Dark Mist was a normal pony, was being the appropriate response, but when he sees his father kill his mother along with his brother? He left that house to never see it again. It has been only a month and he is slowly going insane. He discovered Ponyville and has taken residence there. But one day he snaps and Twilight must find out who has been murdering everypony.

This came to me after reading some stories and my psychotic part of my brain twisted them hope you enjoy.
