Calix is the blocky Count of the Feverthorn Border, in service to the High Lord of Rhodes. He headed up an illegal slaving operation a few years before Furies of Calderon—an operation that Fidelias broke up. Subsequently, Calix was forced to spend a great deal of money and trouble covering his tracks. Shorty before Furies of Calderon, Calix was sent by Rhodes to work in Aquitaine’s employ, and to assassinate Attis come the time.
Furies of Calderon
Fidelias exposed Calix’s true colors to Aquitaine, which resulted in Calix’s death at the hands of Aldrick ex Gladius.
