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.

Spike is her number-one assistant and that will never change. Even in her becoming a greater princess he has not failed in that role.

Isn't it odd how a dragon can compensate for a castle?

Twilight discovers his secret... and must save him from it.

All are condemned either to a passion or an obsession.

Twilight Sparkle is pregnant - and nopony is more surprised than she is. Confronted with the overwhelming responsibility of motherhood, the young mare has to decide whether she is truly up to the task of being a single parent. For a pony who has proven her dedication, intelligence, and strength of character countless times, armed with the bonds of friendship and love, it shouldn't be a difficult choice.

But, as with everything Twilight has done in her life, the circumstances and decisions she must manage are anything but simple.

Fluttershy has always believed that she doesn't have a soulmate, as their cutie mark never appeared on her right hoof. But when she encounters the villain she and her friends are facing, she might be proven wrong.

Soulmate AU

Diamond Tiara knows all about work delegation: if you want something done, have other ponies do it for you. In the name of that goal, Silver Spoon studies for both and Diamond copies her friend's efforts. It works every time. Except that Cheerilee just forced Diamond to switch desks. And with finals a week away and no personal knowledge for most of the subjects, the only ponies she can now hope to copy from are Snips and Snails. Something which may get her sent all the way back to preschool. And there's no way Diamond is going to lower herself to doing her own work.

Which means the colts are going to be learning on her behalf.

No matter what she has to do to make that happen.

It's for the best cause ever, after all.

Twilight's just received her official government escort license, which allows her to legally take on passengers during a teleport. Unfortunately, the fee was hideously expensive -- enough to completely wipe out all her spare bits. And there's a major purchase coming up which she refuses to put off. So what better way to raise the money than by giving her freshly-approved skill a workout? After all, it's winter, it's cold, ponies will get home all the faster, and since Twilight knows what 'escort' means, so will everypony else.

It's probably best not to bet on that last part.

Deciding to check it out, she discovers a strange weapon of unknown origin that seems to mesmerize its targets. There are... drawbacks to this weapon, however, and its discovery soon leads Coin down a chain of events that will change her morals, lifestyle, and even her very soul... provided that she manages to survive. Will the friends she makes be enough to convince her that her slaving ways are immoral? Or will they just reinforce the belief that that is one of the best ways to survive After the End?

Waking up with a hole in the head might seem like a bad way to start your life, but what if you deserved it?

"Every pony like me should be shot in the head at least once."

When he discovers the entire wasteland hates him, the amnesiac Ripple, once Two-Kick Rip the raider warlord, sees his wounds in a very new light. On a path that's half vengeance and half bid to redeem himself, he must rid the wasteland of his old gang and another, much more sinister foe.
