Lepidus

Lepidus was a powerful Jiralhanae Shipmaster of the CCS-class Battlecruiser Triumphant Declaration in the Fleet of Furious Redemption. He was the first Covenant to hear of the Key of Osanalan. He led some of the forces in the Second Battle of Earth, precisly in the Battle of Cleveland, where his troops tried to find the Key. It is assumed he was killed in either the above battle, or in the Battle of the Ark, but it is still unknown.
