With the time she has left, Rainbow Dash seeks what is truly important in life before moving on.

Not all scars are visible. Fluttershy was the object of countless jokes and taunts aimed at her aerial ineptitude and her close relationship with Rainbow Dash during flight school. Even now, years removed from the fillyhood traumas of her past, Ponyville's resident animal expert feels the effects. She tried to build walls to keep all of the memories at bay, but now those walls are a little too close for comfort.

No one expects to go to sleep and never wake up. There's always tomorrow, or the next day. There was always time. So, when a young life is extinguished before its time, it becomes especially difficult to handle. When the spirit of that life is forced to face and accept her death, what will become of her afterlife? Scootaloo will soon be faced with this tragedy, and this is her story.

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?
