Sky Cities
Sky cities were invented by humankind when the corrupt plants took over Earth, each region has its own sky cities. These cities float in the air powered by complicated machinery. Comparable to that of a cyberpunk fantasy, these cities mostly consist of high-rise buildings and small alleyways to traverse the cities. Here in these cities, a lot of humans and 'bucks reside even after the plant life is gone and the ground is once again safe. These cities by the time of the Kaeraa war ending were roughly a century old but some were so used to calling them home they wanted to continue their life in these cities.
