The potion used to transform people into ponies has gone through many, many interations. When one of the older potions is used, results aren't quite what was expected.

EDIT: I used a piece of fanart which I thought was wonderful as the cover image :3

In the many years after the Conversion Bureaus' shutdown, Twilight Sparkle is tasked by the Princesses with finding the last living human on Earth, Isaac Hamilton, and learning the story of his past. What she hears is a tale of loss, tragedy, joy, and the discovery of one's place in the world. But how much longer would that place last with what Twilight has to tell him?

This is a direct side-story spinoff to "A Twist in the Tail".

Edge used to be human. She used to be a man. Then one day, she was foolish enough to break into a Conversion Bureau to steal some Potion. Believing it all to be a plot to 'scoop out the brains of humans', he downs it. She wakes up as a pegasus pony with an audience with the princesses...

For her crimes, she is sentenced to community service.

This won't end well ;)

Author: Pinkie Pie, shut up! No you can't name- You already did. Son of a...
Pinkie Pie: So author, you're always writing stories about me! How about I write a story about YOU!?
Author: That is a horrible... horrible... HORRIBLE ide-
Pinkie: Spectacularific! Let's do it!

A hack author (from "Extremely Terrible and Horrifying Stories" and "Mystery Pinkie Pie Theater 3000") is attempting to write his next magnum opus. Then Pinkie Pie happens.
Not the most original idea in existence, but hey, this is my take on how it would play out.

Fan-fiction that will show you the harmony found in our hearts!

The fate of Equestria will be decided not by the madness of battle, but by the harmony between each other...

Twilight, a student from Canterlot, and her dragon companion, Spike, find themselves caught in an mission to find the elements of harmony to stop the the crazed mare, Nightmare Moon. Equestria is not a land of love and tolerance, but a land that has been ravaged by racial conflict, sudden earthquakes, dangerous chimeras, and the shadows within a pony's heart. Only with friends can Twilight find the strength to stop Nightmare Moon.

To save Equestria, Twilight will have to prevail against power-hungry ponies and those who would wish to stop the gathering of the elements of harmony. Honesty, Laughter, Kindness, Generosity, Loyalty, and Magic. Are these strong enough to fight the wicked?

Take strength from friendship.
Take pride in love. Take
Everything that you believe in-
and turn it all to power.

A tragic accident robs Jay and many of his friends of their parents. Seeing no alternative aside from a life on the streets and poverty, they enroll in the Conversion Bureau program to emmigrate to Equestria. When Jay finds out that his close childhood friend and crush, Chloe, is going as well, he takes it upon himself to win her affection before the end of their ten day stay.

An ancient manuscript written in Middle English, the only surviving artifact from long lost Earth, may hold the true reason for the emergence of Equestria, the very existence of the Conversion Bureaus, and the deepest secret of Princess Celestia herself.

This story is a continuation and expansion of 'The Conversion Bureau: Letters From Home', but it is not necessary to have read that story to enjoy and follow this one.

A minor accident at Sweet Apple Acres sends Big Macintosh to Ponyville in the middle of applebuck season. At first, things seem fine. But then some of the mares begin acting a little...oddly.

Then very oddly. Turns out every other stallion skipped town for a very good reason.

When Rarity is given an order for a dress, a series of unfortunate circumstances lead her to request the aid of Twilight Sparkle. When she discovers that Twilight has been studying time spells, she asks if she can help her recover some of her time. Reluctantly, Twilight agrees, but when she is performing her spell, something breaks her concentration causing the spell to become unstable, sending them 15 years into the future. What awaits them in a world where they have been missing for so long? Will they ever get back to their own time? Only time will tell.

Seriously, check out his work. He is one of my favorite pony artists.

Apple Bloom is tired of being on her own. With time stopping for nopony and a great, bright beacon calling to her, the little earth pony makes one of the hardest decisions of her life, and embarks on one last crusade with her friends.

However, one friend is not so quick to accept the truth. Can a certain little white filly learn to cope with the thing she fears most - saying goodbye?
