Twilight Sparkle broke time when she got her cutie mark. Now Twilight and Sparkle are sisters from another time. Twilight is hailed as the potentially greatest light magician of all time, and already has a reputation as a hero by the time she goes to Ponyville. This isn't her story, not primarily.

Sparkle is an orphan - her dark magic killed her parents. She lives with her brother in Canterlot's industrial sector because they can't afford anything better. She can't leave either. She's a natural dark mage; while Sparkle won't go mad like Sombra, her reputation is hardly any better. Worse, the law doesn't see her as a good pony.

The fact that the dead don't stay dead around her, or that Thorn - Spike's double - is an undead, soul-eating abomination, are other matters altogether.

(Also has some Slice-of-Life, but fimfiction tags won't let me put it with Adventure.)

Has an ask blog to go with it: Ask Sparkle and Thorn.
Also has a TvTropes page: Split Second Tropes.

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.

[Illustrated] [Alternate Earth] (without Bronies)
Rated Teen for language and some scarce suggestive themes.

Polish language version

When Gaberdine is awarded a noble title by Princess Celestia, he soon finds out that his new lands contain several surprises. For starters, there is no land in his new barony. Secondly, his new castle turns out to be a broken-down riverboat. And third is… seaponies.

Baron Gaberdine has a lot to learn about his new barony. And himself.

Fortunately, he has a very young teacher.

Sequel can be found here: http://www.fimfiction.net/story/306592/normal-life

For seven months I've been with one of the best girls imaginable. We're living together, we're doing well in school- I'd never believe I could ever be this happy.

I also could never believe that, on the night of my 25th birthday, I would look in the mirror and see my hair and eyes turning green.

Nor would I believe that, within the next twenty-four hours I would turn into the queen of a vampiric race of insectile monsters from a cartoon.

Go home, evolution. You're drunk.

(Set in the Five Score universe. ...What do you mean there's already a Chrysalis Five Score story?!)

Fair bit of swearing.

King Sombra survived his defeat, but just. By the time he returned to form, Twilight became the newest princess of Equestria and the Crystal Empire was restored to its former glory.

He cannot take over Equestria the same way he tried before, but he has a card up his sleeve. Twilight won't see it coming, and Sombra might gain a powerful ally in the process.

And it will all begin...with a book.

Major props to InuHoshi-to-DarkPen for letting me use this. That artist is really good.

Father used to always tell me that one of the keys to being a good ruler and an organized pony was to keep a journal. So, like a good little filly, I did exactly as he asked. Books upon books I filled up with random musings and other small tidbits of information that I didn't realize nopony would really care about.

At least until He came into my life. Suddenly, the journal I had never used too seriously took on a whole new meaning. It became my best friend, my confidante. Now, it is a way to remember the good times after so many bad.

My name is Cadenza, forever branded as the one who lost the Crystal Empire. This journal is both my warning, and my confession.
