Darth Oseth, nicknamed The Wolf was a Sith Lord of the New Sith Imperium and the brother of Azrael. He was romantically engaged with Darth Kayos until Geist Weiss killed her. He and Grand Admiral Barrel failed to defeat Bellatrix La Rouge's fleet at Ilum, leading to the latter's execution by Darth Exodeus' hands. Though Oseth avoided execution himself, his prestige had diminished and was soon challenged by Darth Umbra who defeated Oseth and froze him in carbonite. Oseth was later freed, but was killed by Geist Weiss when he learned Oseth planned to betray the Sith.
