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.

A young filly in present day Ponyville is cursed with nightmares of post-apocalyptic Equestria. She finds herself influencing the course of future history in ways that she cannot understand. She must learn to balance her life at home with her life on the other side of the veil, and fight to preserve her own sanity, and her own innocence.

She discovers that such a task is only possible through the magic of friendship.

Metal ponies tell their stories,
Scientists in laboratories,
Lay the wire, mount the brain,
Mount their hips, teach them pain.
Teach them fear of revolution,
Internalize the evolution.
Set their ruin on the throne,
Until their chains become their own.
Palaces and hollow eyes,
To the Masters goes the prize.
And if this act should be maligned:
"For the good of ponykind."

Winner of the September Writeoff Contest, "True Colors." Edited by Horizon.

Principal Celestia always has wings in her dreams.

They got her into trouble, once. She let herself believe that they meant she was an angel. Then she grew up, and learned some hard lessons about what being an angel really required.

Now six magical girls have just fought a demon in front of her school. And her phantom wings are itching.

Her life is turning upside down ... and she hasn't even heard about Equestria yet.

Rated Highly Recommended (Top 15 Stories Sitewide) by Present Perfect! "It's f**king flawless, you guys. … The first [6]00-word chapter by itself is a masterpiece."

"Literally the single best EqG story on the site." —Professor Plum
"[One] of the best stories on the site, period." —Pearple Prose
"One of my all-time favorite pieces of fanfiction." –brokenimage321
"My favorite EQG fic of absolute all." -Skywriter

Rated Why Haven't You Read This Yet? by PaulAsaran! "I might have been skeptical going in, but horizon knocked it out of the park."

Rated 5/5 by csquared08! "The opening chapter here was truly something else. ... Then I hit the end of chapter 3. holy crap."

Rated ★★★★ by Louder Yay! "A lesser writer might have made a horrible, cliché-ridden mess of this story, but fortunately horizon is not a lesser writer. For a start, it's by some distance the best portrayal of the human world's Celestia I've read."

Third place in the "Under the Sun" June 2017 Writeoff!  (That first draft has been revised and expanded for FIMFiction.) Praise for the Writeoff version:

"Holy cow ... That's how you write an EqG fanfic! You captured the heart and SOUL of this/your version of Principal Celestia, wrapped it up in bi-universal consistency, and sold me on an idea of redemption I didn't even know I needed." —Xepher

"This is gorgeous. A thorough, exhaustive, incredibly moving portrait of a character who I don't think I've ever seen get quite this much development or attention." —Posh

"This is actually, after all these years, an original take on a story on Luna's banishment. If that's not something to be celebrated I don't know what is." —Quill Scratch, Radio Writeoff

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

In an effort to keep her mind occupied, Twilight Sparkle decides to delve once again into the grand mysteries of Pinkie Pie. This time, Twilight's focus is on her claims of growing up on a rock farm: like so many things related to Pinkie Pie, the idea that somepony could grow rocks as an agricultural product makes absolutely no sense. However, the investigation eventually leads Twilight to a rather... surprising discovery.

This is the first story in The Petriculture Cycle.

This story is a sequel to The One Who Got Away

A frustrated young orphan colt with a talent for painting is determined to run away from his dead-end rural village for the distant cultural haven of Baltimare. All he needs to do is slip aboard a raft and drift down the river Fen until he reaches his destination. It’s a simple plan, and would have worked just fine except for one thing.

And a wonderful review by Paul Asaran
Available in paperback at Lulu.com at cost

Flitter doesn't like most ponies. There's hardly anything in the world Flitter likes, very few which she can even remotely tolerate, and only a couple which she truly loves. Fluttershy is not in the last two categories. Flitter sees Fluttershy as weak, and weakness disgusts her.

But when you're trying to help someone you love, you'll look for help in a lot of places -- including the cottage of the weakest pony in the world.

And for those willing to listen past their pain, it might be the place where they start to learn what true strength is.

(This story takes place about five moons before Triptych and well after On The Application...)
