What would life be like if all of Equestria's villans roamed free? If Nightmare Moon defeated Celestia, Sombra ruled the Crystal Empire, and changelings were a daily threat. Oh, and Discord wasn't a statue. When an unknown evil threatens the Princess and kidnaps the Queen, all of the Princess's friends must rise to help her save the kingdom.

Sex tag for some suggestive dialogue.

Other tag stands for: The rest of the Main 6, Celestia, , Cadence, Soarin, Chrysalis, Discord, Changelings, and maybe the CMC

If I copied some other story, I am very sorry. Please notify me.

Twilight Sparkle is called to Canterlot Castle where something has happened to Princess Luna that has reverted her to a weakened state, she has to live with Twilight whilst she recuperates her magic.

Princess Luna's Lunar Stallions kidnap Twilight Sparkle when they see how lonely Luna is, and give her to the Princess as a gift. Nightmare Moon emerges from Princess Luna's psyche during the sleepover. The dark goddess would love nothing more than to have the beautiful mare all to herself, and the resulting chaos forces Celestia to call a psychologist to sort out Luna's multiple personalities.
