Sevatar was a high-ranking Jiralhanae warrior, serving as a Chieftain during the Covenant War and subsequently as a War Chieftain during the Brutes' ensuing conflict with the Sangheili. Sevatar was an extremely devout follower of the Covenant's religion, and, along with being a veteran of Truth's fleet at the Battles of Earth and the Ark, was left with a particularly strong vendetta against both the Elites and humanity following the Covenant War's end. Ironically, this would lead him to join the Banished in 2558, upon learning of Chieftain Lydus' intent to begin peace negotiations with the Swords of Sanghelios.
