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!!

Ponies like snuggles. Spike likes to give snuggles. But Spike is a five-hundred-foot tall dragon, and finds it difficult to give snuggles without accidentally popping the pony like an overripe tomato in a hydraulic press. Spike believes he has found a solution.

Part of the Hellpiercer 'verse, but knowledge of that story is not required.

Princess Twilight Sparkle has sought long and hard for the weapon of which the old tales tell. Hellpiercer, mystical lance and bane of the Wraithworm, has at last fallen into her possession.

She sets out to take it to the great dragon of the Badlands, praying she arrives in time.

An utterly fluffy story.

Part of same 'verse as How to Hug a Five-Hundred-Foot Tall Dragon.

Discord has a problem. He has a tendency to not think through his actions all that well, poor impulse control, and no ability to figure out how others will feel about what he does. Even with a friend helping him, sooner or later he's going to do something that'll get him stoned or hit with a reforming spell or whatnot. So what's he to do? Ask the smartest pony in Equestria for a solution, of course!

He probably wasn't expecting to get "Have Celestia let you rule Equestria again" for a response.

No one else was probably expecting to enjoy it.

Now with a reading by Crafty Arts!
And a Spanish translation!

Once upon a time there was a very lazy dragon who did not want to find a town to pillage.

So he decided to make one of his own.

This story is a sequel to Unchanging Love

The explosion of love from the defeat at Canterlot hit harder and reached farther than any changeling expected. Firefly felt the effects as much as any, but she also gained something wonderful and priceless from it. Though this gift brought her a kind of joy she had never expected, she fears one question more than anything.

What trials will she and Fine Roast face when the invasion's inevitable fallout reaches them?

Big thanks to Cursori, SigmasonicX, Dogman15 (Chapters 2-5), and Ghost Mike for editing.

Friendly heads up. Beware the comments, they may contain spoilers!

It’s the week before the Canterlot wedding and tensions are high, even more so for the changeling love collectors. With the results of the wedding, life is going to change drastically, regardless of the outcome.

For one co-owner of the Sweet Roast Cafe, wife to a loving stallion, and undercover changeling, Sweet Leaf can only hope this change is kind.

This story is a sequel to That Changeling's a Pony!

Like most ponies, Maxilla the exiled changeling doesn’t believe that Daring Do is real. However, fate seems determined to prove her wrong in the most dramatic way possible.

After all, it isn’t every day that a changeling gets dragged along on an adventure and subsequently immortalised in Daring Do literature and merchandise.

Dragons. Big. Selfish. Treasure mongers. No other creature in Equestria is as selfish as they. The spend their entire centuries long lives building and hoarding huge stockpiles of treasures, which they guard fiercely and frighteningly. Many are the treasure hunters who've attempted to cash in on the goldmine that is a dragons hoard. They almost always regret it.

One dragon is actually really strange about it, however. Oh, he has a hoard, which he guards just as fiercely as any other. But! But, he actually has the capacity to trust certain ponies and other creatures enough to let them gaze upon his most precious of treasures. This isn't the most surprising thing, however, despite its seeming impossibility. No. The most surprising thing is just what treasures his hoard contains...

You'd think that being trapped in stone would mean that, if nothing else, I could get some peace and quiet. Unfortunately, it seems that Celestia has other ideas.

She has appointed these ponies... these 'Keepers', as she calls them, to keep me entertained during my incarceration.

Honestly? I'd prefer the boredom.
