Twilight had always been fascinated by the idea that there were other worlds beyond that of Equestria. This has lead to her getting approval from Celestia to experiment with the mirror to see just what lies behind the glass. Unfortunately, the best laid plans always seem to go wrong for her.

Now, after waking up in strange forested mountains, she finds that she is in a world much different from the world of Canterlot High. With the aid of some of the local citizens, Twilight must now learn to adapt and maybe explore this rough and rugged world she has landed in.

(Takes place just after the first Equestria Girls)
