When it comes to magic, Kris is a junkie. She wants all she can get. And that is bad for her.
She’s grown up with a warning from her grandmother -- abuse of power runs in her family. And she’s never said it to her grandmother, but she knows that it’s something along those lines that killed her parents. But for some reason, she’s never able to control herself. She’s always wanting more. It’s dangerous, and she knows that, but Kris spends a lot of time reading DARK MAGIC books. She feeds off the power she can get from them, and there are moments when she loses control of herself and the power takes over. It’s something that she makes an effort to keep from happening in front of others, particularly her grandmother, but everyone slips up from time to time.
