A quick drawing I did a while ago with another character I might use in a D&D game, this boy here is a Cor'Gisir, a corgi from the Feywild, he's a magical pupper.
Occultists brings forth dark powers for strength and other magical capabilities.
That doesn't make him evil though as he really wants to help people in the best way he can, even if he has to work for a Fey Liege of darkness.
