A changeling gets a very risky and clever idea.
Pretending to be an advanced magic doll left as an anonymous gift in front of Twilight Sparkle's home.
It's so audaciously stupid there is no way it's not going to work.

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?

A three arced story that begins slowly as partially Comedy and Slice of life and rotates more towards Adventure and Dark in later chapters.

Some school fillies have to deal with school crushes. Others with bullies. Sometimes they have to deal with both. But no filly has ever had to deal with an Evil Tyrant being bound to their shadow and have the power to control their every action. This, of course, seems to be no big deal for Sweetie Belle who seems to even enjoy the stallion's company. Though the feelings aren't mutual. The small filly reminds the old king too much of a filly he used to know... Though it's strange the only place he'd seen her before are in these strange dreams of his. Recollections of a past he can't remember.

Perhaps Sweetie Belle will awake in him that version of himself before he was a Tyrant. Before he was labeled evil. A time from when he was a father. Perhaps she will help him forgive.

In the far reaches of Canterlot Castle, high above in the towers lived the archmage. Everypony knew her, yet few had met her.

Twilight Sparkle sighed, having teleported away another noble seeking favors before reaching the top of the stairs for the second time today. They never learned. As the archmage, she already dealt with political squabbles far too often without inviting them into her home. Aside from personal favors for Celestia, she did what was required of her position and then returned to seclusion and research.

The nobility grumbled that no archmage should be a commoner, and Twilight’s disrespect toward them proved it. Each and every time they were forced to bow to her, they hated what they saw: the position, the status, the deference.

Was she not powerful? Was she not great?

Twilight, now reading through dusty scrolls and long forgotten tales, wrote in her notes — notes gathering dust of their own. A brief thought flashed through her mind.

Am I not powerful? Am I not great?

And then Twilight picked up The Tale of the Royal Pony Sisters.

Defunct side stories told in Across the Boundary. They can still provide a little context, but when in doubt, the main story here is canon.

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.

Many years ago, shortly before the birth of one Twilight Sparkle, Celestia, ruler of Equestria, found a small item in a forest. That item? An egg. Around the same time, in another place, Celestia, ruler of Draconica found something small in a forest. That thing? A pony.

This story is a sequel to Nigel M Chalmers, Emperor

(15/10/2015) Turned status back to incomplete pending an Epilouge and Alternate Endings chapter as per comment suggestions.

After being banished by Celestia for his misdeeds, the alien Emperor of the Crystal Empire is back... and out for revenge.

Emperor Chalmers is not a happy space man. After being stabbed in the back by Equestria, he was sent to the depths of the Underworld. Kicked out for causing too much trouble for the wardens, Nigel now has the chance to take back his empire and show Celestia just how disappointed he is with her.

This time things will be different. This time he has friends.

Disclaimer: Not a real-life religion, so there's no need to get all up in arms over a fic with the 'comedy' tag.

Post-Conversion Earth is a calm, peaceful place. However, it lacks the certain kind of chaos that only religion can bring. Enter a single, fanatical human from space to dish out his own kind of conversion.

Religion is coming to Equestria, brought by a single, oblivious, fanatic. On a divine mission from his God (at least that's what he thinks), this lone human will not rest until he saves the souls of all. With zeal in his heart, a holy tome in his hands and unyielding faith, he shall bring the true meaning of conversion back to Equestria.

Whether the ponies like it or not.

So grab your prayer beads, strap on your finest missionary boots and prepare for a preachin' you won't forget.

Arse-covering:
1. I'm not taking any shots at religion here, it's a shame that I have to point that out but better safe than sorry.
2. Any references to actual religion is purely for comedic purposes.
3. Not a hate-fic, I just can't resist the pun.
4. Disregarding the above points is considered heresy, and punishable by eternal damnation.

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?”
