili continued to wage war against the remaining San'Shyuum and the Jiralhanae. At first, the Sangheili were at a major disadvantage, as millennia of depending on the San'Shyuum for technology meant that the Sangheili were unable to properly repair or replace the ships they lost in battle. The odds began to even out when the San'Shyuum "vanished" and the Jiralhanae began to fall back into internecine conflicts.[4]

Sphere of InfluenceEdit

The Swords of Sanghelios control the majority of Sangheili colonies.[5]



Unlike most other Covenant splinter groups, the Swords of Sanghelios are a secular government rejecting the Covenant religion and questions the traditional faith. However, many Sangheili still continue to worship the Forerunners, with some factions opposing the Swords of Sanghelios following the end of the Human-Covenant war.


Unlike more conservative groups, the Swords of Sanghelios accept females into their military ranks.[6] Additionally, they hold stricter maintenance and safety protocols, ensuring higher utilization rates and healthier crews.[7]

Notable membersEdit



  • Though the Swords of Sanghelios (or the Covenant Separatists as they were then known) were deemed "Heretics" by the High Prophet of Truth, they should not be confused with the heretic faction led by the Sesa 'Refumee, although the factions did share the same goal and beliefs. 'Refumee's faction was destroyed by Arbiter Thel 'Vadamee before he was aware of the truth behind the Great Journey.
