After a spell misfires, Twilight and Big Macintosh find themselves trapped in a world like none they've ever seen before. Together, they will face adventure, hardship, loss and longing, as their shared experience brings them closer together.

When Apollo 11 lands on the moon, Neil Armstrong utters his famous lines as his boots land in the lunar regolith, but when he turns around he finds something no one was expecting or had ever planned for.
There's an alien on the moon. And it's blue, four-legged, and staring at him.

Sequel here.

(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.

Humanity has fallen.

After only a year of plague, savagery, and drought, the temple of humankind could sustain itself no longer and the world was plunged into the darkness of extinction.

But it was not the end, not truly. Far below the dirt and abandonment, humanity lingered. It was here, within sprawling concrete and steel, that the last remnants of mankind remained, locked away from a changing world.

It is here that two men awoke. It was here that a revolution began. And it is here that the fate of humanity will be decided. Because, here, there is no turning back. Here, there is only one direction to tread:

Forward.

They taught me how to put that uniform on... I just can't get it off...

Nopony knows where this human came from, or why it is here. But to Princess Cadance and the Elements of Harmony, it is a quite a surprise to her to see this silent creature that was once to be thought just a myth.

But, to US Navy SEAL "Lucky", the now lone survivor struggles to endure the loss of his brothers, as well as figuring out what to do in this strange world that has once never lived in war for generations.

(Nov. 16, 2013) WOW!! Holy hell, in just a day my story has already hit the popular story section! All I want to say is thank you so much for liking this story! I really appreciate all the positive feedback, and I respect those who say they'll be joining the military soon! Thank you!

I was just on my way through the forest when I saw her crash. I couldn't leave her there...what's a small detour on my usual trip. Never had a traveling companion out here before anyways.

The common household Sweetie Belle has many uses and applications. Here are a few of them.

This story is a sequel to Doomguy Wants It

Nightmare Night finally arrived and Luna was having a wonderful time with Twilight. And everything was going well for the small town of Ponyville, 'till Rainbow Dash decided to prank the blood thirsty space marine that went berserk over Smarty Pants just a month back. Now please list all the things that can go wrong with that idea.

I'd like to say: All the ponies who are hurt or harmed in anyway in this story are not ponies I hate. This is not some type of trollfic or story I'm writing just so I can write about hurting one of them. I love all ponies deeply and equally *Cough*Except for Luna*Cough* and that *Cough*She's best pony*Cough* all of them get hurt equally.

Now please don't take this story seriously and have a Happy Halloween!

In search for a replacement for his pet Daisy (his rabbit). Doomguy finds himself in Equestria right after Twilight enchanted Smarty Pants with the Want it Need it spell. Now what could possibly go wrong with a Blood Thirsty marine who just defeated the minions of Hell more than once?

You may experience some naughty words!

don't worry the ponies don't swear.

A Man. He hungers for vengeance from a time when the world including Equestria was still primal. It was before Celestia and Luna graced it with utopian peace and harmony. What if every thing about their rule is built on the bones of other civilizations? What if those old pony tails aren't just stories but the few bits and pieces that remained of the truth? The fables of monsters and intelligent races not like ponies are more then fiction...they are dying embers of a time before.
