And after a bad encounter with Trixie our protagonist Amber Wood has decided to stick around Ponyville.

This tale begins just before the start of the series.

Sunset Shimmer ran through the mirror seeking two things: an escape from Celestia, and a way to get revenge. Meeting up with these strange creatures called "humans," she can say with confidence that she has accomplished the first of her tasks.

Now a student of Mahora Academy, Sunset, or Nichibotsu Hikaru as she's now called, must navigate the overly eccentric life of class 2-A, all the while keeping an eye out for any signs of magic. After all, how is she supposed to take her revenge without...

Princess Celestia has sent an invitation to Twilight Sparkle and friends for a royal Canterlot wedding! While reading off the list of invitees, however, Twilight comes across a certain "Mrs. and Mrs. Dash". Turns out Rainbow Dash and Rarity are a married couple, and have been since before Twilight moved to Ponyville. Twilight never knew this. Hilarity ensues, as well as a few feels.

(AU, where RariDash are, well, married. Some canon events and scenes have been shifted accordingly, to Twilight's increasing confusion.)

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:
