She has long since dismissed her original objective, forgetting exactly why she is stuck in this alternate timeline in the first place. Her only mission now is to stop the mare in her way— an adversary with uncanny magical strength and indefatigable purpose.

It’s time to finish this... once and for 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?

Former King of the Crystal Empire Sombra wakes up in a cell with the given decision between reformation or a lifetime in prison. He accepts with some caution and after some details are sorted out, he is moved to the castle of Princess Twilight Sparkle under reformation.
With all the craziness about the arrival of an evil slave king going through the humble town of Ponyville, Sombra is left wondering what he got himself into.
Can two ponies who hate each other with all their guts become friends and prove that old habits can be changed? It depends on how you define 'hate'...

UPDATE: Under... construction perhaps? It has been years but... maybe I'll update this. After I rewrite every chapter, of course.

She can swim far and wide across the waters of Equestria, but it's not enough. There are places above those waters, places she plans to reach. Where biology failed her, her mind would succeed. Equestria better be ready, because she plans to visit!

Or is it the hiding place for something much more sinister?
