After Twilight and her friends rediscover Starswirl’s last spell in the ruins of Golden Oaks Library Rainbow Dash asks, ‘why can’t we all become alicorns?’ Now Ponyville is host to five brand new alicorns and the girls have everything they could ever want; magic, flight, power, influence and all of Equestria wide-open before them... but being a Princess is far more than just having wings and a horn.

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

Insert title. Add a dash of timing and miscommunication, maybe a sparkle of innuendo. Oops, almost forgot the kitchen sink. Seriously though, the mane 6 help Dash deal with, and find a cure for, her sudden um... change.
