Twilight Sparkle has too much magic, and it will take her decades to learn to control it. Her spectacular loss of control during her entrance exam only proves that fact. She is a danger to herself and others.

After Sunset Shimmer’s disappearance, Princess Celestia needs a new student to bear The Element of Magic to defeat Nightmare Moon. With all of Equestria at stake, Twilight Sparkle…is not the pony she needs.

Princess Celestia seals Twilight Sparkle’s magic with the distant promise of one day teaching her.

But there are two diarchs of Equestria. Amidst a lucid dream, an offer is made.

“Hello, Twilight. Would you like to be my student?”

The Badass Twilight tag applies more than ever, but please note the new tags.

This story is a fairly direct continuation of The Celestia Code. You might be able to follow it without having read The Celestia Code first, but it's better if you do.

The sequel is here: The Twilight Enigma

Most excellent pre-reading/editing done by the erudite AcademicPony and the dapper statoose!

Do you see a dark tag? No, you don't. Not dark. Well, okay, there are a couple of dark-ish bits, but that's all. Not enough to warrant a tag. Speaking of tags, there really ought to be "Badass Twilight" and "Friendshipping" ones.

Sequels and side-stories (and more) can be found here Offprint and AO3, and a hardbound two-volume set of all that can be ordered from The Ministry of Image.

My editor for the first edition of this story was Gogito, and I can't thank him enough for all the hard work he did. My editor for the revised version was PresentPerfect, and he did a terrific job of getting the story into excellent shape.

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

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!)

(Crossover with XCOM: Enemy Within, though the crossover and human elements are minimal)
(Featured 4/28/2014, thanks folks!)

Celestia and Luna were born as unassuming foals in troubled times. But already marked for greatness, the simple earth ponies stand to face a world set against them, full of danger, fear, and sadness. A world they will change forever.

A sweeping epic taking place before Equestria was made, where Celestia and Luna must rise from normal foals to become the Princesses we know them as, beset from all sides by monsters, other ponies, and even the forces that govern nature. Their tale is as tragic as it is triumphant.

Currently on hiatus. For more info, go here.

Equestria is dying.

There is nothing anyone can do about this.

The sun has shined too long. The Age of Sunlight must come to an end. But Celestia refuses to let it extinguish, and the land is shrouded in everlasting dusk. And now, among the living, are seen bearers of the accursed Darksign. Those doomed to die, again and again, until their minds fade away and they turn hollow, forever seeking the souls of others for nourishment, in a futile attempt to regain their lost memories and lives. But there is now only one way for their suffering to end. Celestia must be slain, so that the Age of Dark may take its natural turn.

'Dark Souls' crossover.

It has been three months since Rainbow Dash passed away into Elysium, joining Pinkie, Fluttershy, Applejack, and Rarity. Meanwhile, Twilight's body has been frozen in time, unable to join her former friends. As she considers the meaning of loss, strange nightmares come over her, forcing her to turn to Luna for help. As they spend more time together, though, just one question arises- will either ever find any happiness that doesn't need to end?

Back from the dead by 09242014! On 09082014, updated description and tags. Removed "OC" and "Alternate Universe", added "Dark" and changed rating to "Teen", just to be safe. On 09222014, deleted the first seven or eight chapters. That's why the view count is so low, but comments and responses are much much higher.

Robert Anderson is your average Jo. By day he works for a respectable Video Game Company as an animator, is into Steampunk and owns a small apartment where he lives alone. By night however, he is Violet Runner a fan of My Little Pony; Friendship Is Magic (despite the fact that the show has been canceled for the past 4 years and most Brony activity has gone underground) and finishes and sells scraped pony games (such as Fighting Is Magic) as well as Animated Fanfics.

Since the shows cancellation a lot of Bronies have become out laws do to the government thinking the New Lunar Republic and Solar Empire are dangerous gangs and that some Bronies have even broken into Hasbro's headquarters around the world in order to try and find unaired episodes.

It was after one of those raids that a Brony by the name Crescent Sliver disappeared after releasing information that alluded to something called The Maretrix. And it is this question that keeps Violet up at night, searching for an answer.
