S'arys is the core of a former hot gas giant orbiting close to a class A star. Some ancient astronomical catastrophe stripped away the old atmosphere, most likely in a series of close encounters with a long destroyed companion world. More recent impacts have punched through the surface of the denuded planetary core and exposed a unique geology of microstrata originally formed under conditions of extreme pressure. Laminar flows and exotic chemistry concentrated valuable metals, rare earths and elements from the heavy end of the periodic table. Human settlement is now built around the refineries and mines that burrow underground in deep craters both to follow the seams and to escape the surface vacuuum and the dangerous heat and light. Refinery 23, seen here, is a typical outpost. The citizens and investors in S'arys are hardy and brutal but they are also incredibly wealthy.
