If you want to pick up a lot of interesting background info on the world, story, and characters that hasn't necessarily been shown yet, the Kickstarter is well worth reading (and pretty awesome anyway).
There's a link right at the bottom of the page.
@Stormcrow: Sometimes background only confuses things. E.g.: outside of the khert there's no pymary, living things die and inanimate ones discorporate. Khert does not stretch far over water. This means no nautical pymary - no conjuring up favorable winds, no plod-rowed galleys, no pymaric powerboats. It also means strictly coastal navigation, which in turn means exclusively fore-and-aft rigs. Then what the heck do the square-riggers do in Ch.6, Pg.15, top frame?! There are also what appears to be powerboats with searchlights in Ch.6, Pg.15 top frame and Ch.6, Pg.16-17 middle frames. I am yet to find an explanation.
