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?

The Well of Eternity a place lost to time, is the birthplace of Equestria's various deities. King, a mortal man from Earth slips between the cracks that separate worlds. Landing in the unforgiving badlands of greater Equestria, he aimlessly wanders through the unforgiving terrain. Eventually enslaved by diamond dogs, for ten long years he labors under their cruel whips, eventually escaping his captors only to become lost in the depths of Equestria's vast underworld. Dying of thirst, the man spies the Well of Eternity and drinks his fill. Its waters more than quench his thirst; a metamorphosis occurs and changes him, for good or ill none can tell. What fate shall befall this man, the Great Slave King?

For almost a thousand years, the immortal Nightmare Moon has reigned over Equestria as Empress. To the average pony, Nightmare Moon is an overarching enigma whose rule is absolute and whose wrath is terrible. But to Twilight Sparkle, who as an orphan has never known her parents, the Empress is something else entirely. When the young unicorn is brought under the royal wing as an apprentice, she learns a great deal more about the supposed tyrant than she ever knew. But as Twilight is introduced to life with her new mentor, she is thrust into a world of political intrigue, conspiracies and secrets. Secrets that were never meant to be revealed. As allies and enemies plot against the very peace of the nation, will Twilight fall prey to the perils of her new position? Or will she prosper and find in Nightmare Moon the mother she never had?
