Celestia is trapped on Earth.
Not as a human. Not as an alicorn. She's a common horse, an Arabian mare, without her magic, voice, knowledge of the language - not even freedom, forced to work at a riding school.

What can a single Arabian mare do to get back to Equestria from this backwater European country? With only the mind of a princess and a pencil in her teeth, Celestia must find a way home.

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
(12/02 added epilogue to last chapter)

The nation of Equestria has been exploring their little slice of the universe for some time now. From launching probes into deep space, to landing ponies on the moon. Sending things beyond the grasp of their planet has become almost routine. However, with every mission into space, there comes a time when the voyage must end. What happens when Equestria experiences the end of a voyage that they didn't begin?

It's been twelve years since Applejack's ascent to her current status as the Earth Goddess, Princess Mara of Equestria. In that time, she's gotten quite used to her duties, be they ceremonial, executive, or judicial in nature. But when she's called upon to rule on a particularly contentious lawsuit involving some of the most obnoxious ponies from her past, the results may end up altering the very nature of Equestrian law.

This story is a spin-off of Blue Print's Appleverse, however, it's not necessary to read his stories first (though I do recommend them for a more thorough explanation of the backstory).

Applejack's life is turned upside-down after she suddenly inherits the full powers of a goddess. She insists that it isn't a big deal and that she's the same pony as always, just bigger. Meanwhile, everypony else starts making demands on her and placing expectations on the 'new princess'. When the constant stream of petitions and gawkers starts interfering with farm work, Applejack reacts a bit strongly. Luna, fearing the worst, is determined to rescue Applejack from corruption, further irritating the farm pony. Will Applejack accept her destiny, or is destiny what you make of it?

The Rainboom happens as it should, and a few certain fillies earn their cutie marks because of it. Except little Pinkamena Diane Pie, who went inside before she could witness it. Thus, she never left the rock farm.

That meant she wasn't in Ponyville to throw that party that inspired a runaway colt named Cheese Sandwich.

However, the two end up meeting in adulthood, and the broke wanderer Cheese takes a job at the rock farm, and works alongside the grumpy Pinkamena and her family.

My take on an AU, created upon realizing that Cheese Sandwich was indirectly affected by the Sonic Rainboom. And in case you're wondering, the whole eternal night thing goes the same way as the show (except a different mare--whoever you imagine--wields the Element of Laughter).

This story is a sequel to A Faded Touch of Blue

Saddle Arabia is a land of tremendous wealth and beauty, with a culture richer than its oligarchs could even wish themselves to be, and a history which safeguards the right of every citizen to rise as far as their ability can take them... provided that they were born correctly.

Moxie was not; she was born with an inquisitive, hungry mind, with shrivelled wings, and a mare. And now, despite finding a lonely oasis of happiness at her husband's side, a disease threatens to put her newfound life in jeopardy.
