Princess Luna, Mistress of the Moon, co-ruler of Equestria, is utterly bored, and tired of dealing with the bureaucracy. When she happens upon an uncompleted spell that promises access to other worlds, she finds a project that engages her as seldom before. Yet, some worlds are not so pleasant and safe as Equestria, and Luna is about to find out how denizens of one of the more dangerous realms entertain themselves as she is thrust into a bloodsport like no other.

The Tournament awaits.

A crossover with Unreal Tournament, specifically UT2k4, which I've come to regard as my personal favorite of the series.
There is some gore, but nothing worse than your usual FPS game made in the last 10 years or so. Rated Teen for that, and some foul language. (Because it wouldn't be UT without the smacktalk.)

Consider this as the soundtrack. Because that's exactly what it is.for Deck 17. So, freakin' EPIC.

Cover art commissioned from Atryl, who is a demigod of Art. Seriously, he's awesome. Go throw money at him.

The Ponyspawn have invaded Equestria, and it is up to the newest addition to the Grey Wardens, Twilight Sparkle, to find the means to drive them back! With her friends and allies at her side, can Twilight defeat the evil tide before all of Equestria is devoured?

The Sequel, Pony Age: Catalyst, is available.

The legends told of their return.

For over a decade Equestria has been beset by the dragons. Every year more villages vanish in flames, and the lonely cities stand as our last redoubt. Winter has gripped the world, and our hope is fading.

But the legends tell of another, a light in the darkness. The Dragonborn, a mythic warrior reborn with the power of the Voice, the only one who can stand against the dragons.

But when she appeared, she was not what we were expecting...

Blueblood just wants to run his charity and be left alone, but High Society - and starry-eyed mares - have other plans.

He's not a good stallion, but maybe he's a better one than even he would guess. Now if only he'd stop being so cynical...

The sequel to Wayward Courier. Read that first, or you'll get lost.

Two months after his first visit to Equestria, Thomas has returned. And this time, he's not alone!
Now the ponies have to deal with not only him, but a depressed snarky ex-Scribe and a Brotherhood Ghoul with her own list of incredible achievements and emotional baggage.
However, things aren't well in Equestria, as they quickly find out...

All major details relating to Season 3 are non-canon to this fic.

After a mishap involving the Transportalponder, the Courier finds himself in a place he doesn't recognize. With no way back and nothing else to do, he decides that wandering into the nearest town is the best option. Being the Courier, things aren't that simple...

A Fallout: New Vegas/My Little Pony: Friendship is Magic crossover

The style alternates between omnipresent third-person and the Courier recounting his tale to... Well, take a guess.

Coin Slot, a slaver in the Equestrian Wasteland, is making just a regular sale when something a few miles away explodes violently. Deciding to check it out, she discovers a strange weapon of unknown origin that seems to mesmerize its targets. There are... drawbacks to this weapon, however, and its discovery soon leads Coin down a chain of events that will change her morals, lifestyle, and even her very soul... provided that she manages to survive. Will the friends she makes be enough to convince her that her slaving ways are immoral? Or will they just reinforce the belief that that is one of the best ways to survive After the End?

A side story of Kkat's Fallout Equestria. Which is excellent.

Twilight Sparkle presents a collection of interviews, letters, essays, poetry and prose compiled over several years of her relationship with the human Bellerophon and his "herd", covering subjects as broad as Equestrian social taboos, comparisons of earth and Equestrian mythology, romance and the occasional recipe. Compiled by Twilight Sparkle, with foreword by Her Royal Highness, Princess Celestia.

(This is a bit of an experiment based on the worldbuilding concepts presented in AnonAuthor's Xenophilia [[NSFW] - caveat lector!], which intrigued me enough to want to take a closer look. It's likely you'll be very confused by this unless you read at least some of Xenophilia. Updates will appear as and when an idea pops into my head for a thing to add. And fair warning, some of this might come across very dry and dusty. Thank you academia! And thank you AnonAuthor for letting me have a go, and both AnonAuthor and AnonponyDASHIE for all the collab work they're doing. I'll make up for the dust by tossing in the odd piece of art now and then.)

IF YOU FAVE IT, LIKE IT!

A few days ago, RC-1207 "Sev" was pounding a Seperatist ship with Wookie turbolasers when he was overwhelmed. Now he's in a prison camp a few lightyears away. His cellmate is a male quadruped calling himself "Big Macintosh". He doesn't know where his brothers in Delta Squad are, or even where he is.

RC-1000 is the newest member of Tau Squad. Or was, rather. After the rest of Beta Squad was killed in action, he was assigned to Tau, who had just lost their own brother. They were tolerant but distant, and on his second mission with them the "new guy" got captured. Now he's sharing a cell with a female quadruped named "Octavia".

They're going to bust out. And as they try to adjust to the thought that they each might be the sole warrior on the planet, they will think more than a clone, even a commando, normally would. They will fight to defend their new friends. To defend aliens that care about them in ways they haven't experienced as mere soldiers.
