Ulwarth was one of Ulfang the Black's sons.
After entering Beleriand at Morgoth's bidding, Ulfang and his sons joined the service of Caranthir. Their purpose was to eventually betray the Elves, which they did in the Nirnaeth Arnoediad. They turned against their allies, attacking them in the rear. Ulwarth was slain by the sons of Bór, who had stayed loyal to the sons of Fëanor.
