Southern Control Zone
The Southern Control Zone is a zone of economic and military control maintained by the joint military of the Union Australis. The zone encompasses all waters south of lands that exist outside of the line of permanent sea ice that surrounds the south pole of Micras. The zone is patrolled by ships from both the Caradian Black Armada and Ciric navy that are tasked with preventing the passage of ships from nations that do not reside in antarctic waters through the zone. In accordance with this, no foreign private ships are allowed passage without a toll, and military ships of foreign nations are denied passage entirely. Because of their recognised claims within the southern waters, ships flying the flag of Sanama, Mercury, or the Imperial Trade Union are both allowed free passage through the zone and protected from piracy by union ships.
