The Death Korps of Krieg, seeking atonement from their government's betrayal decades ago, they give their lives willingly in the everlasting fight against the enemies of the Imperium of Man. Averted by even their fellow Guard regiments, they show a high degree of fatalism and an unusual morbidity of habit. Yet they are highly disciplined, morally reliable and self-sufficient soldiers.

The 42nd Siege Regiment had been deployed on Kheltan III to reclaim a supply route that had been attacked by the Eldar. A simple enough task for the stoic men of Krieg. But an ion storm attack and an innocent experiment by an alicorn from another world can make even the easiest of tasks much more difficult.

A Warhammer 40K/MLP:FIM crossover

While organising the restricted section of the Canterlot Archives, Twilight stumbles across an old secret, one that Celestia had forgotten about, and Luna had hoped long buried.

Drawn back to the Boiling Isles for the first time in many years, the two find themselves wrapped up once more in old rivalries, conflicts, and the antics of a certain demented owl lady.

Neither Hexside nor Equestria have any idea what's about to hit them.

A blue box has fallen out of the sky, and crashed right into Twilight's Library! A strange brown stallion, calling himself the Doctor stumbles out. Soon after, strange stone Pegasus are everywhere, one of resident weather ponies has vanished, and Twilight is tossed in the middle! The Doctor and Twilight have to find out what's going on, before it's too late!

The Songbird, protector of the lamb of the flying city of Columbia was thought dead. Though as it would soon discover, his charge was not the only being able to open the mysterious tears. In the forest of this new land, he finds peace with the native animals. However, the urge to protect something, anything, would soon drive him to respond to the cheerful whistling of an equine with a penchant for protecting creatures like him, no matter how foreign they appeared.

No game spoilers, and the chapters that may contain vague spoilers are marked with a *
Contained within are the following characters from Bioshock Infinite: Songbird and the Luteces.

The immaterium is an unpredictable and fickle aspect of reality, and "impossible" ceases to be a valid term when it is involved.

As such, when Twilight witnesses a fantastical cosmic event occur above Equestria, she immediately investigates. What she finds is nothing short of one of the most dangerous artifacts to ever make its way to the relatively peaceful realm of ponies: a blackened suit of massive armor, marked by the ouroboros.

Warhammer 40,000 crossover inspired by Blooms in the Dust.
Now with a sequel, Forged Anew!

To the highly skilled operative code-named Naked Snake, today was not that good of a day. On top of being sent to kill his former mentor in order to prevent the Cold War from going nuclear, he had gotten captured, and lost his eye. While he did manage to escape, there was still much he had to do in order to complete his mission.
Still, even being tortured by someone with inexplicable lightning powers was somewhat preferable to finding himself outside of not only the mission area, but his world as he knew it...

Dark Souls/My Little Pony crossover

Whilst on her daily routines, princess Celestia of Equestria is startled by a flashing text informing her of being invaded by 'xXL0Lzah_69Xx'
You will probably know what will happen next.

Inspired by the legend who lives on.

I was half way through Dust to Dust chapter three when my IPad ran out of charge which made me lose a thousand words. So I thought Dark Souls would help… somehow.
I hope you enjoy this!

As Twilight re-shelves the books in the Books and Branches Library, her home for years, she comes comes across a strange notebook. A notebook with untold power, rivaling the powers of alicorn magic itself. The power within it could turn anypony into one of greed and power, corrupting the pony's mind with its power. In the wrong hooves it could rain chaos. If used in a just way, could aid thousands of ponies in need. But if used by Pinkie Pie, Celestia help us all. Twilight decides to keep it to herself, fearing what could happen if it fell into the wrong hooves.

But can she protect it from herself?

Shenanigans ensue.

A/N: I got this idea after buying Scribblenauts Unlimited today, and I couldn't resist doing it.

Will add tags as the story goes on.

This story is a sequel to Why No One Messes With Celestia

In the wake of Celestia's return to Equus, the ponies have worked tirelessly to prepare for the arrival of the Ascended. Defenses have been set up, weapons prepared, allies warned, but most important of all in the minds of both Diarchs, a cure for the Indoctrination has been pursued.

The Ascended, or the Reapers as they are known to the rest of the galaxy, are not amused. They attack in force, unwilling to stand by and let this small, barely space-worthy race of unascended quadrupeds neutralize their most effective weapon in their march towards galactic cleansing.

Now they too shall learn to fear the dark, and the Princess who controls it.

As the final battle dawns, the Emperor summons the full might of his forces in a last bid to destroy chaos. Seeing the importance in Equestria, he sends a portion of his space marine forces to defend it knowing that Abaddon will strike there. For if Equestria still stands where Terra falls, there may still be hope.
Takes place after "finding malcador"
