She has mixed heritage; a little bit of fiend, some dragon blood, and some human. As to how she ever came to be, well, that's what she's always wandered. Even though a fiend's blood runs through her veins she still tends to lean towards good, but usually walks the find line of neutrality. Past that she's a loner and tries not to associate with the rest of society as they tend to reject her. Ya know, claws, fangs, wings, and all that.
