Uxas The Mad

Valdarius last and forgotten apprentice, son of the mongol sorcerer Yuga Khan, he carried the curse of his ancestors in his blood. In his unrelenting quest for power, he balked at nothing, even distorting his own body past all semblance of humanity, or accepting the aid of demons.
He is the creator and sole user of the Summon the Inner Weapon initiation script, which left himself saddled with a demonic black sword. He didn't care.
