Umbriss was a Human male Sith Lord of the True Sith Empire who trained Sadic as his apprentice during the Great Galactic War. During the war, Umbriss utilized Sadic as his personal assassin for several years until the Sith Lord incurred the wrath of another Sith Lord by the name of Darth Angral around the time of the Cold War with the Old Galactic Republic. Umbriss' transgressions caused the far more powerful Sith Lord to kill Umbriss and take his wealth and estate. Angral also took Sadic on as his own apprentice, who pledged eternal loyalty to his new Master.
