Hierarchical City

A Hierarchical City (階層都市) is a term used to describe cities that were built after the Great Dark War by the World Void Information Controlling Organization. There are 23 hierarchical cities known thus far.

Information
After the Great Dark War, which left a large amount of hazardous magic element that covered the world, a lot of humans and animals became tainted with the magic element and died off. Humans were forced to move to high altitude, mountainous areas where concentration of magic element is lesser. Hierarchical Cities exist around the world in various regions, and each one is assigned a number. The highest placed Hierarchical City is the first, the lower it is, the higher the number of the city. In each hierarchy are many cities, towns, villages. The upper level contains the Controlling Organization branch office, while the higher layers are reserved for the wealthy, Controlling Organization personnel, and collaborators. The poor, refugees, and other indigenous races live in the lower layers.

Weather in the cities is maintained by the environment maintenance device, and they are also surrounded by a special barrier. Its properties are unknown, but according to Hakumen, it’s similar to the Ishana’s barrier.

People travel between cities by aircrafts, which are monitored by the Controlling Organization. Some exceptions are Ikaruga Federation cities, as they’re so close to each other that people can travel between them by trains safely.

Each of the Hierarchical Cities have a Kiln deep within.
