It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.

Sequel: Project Sunflower: Harmony

Set in the far future after Celestia and Luna mysteriously vanished and the sun and moon froze in the sky, Antipodes is the story of two ponies thrust out into the harsh new world on an adventure to uncover what happened to the world so long ago.

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

A refined mare fresh out of high school and a dropout following her dreams find themselves forced to spend a lot of time together.

With the help of a meddling psychology tutor and their new classmates, can they find what they've been looking for?

Fan Stuff!

A 'Know your Star' story; only with your favourite ponies getting unneeded hassle and lies told about them. Won't this be fun? Probably not... But hey, everything can't be seriousness all the time, so let's take a load off and just pester some ponies, and Spike for good measure.

The never ending adventures of Know Your Mare march on and on and on.
