Middle region's 10th floor was a wide expanse of land that solely housed a low-levelled large kobold tribe. While the monsters were classified as low levelled creatures, they were the apex predators in their location, being the only existing species on the floor.
From a simple overall view, the 10th floor only consisted of the wide expanse of uneven land, a large kobold settlement and a bunch of tunnels that lead to the other floors. Due to some certain unknown reasons, a majority of these tunnels couldn't be accessed by players while some of the ones that could be, weren't available to the kobolds. Such a contradiction couldn't be explained by anyone, mostly because very few players had actually discovered this situation.
