[@Lugubrious] All of them look good except for the Woodland Cabras and Revenant. 

Woodland Cabras:
That is essentially what Orcs do. In fact I may use that description in the Orc Category because it describes them almost to a tee. The others I'll add to the Codex.

Revenant:
Do these demons possess an actual consciousness or do they merely take on an echo of the mind of their host. I have some reservations about this idea but willing to hear more.
