Been a while since we had a 'Let's build a world!' thread.

Everyone posts a fact about the world, or it's inhabitants, or culture, or whatever, and doesn't contradict a previous poster unless it's something stupid like 'everyone is sergals and furry priestdoms rule the world'.

The majority of the action takes place on islands floating in the sky, ranging from a few metres across to the size of Australia. The lands below are shrouded in mist and, while inhabitable, are insanely dangerous because of things lurking in the shroud - spirits that hate life. They're typically dormant, though the wildlife is not. The islands can be steered, but it takes a lot of time and energy.
