Civil Service

Civil Service is a terrifying, mandatory draft enforced by the Department of Civil Service (DCS) that secretly supplies the Planners with the human lives required to keep the sky cities afloat. While topside Citizens are indoctrinated to believe that being "Selected" is a noble honor to maintain the city's infrastructure, the reality is that victims are either enslaved to power magical forcefields or murdered in front of darkprime saplings to generate new metalwood.
