Antarctica

Antarctica (南極, Nankyoku) is the Earth's southernmost continent, mostly covered in ice and containing the Earth's geographical South Pole.

Background
Though it has no national borders, Antarctica has been the subject of intense competition for area rights between various nations seeking to obtain its resources, even before the fall of the United Nations. The powers claiming right to Antarctica in the present include the destroyed Oceanian military nation, the Capitalist Corporations' Central Valley area in Western America, the Information Alliance's Chonos Archipelago area and the Legitimacy Kingdom's southern Great Britain area.

An Audition War
Quenser Barbotage and Heivia Winchell were sent to Antarctica in order to investigate a terrorist group who fired on a Legitimacy Kingdom aircraft.
