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...
