In my first novel the protagonist is Shadow Delaney. He lives in a world where demons outnumber humans. They're segregated in most places. The demons are getting more privileges than the humans. (Better hospitals, schools, restaurants, etc.) Most humans don't think too highly of demons, and vice versa. But, Shadow wants to major in demonology and he's absolutely fascinated by them. What was once a demon only university finally opens its doors to human students. He's the first human to attend it.
Even though I already published this first novel, the real 'antagonist' doesn't have a name. A lot of my other characters have seemed 'evil', but really were just misunderstood. This guy seems different. He always seems to have a female assassin next to him. He loves to watch from the shadows, and do things without really being noticed. I've hinted that he's a 'Dark Healer'. In that world they are kind of the criminals of the underworld, tricksters, love to control people, and 'pollute' the mind. They tend to have 'dark' features, as well. (Most are really just misunderstood.) The opposite of them are Light Healers. They're kind of the police of the underworld, heal demons and humans (although they aren't as skilled with humans), educate, have special powers, etc. They have 'light' features. Anyways, he seems to know about Shadow specifically. He's been behind many 'incidents' in the story. No one, including the people who work for him, knows what he's really planning. I might make a sequel in the future, and might feature him a bit more. He's really creepy at the moment, though.
