Proximity
The Proximity of a location with icon measures how close it is to the capital with icon of its Owner, and it determines how much control with icon Locations can have.
Proximity starts at 100% in the Capital of every Country, and jumps to nearby Locations, giving them Proximity. Some Proximity is lost with every subsequent jump, depending on the terrain and the infrastructure present in the Location. The Proximity that is lost in jumping from one Location to the next is called Proximity Cost.
The Proximity cost between Locations varies greatly with topography with icon and vegetation with icon. On land, it can be reduced by building roads with icon, increasing development with icon, and the land societal value with icon. On sea, it can be reduced by harbor capacity with icon, maritime presence with icon and the naval Societal Value.
