Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

A normal day was all it took.
A simple failed prototype, a missed experiment.
There was an explosion, and I woke up. I don't really know what happened between those two events, but I'm fairly certain I shouldn't have awoken in a small, dark box.

I'm scared.

In a desperate attempt to alter the course of history and save Equestria from extinction, the Alicorns send Twilight Sparkle far back in time to a magical world that once existed, where she, with the help of Megan Williams, must prevent the wake of an unstoppable enemy. G1/FiM crossover, based on the X-Men movie and comics storyline 'Days of Future Past'.

A thousand years after Twilight became a princess, Celestia requests a final friendship report from her.
With all of her friends gone, the lessons they taught Twilight will be echoed in one final letter.

Takes place after season 5, but before season 6.

One year after the reformation of her star pupil, Starlight Glimmer, Twilight Sparkle decides to look more into the forbidden mysteries known as Alternate Timelines. After tweaking around with Starswirl the Bearded's altered time spell, she tests it out in an open meadow.

But she honestly didn't expect it to work.

She honestly didn't expect to pull not one, but two blood-covered children from beyond the veil.

And she honestly didn't expect to find herself fighting for her life against a desperate monster.

I do not own the cover art. All rights go to the original artist.

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.

Carrie "Carrietta" White is a normal, shy unicorn who is constantly picked on and misunderstood by most of the students at the School of Gifted Unicorns. What's worse is that her mother is a religious fanatic who abuses Carrie after her father abandoned her. After hearing about the latest incident at the School, Princess Celestia turns Carrie over to Princess Twilight Sparkle to help her overcome her fears and her humiliation. What no pony knows, other than Twilight, is that Carrie possesses a secretly powerful magic that may bring utter chaos and destruction if not controlled properly due to her emotions.

Can Princess Twilight successfully give Carrie the self-confidence she needs to overcome her fears from her classmates and to control her newly founded powers or will Carrie succumb to the vengeful madness and fury that is secretly building up from within her very soul?

This story is a sequel to Celestia's Tiny Student

(Title changed from "Ponyville's Tiny Librarian" for reason pointed in this blog )

Twilight Sparkle is a one-kilogram pony the size of a large rat, shrunken by Princess Celestia following her entrance exam to the Celestia’s School for Gifted Unicorns to ensure that her power surges would not pose a danger to the ponies around her.

She’s spent thirteen years full of hard training at her new size, facing the life-threatening experiences that came with living in a world of giants. To survive those thirteen years of hardship and joy, of learning and adventure, and of pride and humility, Twilight has challenged herself to be stronger, to overcome any obstacle.

Now that tiny Twilight is on her way to Ponyville to oversee the preparations for the Summer Sun Celebration, how well will this miniature mare fare outside of the confines of the castle? How will the other Element Bearers react to her? How will Nightmare Moon react to the tiny unicorn? Is Twiny prepared to face Ponyville, and, more importantly, is Ponyville prepared to face her?

To celebrate the release of this sequel, I created a group called “Twinyverse” for all fans of this story where you can talk about it and track all side stories with ease.

During the entrance exam to Celestia's School for Gifted Unicorns, Twilight completely loses control of her magic. Celestia tries in vain to calm her down, but having no other choice she's forced to use a shrinking spell on the filly in order to tone down her dangerous surge of power.

After the exam, Celestia takes the tiny Twilight as her personal student to teach the young unicorn control over her powerful magic, making sure that she will pose no threat to other beings.

Will tiny Twilight be able to step out into a world designed for someone far larger than her? And will her size impede her in the trials of life as princess personal student ?

This story is a sequel to Stardust

Twilight has finally returned home from the harrowing challenge that Discord set upon her, and the residents of Ponyville and the Elements especially look forward to having their dear friend returned to them.

Twilight, however, has changed. Still suffering from her injuries, almost incapable of using magic and haunted by the memories of her time on Earth, she becomes increasingly withdrawn from those who were closest to her. Will her frustration at her current state and her friends inability to understand her experiences cost her what she valued most before Discord's bet?

(Sequel to Stardust, familiarity with this is recommended!)
(Proofread by Arzoo!)
(Coverart commission drawn by the amazing KairaAnix!)
(Crossover with XCOM: Enemy Within, though the crossover and human elements are minimal)
