Middle region's 10th floor was a wide expanse of land that solely housed a large kobold tribe. The leader of the tribe was a kobold lord with a higher bloodline purity than an average kobold and is usually the highest in the tribe. If any other kobold with a high bloodline purity than average kobolds but less than the chief's appears, it would serve directly under the chief as a guard and would only be beneath it in terms of authority. Such a simple political structure might seem to have a lot of loopholes and would result in terrible governance and whatnot, but it didn't matter to these simplistic creatures. All they needed was a leader and be it a dictator, a democrat or a republican, they didn't care.
