This story is a sequel to The Art of Rainbow Engineering

Following Twilight Sparkle's explanation of the scientific method, Diamond Tiara asserts that the sonic rainboom is a scientific phenomenon. Scootaloo insists it is magic. The Ponyville schoolhouse is the scene for an unprecedented intellectual dispute.

It's a sonic rainboom. How not scientific could it possibly not be?

A side story to The Art of Rainbow Engineering - you don't need to read that first.

Can you make a rainbow just with sunlight and water? No magic required? With the help of the pegasus weather team, Rainbow Dash and Twilight Sparkle investigate.

Windfall takes place seven years after FiM's main timeline. The Elements of Harmony have gone their separate ways, but are still close, and all the girls come running to be there on the eve of Fluttershy bringing her first foal with Big Macintosh into the world.

If you enjoyed this story and this fanfiction future extrapolation, please consider reading the sequel Earth & Sky

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:

The truth is revealed! From award* winning writer of such academic essays as “Soylent Green is Ponies” and “An Abhorrent Offense: Princess Luna and the Invasion of Privacy”, third year University of Canterlot student, Loose Change, has finished her magnum opus, uncovering the secrets of Equestrian history, spanning from the Pre-Equestrian Age to the rise of Princess Twilight Sparkle.

Famously noted for causing her professor to laugh so hard he broke a wing while marking it, this revisionist abuse of history reveals the true lies and untold lie-truths behind the reign of Celestia, and Equestria as a whole.

This story is a sequel to To Sleep, Perchance to Dream

When Rarity receives a commission from Princess Luna to design a new “Look” for the Night Court, she didn’t expect the job to include Luna’s own Hoofmaiden and one of her Night Guards for protection. Could Luna have an ulterior motive in sending two big city Nocturne pegasi to small town Ponyville, and would it have anything to do with Celestia’s new hybrid rosebush “Cupid’s Delight” or Luna’s new interest in genetics?

Adventures in fashion, love, and romance that unfold like a kick to the head with the two most hapless Night Pegasi ever to work for Princess Luna.

A stand alone story that can be easily read without the previous appearances of Laminia and Pumpernickel (in chronological order below):
To Sleep, Perchance to Dream
Two Unicorns Walk Into a Village
Genealogy (or the Mating Habits of nocturnes pegasi)
Diplomacy by Other Means
The Empty Crib

I would like to extend my thanks to AlicornPriest, an amazing editor who edited this story while being up to his neck in fanfics and overloaded, AND carrying on a full time college workload in the Real World too.

The source document for this story is stored here if you would like to comment directly on certain spots or point out grammar misteaks/tpypos in my otherwise perfect writing (Ha!). We’re glad to have you over and I hope you enjoy yourself.

After receiving an urgent letter from Pokey Pierce, Big Macintosh seeks answers on his own as Pokey and others try to find their way through one of life's greatest challenges: lurv.

A silly shipping story with a slight hint of the macabre.

Now with more edits!
