Mithas is a scion of House Deneith, though he does not bear the dragonmark. He is a sorcerer, and is very ambitious. He holds a moderately high rank within the command of the Blademarks Guild. He was once the lieutenant under Robrand d'Deneith, but was later replaced by Singe. He holds a grudge to this day, and when given the opportunity he interferes in Singe's affairs. He also uncovered the fact that Ashi d'Deneith bears the Siberys Mark of House Deneith, and later chased her and her companions through the streets of Sharn.
