We all know the story of how the Princess’ young student and five friends defeated Nightmare Moon and brought Princess Luna back to our lands. But what if the tale were false? What if the young Twilight Sparkle on the event of her entrance exam had not been rescued by Princess Celestia, but instead lost her mind among the power of her youthful surge and had to be sent away, far away before she could destroy all of Canterlot with her newfound power. Now the feral unicorn prowling the Everfree Forest only vaguely remembers her past, slipping away from constant terrifying attempts to capture her.

And she is beginning to remember what true power felt like.

Sequel: Left Behind: Sunny Disposition
Apparently it was scouted and is on EqD too

Nightmare Moon was meant to be released after a thousand years. A momentous occasion for her but terrifying for all the ponies on her day of freedom. She would get revenge on her sister and cover the world in darkness and shape everything to fit it.

That was the plan, at least. Instead, something went awry with the spell and she wasn't released when she was supposed to be. The mare-in-the-moon is brought into a world with stagnated technology, giant cities, and no sign of her sister or any of the other immortals. In fact, ponies don't seem terrified of her at all, and the stay within the core of her powers infused and changed the alicorn's body drastically.

The alicorn had no obstacles left! But...she was also a relic of the past. A past everyone seemed to have forgotten. A past she could no longer look upon.

Big thanks to Kryostase for helping spot errors I've missed.

A science fiction story about how a fantasy world came to be. An alicorn foal awakens alone in a world that sentient life has long since left behind. This story follows Luna through her foalhood in the strange world, her quest for knowledge about who and what she is, and what happens when she finally finds her answers and makes the trip to the beautiful new world that her sister now rules.

Author's note: This was my first story, and even though it's complete now, feedback is still very much appreciated. My biggest goal here is to continuously improve, so every two cents helps.

This story is a sequel to Imperial Affairs

A thousand years ago, a War has started. The War that just found a resolution. With Princess Celestia accepting defeat and her new place at the court, and the new Empress forming a reluctant understanding with the Element Bearers; the time has come to move on. Nightmare Moon found herself on the top of the world with no enemies remaining. Ponies reluctantly accept their new leadership, Princess Luna still has a legitimate claim. Little do they know, for their beloved Princess long since ceased having a word on what goes in the court.

Also, go ahead and check out my editor, MLE. She's awesome and worthy your time, I promise. Don't forget about The_Darker_Fonts too, both help a lot.

Cover by the wonderfully generous Hypocritic Oath.

After Luna had been banished to the moon, Celestia got drunk, real drunk. Drunk enough to make up several laws she completely forgot about for a thousand years. What happens when Luna discovers one of these laws, and what's worse, she actually likes the sound of it.

Complete chaos as the mane six now find themselves unintentionally being wed to two Princesses.

There is a sequel to this story: Sequel Here

Very much inspired by the old: Six Brides for Two Sisters story by Equus Palladus.

A Big Thanks to ArcaneDust for proof reading.

Discord has one friend. One. A single tie binding him to Equestria, a lone strand of pink tail hair keeping him in some sort of line. His interest in the world's welfare may exactly equal that of his friend's lifespan -- unless there's a next generation for him to adore. And so in the name of the realm's survival, Fluttershy is going to start dating, with Equestria's greatest expert in attracting ponies as her very reluctant prison-sentenced advisor. All Fleur has to do if she ever wants to come home again is get the world's most socially hesitant pony happily married off and pregnant, while constantly keeping Discord in the dark about what's truly happening.

What could possibly go wrong?

Flurry Heart wants to know what happened to the Crystal Empire's previous rulers. Cadance answers with as little detail as possible, and unintentionally teaches her daughter about a tradition she wasn't aware of.

Entry for the Cadance is a Terrible Mom contest, and 1st place winner! Admittedly an idea I've had in my head for a while, thanks for the excuse to write it!

Luna becomes the Princess of Detention. It's not because she was naughty. Stuck atop her lofty tower, it is up to her captives to save her from herself.

If only she didn't write her own demerits.

Now part of a trilogy. Because these things happen. Next up in the series is The Foundling, and this will be followed up with Princess Luna & the Curious Case of the Bitch Fish.

Clover the Clever never asked for his life to get so complicated.  It was bad enough tricking a drunk Imperatrix Celestia, war goddess of the Three Tribes, out of her accidental coup against Queen Platinum.  But now the most dangerous pony in Equestria has returned to trade her claim on the sun for a chance to woo him.

On top of that, his erstwhile mentor Star Swirl the Bearded has saddled him with a mysterious magical necklace and a uniquely bleak and pointless prophecy: If he's brave enough, and if he's clever enough, he just might survive Celestia for long enough to break her heart.

Now with an audio reading by ScarlettBlade!

Recommended by PresentPerfect! "horizon gave me the story I needed rather than the one I wanted ... along the way we get some very strong lessons about love, and meditations on the value of a lifetime and what one pony can achieve on their own."

"Between the time when the oceans drank Marelantis and the rise of the Elements of Harmony there was an age undreamed of.  And unto this Celestia!  Destined to bear the jewelled crown of Equestria upon a troubled brow.  It is I, her chronicler, who alone can tell thee of her saga. Let me tell you of the days of high adventure!"

Celestia is many things to her little ponies: princess, leader, and teacher, to name a few.  Yet her past is unknown to her subjects, lost to the depths of time.  After she passes her crown to her student she descends into a place unvisited for over a thousand years, and there remembers a time before the Magic of Friendship, before Equestria, and before the Elements of Harmony -- the Hyponian Age.

It was an era of cruelty, violence, and hope.  Into this harsh world, Celestia the Cimmareian ventured out alone in search of gold, glory, and adventure.  The Tower of the Fallen Star and the horrors within await.
