(This is a Crossover with Halo. If that genre offends you, you need not read any further.)

Cortana has several problems, and very little she can do to solve any of them. Being stranded on half of a ship in deep space, with the clock on her lifespan slowly running out, she gets desperate enough to try almost anything.

She goes so far as to land her half-ship on a strange astronomical anomaly, in the slim hope of finding a method of FTL travel on it. Now, her latest problem consists of understanding the mind-bending physics of this planetary crime against reason, without prematurely going insane.

Chief wakes up on a new planet, and is, as always, presented with aliens he needs to kill in order to accomplish his mission.

Equestria witnesses the arrival of a large object from space, and has to deal with the fallout of it's destructive crash landing. Though the real threat the object poses is not something anypony could have anticipated.

(Knowledge of the Halo games is advised, though not strictly required.)

I am currently looking for an editor, pre-reader, and/or proofreader, preferably someone who can double check me on the lore when it comes up. Shoot me a PM if interested. I've got a few people who have generously offered their help. Thanks for offering to help make this as good as it can be!
Will update tags as story progresses.
Fair-warning, this story is secondary to my other one and will update less frequently.

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

Darth Vader is one of the most despicable forces in the galaxy. Once a powerful and respected Jedi Knight, he betrayed the Galactic Republic and Jedi Order for the dark side of the Force. The newly christened Sith Lord was apprenticed to Darth Sidious and quickly became a master of the dark side. Vader was soon the scourge of the Jedi, continuing the Great Jedi Purge by slaughtering all remaining Jedi.

An extension of Emperor Palpatine's will, the Dark Lord was constantly on the move, traveling throughout the galaxy to defeat rebel uprisings and kill any surviving Jedi. This mission brings him to the edge of the Outer Rim into the Unknown Region of the galaxy, in an unknown star system. High above an unnamed planet he duels with one of the last remaining Jedi in the galaxy in a starship battle. But during the battle his ship is damaged, and he crash-lands on the mysterious planet.

With his connections to the Galactic Empire severed, Vader must find a way out the land known as Equestria, inhabited by the strange creatures known as ponies. That, or he could take it over.

Often called a psychotic, meth dealing hillbilly with a habit of untamed violence and murder sprees, Trevor Philips is someone that no one wants to mess with. The body pile he leaves behind and then sets on fire just for the heck of it proves that. But after a particularly deadly drug deal gone wrong, Trevor finds himself in a place even his disturbed mind has difficulty comprehending.

The feeling is mutual for the ponies.

The thick growth of the Everfree Forest harbors many secrets. Some, it shares with the adventurous souls that seek them out. Others are well-guarded for a reason.

Lyra Heartstrings, a graduate student in Canterlot University's archaeology program, is no stranger to discovering lost civilizations. When she finds a survivor from one, however, she begins helping him to restore his culture.

The question burning in the back of her mind is, "At what cost?"

This story was written as a commission for genuis101. We both know that the "Lyra and Humans" thing has been done to death, but I wouldn't have taken this project on if I couldn't breathe some fresh life into the trope.

Cover art is by Gaiascope. Follow him on Tumblr if you like his artistic style; you won't be disappointed.

Special thanks goes to my shrinking pool of pre-readers.

Frank Horrigan is the Enclave's finest instrument of warfare and the best soldier they've ever had. Known to all as a "genetically engineered cyborg psycho total homicidal maniac", and a kind of "ultra super mutant in power armor". Having been witnessed laughing off plasma rifle fire, and punching deathclaws and armored humans in half, he is one of the deadliest entities to have walked the Wasteland.

Killed by the Chosen One, the Enclave Oil Rig sinks to the bottom of the ocean in a nuclear explosion. But this isn't the end of Frank's adventures. Out of all the odds, he ends up in Equestria of all places. One of the most despicable monsters of the Wasteland in a magical land full of friendship and sunshines. Yeah, this will end well.

At the end of each chapter, Frank will make a Karma Decision. You vote for either the Good, Neutral or Bad decision in the comments for what he does the next chapter. Vote wisely!

Thanks to my super awesome proof readers ArmedBrony, Eldorado and Shadowflash, all kickass dudes that can comprehend my writing! A rare skill indeed.

An Eve Online/MLP crossover

Keyan Charante, a fairly successful explorer, finds himself trapped in an unknown system after going through a wormhole. After discovering the only other sentient species in the galaxy, and some bad luck, he initiates first contact. The following adventures span the stars and Keyan soon learns that there are more important things in the galaxy than isk.

Set sometime before the season 2 finale.
Isk is the currency in EVE online.

I am going to try to make this so you don't have to know eve lore for it to make sense but every little bit helps.

Feedback and criticism is welcome in the comments. I hope I make this worthy of your time to read.
