Byral Fleetclaw Tunn, a Greatrat, was son of Gormad Tunn, and as such potential heir to his father as Firstblade leader of the Rapscallion army. After Gormad's death, Byral and his brother, Damug Warfang, fought for the honor. Due to cheating on Damug's part with assistance from Lugworm, Byral was killed when Damug slammed him in the head with a boulder from a cord.
