When Twilight first began her experiments in trying to figure out better ways to access the Aether, the realm of magic and souls just outside their physical realm, she did not expect to make significant progress. After all, pony kind has been trying to find out the answer to that line of thinking for centuries.

When she felt herself connect to the other realm Twilight accidentally manipulated its energies in a different sort of way. The Aether bent to her will much easier than before. Getting just a bit too excited, Twilight played with the Aether a tad too freely and the reality-bending powers of the outer realm sucked her into its bottomless depths.

Fortunately Twilight was able to direct herself back to the material realm using the closest, and brightest, soul she could find as an anchor. And the second she looked up at the skull of the skeleton sitting on top of a golden throne, she knew life was about to get more... interesting.

(A crossover with "If the Emperor had a Text-to-Speech Device")

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!

This story is a sequel to Forged Anew

Twilight has earned the trust and loyalty of both Hesperos, a former Rubricae of the Thousand Sons, and Te'kan of the Salamanders. In the idyllic realm of Equestria, the need for such mighty warriors is nonexistant. However, outside Equestria's borders are lands wild and dangerous. Worse, the galaxy the astartes call home has not forgotten them. Together they face the final fate planned for them deep within the maelstrom of the warp.

A Warhammer 40,000 crossover.

This story is a sequel to From Dust

Twilight Sparkle is many things, but above all else, she is a friend. Her most recent acquaintance is, however, a most unusual sort.

Never before has Equestria played host to a traitor space marine of the Adeptus Astartes.

As an armor-bound soul with a body burned to naught but ash and dust, how will this former being of war fit into the love and harmony of the pony domains?

Surprisingly well, all things considered.

A Warhammer 40,000 crossover.

Driven by an intense Warp storm, a Rogue Trader vessel finds itself crippled and stranded above a world no human has ever visited. The natives are friendly; can the visitors say the same? A Warhammer 40k/Friendship is Magic crossover. Yes, really

~STORY COMING SOON~

Disclaimer: the Stars of Twilight are a custom Legion/Chapter of my own creation.

Twilight Sparkle never expected that she'd become an Alicorn Princess, but decided to make the most of it. She faced many hardships and struggles against the Nobles that opposed all the changes she tried to bring. Her friends, family and fellow princesses always gave her their support, but it wasn't enough. No, of all people, Twilight got her reassurance from a godly being that she met and befriended in a pocket dimension she accidentally found one day. Worried for His new companion, the being decides to make contact with one of the Lost Legions. He may not have appreciated it then, but now He was thankful that the worlds ruled by His XIth Son were unknowingly worshipping the youngest Alicorn as their Goddess.

Main theme of the story is a loose adaptation of the Assassinverse stories made by The Sinestro Joker, except that in mine Twilight doesn't die in the first act.

An undead Emperor in need of a new body. A Spartan lost in space. A ragtag team on a suicide mission. What do they all have in common? They all wind up on the magical world of Equestria, where war has been forgotten. That, however, is soon about to change.
When each of them is about to be retrieved, ancient evils arise to unleash hell upon the unsuspecting world. When the forces of three galaxies clash around them, can our favorite ponies hold out against the onslaught?
This is a crossover involving Warhammer 40k, Halo, Mass Effect and MLP, and is also my first fanfic. Comments and reviews are welcome.
Rated T for language, violence, and general adult situations.
Now on Tv Tropes!

Heartbroken from her friends and brother abandoning her at the wedding rehearsal, Twilight Sparkle retreats to a strange new world and is later followed by Spike and Rainbow Dash. Once there they encounter new races, strange technology, gain great power and see to the foundation of a new empire. But while there they experience constant warfare from many enemy factions that seek their destruction, turning the innocent ponies and dragon into naught but a memory. So now there is only one question: when they return to Equestria, will they come as peaceful diplomats, or conquerors?

Universe in set in a Halo/Warhmmer 40k/Star Wars mixed galaxy.

Not sure if the action sequences will actually be gorey, but the tag's there just in case.

(This is a Displaced Story. If you hate them, please leave)
People don't know how agonizing it is being alone for a few thousand years, stuck in a chair the whole time. Let me tell you, it's not fun. Then, this teeny weeny 'Princess' shows up and acts like she's the boss. Oh, and Sparklebutt is there too.

So, how did this happen? It's was probably that angsty Merchant asshole. Should never have bought from him. News flash kids: when a creepy Merchant guy walks up to you with very desirable wares, walk the fuck away. It's a damn trap.

But the worst part of my endless torment? I'm a fucking corpse sitting on a golden throne, writhing in agony as I slowly decay into nothingness.

....fuck you, Merchant Asshole.

And Sparklebutt, JUST. FUCKING. STOP.

(If The Emperor Had a Text-to-Speech Device)

When Twilight was born, her parents weren't who she thought they were. Regardless, the two god-like entities loved her dearly, not wishing to depart with their beautiful daughter... However, after an incident involving an malevolent entity, that wanted her for some dark plot against all mortal beings, they agreed to disguise and send her away. The decision becoming more painful to both sides, as the link keeping the two god-like beings together, had been cut.

Twenty years later, during an attempted spell, Twilight had been attacked by the entity once more, taking its new chance at her. With its link to her world cut, only able to manipulate the spell, the Entity decides to send her to a different realm, where he has his pawns lying in wait to capture the valued prize. Now, the princess finds herself fighting along side the web-slinging hero, Spider-Man. Though, they have another ally that had been sent to protect Twilight at all cost, even if death comes for him. This protector being something neither teens had ever seen before in their life time...

An Astartes of the XV Legion, one of the Thousand Sons.
