Peryite

Peryite is a Daedric prince who often appears as a fourlegged dragon and is also known as the "Taskmaster". Considered as the weakest of the daedric princes, who's spheres are order and pestilence, his nature is more of a destructive kind and he takes a liking for blessing his worshippers with diseases. His enemies in the daedric pantheon are Vaermina and Mephala.
