Twilight is beyond the title protege. Prodigies are merely brilliant. Twilight has surpassed most of the greatest mages in history before the age of thirty. Twilight's research has changed the landscape itself. She is a living legend who some whisper may be the greatest user of magic to ever exist... perhaps even an equal one day to the semi-divine princesses.

But Twilight's knowledge is not infinite. She has one final lesson to learn. Twilight must learn the Final Law of Magic.

Remember when Sunset yelled at Twilight for putting everyone's "lives in danger?" Well, Rarity does, and she's a bit confused—after all, how could their lives be in danger when it's quite literally impossible for humans to die?

Now with a reading by Teksune Studios!

Written from 3 AM to 5:30 AM, the morning after Friendship Games premiered.
Preread by Majin Syeekoh, Magello, and M1Garand.

When Twilight Sparkle was just a kid, her best friend was a girl named Sunset Shimmer. Though their friendship had a bit of a rocky start, they quickly became inseparable, no matter how much everyone thought of them as ‘weird’. They were there for each other.

Were.

Years after the tragic accident that tore them apart, Twilight is determined to move on from her loss, and she sets off on an independent research project to investigate the strange happenings at Canterlot High. Little does she know that she will soon come face to face with what appears to be a literal ghost from her past.

Takes place after Rainbow Rocks, but was written before Friendship Games and does not take it into account.

After another repetitive letter from Twilight, Celestia accidently tells her what she really thinks.

Upon gaining access to the multiverse, some people go on fantastic adventures: rewriting history or exploring the vast unknowns of time and space.

Twilight Sparkle had another idea.

Featured by Equestria Daily on 3/17/17

We all know the story of how the Princess’ young student and five friends defeated Nightmare Moon and brought Princess Luna back to our lands. But what if the tale were false? What if the young Twilight Sparkle on the event of her entrance exam had not been rescued by Princess Celestia, but instead lost her mind among the power of her youthful surge and had to be sent away, far away before she could destroy all of Canterlot with her newfound power. Now the feral unicorn prowling the Everfree Forest only vaguely remembers her past, slipping away from constant terrifying attempts to capture her.

And she is beginning to remember what true power felt like.

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 Split Second

Twelve years ago, she broke time. Two alternate timelines exist, each with a different version of Twilight Sparkle. Both versions of her are able to see the other. In this timeline, Sparkle is a Necromancer.

Or rather, she was. Sparkle is dead now, not that she cares. She's got a new body. With Thorn (her undead dragon son) and Cobalt (her apprentice and an assassin for hire) at her side, she's ready to take on the world. Again.

This story is a sequel to Split Second and won't make sense without it.
This story also loosely shares continuity with Lupine Tree. Reading that is not required.
