Stranded on a hostile, alien world, Twilight Sparkle and Rainbow Dash must depend on one another and a fellow alien castaway if they want to return home to Equestria.(originally published on FFN)

Driven by an intense Warp storm, a Rogue Trader vessel finds itself crippled and stranded above a world no human has ever visited. The natives are friendly; can the visitors say the same? A Warhammer 40k/Friendship is Magic crossover. Yes, really

“You know how when you're at a party, and you use what you didn't realize was a magic letter to Princess Celestia to roll a joint?
I guess maybe that's not, uh, a thing, but yeah, I did that this one time. It was at that huge party Shannon and Adam had a while back. You know, Max's friends? …No, Celestia's not one of—They wouldn't know each other...
But anyway, yeah, in case you were wondering why I'm all like, a girl unicorn now, that was kinda the short version.”

Meet Rob, a 27 year old musician who gets more than he bargained blah blah blah
Get a front-row seat in his brain for the Long Version, as he wracks it trying to weasel out of being a pony, or at least not let anything slip by as he takes it one freaky moment at a time.

What will the other lost-weekenders think when they walk in on him passed out on their couch? Will he be able to get through the city and at least back to his apartment, if not to normal? Will he learn anything about REAL friendship along the way and stop being such an insufferable hipster? What if some blowhard fan author just couldn't “turn it off” and ended up trying to write a pony story as actual sci-fi? Will Ahuizotl get the statue? Does P=NPony? Can you grab me another beer while you're up?
And did that letter ever get to Princess Celestia?

Your standard pony Trip Report, with your standard pseudo-autobiographical narrator, written to flush out my creative plumbing and play around with, uh, like, good...thinkies and word-putting, and because the urge to do it just wouldn't leave me alone, so I just had to get it outta my system. I just really like the juxtaposition of humans and ponies, I guess.

Title is obviously a reference to M-Theory and Tristram Shandy, respectively. Because I can never pick just one thing.

Rated T for Adult Situations, gratuitous overthinking, and fuckloads of swearing. Oh and I guess drug use.

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

He was always considered an outcast, a black sheep. When his peers find his secret, that he likes to watch My Little Pony, they taunt and ridicule him for it. But, after a freak accident, he is taken away to the land of Equestria. Has he truly found his place? Oh, and he's an ork. That might be an important little detail. Warhammer 40k crossover.

Eighty years after the events of The Dread Chitin, Equestria is a radically different place. The arcane science of the late Duran Thirk and the information found on the Star League library core have combined to catapult the nation's science ahead by hundreds of years.

Now, facing the possible aggression of a completely unknown alien power, Twilight Sparkle and her friends have to gather together once more, leading a crew of the best ponies they could assemble in a voyage outside their own star system. They seek to learn about their potential foe, to explore the galaxy around them, and possibly find allies and friends to stand alongside them. Who knows what they will actually find?
