This planet was originally divided by a vast ocean. The continent on the east coast of the ocean is full of rich magical elements. There are magicians and quaint big cities on that continent. People's lives are full of magic. Although most people can only use extremely low-level magic, they also share the same set of most basic magic circuits. On the continent on the other side of the ocean, due to the lack of magic elements, there are no wizards at all. Therefore, the mechanical civilization is highly developed and there is a profession of mechanics.
Originally, the two continents hated each other. People on the east coast looked down on people on the west coast who could not use magic. People on the west coast despised people on the east coast for being uneducated. Originally, this kind of life should have continued, but one day the two continents were connected due to a plate collision (West Coast people's language) and God's will (East Coast people's language), and they had to start a life of coexistence of magic and machinery.
