Apolis is a fractured land. A disaster of cosmic proportions descended upon this world in the past and left it broken and destroyed. This disaster scattered the planet across different dimensions (the areas affected by these dimensions are called Zones), making the surface of the world immensely variable in nature and immensely dangerous.
That doesn’t mean it’s uninhabitable, however.
Through the use of Vehicles and magic, people have managed to stabilise local space and create inhabitable Zones, called Homesteads.
However, any settlement needs a method to transport supplies and people, as well as people to operate these methods, and in Apolis, those people are called Operators.
