Gormad Tunn, a Greatrat, was the Firstblade leader of the Rapscallions and the father of Byral Fleetclaw and Damug Warfang. He attempted to conquer Salamandastron, but received mortal wounds from Lady Cregga Rose Eyes and died shortly after his defeat. He was said to have favored sailing over land travel and to have been the most successful Rapscallion leader.
Damug succeeded him as the Rapscallion leader after he slew his brother Byral. He was also said to have not been able to stand the sight of his son Damug and Damug harbored similar feelings.
