Supreme Commander

A Supreme Commander is the overall commander of a particular fleet; in the Halo Graphic Novel, he is depicted as clad in bright violet armor, with a long cloak that wraps around his shoulders. This particular Supreme Commander was a friend and superior to Rtas 'Vadumee, and would later become the Arbiter. Interestingly enough this same Commander wears gold Zealot armour in his trail at High Charity. So Far only one has been seen. During The Civil War of the Covenant It is possible the brutes usurped these positions
