From publisher blurb: Once, the Orion Arm was humanity's plaything, the Earth Alliance expanding by leaps across interstellar space. But as happens with all our species creates, it was destroyed through greed and lust for power and spite. A thousand years on, space is still dark, but light sometimes flickers for a while in a little corner here or there. The dream of the Alliance dies hard, and over and over one world or another has tried to recreate a fraction of its glory, only to fail. Sapphal is a former prison planet left to its own fate for centuries after the Earth Alliance fell. Now home to a world-spanning low tech empire, it's become an important trading destination and a lure for freebooters and other unsavory adventurers. Pack your laser rifle, put on your brown leather hat, and make your fortune if you can on a world where high-tech luxuries are few and far between. It can be used as part of the larger Three Clusters setting or as a "drop-in" for a GM who needs a detailed destination to use in another campaign.
