Pandinus Imperator (You can call him Pan, he won't mind) is knocked back in time during the Canterlot Invasion, and accidentally kills King Sombra on arrival. Instead of being executed, the changeling is surprised to find himself being hailed as a hero, and is promptly put on the throne as the new monarch, the Crystal Emperor. However, Pan now faces a great many problems, among them Celestia and Luna, who seem certain that the changeling is secretly up to no good, as well as several political factions secretly plotting to undermine his reign. There's also the tiny problem of the constant snowstorm that threatens to cut the city off from the outside world permanently.
The Crystal Ponies need a hero now more than ever before. Why did they get a changeling instead?

We Has A TvTropes.

While not truly a part of Bucking Nonsense's Changeling-Verse, the same rules regarding changeling abilities and society apply.

There comes a turning point in every civilization where the future is dictated by the smallest decision.  Be it the will of a king or the cascade of changes by a commoner, it rarely matters the source, only the outcome.  So it was that, shortly after banishing Nightmare Moon, Celestia envisioned a world that could have accepted, loved, and embraced her now lost sister; an Equestria that had to cast off the simplicity of agrarianism and stanch traditionalism.

Instead of relying on the old ways as a bedrock for the six tenets of harmony, Celestia pursued this vision by lauding the advancement of magic and technology.  Over the centuries, cities of marble and stone were replaced by steel and glass. Family farms commercialized, business and trade expanded the world over, and the streets brimmed with cars.  The nobility long since traded away the power backed by titles for influence via companies. Megacorporations now dominate the skylines of every Equestrian city, yet Celestia still holds fast to the reins of true power.  Her word is law.

Even centuries after Nightmare Moon’s banishment, harmony is still in the bedrock of Equestrian society, yet one must dig to find it under so much soil and refuse.   There have always been those that chafe against the law and give lip service to harmony. Be they the rich and powerful figureheads of industry, or the scum of the underworld, there are always things these ponies in power need done discreetly, or at least deniably.  Sensitive matters such as these are often handed over to a class of professional criminals as diverse in their skills as they are in their ideologies. The Shadowrunners.

Note: As with my Beyond Equestria story, I am taking a lot of elements from the Shadowrunner series, but it will be written so that anyone unfamiliar with Shadowrunner can understand what's going on and enjoy the fic.

Ever since Tirek's rampage, Princess Twilight Sparkle has been working tirelessly to expand the Equestrian Earth Exposition of Trades and Magical Arts to Ponyville and to the general population. In order to bring out all the lost, ancient arts and magics of Equestria that could have helped in the troubles of the last few years. It's a symbol of peace, trust and cooperation between the Tribes.

But it isn't just the good that's come out of hiding, but the bad as well. And it wants all these arts for itself...

An OC heavy action drama. Give it a shot and please comment!

Equestria, the stellar empire long joined together with the Covenant has commissioned an inquisition into the crusade against Humanity, such a monumental task falls into the hooves of the diligent Twilight Sparkle. Granted the title of Inquisitor can the Unicorn bring herself to admit the terrible truth should she find it?
but more pressingly can she survive the deadly battle of Installation 04?

Twilight has a beard. It's, like, a really big deal for some reason.

Princess Twilight has seen some strange things in the past few years. She made the best friends a mare could have, she had some amazing adventures, became an alicorn princess, saved the world a few times, and got a palace to call her very own. Yet for all that, the strangest has yet to come.

There are new strangers in Ponyville. That's not too odd, but they're not ponies. They're human! But they're not like any human Twilight saw on the other side of the Mirror. Their magic isn't like anything she's ever seen, either. She'd love to learn more, but there's a problem. These humans could give Fluttershy lessons in keeping out of sight.

Dealing with snooping aliens was not exactly what Twilight had planned to put on top of her royal agenda.

I started writing this back before Season Five. It's not a new idea, not hardly, but no matter how many first contact stories I sifted through, always it was from the alien perspective. The pony perspective would come to the fore only rarely, and usually only with sizable external influences.

This story takes the idea of an alien observation team but is entirely from the locals' standpoint. What do you do when there's an alien science outpost next door?

This story is a sequel to The Witching Hour - Chaos is Change

Captain Midnight Storm of the Bearer Guard, tasked with protecting the Bearers of the Elements of Harmony, has her hooves full. Between dealing with new recruits, rogue ponies, and the whims of alicorns and her charges, it's enough to make anyone want to get away.

So what will she do when the things she's been looking for come looking for her?

Join Midnight, Sapphire, Squeaks, Windrunner, Honeycomb, and the rest as they make new discoveries, deal with old foes, and embark on a journey that will change everything for not only them, but all of Equestria in part 3 of The Witching Hour!

Rainbow Dash has been caught playing pranks again. Punishments haven't stopped her in the past, so Twilight and Starlight try a creative new solution.

It involves hypnosis and a Tulpa.

Also, she might get in on the hypnotist action herself at some point.

This story is a sequel to Undead Robot Bug Crusaders

Apple Bloom is an undead ghoul, but that's OK. She's finally come to terms with her condition, and is determined to rise above her curse.

Sweetie Belle is a robot, but that's OK. With manual in hoof, she's prepared to learn everything she can about herself, and whatever the future holds.

Scootaloo is a changeling, but that's OK. Changelings are citizens now, and she's ready to do her part to show the world changelings can be friendly too.

Together, the three of them are getting by, one day at a time. They may never get their cutie marks, but that's not going to stop them from having fun, finding their talents, and maybe even going a week without causing massive amounts of property damage. Maybe.

Meanwhile, Babs Seed is still blissfully unaware of the unusual destiny that awaits her, Diamond Tiara is slowly finding her place in the world, and Ponyville is still the weirdest town in Equestria. But then again, what else is new?

Unhappy that her future as a member of the monarchy is denied by Celestia, Sunset Shimmer escapes through Starswirl's mirror into another world, planning to take it over to prove once and for all she was fit to rule. What she didn't expect—besides a species change—was to arrive in a world already conquered.
