This is a random idea I had. Basically a totally freestyle RPG. It's scifi style, and most major races are descended from humans that modified themselves to suit their environment (originally Sadie's idea, but I've made it my own). I have a few species ideas, but feel free to create your own. Then, just write. You can have your characters interact with others, but you don't need to. You can have entirely self-contained plotlines, or you can make them interact with other plotlines (just don't change them too drastically without permission).
A few things:
The Sol system no longer exists. It was invaded by the Plague (who I will explain later) and humans, rather than fall to the Plague or be destroyed in the war, used a superweapon to destroy the sun and vaporize the entire system. They fled to the Centauri star system, where they formed several governments, eventually uniting to become the United Associated Alpha Centaurian and Proxima Centaurian Orbital Colonies.
The Plague are microorganisms that can use their own biomass to transform and control other creatures. Detailed in their own personal thread.

That's pretty much it. Hopefully, everyone will have fun with this.
