When the fillies sneak out of Twilight Sparkle's library on a stormy night, Princess Luna must convince them that adventures are often found closer to home.

In the aftermath of Discord, Equestria becomes accessible to the universe as a whole. When the USS Enterprise stumbles upon them, will they accidentally shatter the peace this world has known?

What would you do if you've gone where no mare has gone before, and have no idea how to get back?

Rainbow Dash found herself alone in a strange, magicless world governed by entirely different natural laws than Equestria, ruled by a race who thought themselves the only sentient species in the universe...

In a universe where humans are quite shocked to find ponies that speak languages at all, let alone English, the startling discoveries never seem to stop for the poor crew of the SMS Verreiter IV, an old-warship-turned-exploration-vessel hybrid that's certainly seen better days. Heck, some even speak of times that it had days where all the systems functioned properly for hours at a time.

Either way, they're on a mission of exploration, which means they'll be visiting every Old Earth-sized rock they can find. With a motley consignment composed of few jittery scientists, veteran marines, an exasperated captain, and a combat-hardened, battle-forged crew with absolutely nothing to do besides repair their own ship from itself, it seems like it'll be a very long year of exploration.

Then they find a planet with some rather startling similarities to human society.

Like Manehattan, the apparent parody of the American district, ponies having developed the English language, and the use of human-like tools and buildings.

And when the ship's transmitter fails at the worst possible moment, Forschungsschiff Kapitan Arnhem Zorner has to decide how best to introduce his country and humanity to these beings. Who can levitate books probably as easily as they could levitate knives and hurl them at him.

He doesn't know whether to laugh of cry at the situation that's been thrown at his face.

Short story inspired from an amazing picture by Harwick.

Long years have passed, and Twilight Sparkle has outlived most of her close friends. As Twilight's time in Equestria draws to a close, Princess Celestia teaches her student a final lesson filled with cosmic revelations. (And yes, it does actually have a happy ending.)

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?

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)

It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.

It's funny how a random whim can turn out to cause the most profound encounters in a person's life. By attempting a bit of magic, I was able to get the once in a lifetime chance to talk with actual royalty! Only, royalty from another world...
