The Lunar Rebellion sought to bring Nightmare Moon to power over Equestria, and for two long years, a war was fought for that very purpose. In the end, Nightmare Moon was defeated, but Celestia had become broken. She lost her faith in the ponies that once only knew love, and she walled herself inside her castle at Canterlot.
For five years, no pony had seen or heard from the goddess. In her absence, Equestria falls apart at the seams. Endless skirmishes are fought over petty land disputes. Love and tolerance are gone from the land. Ponies begin to revel in the art of war. When a dangerous threat emerges from the ashes of the Lunar Rebellion, all hope seems gone from the world. But some ponies aren't willing to let Equestria fall.
Four unlikely ponies step up to correct the mistakes of the past. In their quest to restore Equestria, they will learn that through the magic of friendship, all things are possible.
