Celestia and Luna were born as unassuming foals in troubled times. But already marked for greatness, the simple earth ponies stand to face a world set against them, full of danger, fear, and sadness. A world they will change forever.

A sweeping epic taking place before Equestria was made, where Celestia and Luna must rise from normal foals to become the Princesses we know them as, beset from all sides by monsters, other ponies, and even the forces that govern nature. Their tale is as tragic as it is triumphant.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.
