Starting to get a bit run down, Earth is home to the vast majority of Humanity. A mixture of dense city and arid wasteland, it relies on nearby planets to produce goods the people need to survive, terraforming and moving most production off-planet is slowly returning earth’s o-zone layer and pulling it back from destruction.
LUNA (Moon): Due to trouble terraforming, the moon is almost entirely covered one large space-station style city. Most companies keep a headquarters here as it has become the Corporate centre for earth, mainly due to the lack of Earth-Law (The Moon is officially corporation-ruled). As a result, espionage is high here, and although reported as lower, violent crime (especially murder) is believed to be significantly higher.
