Celestia is dying. Or at least it seems so. Afflicted with a curse that is destroying her very nature, she sets a plan in action.
The Bearers of the Elements of Harmony will take the throne in her wake... Not that they know that yet...

(Takes place as an Alternate Season 3)

Given the successful befriending of Discord, Princess Celestia deems that no longer will villains be defeated but instead reformed. While most have the chance to submit willingly or continue to fight, King Sombra is given little option. Brought back from the dead and stripped of all his powers and strength, it's all become a game of futility. Now Sombra only wishes he could have stayed dead all along.

This is a fic based on the Time Loop Files, the format of which was first codified by Innortal on fanfiction.net.
Here's a brief guide.
The basic idea is, one character (the Anchor, usually the main character of a fictional setting) is looping back to the very first moments of their parent series every time either they die or some kind of time limit expires. They of course end up monumentally stir crazy given enough time.
Eventually others start to loop as well.
The reset is not always perfect. Sometimes a loop's history will be different to the "prime" loop, or canonical plot.
"Crossover" or "Fusion" loops also occur, randomly. These can involve the home loopers having a guest, or the anchor for one universe spending time in another, or replacements of one character by another.
Vacation Loops are where the Anchor (or others) decide/s "buck it" and lets off steam by doing whatever comes to mind. There's little or no attempt to maintain the original timeline.

In addition, and particularly more recently, it should be known that this story has a collaborative element to it - people may submit loop ideas or loops, ideally at the Spacebattles thread (a link to the current version of which is on the Trope page), and they may become included.

There's two page image options, thanks to Filraen - the current page image has been edited by the original creator from this work of theirs.. The other one is here:

A few days after the Nightmare Moon Incident, Spike awakens to find Twilight acting a little...odd. Or odder than usual anyway. All of a sudden she's being all motherly, sure of herself in ways she's never been before, and even more outgoing.

But…it’s kind of creepy how she just seems to know everypony’s name, or their habits, and even some stuff nopony else should know.

But she's still good old Twilight...right?

After discovering that Cadence is not who she appears to be, Twilight is sent to another world entirely by the disguised Changeling Queen to avoid her plan being disrupted.
When Twilight lands, she discovers that not only have Spike, Owlowiscious and Peewee followed her, but that they've arrived in a world where the main sentient species is human.
There's still a place where they teach magic, though.
Crossover with Harry Potter. Twilight will be effectively taking the role of Hermione.

I've marked this story as cancelled to reflect the unlikelihood of it continuing. If I do come back to it I'll revert that.

For most of Applejack's life, she didn't know what she was. True, she understood who she was well enough.
But ponies don't change shapes, nor do they get strength from love.
Applejack never thought too hard on it... until the events of a certain wedding brought about some harsh realizations.
Now, with Equestria still reeling from the surprise attack, will Applejack manage to come to terms with what she is? Will she even be able to keep her secret safe?
For if the royal guards don't get her first, the conspirators in the shadows just might...
