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.

This story is a sequel to Equestria's Twilight

A side story to Equestria's Twilight.

I know I'm not really her. Celestia is dead and gone. But I feel like I'm her, even though I'm not even a real pony. Twilight needs Celestia, so I will do my best to be Celestia. An Equestria's Twilight Side Story.

A supplementary, but non necessary story to accompany Equestria's Twilight designed to further explore the character of Ailestia / CelestiAI. Chapter titles will reference the associated Equestria's Twilight chapter.

This is the story of the end. This is the story of the death of Equestria. It is the story of the reign of her royal majesty, Princess Twilight Sparkle of the Fading Sun.

The alicorn sisters are dead and Equestria has turned to Twilight Sparkle to guide it. However, just maintaining a dim sun a fraction as bright as her mentor's keeps the new princess near her limits.

Years have passed and Twilight Sparkle is sure of only one thing. Equestria is dying.

NOTE: Written before "It's about Time" in season 2. Everything after "Read it and Weep" was ignored throughout this story.

Everyone is dead. She doesn't know who is responsible, just that somepony activated the ultimate weapon. Only four ponies survived and now try to find meaning in the great wasteland. Celestia will just be happy if she can find a way to heal Twilight.

One day, Applejack was petrified by a cockatrice in the Everfree forest.
It was a long time before she was ever revived.

A story of moving through lives and the bonds forged in-between.

Was begun before the season four finale, so disregard anything in canon relating to Tirek. He does not exist in this story's timeline.
