PROMPT Let's Build a World - Together!

Inspired somewhat by Moon's "Let's Collaborate!" thread (hard to believe it was posted a year and a half ago -- where does the time go?) and the discourse surrounding the Open World roleplay idea that never really got off the ground.

I am still of the mind that it would be interesting and fun to get ZEJ's brains together to create a world, piece by piece. It's a cool experiment that holds a lot of promise, and in general I feel that a patchwork world is a neat idea, where everyone pitches something and people build off of each other's ideas. So, to that end, I want to make it a bit interesting. We start with a single sentence, and everyone builds off of that sentence with an additional sentence. Bit by bit, we uncover wisdom about this world, its cultures, its wildlife, etc.
