Sombra wanted revenge on the Galaxianov family, especially Celestia, so he placed a curse on the family. All but Celestia would die within the fortnight. During a siege on the castle, a servant colt helped Celestia and Luna to escape. The girls ran, but Luna couldn't get onto the train. She fell, hitting her head on the cobblestones. Celestia believes she had been the only survivor that night.

An eight-year-old Pegasus filly had been found wandering the streets. She had no idea who she was, or where she was from. The only clue she had was a necklace that read "Together in Maris" and a mysterious scar on her forehead. She was sent to an orphanage, where she was known as Niya.

Now, ten years later, rumors of Luna's survival arise and Celestia offers a large reward to anypony who can bring her sister back. Niya, with the help of two con artist stallions trying to convince her that she is the lost Princess, makes her way to Maris to find whoever gave her the necklace. And Sombra, awakened after all these years, is determined to stop her and put and end to the last of the Galaxianov line. Will the Stallion of Shadow succeed, or will Niya find the family she had always dreamed of?

This story is of no relation to Frozen in a Nightmare, although it features some of the same characters. If you couldn't guess, this is a parody of the movie Anastasia.
