Canterlot... For centuries, Canterlot was the shining gem of Equestria, the pinnacle of pony society. Now, it’s a reminder, a bleak and monolithic warning to the world. 

Changed by the chemical and technological poisons that plague the mountain, an abomination of nature, I wander the greatest disaster Equestria has ever seen. 

... I will escape eventually, and when I do, I hope my friends still see me as Twilight Sparkle, and not the monster that hides among the ruins. 

To be inserted into Equestria, it's a dream come true for anybrony!

Meet the ponies!

Have super awesome magical adventures!

Use foreknowledge to avoid all those silly pratfall moments without screwing things up and causing irreparable harm to the Mane 6...uh...hopefully!

And all for the low cost of possessing Princess Luna, denying her any real freedom or the ability to move on with her life since she's in your head and you're walking around as Nightmare Moon!

Yeah...there had to be a catch in there somewhere, didn't there?

Four authors, eight characters, one labyrinth and a lot of violence. Oh this was a bad idea. How was alcohol not involved?

Four (in)famous Wastelanders find themselves unwillingly pulled into a place controlled by the mad goddess Katastrofis. Along for the ride are four ponies, each with a connection to one of the Wastelanders. Their task is simple: survival. But with the terrors of the labyrinth and the fickle nature of its mistress standing in their way, do they have any real hope?

This is a collaborative piece, so give those guys some loving too. They're all great guys.

Ten years ago, the Griffon Empire opened a portal to a strange new world and tried to annex it. In the peace settlement that followed they lost control of the province containing the portal. Since then, the Griffonian Democratic Republic had been completely isolated, surrounded on all sides by a hostile empire. Now, for the first time, a visitor had been allowed.

Twilight Sparkle - magus, heroine and Princess - has learned of worlds overlapping Ungulatia in space and time. Though this has been a well known phenomenon, safely traveling to these other worlds has always eluded pony mages. But now - after years of research and careful experiments - she prepares herself for the most audacious of all experiments: stepping hoof on the surface of an alien world and returning safely! What wonders will she find once she walks through her magic portal?

This assumes that Equestria Girls never happened.

Shawn Spencer, psychic detective, is a thick-tufted boy genius who ice skates through life on polished blades of snarky eloquence. He has tested himself against some of the greatest criminal minds of his time and emerged victorious... though often through unbelievable luck and not a small amount of bumbling.

Now, he faces a challenge unlike any before. One that will test his mind, his sanity, and his adaptability as he is thrust into the midst of an unfamiliar world and the ponies who populate it.

The Mane 6 face their own challenge, as an old enemy, tempered in the crimes of a much harsher world than theirs, returns to Equestria. It is a challenge they are ill-prepared for and one that only their strange, new, alien friend can help them overcome.

They wanted a monster....So they will get one.

(It is one thousand words. Fimfiction is getting the count wrong.)

Following the destruction of the Collector Base, the crew of the Normandy-SR2 go their separate ways. One squadmate, an AI 'Geth' named Legion, is sent by the Geth Consensus to investigate the possibility of a Quarian attack. However, when Legion is discovered and forced to make an emergency jump through the Mass Relay, it finds itself in the most unlikely of places... Equestria.

At the same time, the ponies of Equestria are dealing with their own problems. A mysterious disease threatens to topple pony civilization, while tensions along the border are growing and could escalate into full blown war.

Join Legion in its journey in Equestria to both return to the Geth before the arrival of the Reapers, and to help the peaceful ponies who inhabit the world.

Now with an amazing YouTube reading by the equally amazing AShadowOfCygnus!

During its two year search for Shepard, the lone Geth traveled across the galaxy, exploring worlds both known and unknown. After a blind FTL jump to escape from an Alliance patrol, it found itself in a previously undiscovered system, a system without a mass relay and completely cut off from the rest of the galaxy. It touched down on one of the worlds, a garden-like planet, with the intention of gathering data on any flora and fauna that may have been present.

Instead, it made a remarkable discovery.
