Xerxes is the familiar of the sorcerer, Mozenrath. He is a floating eel/lamprey-like creature, who speaks in broken English. Xerxies is endlessly loyal to his master, though he has the habit of saying the wrong thing and taking a beating for it. And yet despite the abuse he gets from Mozenrath, Xerxes remains faithful to his boss. He can also be even as sadistic as Mozenrath. His name is the name of a Persian prince who attacked Greece 10 years after the Battle of Marathon.
