 'Vadum, originally' Vadumee before the Covenant Civil War, is a veteran Covenant Elite and the second most prominent Elite character in the series after the Arbiter. The Last Voyage of the Infinite Succor explains how he loses his left mandibles; he is injured after fighting one of his friends, who was infected by the Flood. During the early events of Halo 2, 'Vadumee serves as a messenger between the Hierarchs and the Elite Council, as he is seen relaying messages between the two parties in the Prophets' chamber; when the Elites split from the Covenant, 'Vadumee joins his brethren in fighting the Brutes, dropping the "-ee" suffix from his surname to symbolize his resignation from the Covenant. In Halo 3,' Vadum is Shipmaster of the flagship Shadow of Intent, and supports Cortana's plan to follow Truth to the Ark. Along with the Arbiter,' Vadum leaves Earth to return to the Elite's homeworld with the end of the war. Rtas' Vadum is known for being a quick, smart, and ingenious tactician and an unparalleled fighter, especially with an Energy Sword and is an excellent leader. He expresses great care for his soldiers, even the Unggoy. He is eager to exact revenge on the Brutes after the Great Schism.
