I decided to call this one "final".
The concept of the world, in case you did not read the WIP thread and its explanations and schematics, is that the world had a flourishing civilization in the past, and a vast underworld that lay hidden beneath the surface. In a great cataclysm the underworld partially collapsed, draining the oceans in the process. Between the earthquakes, the shift in climate and the resulting famines, and the wars that immediately started as survivors from surface and underworld fought over resources and safe locations, the civilization collapsed and the world became a new savage wilderness.
I'll definitely continue to develop this world in the future.
