A colossal mass of alien matter ends up on the surface of Equestria as a result of a cosmic disaster, and it is poisoning all it touches. Twilight Sparkle and her friends are caught up in the events as Equestria becomes increasingly hostile to ponies, and the ponies become increasingly hostile to each other. But is it the fault of the alien matter, or is something more going wrong?

It is up to Twilight to find the answer and a solution, preferrably one that also preserves the very fragile life of what may be the last representant of an entire species.

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.

Dearest Shining Armor,

By the time you read this, I’ll be long gone.

Originally a one-shot written during a very trying time, but many people asked for a continuation. You can read the first chapter by itself if you wish, and that may even be advisable, but I still hope that you'll enjoy the rest.

One Doctor has just had himself removed from his universe in order to save it. The other is traveling alone after a disagreement with his wall-eyed companion. They are in for just a bit of a surprise when their TARDISes collide in transit.

The Producers have long been the bane of the Top Gear team's existence, sending them off into the most dangerous and hilarious of situations in the name of good television. Now follow Captain Slow, Hamster and Jezza as they are sent off again into the unknown as some of the first humans to set foot (Or wheel) into the land of Equestria.

Oh, and the Government isn't exactly on board with this one either...

In her youth, Twilight Sparkle discovered a way to infuse technology and magic. 20 years after her breakthrough, she is now the CEO and founder of Sparkle Industries, and one of the wealthiest ponies in Equestria. Her relatively perfect life goes sour, however, when she is captured by a group of griffons who want to steal her technology.

"Is anypony out there? Please, my name is Trixie! I need help! I think... I saw a cockatrice. I can't move, I can't see. Please, somepony, anypony.... Help me."

Laid low by circumstances beyond control, trapped in a cruel and unrelenting prison of flesh made stone, can anypony hold out hope to see the day once more? When their life rests in the hooves of one whom they tried to humiliate and belittle, can they trust in them and make it right? When they can only see through the eyes of another pony, when only one other can hear them, can they stay sane? When the only chance for their freedom is a fool's hope made incarnate, the impossible made improbable, can they beat the odds? Trixie is going to find out.

Pride can lay one low. Stubbornness can leave somepony friendless. Anger and Sorrow can turn others away. And yet, they can give strength. And Hope, in the darkest hours.

If you're afraid of Dark tones, or find them distasteful, or can get stabbed easily in the feels, I suggest reading on only with caution. This is not a happy tale.

Princess Celestia is an ageless, immortal being. Almost entirely unique except for her sister Luna, and she was gone for a thousand years. One would assume that no other pony in the entire world could possibly be able to truly relate. One would be wrong. There is one other. He's no all-powerful alicorn. His greatest power is his intelligence. He comes and goes at will, but always seems to be there during her worst moment. Sometimes he has a different face. Once he was a unicorn. And at times, it seems she meets him out of order. But he's a fantastic friend. Simply fantastic.

*Note: Even more than "A Friend of the Night" this story is going to be more along the lines of a series of interconnected short stories. Some chapters might end up being a bit short as a result.*

When two events collide through the fabric of space and time, Coop, a hotshot gamer whose skills with a controller are only match by his hunger, along with his giant robot car named Megas, wind up in a land of colorful talking ponies.

To make matters worse, he's been turned into one of them.
He'll have to learn how to handle the wheel with hooves quickly. Because even in Equestria there's plenty of trouble he can get into. Will this snack munching, video gaming, giant robot piloting force of destruction be able to cope?

With Twilight Sparkle, Applejack, Rainbow Dash, Rarity, Pinkie Pie and Fluttershy charged with watching over him, let's hope Celestia made the right choice.

Who knows? Maybe things'll turn out fine. After all, mares dig giant robots...right?

After being defeated by Cadence and Shining Armor, Chrysalis was stripped of her newfound strength and completely starved of food. She awakens in a strange room bound to a bed by several casts and bandages. A young colt found her near his home and tends to her while she recovers, each day bringing them closer and closer.

Can the Queen of Changelings even have true feelings of love, or is she just kidding herself?
