Cavern Orcs, or "Shadow Orcs" as they are commonly known, are so brutal that other orcs fear their ferocity. These grotesque inbred creatures are born deep below the surface, cursed to live a life mining for metals and
forging deadly weapons. The most savage are trained for warfare and eventually make their way to the surface to fight for Arethyr. Gorthokk, a rare strategist among his people, has been chosen to represent Arethyr and to sign the evil pact known as The Covenant of Shadow.
