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

The Swords of Sanghelios[1] are a break-away faction of the Covenant, led by the Sangheili. It was officially founded after they learned the truth about the Halo Installations near the end of the Battle of Installation 05 in November 2552. The Separatists no longer look to the San 'Shyuum for leadership, and thus have no defined leadership save for the surviving Sangheili Councilors, although Arbiter Thel 'Vadam and a few other head Sangheili, such as Rtas 'Vadum and Xytan 'Jar Wattinree hold positions of power within their ranks.


The Covenant Separatists are made up of the Sangheili, Grunt and Mgalekgolo castes (Unggoy and Mgalekgolo are sometimes seen in Halo 2 as allies, but never in Halo 3 to prevent confusion) within the Covenant's hierarchical society. The members of the faction were somewhat "united" at the beginning of the Great Schism, although the faction was "officially" formed when they learned the truth of the Halos and since both times, have been fighting the Covenant Loyalists, led by the San 'Shyuum and their Jiralhanae, Yanme'e, Kig-Yar and Grunt and Mgalekgolo loyalists.

It is speculated that this disgruntled faction is led by the Arbiter Thel 'Vadam, Shipmaster Rtas 'Vadum and Imperial Admiral Xytan 'Jar Wattinree. It is possible the remaining Sangheili Councilors command the faction from Sanghelios as aides to the Arbiter, offering their counsel to him as they once did with the San 'Shyuum. Fronts of this war include the Covenant holy city of High Charity, Installation 05, Earth, the Ark, and areas of space where Covenant ships operate.

Origins of the FactionEdit

The High Prophet of Regret led a horribly-planned mission to Earth, against the wishes of Truth, and was subsequently forced into the Battle of Earth, as he did not know that the planet was the Human homeworld. He escaped to Delta Halo, where he was killed by John-117. Regret's death was used as a justification by the remaining San 'Shyuum to replace the Sangheili with the Jiralhanae as their protectors. However, this move resulted in great turmoil within the Covenant, with the Sangheili threatening to resign from the High Council.

The High Prophet of Truth then gave command of the Covenant Fleets, the post previously held by the Sangheili, to the Jiralhanae. Once there were enough Jiralhanae in place, Truth secretly ordered the Jiralhanae to commit a vicious genocide of the Sangheili (disguised as a retaliation to a Sangheili revolt against the other Covenant factions) so they may replace them in society. The Sangheili responded, with the help of factions of Mgalekgolo, Unggoy, and a small amount of Kig-Yar and war broke out in High Charity with Jiralhanae and Sangheili fleets fighting each other in space around it. Later, most of the Sangheili Sangheili Councilors were assassinated by the Jiralhanae at the behest of the San 'Shyuum.

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.[2] However, the Arbiter persuaded the rest of the Sangheili to join with Humanity. While the two factions experience some friction, they learned to work with one another for their mutual survival.

During the events of Halo 3, the Sangheili fight alongside Humans in battle and save them from destruction.

The devastated UNSC Fleet in Earth's space were glad to accept the help of the superior Separatist warships. The Sangheili' understanding of enemy equipment and Covenant combat tactics proved invaluable in the Battle of Installation 00. Recurrently the heroes of the battle, 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 04B 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.

According to the Bestiarum in Halo 3's Limited Edition, the Unggoy were too indecisive to continue the rebellion and the true political motivation of the Mgalekgolo, if any, remains a mystery, although Mgalekgolo pairs could have followed the Sangheili they protect. Shipmaster Rtas 'Vadum stated that Truth's Fleet was destroyed. Had any of the Covenant survived on the Ark or in the ruins of their Fleet, they were either taken by the Flood or killed when the unfinished Installation 04B fired and destroyed itself and heavily damaged the Ark. At the end cutscene of Halo 3, victorious Sangheili depart for their homeworld to ensure its safety.

Over the next three years, 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.[3] The Sangheili appear in Halo 4 as part of the Covenant Remnant, but the current state of the Covenant Separatists is unknown.

  • Though the Covenant Separatists were called "Heretics" by the High Prophet of Truth, they should not be confused with the heretic faction led by the Sangheili Sesa 'Refumee which was destroyed by Arbiter Thel 'Vadamee, although they do have the same goal and beliefs. If remnants of the heretics were still around during the time of Halo 3, they and the Separatists would be on the same side, since the heretics also knew the truth about the Halo Array.
