Reth

Reth was one of the Kig-yar rebels who settled on the Rubble with Human refugees. He was the leader of the Kig-yar forces at The Rubble, and bred an army of Unggoy on the surface of a planet in the same system, Metisette. His alliance with the Insurrectionists was merely a ruse by which he intended to acquire the location of the human homeworld, before wiping them out with his army. While they were believed to be rebels by both the humans and Covenant forces sent by the Prophet of Regret, Reth was actually acting under the orders of the Prophet of Truth, who had no faith in Regret's methods. Reth believed that in completing his mission, he would earn the Kig-yar their place at the Prophets' side. The Unggoy who served under Reth and his Kig-yar also believed they were rebels. They followed Reth because he had promised to give them Metisette.

He was killed in the chaos when the wrecked Rubble destroyed Metisette.
