Goffa was a young male ferret in Ferahgo the Assassin's horde. He was supposedly a friend of Ferahgo's son, Klitch, although he denied this to his father. He wore a long blue tunic that had been tailored to fit him.
With Klitch he managed to get inside Salamandastron by pretending to be a friend of Mara and Pikkle Ffolger. Goffa was killed outside of Salamandastron after being struck by a giant arrow fired by Urthstripe the Strong, that was meant for Ferahgo.
