Angel was born and raised in a very old home, children are often put into this home if they can't find another place for them. When she was there she was already eighteen. Yet stayed, because they needed her. Angel has no memories, nothing at all to go on about her life. Back in the Middle Ages, this was a problem. She was looked down on for her status and being a nobody, but she didn't react. No one could get any reaction out of her and they've tried everything.
After two years of living at the home people noticed she wasn't ageing and her stoic face. Accused of being a witch she ran away with the help of the children. For most of her life she was on the run, until those people passed away, but times changed and she didn't so she had to change her body often. No one really knows who she is, or why each girl vanishes.
As times changed she came to settle into modern life, and over time she realized she didn't hunger for food. She hungered for bodies, men in general or certain ladies with a secret... Angel was born with allure and beauty, attracting people as she went and feeding off them. Being close to her was dangerous, enough to drive everyone mad and her face - it was as if she was an angel.
At the start, she didn't care for being called a witch, and her powers have nothing to do with it... But Angel did take part in witch craft and it was a good option in case something bad happened.
Angel still didn't know what or who she was, nothing ever changed.
