Yeah, probably about one in one.

There comes a time when the light must go out; but how do you know if you've burned brightly enough?

Speak no evil, only breathe. Hear no evil, only listen. See no evil, only darkness... or so the tale goes.

There is a reason.

Currently undergoing editing by the wonderful Mstar!

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?

Princess Celestia writes a report to her teacher on what she has learned about mortality.

Audiobook by Scribbler!

For most foals, a magical surge results in a couple hours of frantic searching. For Twilight Sparkle, a magical surge vaporised an entire Canterlot block and killed hundreds. Having spent the last ten years as a fugitive running from the law, she is tired of her life and all she desires is for the nightmare to end. With one last night before she turns herself in, she spends it with her one and only friend - Trixie.

Welcome to the new Equestria, Twilight Sparkle. See your friends at each other's throats? You have to choose between them now, to stop the heartache of war with decisive victory. For the nation lies bleeding, its harmony shattered into a million pieces. Black and white and right and wrong have blurred together.

You must choose wisely, or all shall die.
