Pinkie has a horrible secret; she's a changeling. She has been for a while.

But she can't bring herself to tell anyone or anything, except a cheap journal. It's better if nopony knows, after all, and her lies aren't hurting anyone.

Not hurting anyone at all...

Notes: CH 1 edited by Sessaslisk.

Conjuration is a lost art in Equestria. Celestia is bored, and decides to learn some summoning spells. She summons an otherworldy creature, but will it be anything like what she expects? A non adventurous HiE. Mostly just learning about interactions. I'm just gonna roll with it, and add tags an ratings as the story unfolds.

Luna has been plagued with vivid dreams of Nightmare Moon, and from what she's encountered, she doesn't know who to believe anymore. Is this the same evil mare she had become? Or just a misunderstood pony looking for love? Now Luna must decide: friend or foe?

Super special thanks to my editor SpaceCommie

Though the distance between Pinkie Pie and her five closest friends has grown in the half-century since they claimed their Elements, she does what she can to prevent the others from drifting away. It’s small things, mostly: tea with Rarity, a drink with Rainbow Dash, a few words with each of the others. The friendship still makes each day together magic, and she works as hard as ever to bring cheer to all of her friends. When the smiles come less frequently, that just makes each one that much more precious.

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 was only one explanation. For all of it. All of the strange, erratic behavior. Her irrational fear of the sun. Her nocturnal habits of locking herself in in the dark and closing all the blinds. Wearing her sunglasses everywhere, even inside! It was time to invest in some silver, garlic, and a wooden stake.

As Twilight Sparkle awoke one morning from uneasy dreams, she found she had been turned into a changeling.

How has she become a changeling? How will she adapt? How will her friends respond? And what new terrors will her metamorphosis bring?

Thanks for everything guys. I never expected this thing to get so popular. I need to rework the second chapter, but it looks like there's going to be a blue moon every Friday for a while yet. Thanks again for your support and please keep reading and reviewing!

EDIT2: I've updated the character list again, a little preview of the second story arc...

EDIT 3: Just doing a quick character update to account for changes made to the next Arc...

After being banished by her sister, Luna is frustrated with her fate. It's a shame that there's no one on the moon she has to take her anger out on...

... Or is there?

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!

As Discord finds himself in the darkness of his own mind, Celestia visits him momentarily to leave the creature with a memory of when the two were children.
