Ruffgar Brookback
Ruffgar Brookback, also known as Ruff, was a male otter native to Mossflower Woods. He described himself as "Ruff by name, rough by nature". He encountered Lord Brocktree and Dotti on their way to Salamandastron, and was attacked by Brocktree when mistaken for an enemy. After the encounter, Ruffgar joined their quest to liberate (or at the time simply journey to) Salamandastron. He gave good advice to Dotti in her competition against Bucko Bigbones and was one of the party who helped Dotti enforce her diet, weathering her tirades against him.
Ruffgar was a good cook and learned one of his recipes from his grandmother. He fought loyally at Brocktree's side, and even saved the Badger Lord's life by slaying Doomeye. When the battle was over, Ruffgar joined Skipper of Otters Brogalaw on his journey back to his home.
