One night, during a freak storm, a dark stallion wonders out of the evergreen forest and collapses outside Fluttershy's cottage. But after being treated in the infirmary, he is found to have no memory or any recollection of his past life. What no pony knew was that a monstrous army was forming with a goal of destroying all creatures of chaos, along with ending the Alicorns rule and inslaving the populace of equestria. Can the lives of all ponies rely on the beasts they once aimed to destroy and warriors long thought to be myths?
