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:

It was never supposed to end like this.

Princess Cadance has saved all of Equestria from the changeling threat. What comes next isn't going to be half as easy.

One wedding may be cancelled, but a new engagement has begun.

Massive thanks to my pre-readers/ideas tasters: Bronetheus and RK_Striker_JK_5. Go check out Night Errantry and Spanner in the Works for two great fics that are well worth your time.

Warning: This is an attempt to make the Cadance/Chrysalis ship work, without too much darkness (though there will be some), or it leading to an inevitable bad end. If you hate this idea, believe that Cadance ending up with Chrysalis is automatically a bad end regardless of circumstances, or just think it's plain impossible to pull off then please move on as this fic is probably not going to be for you.

Still if you want to see if this pretty cracky ship can somehow be made to work, and have some fun along the way, then this just might be the fic you are looking for.

If you still hate the concept enough that you feel that you have to hit the dislike button, then fair enough, but if you find something else objectionable then please post a comment, or basically I'm going to assume that you're just disliking the ship rather than the story and ignore you.

The Sex tag is there for some of the humour, some implication to off screen activities, and a few bits on screen that while are no where near the mature rating do push things somewhat compared to the rest of the fic. If you're wondering where the Comedy tag went I decided while I do believe there's a lot of fun and amusement to be had, I can see why it might mislead some readers as some of the events are taken more seriously that you'd expect from an all out comedy.

Shortly after leaving the Crystal Empire castle to live a more humble and ordinary life among their subjects, Princess Cadence and Shining Armor decide to have a foal. Instead, they get two, and they couldn't be happier. They tried.

Skyla is a normal, if very hungry, alicorn filly. Her sister Inova is a reborn human, though nopony knows that, not even herself.

This is a substantial rewrite of the original story, with some new scenes, better writing, and a few things removed as well. Chapters will be released when they're good and ready, instead of evil and unprepared.

This story is a sequel to I have Zero Attack Power, Yet I Must Fight

At the whims of a strange, extradimensional being, Xathrid and Nan must defend the universal constant from attacks leveled by every villain in MLP:FIM. Can they succeed? Does this sound convoluted? Read and find out!

I Have Zero Attack Power, Yet I Must Fight
Mother Of All

On that fateful night on the moon, the princess of night is truly no more, and from those ashes, rises a new entity that is forced to take over her mantle, all her good and her sin.

Destiny weaved by the harmony itself laid before her. A part of the grand story, to be a tutorial villain, to be an exposition giver's sidekick, and to be slaved away beside the golden throne, then retired to a hut in god knows where, lost in history.

"Fuck that I'm out"

And so begin a new tale.

1. Half of "dark" tags are there as precaution because i will skimps over a bit but very rarely. for example Non-consensual will be use one time on no-name one-time oc character in a flashback. as far as i planned currently.
2. This is my first time writing a long novel. I promised to post the full plot outline somewhere if I somehow unable to finish it.

Warning: This story and this description both contain spoilers for the Web Novel: Worm. If you don't want to be spoiled, read Worm first, then come back and read this

The apocalypse had come at the hand of a god-like multidimensional alien entity. Taylor Hebert, a parahuman with power over bugs and bug-like things has her powers altered by a former enemy and subsequently uses morally questionable means to make everyone in existence with superpowers fight this evil deity, eventually defeating him.

This however came with a cost. Her mind was deteriorating as her power was subsuming her. Thus another cape decided it would be a mercy to put a pair of bullets in the back of her skull.

Another entity witnessed all of this. This entity, grateful for Taylor's role in stopping this alien god and thus saving countless worlds and thus countless lives, decides to intervene. It brings Taylor to Equestria turning her into a Changeling Queen in the process.

(Warning, Dark, Death, and/or Tragedy may be added to the list of tags in the future, depending on how things go. Furthermore, the Suicide tag is for the references to suicide in the description and in the first chapter. Suicide and/or self harm will NOT be a major theme in this story.)

(This is a crossover with the web novel called Worm by the author Wildbow. I highly recommend reading it if you haven't, it's a really good story!)
