Caelus is a half-incubus raised to believe that the world would, and should, bend to his will. Mostly his will is to be overpaid for his consulting work.
Capable of feeding on darker emotions in addition to lust, Caelus has discovered a particular taste for humiliation and fear -- especially when paired with desire.
Background
A half-incubus raised mostly by his human father, Caelus was taught to believe that world would -- and should -- bend to his will. His Succubus mother wasn't interested in parenting, but she did shift the occasional lever of power in his favor. Caelus attended the best schools, took the choicest internships, and accumulated a truly impressive resume before he graduated college -- at which point he was on his own. He built himself a small consulting firm, and like all good consultants is always a little vague about what exactly he does. Something to do with workflow optimization?
