She had tried to dismiss it as coincidence, that she's just learning healthy assertiveness and to not be a doormat. But she couldn't deny it anymore. Her friends told her that she was cured but she knew better. Her recent confidence boost wasn't from practice. It was the instincts of the monster still inside her, inching their way out. She knew this was something that she needed to address before it got out of control. The part that scared her the most was that she was starting to like it.

Many in Princess Luna's night guard fear a mare who is known only by the nickname "Red",for she is one the few ponies who had somehow managed to defeat the almost entire guard without even trying,nopony in the guard was able to learn her real name,so some of them started calling her the Dark Angel or even The Nightingale, and now a new recruit has to be the poor unfortunate soul to see if she even exists...
