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?

Celestia is struggling to come to terms with her true feelings for Twilight.

Unwilling to watch her sister suffer under apathy and indecision, Luna takes it upon herself to help Celestia confront her newfound feelings.

Twilight has something she needs to tell Princess Celestia--something that means a chance at getting everything she's ever wanted, or of losing everything she's ever had.

Something so terrifying that the only way she could say it was in a letter...and so wonderful that she had the courage to send it.

Celestia leaves to deal with a foreign crisis, giving her sister a chance to rule alone and become more attached to the modern world. She calls on Twilight Sparkle to advise Luna, hoping her student will be able to draw Luna out of her shell. With two major threats to Equestria already defeated in the past year, it seems like the perfect time to let Luna gain some confidence and experience in the modern world. After all, what are the chances of a third disaster occurring?

Now comes with complimentary tropes.

Sometimes, fiction matters.

Now with a Spanish translation by Spaniard Kiwi!

To commemorate the imprisoning of Discord one year ago, the first annual Celebration of Harmony is starting off with a grand party in Canterlot, something Twilight Sparkle has been looking forward to after many sleepless nights plagued by nightmares. After a chance glance at the party, Twilight and Princess Luna rekindle their friendship sparked on Nightmare Night. Meanwhile, Princess Celestia grows worried over the state of her kingdom, her sister disappearing at odd times, and the seal placed on Discord. Are the princess's worries well founded or is her sister's oddly secretive behavior taking a toll on her nerves? Twilight gets caught between the sun and moon as both royal ponies reveal that there is much that history has forgotten about the nature of the alicorns and even the draconequus.

AU for not taking into account Season 3 canon.

Twilight just wants to sleep; unfortunately for her, not only is Celestia in a playful mood, but Luna is itching for some quality time. Shining Armor and Cadence then show up, and it turns into tug of war with Twilight as the rope. The prize? Spending quality time with everypony's favorite purple alicorn.

This story has Twilight/Celestia and implied Twilight/Luna. Also, Cadence has a very... vivid imagination.

Now a plotless(okay, so there's a bit of plot. Just a smidge, though.) ball of comedic fluff with multiple chapters.

Chapter 1 - Say It - edited by ultra1437

Luna and Twilight are sunk into a fractured, feudal world, where the knowledge of magic is lost. Penniless and depleted, they're forced into playing by other ponies' rules, all the while trying to discover even where home is.

This is the story of the end. This is the story of the death of Equestria. It is the story of the reign of her royal majesty, Princess Twilight Sparkle of the Fading Sun.

The alicorn sisters are dead and Equestria has turned to Twilight Sparkle to guide it. However, just maintaining a dim sun a fraction as bright as her mentor's keeps the new princess near her limits.

Years have passed and Twilight Sparkle is sure of only one thing. Equestria is dying.

NOTE: Written before "It's about Time" in season 2. Everything after "Read it and Weep" was ignored throughout this story.

What if Twilight was orphaned before her acceptance into Celestia's school for gifted unicorns?
what if she and the princess of the sun became inseparable? What if Twilight starts calling Celestia mommy after their lessons?
What if Celestia loves it?
