Nimrak the Deathly is the evil bilge rat warlord and the primary antagonist of the first book of Legend of Tyvan. He captures Tyvan. He is later backstabbed by Skyvar and loses his sanity. He slays most of his crew, except for Leif, over the course of the book. He is slain by Scarface, but gets back at him when ressurected by a potion. Revived as Karmin, he follows Tyvan. He ends up killing the squirrel Feather, but has a knife thrown into him by his own kill before he dies. Karmin falls into the water and is ended for good by Arrowhead.
