The Elements of Harmony haven't been needed in such a long time and still sit in their place at the Tree of Harmony. It's been many years since Equestria has been at peace. However, Queen Celestia and Luna have taken notice of things yet to come and have debated every option they could take. Tirek was brought up and Celestia decided that trying to reform him would be the best option they would have. The risk was heavy, but it was a risk they needed to take.

Based on my own Next Gen characters
Keep in mind this is how Celestia and Luna look like in this AU
Next Gen Queens

2540 years before Nightmare Moon returned from her banishment, centuries before both unicorns and pegasi came into existence, and nearly a millennia and a half before the two sisters would even be born; it was the year 2549 of Emperor Grogar the Immortal’s reign.

For over two and a half millennia Grogar had reigned as the undisputed emperor of Equestria with an iron hoof. Millenia of killing the treacherous and rewarding the loyal has left the government filled with yes men and the population was kept in line with fear of the God that ruled their lands. None dared to question his rule but the land was at peace.

Yet now of all times, the seemingly untouchable God like Emperor of All will be killed in his sleep. What fate awaits Equestria when the pillar of all society, government, and even religion is suddenly killed…

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?

Twilight Sparkle failed her entrance exam, and the consequences were far more deadly than anypony could've predicted.

Where many ponies would see this as a terrible tragedy, a creature only spoken of in the darkest of legends sees the poor filly's fate as an opportunity...
