Halo 2 Serie 5 Arbiter

Disgraced by his failure at Halo, the former commander of the Fleet of Particular Justice has been given an ancient and terrible honor. To seek redemption for his crimes and sins, he must don the armor of The Arbiter - the violent instrument of the Covenant's wrath. Following a tradition thousands of years old, The Arbiter is given the authority to do whatever he is tasked with, but at a terrible price. He must obey the whims of the Prophets until death redeems him.
