Utarviz, demon Lord of Plague, takes the form of a giant fly or a man with tattered fly wings and fly-like features hidden beneath a cowl. A wake of putrid decay follows him wherever he travels.
His are the souls of those claimed by plague who were not accepted into a more pleasant afterlife. The grotesquely unclean, kings who use plague rats as weapons of war, and assassins who kill with poison also belong to Utarviz.
His followers are the Morbai, fly-demons who spread plague in their wake.
