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:

In their desire to rid Equestria from the threat of Obsidian, the Order Triune reached out to a power they did not truly understand, a power perhaps more evil than that which they sought to end, a power from Beyond.

Such reckless actions come with consequences.

Collected here are the various omakes, bonus chapters and any other extra content from the Dresden Fillies series.

All of the following are non-canon to the Dresden Fillies series, except 'Ditzy Dream' and 'Obsidian Journeys' which are companion pieces to 'The Dresden Fillies: False Masks'. All stories containing spoilers will include a disclaimer.

This story is a sequel to The Dresden Fillies: Strange Friends

Almost a year has gone by for Harry Dresden since he left Equestria. He'd have written, but between saving his newly discovered brother and destroying a scourge of vampires he's been a little busy. Then out of the blue he receives a strange letter from Twilight asking him to return. With no cases at the moment he eagerly accepts, but his friends aren't the only ponies expecting him. There's been a lot of rumors since his last visit and some ponies aren't too keen on seeing him come back.

A sequel to The Dresden Fillies: Strange Friends.

Crossover with the Dresden Files. Sequel to Forever!

For his first task as the new Winter Knight, Harry must travel to the land of cute little cartoon ponies to stop a plot by the Order of Blackened Denarius that threatens both Earth and Equestria.

Warning: Includes massive spoilers for the Dresden Files series up through Ghost Story.

This story is a sequel to My Little Denarians

A year has passed since Harry Dresden, wizard-for-hire and Winter Knight, rescued Equestria and the Elements of Harmony from the clutch of the Denarians. Why wouldn't he jump at the chance to return to Equestria to visit his (very) colorful friends in a totally peaceful and uneventful vacation?

Because he's Harry Dresden, and life rarely lets things go so smoothly for him, when it's not killing him to death. And when things go wrong this time, Harry finds himself in a realm far, far more terrifying than Arctis Tor, Discord's realm, or the Outside:

High school.

Follow-up to "My Little Denarians."

Harry Dresden, Chicago's only professional wizard, accidentally travels to Equestria after being attacked in the Nevernever. Twilight is none too amused with their newest 'guest', but trouble is brewing. Somepony is planning something sinister and the mane six may need Dresden's help however little some of them want it.
