Demihumans are viscous and wild outcasts of the world, living on the fringes of civilization and the ruins of forgotten times. They are basically beastmen and mongrelfolk, humanoids that combine the degenerate forms and abilities of animals into a ferocious bestial form.
They are usually the descendants of failed and twisted magical experiments from previous civilizations. They gather in tribes or clans of creatures with similar characteristics, although their tainted lineage means any form could rise in any location.
