I have a penchant for playing characters that don't fall into either catagory as far as good vs evil dark vs light which is why I love that humans in this lore are the in between characters. Although I deffinantly want him to feel like a real Warlock so you will deffinantly have an evil slant but I'd like to juxtapose that with being purely Human. Also when I was reading the lore it says that humans didn't have access to magic until later on in history (with some exceptions correct me if I'm wrong). as far as the time line goes how new is magic to the human populace in terms of years from when it became a more normal thing
