Addison was given up by her mother in a series of supernatural deals. She grew up not with one strange parent, but 3 demons, a faerie queen, and an old witch. Growing restless as she grows older, Addison searches for a way to choose her own path, and come into the powers of one realm instead of stuck between all three.

So the faerie queen makes her a deal. Go on a quest, and earn your freedom. All she has to do is find the three things that bind her to each place.

Now shes on a mission. Figure out what those are, and get them back to the fey realm.
