Celestia and Luna decide to settle one of their little disputes by switching bodies for a day. Heaven knows what will go wrong.

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?

Well it's not actually a sequel. Here is a collection of short stories and histories detailing the life of Alternia, a changeling queen impersonating the life of Princess Celestia. These are the stories of the ruler under her mask.

Reading the main story: Princess Celestia: The Changeling Queen is a requirement if you don't want to be spoiled or confused. I will try to provide background information when I can.

For readers of the main story, there are basically no spoilers if you've read past chapter 8. Enjoy!

Update: The story is edited into a proper read without many of the horrors I originally put into it. Enjoy the ride!

Deciding he could be given another chance, Luna and Celestia come to an agreement to release the Chaotic God from his rocky imprisonment, locking his powers with a powerful spell. Magicless and with a chance at redemption, Discord's ways seem less chaotic than ever.

He does cause a lot of chaos though, to the faithful student of Celestia, who had eagerly taken over the task of watching over and teaching Discord by giving him a home under her own roof, in the process hoping to learn more about his species, powers and motives but surprisingly learning much more about both himself and her head... Which puts her in pretty amusing situations most of the time.

An adventure of a silly one sided (???) love and a look into the heart of Twilight Sparkle.

...The Continuum feels this species may be a real threat to the Q. However, they also show a unique ability to contain their power. They do not appear to use their abilities for power, greed, or war. We need to see if the species as a people are a threat to the Continuum and not just their abilities.”

“And locking me away in a statue, to rot away in a garden, doesn’t show that?” The face on the statue squirmed and struggled to free the rest of its body.

“No. It doesn’t,” said Q. “But it would seem an opportunity has presented itself. The Enterprise is heading for this region of space. Perhaps you could utilize their presence to…provoke…a situation?”

Both Q started grinning together. “Oh you know me too well, Q. I always enjoy seeing my favorite starship captain.”

The blond Q reanimated the rest of the statue. Discord stepped off the pedestal onto the soft grass. “This is going to be so much fun,” said Discord as his shape began to contort and transform. Within moments a familiar figure in a Starfleet uniform was standing where Discord had been a moment before. As the pair started walking away the blond Q said, “Just remember, Q. This isn’t just some random species to be toyed with. Any species RELATED to the Q, can KILL the Q!”...

Stargazing. Nowadays it's a great pasttime. Thousands of years ago? Not so much.

And Luna doesn't like that.

Amazing what my muse comes up with on the fly.

Enjoy.

Once upon a time, in the magical land of Equestria...

One week ago, Twilight Sparkle was crowned the fourth Princess of Equestria. Tonight, Ponyville hosts the 1003rd Summer Sun Celebration, and Princess Celestia and Princess Luna want a vacation. With two fine young princesses like Cadance and Twilight to take over for them, nothing could possibly go wrong.

It is the responsibility of a king to care for his people and maintain order in his kingdom. That shouldn't be much trouble for a ruler as powerful as Discord, right? With his faithful and insecure advisor at his side, the draconequus sets out to explore his new world and personally see to it that peace reigns in Equestria.

However, the ponies want nothing to do with their frightening new ruler, and the unamused Spirits of Equestria aim to drag the Spirit of Chaos away before he can cause any more harm. Can Discord be the ruler Equestria needs? Or is he truly doomed to become the monster he is seen to be?

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?

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 Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.
