My eternal gratitude to my editor, LordOfTheWrongs, without whom Night's Favoured Child would not be the story it is today.

Now with added TVtropes!

This story is a sequel to Into The Depths

The horrors of the catacombs have turned to distant memories for Celestia, Twilight, and Luna. Discord’s change of heart and Twilight’s coronation have helped to ease and erase the mental scars from that harrowing night. The three princesses can even smile and laugh as Nightmare Night moves into full swing.

Yet, it should never be forgotten that those who have been touched by Tirek are forever within his grasp.

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?

There is a secret in Equestria. A secret the newly crowned Princess Twilight Sparkle doesn’t dare to believe. Like puppeteers pulling on marionettes, they have influenced Equestria for better and worse since the fall of Discord. So far they have been benevolent, but their potential for evil is vast. What’s worse, she doesn’t know their name. She doesn’t know their mission. All she knows for certain is one thing.

That they all seem to be zebra.
