This world was split into six different districts, where each one would represent a different era in time. The first district was the futuristic era where people had hover cars and robots to do most of their work for them with their huge mana. The second district was the science era where people were just starting to develop a new world where they would discover the existence of magic from science. The third district was the technology era, where people started to develop smartphones and laptops. The fourth district was the industrial revolution era where people just started to develop new technologies. The fifth district was the Victorian era where people were ruled by the monarchy. Lastly, the sixth district was the time where people just started to live in civilizations with other people.
