Orcus

Orcus are hooved reptilian mounts used by those who cannot get a better mount or relish a challenge. They are mischievous, playful, and have a mind of their own. Their skin is rubbery and slightly iridescent in a single color (like crow feathers). In the wild their colors only vary in the sheen of iridescence. In captivity more prominent colors have been bred but the iridescence of the colors is dim to nonexistent. The three growths on their backs are similar to an iguana's back spines and are raised and lowered to express their mood.
