Reader, in ancient days, the old lords of the world numbered in thousands. Then hundreds. Then even less.
Now, they are found only in tapestries and fanciful ballads.
The creatures are all vanished. All but one.

Rumors say there are more of him, somewhere far away. A young and supposedly gifted mage called Star Swirl, and Heartstrings, a gentle spinster, have joined him on a journey to find the rest.

(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.)

Rated Teen for gore... rating may be subject to change, we'll see.
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.

Ponyville faced an ordinary day, but then night came, and with it a massive gateway into another world. It closes before any action can be taken, but now the Mane Six and Canterlot nobility are tasked with finding out what they can about the gateway. Who created it? Where did it lead to?

And most importantly, did anything come through?

Takes place after Season 2
Now 20% cooler with a TVTropes page!

[Eventually will be rebooted in a new story]

Rated [Teen] for F. Violence & Strong Language.

It's been ten years since she's been crowned princess, and during that time she's been rather... busy. Among moments of solving friendship problems and saving Equestria multiple times, she has destroyed the covenant, saved the Mushroom Kingdom and its princess, destroyed all the colossi in the Forbidden Land by the order of a sealed god, escaped Black Mesa, and many more heroic deeds. Yes, Twilight Sparkle can call herself a video game master of many genres. However, she never once touched the aspects of virtual reality MMO’s. That is until she started playing Equestrian Earth. With a whole digital world before her, Twilight felt that her adventures in the MMO would be her greatest adventure yet.
However, this adventure may prove to be the most dangerous as a powerful entity and its legion of hackers have taken over the world. Twilight Sparkle must unite with her fellow gamer friends if she is to prevent herself from getting a game over not just in the virtual world, but the real world. Adventure awaits in a land filled with monsters, allies, quests, rivals, imagination, friendship, and magic.

This is Equestrian Earth, let the games begin.

Ω SLthethird's review

Spike, along with Snips and Snails, discuss the more important topics plaguing the denizens of Equestria such as who's hotter to weird fetishes.

After an irritating encounter with Penny, Sheldon retires to his home-away-from-home, his Batcave, his Fortress of Solitude: his office. But the physicist gets more than he bargained for when a strange interdimensional worm hole appears in the Biology department.

Trapped in an unfamiliar, scientifically impossible world. Sheldon has the perfect opportunity to flex his astonishing social skills, or lack thereof. Completely oblivious that the fate of Equestria rests in his hands, Sheldon embarks on a journey of self discovery and love and tolerance... except he doesn't discover anything, and love and tolerance is a waste of time.

Well, maybe he'll learn the value of friendship along the way. But that isn't likely

THIS STORY IS NO LONGER BEING WORKED ON. THE IDEA IS UP FOR GRABS; PLEASE CHECK MY USER PAGE FOR MORE INFORMATION.

Humanity has had the urge to learn and understand since the dawn of their species as Homo Sapiens. From the first telescopes and the study of the stars by sailors, to the colonization of new worlds, Human beings have pursued the unquenchable thirst for knowledge in all of its forms, no matter what the cost.

Now, in the year 4025, long after Humanity began expanding their reach into the deep expanse of space, a new world is found that defies all laws of physics and reality...

Inspired by her many trips through the Everfree Forest, Twilight gets an idea for a book. With a little help from her friends, however, what began as a single passage quickly evolves into an entire universe, with the Mane 6 as its goddesses.
