Matred

She always believed that she was different from everyone else. She never realized how different she was but she always had a feeling. When her family dies in an extreme tragedy she faces dark consequences. She can either die, and become a demon like her family, or she can go to Matred to train to battle Lucifer when she becomes twenty one. She's eighteen now and Lucifer has a plan. He decided he was going to change her anyway, but for some reason during the transformation something happened to her. She stopped changing half way and now she has to not only learn and control her abilities, but then go against her new half father. Lucifer.
