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 choleric demons that look like large, fly-like monsters with tattered wings. Their heads are insectoid, with great compound eyes and dripping mouthparts. They spread clouds of disease behind them as they pass, reveling in squalor and favoring kings who use plague as a weapon of war and assassins who kill with poison. They attempt to goad mortals into doing all of these things, and they themselves spread plague as well, leaving disease in their wake wherever they go.
Choleric demon-kin spawned from the minions of Utarviz have dark, multi-faceted eyes; tattered insect wings; and favor using poison and disease to destroy their enemies.
