It shouldn't have been a big deal. Celestia was kidnapped or knocked out or just generally made to seem powerless by whatever idiot with ill intent decided to show up on a nearly weekly basis. As the mighty and immortal Sun Princess, she could escape at any time, but she was happy to play these little games. The daring rescues and bloodless battles gave her ponies such a sense of confidence and purpose!
But this one didn't go as planned. One small, stupid mistake got her thrown to the twisted reaches of the world-prison, Tartarus. Now alone, unarmed, and barely more than mortal, Celestia wakes in a living landscape where everything has every reason to hate her.
And, far worse, she has accidentally picked up a passenger.

Sidenote: This a repost (I tried to go through official channels, I promise!) of a story I wrote long, long ago on an account I foolishly deleted. Back in those days, Tartarus hadn't shown up in an actual episode yet. It's not exactly an alternate universe situation, but it has nothing to do with the canon portrayal of the place.

Super amazing cover art by Cold In Gardez.

Twilight is looking to hire guards for her castle. Derpy is looking for a new job. Lightning Dust is trying to find a way forward after her falling out with the Wonderbolts, and Flare Warden is just trying to get a position far far away from her brother.

Immense thanks to Fylifa for countless hours of editing and proofreading.

Starlight has decided to have a slumber party, since she now has a group of friends to do so. She and Sunburst decided to start off the festivities by summoning a Demon.
It turns out pretty good.

Based on what I thought was happening during the season 7 trailer, so it contains spoilers for that I guess,
Rated Teen for swearing.
This is now Part of the Cornerverse-MLP Universe. because why not?

Time may heal all wounds, but the scars and trauma left behind could change those affected in both expected and unexpected ways, and not always for the better. For some, time is enough, but for others, something more is needed. A distraction. Something to cling to when you feel there's nothing left. For the Princess of Equestria, that something was a mystery better left unsolved.

Fantastic cover art once again done by Mix-up!

Things have changed.

When Rainbow Dash unexpectedly arrives at the Badlands Hive, her open displays of hostility leave Princess Twilight Sparkle and Queen Chrysalis perplexed. The situation only devolves from there as differences in this Rainbow Dash are discovered, and it soon becomes apparent that two worlds have collided that were never meant to meet.

Twilight and Rainbow, each with scars both physical and mental, have to find common ground before time runs out. If they can’t, then the pegasus may become stranded in this world of changelings forever.

A crossover between the Little Flashes series and the Change series.

This story is a sequel to Revenant

Sunset Shimmer, for the first time since coming home, finally feels like she's home. She's got her own apartment, a new job, and, more importantly, a new group of friends that she couldn't be more grateful for having.

However, she has no time to celebrate, as the Armies of the Griffon Kingdom are knocking at Equestria's doorstep at the command of High King Sanguis Talon, and, with three of her greatest friends and two new ones, Sunset aims to keep them at bay.

Sanguis Talon, however, is not merely after conquest; he longs for something else...

It is highly recommended to read "Revenant" for the complete understanding of this work.

Rated T for profanity, sexual references, and scenes of violence.

Twilight Sparkle has been having nightmares for the past month. Every night, her dreams are filled with unspeakable horrors, and it all started when she'd received news that King Sombra had been captured and brought to the dungeons below Canterlot castle.

To conqueror your fears, you must face them first, and that is precisely what Twilight means to do.

Rated T for mature themes.

In a world full of magic, mere words can pose a deadly threat. When simply reading a sign can instantly infect the unwary, and cases start to turn up all around Ponyville, Twilight Sparkle casts the only spell she can find that can give her the time she needs to find the cause of the plague. But then she has to figure out how to stop the epidemic... without being able to read.

Princess Celestia’s School for Gifted Unicorns is famous across Equestria as a center of academic excellence. Only the best and brightest unicorns are offered places, selected by their academic merit, magical ability and passion for study. To make the admissions process as fair and reliable as possible, all candidates are given three exams by different teams of examiners, who then meet in private to decide which students are most deserving of a place.

Winner of the December 2014 Writeoff competition: Behind Closed Doors.

Following the return of the Crystal Empire, Twilight begins some intensive research into the history of the Empire and its late king. Modern historians know next to nothing about the enigmatic dark mage. Who was he? Did he have family? Loved ones?

The answers to those questions changes everything the Element of Magic knows about herself, and in doing so catches the attention of a shadow that yet clings to the frailty of life...
