When Twilight and Celestia have an argument about the existence of leap years, there’s only one possible way to settle their differences: a race around the world!

With the full benefit of hindsight, there may have been other ways.

An 80 Days crossover, written as part of Horizon's writing challenge. Edited by Ether Echoes, Soge, Giant Hat, and Tormented Dragon, who are all amazing.

Two weeks before the 1000th Summer Sun Celebration, Moondancer discovers a forgotten spell scrawled across the pages of an ancient book. Casting it threatens to turns her world upside down: faced with glimpses of an Equestria contradicted by historians, she must use all of her intellect to piece together the mystery surrounding Mage Meadowbrook, Princess Celestia, and the mare with the mane of stars—before the project destroys everything she's worked for.

It's a good thing she can rely on Twilight Sparkle for help.

Spanish Translation from Spaniard Kiwi!

A strange series of occurrences are plaguing the fine city of Canterlot, as one by one, a pony of vengeance strikes seemingly random ponies down in their prime. As the locals try to contain the situation, they find that it soon slips out of their hooves as they discover that this one simple pony might not be as simple as was originally thought. Once Twilight Sparkle and Princess Celestia gets involved, can everyone work together to bring down this threat that threatens to ruin the very core of Canterlot? These City Walls is an exploratory tale about character, relationships, mystery, and the very old, ancient powers that be. And once five innocent ponies get tied up in the lives of each other, a struggle begins to keep the entire city safe for future generations.

This is a primarily OC story. Yes. Run. Run in fear.

(A Firefly/MLP crossover.)

You can’t take the sky from me.

Those are ex-Sergeant Applejack’s thoughts when she buys a fyre-flye class transport ship. For those ponies who have lost the war that unified all worlds under one benevolent tyrant, there doesn’t seem to be anywhere else to go but up. With Applejack as captain, the scavenger crew of Sereinity travels the fringes of the ‘verse, “salvaging” and selling whatever they can.

Until recently, Sereinity was able to pass under the radar of the watchful Harmony Alliance. Now, though, a certain new passenger will make that impossible.

"Hello, hello, hello, this is Thorny Bends coming at you live on Radio Free Canterlot, and from where I'm sitting, folks, the Land of the Eternal Moon is looking lovely. Well, except for that nasty smog cloud rolling toward us from the coast, but hey, that's the price of progress. Still, if you're heading outside you might want to think about an Easy Breezy-brand respirator, guaranteed to make the air taste like new. Buy yours from all major retailers today!

"As I'm sure you all know, it's been almost a thousand years since the founding of our great civilization. And as the big day approaches, I sure hope the High Castle set their clocks right. I'd hate to find out it was really last Thursday. Ha! But seriously, folks. I've been doing a fair bit of thinking about our fair Canterlot, and I've realized it isn't just somewhere we all live. It's what we build together into something greater as we all reach for the moon. A symbol for a way of life and a state of mind. So, in honor of the thousand years, I'm taking an eye in the sky peek into the lives of the ponies on the streets, and a few in the penthouses too. I don't often do real news on this show, but these are some genuine equine interest stories, folks. In their own small, unique way, these ponies are as vital to the city as the princess of the night herself. So settle down, get comfortable, and don't touch that dial.

"You won't want to miss this, I guarantee."

The Frostmane Territories is nothing like Equestria, and nothing seems to work the same way- it's wild, the seasons run on their own schedule, and the weather has a mind of it's own. Now an entire village has gone silent, and one pilot is tasked to get a doctor there to head off a looming disaster.

The terrain is fearsome, time is running out, and events past and present will challenge him when he has to make life-or-death decisions that will affect the lives of Ponies near and far. What will he do when the line between right and wrong is blurred?

Are there some mistakes you can never recover from?
