The world has been dying for as long as the Enchantress can remember, reduced to little more than a desolate expanse of sand. And yet, she keeps walking, for she knows she is the last hope of the world.

When mares from extremely different worlds arrive in her desert, the Enchantress is forced to reexamine everything she thought to be true. There will be stories of monsters, books, ghosts, gods, stars, machines, and ponies who have not lived most of their life in a world approaching the end. They must come to terms with their vastly different experiences in a tangle of alternate worlds no one is prepared for.

The multiverse is a big place, and this small corner of existence has just received some unwanted attention.

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:

The League of Sweetie Belles was founded by a handful of Sweeties who decided they liked hanging out with each other. What started as a simple club for like-minded white unicorn mares turned into a complex organization with a lot of responsibility. One particular team of Sweetie Belle explorers have taken it upon themselves to explore the multiverse, delving into the lands of ponyfics and beyond.

(If you're not reading from the beginning and just want to look into one chapter relating to a particular story, the SUPPLEMENTAL MATERIAL: The Sweetie Personnel Files blog is your friend. Refer to it whenever you feel you lack context. But don't read the entire thing; use it to look up names.)

(Part of the Songs of the Spheres continuity, but you don't have to read that to understand this. This fic can never never be complete due to its episodic and open nature, and it may never update again—but who knows? As with all SotS stories, there's a Discord server)

Warnings are there since certain fics will require them when they are included. You won't get sex, death, or gore everywhere. You are likely to get violence and some profanity in many chapters.
