When Fluttershy received her certification as a fog specialist, she only wanted a plausible excuse to write off the expenses associated with her ground-based house on her taxes. However, when an accident in Cloudsdale sends a blanket of industrial-grade clouds rolling towards Ponyville, Fluttershy suddenly finds herself in charge of coordinating the response, mostly because she's the only fog specialist in the area. Can our heroine step up to the challenge at hoof, or will she risk facing the wrath of the Equestrian Revenue Service?

Collab with The Abyss (Chapters 1 and 2)

Proofread by Neko Majin C and edited by The Abyss (Chapters 3 onwards)

Twilight Sparkle has always ignored Hearts and Hooves Day, seeing it as just another normal day with extra chocolate and the occasional broken-hearted friend to comfort. But when Rarity convinces her that not having a date during the holiday is contrary to proper princess protocol, Twilight rushes to do everything in her power to live up to the expectations presented to her.

There’s just one problem, though: Twilight has never been on a proper date before.

After a few rather disastrous attempts to find a date in Ponyville, Twilight goes to her mentor in Canterlot in a last ditch effort in the hopes of finding the answers she seeks. Princess Celestia, however, may have something more for her than either of them had anticipated.

Everypony is her own worst critic, but few take it to the extreme that Derpy does. Still, where friendship and magic abound, a helping hoof is never far away, if only she'll reach out and take it.

Rainbow Dash's first sonic rainboom makes headlines across Equestria. Every reporter is out to cover the story from their own angle. Sometimes they get it partly right.

She’s going down in history. Maybe.

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:
