In the Game
Maddox is a crazed Conqueror who has kidnapped Talon, leading Worthy and the Keeper to him. In the final underground quest, Maddox fights the Keeper while summoning more and more spirit animals to his aid; three of them were snakes, armadillos, and bears. When he is defeated, he warns the Keeper about The Wyrm and disappears. He also had a spiral mark on his forehead, similar to Zerif's.
