It had been a very nice day. Ponies worked, played and laughed. Wherever you looked all was well. The young pony, recently given the title of 'Princess' was just sitting out enjoying what life had to offer. Then everything changed, and it did so with a cube...

Lost in a plane completely foreign to her, Twilight Sparkle must use her skills as a leader to guide a whole town to safety. Now is the time the young Alicorn must prove her worth as a leader. Over a thousand ponies are lost to an unforgiving, eternally unchanging world. Can she save them all?

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?
