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?

This is an alternate universe wherein Rainbow Dash is the Element of magic, and the lives of herself and her friends have been changed, along with their respective elements. However, despite being the Element of Magic, Rainbow Dash isn't Celestia's student....that title belongs to her childhood rival, Sunset Shimmer.

Is now the first story in the Rainbow is Magic verse!
