Castanea is one of the Generals of the Conqueror's army, said to come from a small village called Veyriel. He is never seen without Roeas at his side. He is a rather tall man, being almost half the size of the Cyclops. He wears a helmet with long jagged horns, and uses a large hammer for a weapon. He is actually a Mitra although of unknown origin. He bears striking resemblance to the Colossus family.
He never speaks in the game, in fact, the only dialogue he ever gives is angry grunts, or roars.
