Shortly after the discovery of Hollow Earth, he tried contact the "ghost ship" in order to buy a number of Abnormal slaves. Sioux, one of his deputies, desperately wanted to keep him from making that deal, even being willing to kill him with a jessoped but because he was an Abnormal it killed him slowly.
