Then she found a new pack and disided to explore, she found her brother. He scratched her eye and Moon's wings became black and her scratched eye became red.
Later she found out she was blind in that eye.
And her eye turned red along with her wings turning black ment she had a demon/dark side.

If both her eyes turn red, her demon/dark side is in control.
She can harm alot of people and even kill them when she is like this....
