Flameless

She was switched out with a changeling when she was very young. When the other changelings decided to throw her to the wolves, literally. The "wolves" took her in and raised her as their own. It turns out that they were magical, and could change to human forms. When in human form, they have a mask that they need to put back on in order to change back. At first they had told Flameless that her mask was lost, but since the others in her pack could control fire even when in human form while she couldn't, she eventually figured out that she was human. Once she found this out, she decided to move into a human town and see how they lived, though she still considers herself to be part of the pack. Her adoptive sister, Pyerre, came with her.
