The Doctor loved to travel. He loved to see the world. But after losing Amy Pond, he had decided to stop doing that. He lived his new life alone in the TARDIS reading books and occasionally heading to Earth to see if there were new books and other stuff he could do.
The TARDIS, however, can't stand sitting still all the time.
The TARDIS decides to activate herself and transport her away from the sky, taking The Doctor with her.
The Doctor tries to stop the process, not wanting anything to do with the worlds anymore, but gets severely injured and regenerates into an... equine?
The Doctor then finds himself in a strange land called Equestria, a place where ponies speak!!!
Now with the help of Twilight Sparkle and her 5 friends, and a bubbly mailmare, they must conquer many new and dangerous enemies as they haunt the land.
