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!!

Nopony ever said the friendship between Fluttershy and Discord would be an easy one. The difference in their life expectancies doesn’t help, but that’s a problem Discord can fix with a snap of the talons—that is, until Fluttershy finds out. Discord isn’t one to give up easily, though. He’ll do anything to keep his one and only friend. Anything.

There is now a video review! And still another video review! And Russian and French translations! And there are dramatic readings from Joehighlord and Dr. Wolf! But wait! There's more: Dr. Wolf has collaborated with Meb90 and a team of other talented artists to produce something amazing.

The name's Applejack. Canterlot, the capital of our kingdom was beset by a plague of changelings durin' a weddin'. Had it not been for Cadence and Shining sendin' them packin', we might all be changelings by now. Not long after, Princess Celestia ordered a stallion from every house to enlist for the counterattack against them. He served his kingdom, as did countless other colts, and he came back without a scratch on him. Or, so Ah thought...

Every pony in Equestria knows the names Octavia Philharmonica and Vinyl Scratch. Every musician in Equestria knows and reveres their talent and most semi-jokingly complain that Octavia and Vinyl's relationship should count as a monopoly on musical talent. Very few know their early story, years ago when Octavia had only just left Canterlot Conservatory and Vinyl was... well, being Vinyl.

This story is a sequel to A Song of Storms: Of Skies Long Forgotten

It has been twenty years since the fall of the Cirran Empire, and Commander Hurricane has led the pegasus pony tribe into a comfortable role in accordance with the Tri-Pony Compact. But a supernatural blizzard without end brings forth the suppressed hatreds that have festered among the three tribes, and the resulting famine threatens to eradicate all; earth pony, unicorn, and pegasus alike. With a bloody war looming on the horizon and the fate of their ponies at stake, the three tribes must find a way to survive together, or they will assuredly die alone.

Sequel to "Of Skies Long Forgotten." Reading of that story is not absolutely necessary to understand what is going on, but it is strongly recommended for you to understand the references.

How far will you go to save your family? Your friends? Your empire? Twenty years before the events of the Hearth's Warming Eve story, long before the pegasi had even met the other two races, Commander Hurricane was a simple farmer in the great Cirran Empire. When the neighboring griffon nation declares war on Cirra and everything it stands for, the young Hurricane finds himself thrown into the middle of a conflict with the fate of his very race put into question. Will he rise to be the pegasus Cirra needs him to be, or will the mighty empire fall to the claws of the griffons?

The Shaper is a smith of unparalleled skill, her creations the most sought after in the fallen world. When a pony named Lyra comes to her with a unique commission she has to put all her skill to the test to craft a weapon of great power. For Lyra's goal is not an easy one, and it is not just any weapon that can kill a Dragon.

A story inspired by this and this image, as well as this challenge by CDRW (whose fic A Still More Glorious Dawn Awaits is quite good).

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

[Part One of the Riflepony Series] When an unexpected heat wave scorches Appleloosa, Braeburn finds himself unable to save his family's apple orchard. That is, until he meets a certain pony whom he thought to be fictitious. The mare tells him of a treasure that is said to be buried in the town of Dodge Junction, and asks for his assistance in finding it. Will the tales of Cunning the Colt's treasure prove to be true, or were they simply folktale?

"My name is Lyra Heartstrings, and you will not remember me. You won't even remember this conversation. Just like with everypony else I've ever met, everything I do or say will be forgotten. Every letter I've written will appear blank; every piece of evidence I've left behind will end up missing. I'm stuck here in Ponyville because of the same curse that has made me so forgettable. Still, that doesn't stop me from doing the one thing that I love: making music. If my melodies find their way into your heart, then there is still hope for me. If I can't prove that I exist, I can at least prove that my love for each and every one of you exists. Please, listen to my story, my symphony, for it is me."
