To Twilight Sparkle and Princess Celestia, it is a simple surprise visit to Canterlot. To the ponies of the Equestrian Civil Service, it is twenty-four hours of chaos, politics, weaponized dessert, politics, underhooved manipulation of media, politics, and things batrachian and tentacular. Who said bureaucracy isn't exciting?

Shining Armor decides he is Twilight Sparkle.

"If I hadn't blown the whole thing years ago, I could be flying up there right now. With her, with them, the Wonderbolts. But... would I be better off for it?"

After being expelled from the Wonderbolts Academy, Lightning Dust traveled around Equestria in search of herself. Then, many years later, after a hard day of working she went to a bar and ran into the last pony she ever expected to meet again.

Who is jealous of who, though?

Written for the Everfree Northwest 2015 Iron Author Competition

Twilight does some research into her tried and true teleportation spell.

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.

"She is our Shield, the benevolent protector of all ponykind. This was not always so. She was once a ghost, unfortunate enough to be forged anew in the fires of fate, and cursed to bear a sharpened edge that our foes would do well to beware."

Spiritual companion to Pest Control.
Review by the magnanimous PaulAsaran!

No one makes it through life unchallenged. For every person there comes a time when the world hurts them, betrays them, or calls on them for something great. It is in those dire moments that six mares will learn just what they are made of.

Sometimes the best medicine isn't for the body. It is for the soul.

[Second place finisher in the March Writeoff competition.]

An unknown curse has stricken Twilight, and nothing can get her to rise from her bed. As her friends wonder what to do, Princess Luna offers one possible solution: to send another into her mind. Down the rabbit hole into the mindscape they go, to learn more about their friend than many would have guessed.

Twilight Sparkle asks each of her friends, "Do you believe in God?"

This story is a sequel to If You Came to Conquer

Princess Nightmare Moon had tried to keep it secret. She had suppressed her power, feigned ignorance, played the outdated fool at every opportunity. She should have known that something like this would happen. A threat that would reveal her, whether she played dumb or not.

If she had to reveal herself, then at least she could protect Equestria in the process. She nocked the arrow. The bow felt so flimsy, but she could not risk him absorbing a spell. She laced magic across the arrow and the string and the air, enough to make it fly faster and aim smoother. She sighted him easily; Tirek was a large target. Now he only had to turn around. An arrow to the spine would kill him simply and instantly, no matter how much magic he had absorbed.

Once he was dead, the hard part would come: explaining herself to Celestia.
