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.

When the guards find a foal crying in the city streets, they bring him to Celestia's attention. Soon after, It becomes apparent he has fallen through every crack in Equestria's society. Feeling she has failed the colt, Celestia takes him into her own home.

Special thanks to my editors: ersmiller and Rinnaul and to my comrades in crazy ideas Exelzior and BionicBrony.

In the aftermath of her battle against Tirek, Twilight Sparkle is unwell. She wants more. She needs more. And she is afraid of what others might think of her.

But even in the midst of her growing despair that she has betrayed everything she stood for, she learns something about friendship and what it means to be an alicorn.

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

Magic is supposed to be controlled, released when the caster wants it to be and in the form dictated by the spell. To Twilight's glee, she succeeds in creating a spell to see a short distance into the future after many hours of research. The test doesn't exactly go as planned, but it works just in time to save a stallion's life. As she tries to reach out to a pony who she finds has nearly given up on life, she finds to her surprise, wonder, and concern that not all facets of magic are explainable, nor the workings of the heart - especially one that has been broken.

First story in my series. Currently undergoing a massive edit, as there were a lot of errors. Chapters 1-16 completed on the edit thus far. The endings are slightly un-canon, and that will be fixed by the edit, but until I get that up, take comfort in the fact that the shift has no bearing on the rest in the series, which currently follows the alternate path. Chapters 21-24 will likely be edited the most, as they were, admittedly, kind of rushed.

Oh, on a side note, I wrote this whole thing releasing a chapter a day as a personal challenge. Not my best piece, but the one that started them all. Ending one is blatant gary stu, I'll say it now. Art by askheroichamburger of DeviantArt

Twilight Sparkle, a ward of the crown ever since she accidentally turned her parents into plants, is dispatched by Queen Celestia to the small hamlet of Ponyville; the Unicorn has expressed fear that an eldritch Alicorn of the past will arise there. And when Twilight Sparkle fails to defeat the fiendish NightMare Moon in the two Queens' former palace of Concordia Arbos, the planet is plunged into night on one side and day on the other. With only shards of rock to her name and a band of ponies at her side, she sallies forth to bring back the Sun. She will traverse field and mountain, desert and labyrinth if she needs to. Will she be able to solve the mystery of the Elements of Harmony? Who was NightMare Moon, and what evils come to Equestria apart from her everlasting night? And why does Queen Celestia believe that making friends takes priority over everything else for Twilight...?

Scootaloo's settling in to life with Rainbow Dash. It's smooth sailing from here right?

Once again this story wouldn't be possible without the pre-reading and editing efforts of:

So if you like this, go give them a thumbs up.

You probably don't need to read Promises to understand what's going on, but it would be useful.
