Casalle (pronounced ca-SALL), given the title Baron Casalle by the sentient trebuchet Lord Mangana, is a construct of Mangana's creation. A sentient swirling mass of swords in a vaguely humanoid shape, Casalle is used by Mangana to aid in his attempted subjugation of the towns of the Western Coast under his court. Of Mangana's three barons, Casalle is the most independently-minded - he has expressed discontent with his role as an enforcer before, though Mangana deconstructs and reconstructs him every time such doubts surface.
