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 story is a sequel to Past Sins

When pursuing Starlight, Twilight and Spike experienced variances of Equestria, and saw how the river of time could have been different. Now, Starlight has moved in with Twilight, Nyx, and Spike and has begun her studies in friendship. To thank those who have helped her embrace friendship once more, Starlight has created an enchantment that allows the castle’s map table to let anyone glimpse other variances of reality.

The power to ask “what if,” can be a source of great amusement… but for some, the hypotheticals are haunting reminders of what could have been.
