Inspired by Dogger807’s hilarious story, “Magic School Days,” here on FiMfiction. While there is humour (and tree-sap) in this story, that is not its only focus.

Wow, Sir Chaos Omega made a TV-Tropes page for the story! Thanks!

Published on the FiMfiction website with the kind forbearance of the copyright owners of My Little Pony (Hasbro) and the Harry Potter series (Scholastic Press).

The timeline for “My Little Pony” is messed up. That is, if you look closely, the order of the shows as aired is out of order of their logical sequence. Evidence: in Swarm of the Century (#10) we see the dresses that Rarity makes in Suited for Success (#14) — so unless Rarity time-travelled, #14 should take place before #10! Also, in The Ticket Master (#3), the other five seem to know Twilight and Spike quite well, yet in Boast Busters (#6) they don’t seem to know Twilight at all.

With careful attention to details such as those, you can put the three years of episodes prior to Princess Twilight Sparkle (#65, Season Four) into a two-year stretch of time. If you work hard enough, you can even squeeze them down to one five-season stretch of Summer to Summer.

I used the two-year seven-part timeline mapped out by deviantart’s tobyandmavisforever (do a Google search for “tobyandmavisforever mlp timeline” as the fastest way to find them). Thus, Harry arrives in Equestria shortly after the Crystal Empire two-part episode, and Twilight and Spike have been in Ponyville just under a year even though the Crystal Empire episodes start the third year of My Little Pony.

While on her way home from a day with her friends, Apple Bloom runs into Twilight on a trip to Zecora's hut. After insisting to join her, little Apple Bloom gets lost in the woods after chasing a mysterious mare hiding amongst the poison joak. She stumbles upon a town completely isolated within the Ever Free Forest, but something about this town just doesn't feel right...

Many have opposed Celestia and all of them have fallen, one way or another. Some she has slain. Others she redeemed. Her servants and friends have done great deeds in her name and her fame has spread throughout all of creation. She is the Sun in all of its glory.

And yet she finds that she cannot get a single child to believe she is even real.

Part of the Monophysite Quartet.
Ageless, Or Celestia Plays Dice With the Universe, Have You Considered My Servant, Twilight?, and The Esoteric Rites of Darkness (NSFW), all coming from a single story idea called "Monophysite" and exploring some perception/idea/theory about who or what Celestia is and how that effects her friends and loved ones.

This story is a sequel to Past Sins

In the wake of the battle with Tirek, Twilight Sparkle becomes fixated on restoring Golden Oaks Library. After all, it was home for her little family of three. But as her attempts to repair the books and tree continuously fail, her friends must take matters into their own hooves. Discord, as the good friend he is, tosses Twilight and her extended family into an unexpected adventure while Twilight's other friends get to work on the new crystal palace.

All together, they'll do everything to ensure Twilight and her family have a place to call home when they reach the end of the road.

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:
