First of the Savage Skies series.
After running afoul of timberwolves in the Everfree Forest, Fluttershy is saved by a mysterious young colt with a most unusual and disturbing feature. Realizing that he is alone, without anyone else to care for him, Fluttershy realizes that she must try to bring this lonely foal out of the forest and give him a life of love and friendship. The problem is that this colt's...unique qualities have made him more than a few enemies, including some who are closer to home than Fluttershy realizes.

Now with a sequel: The Promise of a New Day.
Now with a TV Tropes page.

The "what-if" sequel has arrived -- Equinophobia: Silvery Lies.

"Equinophobia is a psychological fear of horses"
Sometimes you're lucky, and sometimes you're unlucky. Ryan finds herself the latter as she ends up in a world of sunshine, rainbows, and pure horror.

A story of an out-of-place person learning to adapt to their new environment.

Alternate Universe tag for lack of or changes in Equestria Girls elements and the Crystal Empire's history.

Written as the A-side to A Chromatic Scale. The stories are not related otherwise and can be read separately.

Last night, Dusk Shine-favorite student of Prince Helios and newly ascended alicorn-went to bed in a Ponyville where all of his friends were stallions and a major event was about to happen the next day. When he woke up, Dusk Shine had swapped placed with an alicorn mare named Twilight Sparkle. And, all of the friends and ponies that were male in his Ponyville were now female.

But, with the Princes (or is that Princesses?) coming tomorrow, Dusk Shine has no time to figure out what happened or what went wrong. Preparations need to be made and friends need to be consulted to get ready for the event. After all, everything else was just like his Ponyville. Surely it shouldn't be a problem, right?

Right?

A story that is inspired by and runs parallel with One Of Those Days by Taranth.

This story is a sequel to The Witching Hour

Midnight Storm has had one heck of a year. She's gone from being a wandering outcast to a respected and liked member of the community of Ponyville, a captain of a secret guard created by Celestia herself, and even a mother.

That was last year.
This year she'll have to deal with chaos entities, rogue dragons, and her past. And that's all just before Nightmare Night!

Follow Midnight and her friends and family as they chart their way through one life changing event after another in part 2 of The Witching Hour!

This is the story of a brony, who inserted into Equestria.
But instead of a pony, he became the enemy of Celestia.

Would he decide to do what’s right, to love and tolerate
Or would his evil changeling nature make it hard to integrate

Then there is the question of the duty that is his natural birthright
Tasked by the changeling Queen, he was to murder Princess Twilight

So, here’s my attempt at a SI with a bit of a twist that others have done before. Go to Equestria, end up on the wrong side of the tracks, and have to deal with it. Enjoy!

Three years ago, Gilda volunteered for a posting in the farthest reaches of griffon territory, a place she knew no pony had ever been and a place she hoped no pony would ever come. And then one morning...

The first chapter was written for the 2014 Summer Equestria Daily Pre-Reader "Secret Santa" Story Exchange--better known, I guess, as the EqD Pre-Reader Battle, but the story just kept on growing. The prompt was the single word "foreigner," and the cover image was commissioned from DarkerSounds.

His evil was legend. He was an entity of incalculable power and unparalled malice - his icy soul utterly consumed by his plans to destroy all of life, until he was stopped and defeated. But what if that wasn't the end? What if he was given a second chance, in another world? For he was not always like this. Nobody is born evil. But anyone can turn evil. Will he become a hero? Or is he doomed to repeat his mistakes and walk the same path as before, the Path of the Damned?

AUTHOR'S NOTES:
1. This is my first fanfiction, so honest criticism is appreciated.
2. This is a crossover with Warcraft universe.
3. English is my second language, so you will have to forgive me for possible grammar mistakes.
4. Hope you like it.
5. There is a prequel called: Project Eclipse.

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."
