Twilight Sparkle discovers the human science of advertising. Being Twilight, she can't help but propose a new ad campaign to Princesses Celestia and Luna promoting the Conversion Bureaus. And being Twilight, neither can she resist pulling the mane six into this little project, and then taking things a bit too far.
As usual, Princess Celestia takes all of this in stride, knowing she can cope with anything Twilight dreams up. Or can she?

The pocket universe of Equestria expands in the North Pacific of a dying future earth. Celestia offers escape to a better life - but survival has a price. 27 Ounces follows the dramatic transformations that arise from one single container of Ponification Serum.

At the heart of every Conversion Bureau is 'potion', the nanotechnomagical serum that converts a human into an Equestrian. But before the Bureaus could exist, the serum had to be created first. This is the story of how the first successful conversion serum was developed, and of the humans and ponies that made it possible.

It's not real, it can't be real. Ponies are just cartoons and some fanfics on the internet. The wings, the hooves... I'm just having a bad dream!
I wish that were true. But pain, friends, and a strange drink are telling me this is all too real. I'm a pony now and I think the world is falling apart.
People, the end is nigh, the world has decided to go out with a bang, and it's taking us along for the ride.

*Loosely based on "The Conversion Bureau" universe.*
*Note about the art. Chatoyance was very kind to create some fan art. Just as a little note though "John" has brown hair not bond. Just a little tidbit to keep in mind while reading. Thanks so much again Chatoyance!*

This collection of stories is set in an alternative Conversion Bureau timeline where Mankind reigns triumphant, having destroyed Equestria and sent it back into the sea. The only remnants are Celestia's severed head and the now-docile earth ponies that are made from her blood.

As mankind claws itself back from the brink of extinction, it must build a new society and move forwards into the future, with a changed destiny shared now by two sentient life-forms. In this collection, stories will be spun about sacrifice, loss, and nobility of spirit, of two hands and four hooves.

Hegira (n.) - "A flight, or journey, to a more desirable place."

Life is a series of choices. When two worlds collide, choice becomes more difficult, and nuanced. A dying planet has a peculiar way of reshuffling people's priorities.

For a long time, humanity has only had three options: Ignore the inevitable, risk the unthinkable, or become the unimaginable.

All that is about to change.

Everyone knows the Ponies of Equestria fairly well... But here, there be Gryphons.

Book One of the Hegira Trilogy - This story only takes MLP G4 Seasons 1 - 3 as cannon, and ignores 4 and onwards.
