Epitaphe is the result of a failed experiment performed by a school of mages who's only goal was to create a catalyst to study demonology. And we all know that sort of practice never goes wrong. Suffice to say, no one but Epitaphe knows what happened to those mages.
He speaks in third person and is adorned in numerous markings across his body, predominantly his face, arms, and stomach (right now you can only see his right arm. Another image will detail his left arm). Each set of markings catalyzes a different form of magic, and his stomach actually opens and functions as a second, larger mouth with no teeth.
So, uh, say hello to my demon character that's not Mephistophelian. Inspired by a certain infamous demon fella and Dusknoir. Done by OminousWiky
