Twilight just wants to sleep; unfortunately for her, not only is Celestia in a playful mood, but Luna is itching for some quality time. Shining Armor and Cadence then show up, and it turns into tug of war with Twilight as the rope. The prize? Spending quality time with everypony's favorite purple alicorn.

This story has Twilight/Celestia and implied Twilight/Luna. Also, Cadence has a very... vivid imagination.

Now a plotless(okay, so there's a bit of plot. Just a smidge, though.) ball of comedic fluff with multiple chapters.

This story is a sequel to Inexcusable

She looked just like Princess Celestia, except marred and broken. Her ceremonial barding had rusted slightly, and dirt matted her coat. Most noticeable was her hair; black streaks accompanied its usual multicolored luster. They looked like discolorations in an old photograph.

Worst was the scar across her chest. Her armor covered it, but nothing could hide what it meant.

The tarnished Celestia smiled at Luna. "H-hello, monster. I would say I am glad to see you, but that w-w-wouldn’t be quite accurate."

Sunset was enjoying her day, going through school as she was expected to do, when she's suddenly called to the Principal's office.

Confused, but with little choice in the matter, she answers, heading to Celestia's office. There, she finds the Principal sitting, wanting to have a chat.

Sunset was not prepared for anything like this.

Now with Youtube reading!

Diplomacy, foreign relations, cultural exchange, all important duties that Twilight needs to learn as a princess. Fortunately, this foray in to the unknown is made much easier when she meets a lovely foreign pony from the French Equestrian Kingdom who's willing to be friends with her.

Now, if only they could actually understand each other.

Series of oneshots set in a RariTwi AU based on the prompt, "Rarity and Twilight are princesses from different countries, smitten with each other despite being unable to communicate".

In the magical land of Equestria, two alicorn sisters raise the Sun and the Moon every day to give the world a night and day cycle, basic for the survival of life. There are also two alicorns who rule over two very core aspects of life and harmony itself. Those are Love and Friendship. While not as ancient as the two sisters, all princesses are essential to the world's balance.
This balance is also sustained by the hard-working ponies, who make the seasons change and manage the weather to fit their needs, so everypony has enough food and water, and every animal is also attended to assure that any of them are caught in the changes of seasons.

But what about the planet itself? What about Mother Nature?
This is the question that Gaia asks when she arrives to this foreign world. After so much work her son persuaded her to take a long vacation in Equestria, saying that she needed one and assuring her that he would be in charge now, and she must take a break. But what can a several billion-year old alicorn possibly do to pass her time in this land?

Celestia's morning has been difficult enough, between hearing Twilight's confession of love, and then breaking her heart as gently as possible. Mere moments later, her private chambers are rocked by the shockwaves of a time-traveling spell. This marks the arrival of Celestia's alleged lover from five thousand years in the future, Princess Twilight Sparkle—or as she insists on Celestia referring to her, Glitter-Flanks.

Armed with thousands of years of knowledge of which buttons to push and how to make her squirm, Glitter-Flanks has traveled back to this date for one singular purpose: to establish the closed time loop that sets the two of them up as a couple.

Twilight Sparkle has too much magic, and it will take her decades to learn to control it. Her spectacular loss of control during her entrance exam only proves that fact. She is a danger to herself and others.

After Sunset Shimmer’s disappearance, Princess Celestia needs a new student to bear The Element of Magic to defeat Nightmare Moon. With all of Equestria at stake, Twilight Sparkle…is not the pony she needs.

Princess Celestia seals Twilight Sparkle’s magic with the distant promise of one day teaching her.

But there are two diarchs of Equestria. Amidst a lucid dream, an offer is made.

“Hello, Twilight. Would you like to be my student?”

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.

Celestia was always a "family mare". She always held up families as one of the greatest social institutions in the country. She is famously good with children. All of Equestria looks to her almost like some great parental figure. But for some reason she has always been childless herself.

Perhaps it's time to change that. She is, after all, married to the most wonderful mare she had ever known.

Only a few hours after she learned of the Griffon Empire's invasion, Princess Celestia surrendered herself to the griffon army and asked for an audience with the Griffon Emperor.

The Emperor thinks she's here to negotiate Equestria's surrender.

He's wrong.
