the dark rainbow

rainbow dash is in the forest crying all the way running from her past every single day.  but then she found a place to hide from the bloody trail she left behind.  she could not bare the pure sanity and yet red was all she could see first twilight then spike.  killing every one in her path to be the best.  flutter shy her sister was the easiest of them all she was happy to see her crawl.  rarity and pinkie were a bit of a trance but she killed them all with a stab with no hand.  a forever smile across her face and no blinking forever more.  but then she heard a dark and eerie voice.  ''go to sleep'' (a stab can be heard).  he had never finished her quest now she will never be the best
