The gods of this world created a Dyson sphere which is 22.5 times the surface space of earth. It is divided up into 9 sections, or "realms", which are self-contained worlds that humans live in. These world's are part of a realm gate system that connects then to each other. They each contain one gate which leads to a large way station, in which connections to the other gates can be made. This network has allowed people to travel from world to world, giving rise to intermundane commerce.
The powerful organization responsible for administering and controlling this network exists in all the realms and regulates the commerce between them, giving them much power and influence with realm governments. However, they have sole access to special tech that allows them to bypass this network entirely. Using specialized rings, they can open a miniaturized gate that transports them directly to the realm of their choice. This gives them instant access to a world without having to make the travel to the main gate common people must use. While they can travel in-between worlds, instant travel within a world is not possible.They must still travel from place to place using traditional modes of transportation. This does not make sense.
Why would interplanetary travel from world to world be possible, but instant transfer within a world be prevented?
