Sean Ratcliff (Rat) is a character introduced in The Gorgon's Gaze. He was introduced into the Society in Mines of the Minotaur, as a companion to the Frost Wolf. His companion is a wolf named Icefen, and his mentor is Erik Ulvsen, a cousin of Clive Masterson. Rat greatly disregards the rules, and criticism seems to simply bounce off him. As Col once said, "Yeah, Rat, not everyone has the sensitivity of a stone like you do."
