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.

My name is Twilight Sparkle.
I am three hundred and seventy five years old.
Except for Spike, all my friends are dead...But not for long

Betrayed by Celestia, and isolated in her castle with only Spike for support, Twilight Sparkle enacts a powerful spell to reincarnate the element bearers through her own body.
Her friends will be reborn, and, with the trials of being a mother to her friends ahead of her, an unraveling secret from the past following her at every turn, and the possibility of a brand new life so close in reach, Twilight just might be reborn too.

Just because the two sisters have led Equestria through thousands of years of peace doesn't mean there aren't those who think they can do better.

With a powerful artifact on their side, a group of rebels has sealed Celestia in her palace and stripped her of the majority of her powers. As the last of her guards fall, she hears the pounding on the throne room doors and knows the end is coming soon...

**Now with a dramatic reading!

A Metroid Crossover

A meteor, resistant to magical manipulation, crashes in Equestria, Planet Equis, and soon spreads an unknown poison throughout the land. Containment is all but failing and the Princesses have little power to stop the spread of the Great Poison. The Elements of Harmony are of little use as no knowledge exists of this threat that consumes all life. Help comes from a certain Hunter, clad in metal.

Samus Aran will not only fight for her life as always, but her own sanity as well as these ponies that she begrudgingly starts seeing as allies. New horrors and abilities await her as a reason to fight slowly festers within her, possibly unlocking something she had been denied for so long: Friendship.

Notes and Resources:

This takes place after Echoes. The events of Corruption will have not happened yet. In terms of MLP, consider everything up to and including the Crystal Empire. Princess Twilight does not exist here, etc. The official Metroid Timeline can be found here.

As well, this story references the manga in many places. Reading of it is not required and I try my best to explain the context, but if you're interested, both volumes can be found here.

EDIT: This story was written over two and a half years, beginning in 2013. You'll probably notice the difference in writing as the chapters progress.

Princess Luna still feels alone, nineteen years after her return to Equestria . But when she finds a friend in an online game, everything seems better. She can be herself without worrying about what others think, and she can finally talk to another pony, even if he never knows who she really is.

Celestia is worried about her sister, especially right now. Upcoming peace talks with a powerful new nation mean that all the Princesses need to be completely ready. With her Luna so absorbed in a fantasy world, she wonders how she'll make it through the harrowing weeks to come.

Button Mash feels like a failure. He's still living at home, he still can't find work that can use his degree from the university, and he still feels alone. His friends are getting married, starting families, and thriving in their careers. On the plus side, he plays games regularly, and his best friend is a mare, even if she doesn't know his name. He hopes that his upcoming vacation to Canterlot might help his mindset.

But, unbeknownst to all of them, a sinister web within a dark plot threatens to ensnare Equestria... And Luna may be the only one able to stop it.

She may face it alone, or maybe she'll have some help from her knight in faded armor...

Follows canon up to about season 4 or so. I'm not sure when everything went off the rails, but it was originally as true as possible when initially written.

Rainbows at night. Strange apparitions in the sky. Seismic disturbances. Bizarre rumors.

No doubt about it...there's definitely something strange going on at Canterlot High School.

Twilight Sparkle is determined to get to the bottom of this mystery.

But are the Rainbooms ready to deal with this Twilight Sparkle?

When five foals asked Princess Twilight Sparkle to please try and paint the moon purple during Nightmare Night, she initially refused. It wasn't until they insisted (and Princess Luna quite basically dared her) that she relented. She only relented, however, because she really thought she wouldn't be able to do it.

Too bad she thought wrong.

A very silly story that started as a prompt that got way, way, way out of hand.

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.

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?

Jon Stewart needs to find a way to get more people to watch his show. To do this he welcomes a new series of guests from a far off land containing monsters, magic, and most importantly... ponies!
Join him on an adventure that has him matching wits with sentient mythical creatures ranging from god-like ponies to a fire breathing dragon! Each "Episode" marks a different MLP character getting a chance to travel to the human world for an interview on The Daily Show with Jon Stewart.

Please feel free to leave a suggestion for who Jon should interview next.
Disclaimer: For proper context it is highly recommended to reach each chapter in order as many interviews allude to past guests and events.
