Jacob Carpen is the resident villain of Minnakht. He is the older brother of Martin Carpen.
Jacob Carpen is a brutish, large man without much intelligence. His other brother Matthew Carpen does most of the thinking, while Jacob's role is in fact unknown. He owns a large army of genetically improved, possibly cloned soldiers, and a mansion somewhere on Florida, imbued with advanced nanotechnology, letting it rebuild itself when needed.
His first appearance is marked as soon as FAW II, but he never had much significance.
