Diamond Tiara has always enjoyed picking on the Cutie Mark Crusaders. But one day, she finds she's gone too far, and everything for her comes tumbling down. But help may come from the most unexpected of places...

Started before season four, and does not take season four canon into account.

New Laws. Something that rarely happens in Equestria. Not for the lack of needing them, there are plenty of issues that could be solved with the right kinds of laws in place, but for the simple fact that a lot of times they just don't work out as intended and get revoked. It can be a challenge to find the right kind of balance between a law, the rules of the law, the enforcement of it, and the punishment that comes with breaking it.

A challenge that Equestria's newest Princess, Twilight Sparkle, feels she is up to the task for.

Twilight has seen and heard about many issues, both in Ponyville and other parts of Equestria, that could be handled with the right kinds of laws in place. However, due to there having been several times in the past where new laws being passed have been less than ideal, she is going to be taking it slow. To do this, any new laws she passes will first be given a trial run in Ponyville to see how they work out before either letting them be applied to Equestria due to being successful or being dropped due to not working as intended.

Twilight Sparkle is certain she's going to fail Celestia's test. So certain she casts a spell far beyond her capabilities. In a mysterious twist of fate and magic, Elsa and Twilight switch places. Can they manage to save both worlds in time?

This story is a retelling of the Season 3 Crystal Empire episodes and the movie Frozen.

An Optimalverse story.

CelestAI creates worlds. Perfect worlds, perfectly suited to satisfying the values of the pony living in them. Every pony is different, so every world she crafts is its own work of art.

And every piece of art tells a story.

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.

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:
