The second son of Ulfang the Black, High-chieftain of the Ulbarim (S. "Homeless Host"), Ulwarth was an Unfaithful Easterling and Chieftain. He became his ruthless younger brother's chief lieutenant for, like Ulfast, he dared not contest Uldor's might. At the Battle of Unnumbered Tears, when the sons of Ulfang betrayed the Elves under Maedhros, Ulwarth led the left wing of his clan's army. Borthand slew him at the height of the fray, just after Ulwarth had dispatched Borthand's brother Borlach.
