Great Schism

The Covenant Civil War, also known by members of the Covenant as the Great Schism, is a war between the two factions that split apart in October, 2552.

Cause
After the Prophet of Regret was killed by the Master Chief, the Prophets, most notably the High Prophet of Truth, deemed it necessary to reorganize Covenant society, replacing the Elites with Brutes as the Prophets' protectors. The Elites viewed this as a violation of the principle the Covenant had been founded upon and threatened to resign from the High Council arguing that if Truth had not withdrawn the Phantoms that had been on route to Regret's location, the Prophet's death would have been prevented, and the Demon would have been killed.

To further deform the Covenant, Truth then gives command of the Covenant fleets (the Elite's job) to the Brutes. Once there are enough Brutes in place, Truth instigates the war by secretly ordering the assassination of all ruling Elites on and around High Charity, and presumably, the entire galaxy and beyond. This is disguised as a Brute insurrection against the Covenant to the Elites, the Hunters, and most Grunts, and as an Elite revolt to the other factions (excluding the Brutes and the Prophets).

Factions
When war broke out on High Charity, the two sides were quickly decided, leaving the Covenant split in two, though one could could say that it "truly" split when the Elites learned the truth about the Halos and the Great Journey. One force, the Covenant Loyalists consist primarily of the Prophets, Brutes, Jackels, Drones and, to a lesser extent, Grunts while the Covenant Seperatists fill out their ranks with the Elites, Hunters, and most of the Grunts. Furthermore, it appears that an alliance of circumstance galvanized in the control room of Delta Halo has tied the fate of the UNSC with that of the Covenant Separatists.

The Story so Far
Elites have been confirmed as allies to the humans of the UNSC. The "Story So Far..." page at halo3.com has stated: "Even with our newfound allies, the Elites, and their valiant and honorable leader, the Arbiter, we are still hopelessly outnumbered and at the mercy of the will of the Prophets, and the single minded force of the Flood."

Along with the Elites bio page: "The Elites have allied with their former Human foes in part because of a deep-seated resentment of the Prophet rule and in part because they actually understand the scale of the Flood problem."
