A human finds himself in Equestria under very unpleasant circumstances with no explanation.
His reaction: get the heck out of Dodge and start a new life where Equestria and her ponies can't reach him.
But an alicorn's reach is long and the events which brought him here and his treatment in Canterlot are not so easily forgotten by those who did it. How does one say 'go away' to an immortal goddess?

Yay! Featured, thank you all.

Revised 08/31/14 for clarity and grammatical issues, no events changed. I am working on a sequel, but it will be from Fancy's POV.
P.S. Green is NOT Lyra. There are other green unicorns.

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

(XCOM/FiM Crossover)
(Sequel to Stardust, which I recommend reading before starting this. Fortitude Amicitia and Broken aren't required reading but are supplemental to the storyline)
(Gore tag for blood and violence)
(Alternate Universe tag because of the divergence from canon that Stardust has caused)
(Uses elements of Season 4)
(Coverart produced by the amazing Carnelian!)
(Many thanks to Arzoo, BradTheBrony, Vandenbz and Setokaiva for prereading!)
(As of 03/07/2016, the prereading team consists of Arzoo, BradTheBrony, Noble Cause and Metallusionsismagic!)
(Complete with it's own TVTropes page as part of the Stardust continuity. Could use some updating!)
(Character tags will be added as chapters are added!)
(Featured 5/12/2014! Thanks folks!)
(Possible spoilers in the comments! BEWARE!)

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."

Crossover with the Dresden Files. Sequel to Forever!

For his first task as the new Winter Knight, Harry must travel to the land of cute little cartoon ponies to stop a plot by the Order of Blackened Denarius that threatens both Earth and Equestria.

Warning: Includes massive spoilers for the Dresden Files series up through Ghost Story.

If she had been a good little filly, she would have listened to her mommy and daddy and her teacher and the esteemed mayor of Ponyville. If She had been a good little filly she would have stayed indoors, hiding under her bed as she waited for the Royal Guard and the Princesses to arrive and deal with the dragon. If she had been a good little filly, the kind of child that always got what she wanted for Hearth's Warming, she would not be on the trail leading up the mountain, to where the dragon now rested.

Glitter Belle is not a good little filly. She is a curious one, whose curiosity has brought her face to face with a very, very large dragon. Let's hope it's in the mood to talk.

Daring Do cannot believe her luck when she is asked to help explore the most ancient tomb known to ponykind. But terrible danger awaits her, for beneath the earth rests something beyond equine understanding.

Twilight Sparkle is one of the most powerful Unicorns in Equestrian history. But how would the events of the show change if Twilight, the Element of Magic, was never a Unicorn? Would she still be able to wield the element? Would she still make the same friends? Would she even be Celestia's student at all?

A small story. Don't expect a super long story out of this. Inconsistent updates is my specialty. Especially due to college. Have fun reading this cutesy story!

For so long, Chrysalis, Tirek, and Cozy Glow stood paralyzed in their stone cacoon; unable to move. To speak. To do anything. But that didn't mean they couldn't see or hear everything around them. For age after age.

The Russian version here.

This story is a sequel to We're Trapped in Stone, and We Must Scream

For so long, Chrysalis, Tirek, and Cozy Glow stood paralyzed in their stone cacoon; unable to move. To speak. To do anything. But that didn't mean they couldn't see or hear everything around them. For age after age.

But now they've been released from their confinement and are free to bask in a changed world. Unfortunately, the trauma of their ordeal doesn't just fade away.
