Ulfast was the oldest and quietest son of Ulfang the Black, High-chieftain of the Ulbarim (S. "Homeless Host"). Ulfast yielded to his youngest brother, Uldor, rather than contest his father's Lordship. He became the High Priest of the Ulbarim, and served as Uldor's sancrosanct advisor. Bloodthirsty, like his father and brothers, he helped betray his clan's Elven allies at the Battle of Unnumbered Tears. Borlach slew him during the fighting, just after he had slain Borlach's brother Borlad.
