Currently, they teleport from surface to surface. Later, a kind of hub is planned, such as a black hole that is kept alive with energy and resources. The connections should always be direct, so a new setup must be built for each pair of connections.
All planned aspects should later be in harmony with each other in order to produce extremely large quantities of resources and deliver them to the "central company."
And yes, some small things like the attractor have been included for my own benefit, although something like that could be a "reward" for deliveries and therefore uncraftable.
