An MLP/Warhammer 40K Crossover

The Iron Warriors 38th Company has landed in Equestria, entrenching themselves like a barbed hook. They hunt the aliens of the Tau Empire, intent on destruction and pillage.
A small squad is dispatched on a reconnaissance mission, only to find that there is intelligent life on this world besides the feuding space-farers.
Will these improbably adorable and friendly equine aliens turn the damned warriors of Chaos from their blood-soaked path, cleansing them of their dark legacy with the magic of friendship and harmony?

No.
No, that isn't happening.
EXPLOSIONS!!

In the beginning, The Great Weaver brought together the world, from the mountains to the forests. Stitching it together, the Great Tapestry connects all living and nonliving things.

The Changelings found themselves especially connected to this Tapestry. Legend says that the first Changelings fell through the world as it was woven together, only to be caught on the First Weave beneath it all.

But what happens when something else is caught in the Weave?

Prince Phasmatodea, son of Queen Chrysalis, remembers what it was like before he hatched. He remembers being a human. He remembers dying. And he fully intends on avoiding another death.

But being gifted a new life does not matter when one failure, one false step, will lead to your untimely demise in the Changeling hive, for Prince Phasma must survive his toughest adversary from the start: Mother Dearest.

Tracy Maxwell is in a desperate situation: find somewhere to live, or lose the internship he needs to survive. After exhausting every property in the city, one last option appears the day before his deadline. Sure the agent selling the place is a little weird, and more than a little overeager to get the property signed off. At the worst, maybe there's a little mold in the bathroom somewhere, and he has to make do until the lease is up.

But then he steps inside and discovers things can be much worse. The property is in another universe, and while he's there he'll have to play by its rules. He's free to continue working his dream job, so long as he keeps to the contract. Even worse, he's got a roommate who has no intention of leaving him alone.

If he ever wants to escape, he'll have to read the Fine Print.

This story is a commission by _Kenzu_!

The problem with being an explorer in this day and age is that unexplored lands are few and far between. Almost everything's been charted, catalogued, analyzed, and what have you. But that's an almost; there are still those rare, blank spots in the maps, inexplicable, untouched by hooves, unsurveyed. One of those corners is Needle Vale in the far north. Supposedly cursed, yet everyone who's gone in has come back out. It has more stories about it than Celestia herself, yet every single adventuring group that's gone in has found nothing. Thanks to a nonstop snowstorm that's been blowing for centuries, no one's even been able to map it out.

Daring Do thinks there are too many stories about it to be a coincidence. Something is inside there. The source of the legends and of the snowstorm. And no one has a will quite as strong as Daring's (or so she tells herself). With a small team at her back, Daring makes a decision: she will go into Needle Vale, she will withstand the storm, and she will discover what’s going on in there.

But, as Daring is about to find out, there's a reason no one’s been able to pin down what's going on in that valley. Not everything that lies in the dark corners of the earth should be studied.

Loosely inspired by Annihilation. Has a dramatic reading done by Quinch.

A magical accident has a human end up in Equestria in the form of a unicorn.

Warning, Spoilers in comment section.

Sequel can be found here: http://www.fimfiction.net/story/306592/normal-life

Eighty years after the events of The Dread Chitin, Equestria is a radically different place. The arcane science of the late Duran Thirk and the information found on the Star League library core have combined to catapult the nation's science ahead by hundreds of years.

Now, facing the possible aggression of a completely unknown alien power, Twilight Sparkle and her friends have to gather together once more, leading a crew of the best ponies they could assemble in a voyage outside their own star system. They seek to learn about their potential foe, to explore the galaxy around them, and possibly find allies and friends to stand alongside them. Who knows what they will actually find?

This story is a sequel to Tactics of Snowbound Unicorns

Harmonic bonds aren't the most predictable of spells. Sunset learned this the hard way with Twilight. Involving Moon Dancer will make things either extremely complicated, or extremely simple.

And that has nothing to do with harmonic bonds.
