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.

There is now a follow-up to this story: Sunflower - Side Projects
Sequel: Project Sunflower: Harmony

We are writing the year 2100; the world has recovered from the third world war and is finally on the way to a better future; humanity has developed entire new technologies which make it possible to stop the environmental pollution and make life brighter and easier for everyone. 7 years ago a young scientist made a break-through in transportation: he invented teleportation.
Today the machine is finally ready to be used by a human, ex-astronaut Jan Schneider is the first tester; everything goes as planned, but on one sudden day, the machine fails and sends him to a different planet, to a different place, well known as Equestria. But was it really the machine which failed? Or has somebody an eye on him?

Recently rewritten. Contains occasional adult humor and violence.

Ambushed. Defeated. Broken. Banished from his world, he expected his story to end, his revenge unfulfilled. Instead, he found himself in a new world - a world of peace, tranquility, and harmony.

May God help them.

Thanks for everything guys. I never expected this thing to get so popular. I need to rework the second chapter, but it looks like there's going to be a blue moon every Friday for a while yet. Thanks again for your support and please keep reading and reviewing!

EDIT2: I've updated the character list again, a little preview of the second story arc...

EDIT 3: Just doing a quick character update to account for changes made to the next Arc...

One changeling is sent far from the swarm, hurt and stranded; forced to listen and unable to act as terrible events take place that will change her future forever.

When everything she knows is lost, she'll have to find her own path. She will confront the demons of her past, the harsh realities of the present, and the uncertainty of her future.

Season 2 based story.

Follows the prequel "In the Shadow of a Special Day", which is not required to understand the story.

Rated T for mild to moderate violence and minor obscenities. Dark, but not a shock fic.

Cover art is "Changeling Angst" by the-ghostcat-pir8nin at Deviantart.
