Nightmare Moon has returned. Princess Celestia lied and betrayed her star pupil, Twilight Sparkle, leaving her woefully unprepared to fight the Queen of the Night.

But when she fails, rather than disposing of her and the ponies that tried to help her, Nightmare Moon sees an opportunity and a necessity. Having been locked away for one thousand years, who better to help her solidify her rule and keep Equestria from collapsing, all while rubbing it in her sister's face, than her own betrayed pupil?

Twilight was always fated to be the savior of Equestria, along with her friends. But fate can be so easily altered. What happens in one alternate realm when instead of marrying a unicorn, Twilight's mother had instead married an earth pony, resulting in her daughter being hornless? Without her magic, Twilight's future and destiny are far less certain, as is the destiny of all of Equestria.

However, destiny is not so easily set off course. When the princess of the night returns, can one little earth pony hope to be the one to help her damaged heart?
