Great Schism

The Civil War of the Covenant is a war between the two factions that split apart in November, 2552. After the Prophet of Regret was killed by the Master Chief, the Prophets instituted the Changing of the Guard due to the elites failing their duty of protecting the prophet from the Demon, and the prophets no longer felt safe under the guard of the elites.

The elites were enraged with this decision and in an attempt to regain some of their authority in the Covenant, the Elites threatened to resign from the High Council, but were not reimbursed. As if the High Prophet of Truth wanted the war, he ordered the assassination of many of the Elite Councilors, sending the Elites into a final fit of rage and beginning the war.

When war broke out on high charity the two sides of the war were decided, leaving the Covenant split in two, with one faction consisting mainly of the Prophets and their new guards, the Brutes. The other faction - the Elites, who had long been the Prophets' protectors, ever since they discovered the Forerunners. They are joined by the Hunters, as well as many of the Grunts. The Arbiter, who is seen as the leader of the Elites, seems to have sided with the humans at the end of Halo 2, as Sergeant Johnson helped him defeat Tartarus in the Control Room of Installation 05.
