Nergal is quite tall with a slim build, black skin, green and purple eyes, a green tongue and green teeth. He wears a sharp black and red suit as well as heeled, black boots. Due to his black skin, his clothes and boots seem to blend in with his skin.Nergal values friendship above all, but his poor social skills, not helped by centuries of isolation, make him an outcast of both worlds. His actions are motivated by jealousy and a fear of abandonment rather than any desire to do harm.
