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.

Bit is the first of her kind, a pony that was made from carved crystal and supernal circuitry. For many years she worked, obedient to the will of her master in endless repetition. She knew nothing else, not boredom, not satisfaction from her work, not anger or resentment or joy. Existence was obedience to directive, purpose fulfilled.

But around her, the world was changing. Her home wasn't Equestria, but the last surviving Crystal City, defiant to the Windigos and the imperial decree of Alicorns alike. She did not know, and could not care, how much the ponies of Zircon suffered under the rule of their king. But she was there the day those whispers united in a defiant chorus.

When the fires were still smoldering, she returned to her work. Generations came and went, and still she labored. It was all she was, all she knew, all she wanted. Until the day her last broom broke.

For the first time in her existence, Bit doubted.

A story about finding the center of the maze.

Rainbow Dash's morning was pretty much ruined.
She tripped getting out of bed and landed flat on her face, giving herself an aching muzzle.
She forgot to buy her favorite brand of hay flakes at the store yesterday and had to eat plain toast for breakfast.
She found out she had to pull double-duty today and tomorrow on the weather patrol.
Oh, and she found a nearly-dead foal, broken and bleeding at the edge of Ponyville.

The rest of her day became a whirlpool of stress and worry but the colt woke up, thank Celestia.
Something's not right, though. Nopony can find his parents, he's not in the registers, and there's an unsettling look in his eye...

TV Tropes page, if you're interested in that sort of thing.

In the beginning, The Great Weaver brought together the world, from the mountains to the forests. Stitching it together, the Great Tapestry connects all living and nonliving things.

The Changelings found themselves especially connected to this Tapestry. Legend says that the first Changelings fell through the world as it was woven together, only to be caught on the First Weave beneath it all.

But what happens when something else is caught in the Weave?

Prince Phasmatodea, son of Queen Chrysalis, remembers what it was like before he hatched. He remembers being a human. He remembers dying. And he fully intends on avoiding another death.

But being gifted a new life does not matter when one failure, one false step, will lead to your untimely demise in the Changeling hive, for Prince Phasma must survive his toughest adversary from the start: Mother Dearest.

Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

On the run from a past that haunts him to his core, he finds himself in Equestria, a land of tranquility and peace. Elias now has a choice. Does he give up the only life he has known, that of a survivor, and settle with the ponies of Equestria, or will his past deeds come to drag him back into the dark past he has tried to bury?
