Is There Magic in Niko?

Niko has always been drawn aesthetically to very witchy goth stuff. I've never liked it when o is written as all knowing and powerful, because i don't know where that confidence comes from. She's only over 16 to 18 in any of the books, so it doesn't seem to me that she should be confident. So definitely, the way that i wrote niko was someone who has a lot of personal confidence and is resourceful,. But is always on the edge of out of control, because she has so much power.
