The Stars are Watching
Old Earth, the planet that mothered all of humanity. Now void of any useful natural resources contains humanity’s poorest and downtrodden. There are also those through mere sentimentality refuse to leave this dead planet.
Earth is also a hub for humanity as it is the point of origin and exact center of the human empire. While a lot of wealth passes through earth’s interplanetary ports very little remains. Fortunately escape is relatively easy and fortune can be gained off world, mostly in The Outer Sphere.
