For almost 30 years the battle between the forces of humanity and the Convenant, an aggressive collection of alien species, has raged across the galaxy. Countless moments of bravery and danger have made heroes on both sides of the war, but above all others stand the Spartan super-soldiers and their leader: the Master Chief, John-117.
Arbiter (Ripa 'Moramee): After his attempt to overthrow the leadership of his own clan failed, the Elite known as Ripa 'Moramee accepted the role of Arbiter hoping it would help restore his reputation. Known for his ruthlessness and intense rage, he was normally the last one standing at the end of a battle!
Prophet of Mercy: Mercy served as Philogist before becoming Hierarch, one of the highest authorities in the Covenant. He was present when the Oracle announced the Forerunners' connection with humanity and it was his promise to keep this secret that earned him one of only three high prophet positions.
