Halo 2
Meanwhile, the disgraced Covenant commander is presented before the Prophet Hierarchs, Truth and Mercy, who acknowledge that though the destruction of Halo was his fault, he is no heretic. They offer him the honored position of Arbiter so that he can continue to fight for the Covenant. On his first mission to kill a heretic leader, the Arbiter discovers 343 Guilty Spark, who the Covenant calls an "oracle", and brings him back to "High Charity". Responding to Regret's distress call, "High Charity" and the Covenant fleet arrive at the new Halo, Installation 05, just before the Master Chief kills Regret. Bombarded from space, the Chief falls into a lake and is rescued by a mysterious tentacled creature.
