This story is a sequel to MLP Time Loops

The Infinite Loops (format first codified by Innortal on fanfiction.net). An endless recursion of time brought on when an unknown event happened to Yggdrasil, the World Tree computer that contains and runs the multiverse, forcing the various universes to be put in 'safe mode', time-looping until Yggdrasil can be repaired. Those aware of these Loops have been through much. There has been love, hate, loss, humor, and much, much more.

Now, in an event too large to be contained within the MLP Time Loops alone, one of the Loopers from Equestria's branch is getting married... to the Anchor of the Warhammer 40,000 branch.

This is the story of that wedding, and the chaotic events that come with it.

Author's note: Prior reading of the MLP Time Loops is heavily recommended. Spoilers for that fic abound, and associated terms will be used without explanation.

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:
