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.

This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.

Starlight Glimmer's attempts to stop the Rainboom pulled Twilight Sparkle into many possible timestreams.

In one, Rarity and Rainbow Dash survived Nightmare Moon's victory over the forces of light, eventually attaining positions of prominence and comfort in the Nightmare's service. But when the unexpected visit of an Alicorn and Dragon sheds light on a growing conspiracy against the wicked mistress of the night, Rarity and Rainbow Dash may yet be inspired to risk what they have gained to join the fight for a better world.

Yet darkness lingers even in the hearts of some who would oppose the Nightmare, and not all agree on what a better world would look like...

Lyra and Bon Bon love each other, but they have a ... somewhat unusual relationship. One of them is a secret agent. One of them is a changeling.

And the third one is a perfectly normal pony, about to have her life turned upside down.

This may result in some questionable relationship decisions.

It turns out that the magical land of Equestria is not a flat plane covered by a bowl of stars after all. This is big news to Queen Chrysalis. If the moon is actually a place, then she can travel there, claim its magical energies, and finally get revenge on Celestia, Twilight Sparkle, and everypony else.

Of course, there are problems. One problem is that everypony else is also rushing to get into space. Another problem is that Chrysalis really has no idea how to do it. Fortunately a certain earth pony with a taste for cherries is willing to help... provided she gets to fly the ship, and provided Chrysalis keeps the space program honest and open and legal.

Together, Chrysalis, Cherry Berry, and a horde of brave-but-dumb changelings will make world history... or, more likely, they'll make a lot of really big explosions.

Filthy Rich has a problem. His daughter, Diamond Tiara, keeps breaking her promises to treat her classmates with more respect. In fact, she doesn't even seem to really understand what a promise is. Since punishing her does not seem to have much effect, Mr Rich is forced to consider a more creative parenting method. But how can he make such a spoiled, materialistic little filly as Diamond Tiara see the value of a promise?

With money, of course!

Now has a dramatic reading on Youtube! Kudos to DRWolf.

Princess Celestia is the paragon of Harmony. She is kind to her subjects and generous to those in need. She is loyal to her ideals and never compromised. She has a good, if mostly unknown, sense of humor. Above all else, she is always honest. Right?

Twilight Sparkle trusts Princess Celestia implicitly and in all things. The Princess has never steered her wrong, not once. When Twilight thought that her concerns for Nightmare Moon were being ignored, Celestia had her back, even if she was withholding information.

Wait a minute.

Shortly before Celestia leaves for Canterlot with the redeemed Luna, Twilight has a conversation with her mentor that will change her perspective on the Princess forever. She will receive something new, beautiful, and damning all the same.

Cynicism.

This story is a sequel to Past Sins

Hearth's Warming is a time for friends and family to come together, celebrate harmony, and welcome the new year. Nyx is looking forward to just this as she rides the train to Canterlot with Spike and Twilight. She's going to meet her extended family for the first time and wants nothing more than to make a good impression. Yet, the sheen of the holidays can't hide the trouble caused by meddling grandparents, relentless reporters, and a paranoid uncle.

There are 100 billion stars in the Milky Way, and humanity is determined to explore every one. We send probes, probes with the blueprints to reproduce human explorers upon arrival. Uninhabited worlds the galaxy over can be colonized and populated, until after many years they too can join the vast throng of interstellar civilization. But if a probe is very, very lucky, it will land on a populated world instead. Equestria is one such world.

Even so, it's far from perfect for colonization, not with an environment lethal to human life. But each probe is resourceful and armed with the greatest machine intelligence mankind has devised. If placing a human mind into a newly manufactured human body won't work, it will just have to get a little more creative.

Fantastic prereading help from: Chyre, Danger Noodle, Doctor Disco, and Doggyshakespeare (who also did the Esperanto translation). Thank you all for helping to make this story more readable and more consistent for everyone.

The nation of Equestria has been exploring their little slice of the universe for some time now. From launching probes into deep space, to landing ponies on the moon. Sending things beyond the grasp of their planet has become almost routine. However, with every mission into space, there comes a time when the voyage must end. What happens when Equestria experiences the end of a voyage that they didn't begin?
