Equestria has fallen, three of the deadliest villains to ever ravage the world have taken control, Tirek, Chrysalis and King Sombra have divided the country between them and the ponies are now nothing more than slaves to their command. Her heroes fell from grace and her princesses disappeared and there has been no news of them for centuries.

For 1,000 years, the world has been in chaos and destruction, and all this time, a lonely mare has been trying to get away from her past. But as history has shown hundreds of times, you can never escape your past forever.

Old Mare Celestia.
