The underground tunnels are a masterpiece of the Dwarves, tracing back to over a thousand years ago. During the Dwarves' heyday, the Emperor of the Human Empire, Charlemagne, and the Dwarf Supreme King, Kazadni, agreed that the plains and hills on the Continent would belong to humans, while the mountains, wastelands, plateaus, and all the terrains unsuitable for human habitation would belong to the Dwarves. The relationship between humans and Dwarves was close; any human visiting the Dwarf nation would receive a warm welcome, and Dwarves visiting the Human Empire would be hosted by the local nobility.
