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.

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

Takes place in an alternate universe where Celestia and Luna used the Elements of Harmony to slay King Sombra.

Celestia and Luna are no more. The sun and moon have collided, and the heavens torn asunder in the aftermath of their final battle. The Elements of Harmony are missing, presumed forever lost. The fiends of Tartarus are on a rampage, and no one can stop them. And to make things perfect, the ruler of the nation of Boardor has decided to invade.
Desperate, Clover the Clever's last living student gathers together 108 virgin mares, in order to perform a ritual that will revive King Sombra. They succeed... kinda.
A human, in King Sombra's body, suddenly finds himself in an Equestria in a downward spiral with a bunch of technicolor ponies begging him to save them. Convinced that he's either dreaming, stoned, or insane, he tries to go along with it as best he can, although the voice in his head, a very angry voice with a hunger for conquest, crystals, slavery, and stairs, isn't doing much to instill confidence in his own sanity...

This story is a sequel to Daring DONE!

The princesses need to take a week off to argue about important issues.

Luckily, Twilight is there to rule Equestria while they're gone!

There's absolutely no way this can go wrong.

As it's a sequel to "Daring DONE!", Twilight Velvet is the writer of the Daring Do saga and our favorite Indiana Jones homage is still a fictional character. That's what the AU tag is about!

Things only go downhill from there.

The princesses gave their magic to Twilight to prevent Tirek from stealing it. As a result, they end up stuck in Tartarus.

Marvelous place, Tartarus. Really brings ponies together. The fact that things manage to go downhill here says a lot about the wonders of family and alicornhood.

Long ago Celestia imprisoned a powerful, dangerous entity. Too bad nobody seems to realize he's a harmless dope.

This story started out as a parody of the two stories Machinations in the Dark and Celestia's Prophet. You may wish to read them first to get some context for the first chapter.

Now has a tvtropes page!

This story is a sequel to Past Sins

Hearth's Warming is a time for friends and family to come together, celebrate harmony, and welcome the new year. Nyx is looking forward to just this as she rides the train to Canterlot with Spike and Twilight. She's going to meet her extended family for the first time and wants nothing more than to make a good impression. Yet, the sheen of the holidays can't hide the trouble caused by meddling grandparents, relentless reporters, and a paranoid uncle.

Pinkie doesn't tell ponies about Pinkamena and Surprise. The doctors said that they were bad for her, that they were a disease, but she disagrees. Sure, Pinkamena's a bit of a grumpy-pants, but she's still a great friend! She's often the voice of reason to counter-act some of the other two's crazier ideas, after all. Surprise, on the other hand, is a great prank-player, and always up for some fun. She's more like Pinkie, only more hyper. Both are great fun to be around, and they get on well.

Thing is, she knows that if she told ponies about them, then they would be dragged back to the hospital. And then be 'treated' again. None of them want that. Because of this, not even her best not-in-head friends know about them. The three of them have, for years now, been careful enough to keep the existence of Pinkamena and Surprise secret.

This has, of course, gone out the window now that Twilight is hammering on the door after overhearing one third of a conversation, with no sign of anyone else talking.

Hints of F/F shipping inside. Nothing will actually come of it here, though. Maybe in a future story.
