Within the sphere of the Known World is another world, the Hollow World. There your characters will meet ancient Nithians, long disappeared from the surface of the world and thought extinct: Blacklore Elves living in a magical valley and served by automatons - devices that take care of everything, from serving their food, to trimming their grass: Azcans, terrifying, war-mongering natives whose whose taste for battle extends even into their favorite game - the losers always die - and many more. Monsters abound as well, from dinosaurs to aurochs.
