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:

Twelve thousand years ago, humanity was driven into a war with an unknown enemy. Fire rained from the heavens and the sky turned dark as the sun dimmed. Acid poured from the clouds and a plague was unleashed upon mankind: A virus that caused men to turn on one another. A disease that forced man to fall to his knees and beg for mercy. A pathogen that ravaged man’s civilization.

And when humanity lost all chances of reconciliation, all hope of keeping their loved ones safe, they pulled the plug, three hundred souls left Earth while sacrificing their only home to the angel of the enemy.

In the twelve millennia since the Great War, all traces of humanity have been wiped from the surface of the Earth. In man’s rightful place now are a multitude of sapient species. For twelve thousand years, these animals have lived in peace and harmony, man reduced to nothing more than but a myth, a folk tale, a legend.

But word has spread across the countryside. Word of forgotten beasts that still walk the western wastelands. Creatures able to bend the world to their will without the help of magic. Creatures said to be older than time itself.

Teen for language, and dark moments. Character tags will be added as the story progresses

This story is a sequel to Anon Buys the Everfree Forest

Anon is here and still very much on his bullshit. While he now has the run of his expansive property, not only does he have to assure his sovereign soil receives proper international recognition, he now has a flock of citizens seeking his guidance, expertise, and wisdom.

Ah well, one out of three isn't so bad, right?

Art is once again by me, lol.

This story is a sequel to Redemption

Sometimes, events occur that take us on a completely different, and unexpected path. This happened to Ryan Williams one chilly morning, who took a stroll as a broken man and returned home as a father. But no one, man or alicorn, can ever claim to be able to know where our paths will take us, or even when they will end.

*Cover art isn't great, but I can't commission anything like the last story, so you're stuck with it, suckers.*

Elias Bright is a survivor. He has survived the end of the world. He has survived the deaths of his family. He has survived the death of all that he has built. On the run from a past that haunts him to his core, he finds himself in Equestria, a land of tranquility and peace. Elias now has a choice. Does he give up the only life he has known, that of a survivor, and settle with the ponies of Equestria, or will his past deeds come to drag him back into the dark past he has tried to bury?
