Hmmmmm.....that could work...of course, there'd need to be a way for her to end up stealing it, which I might have an idea for. Originally, I was going to have her family and her ranch, which was small enough to avoid the eyes of the Parties for a long time, get destroyed by one of the Parties, while she took a horse and escaped, but this gives me another idea. 

What if Erubesco killed most of her family, but captured her alive, since she was still a child and had not yet grown, and was untainted by the Gifted-gene, so they could do some unique testing on her. Once there, she employed the help of a winged bronco, and the two somehow made it out. This would mean the Erubesco is probably after her, and refer to her as her subject number, which is a trope that I've always found awesome. (If that didn't make sense, see Jean Valjean and 24601)
