All right, I have a few other ideas there, and it basically comes down to what kind of story you want to tell. Frankly, Rei could do just about anything you want her to with her background. She could do anything from waiting tables at an inn to leading a whole country. I'm leaning more towards her being some sort of rogue leader or something, because come on, "Void Queen" just sounds so badass. Or maybe she's a priestess who tries to hide her true nature from those who hate Voidspawn? Just an idea.
