Humans are great explorers, and the Solomani are the greatest of them all. Ever since the days of the Interstellar Wars the people of Terra have felt the call of the great Rimward Frontier, and they have answered. This outward urge has taken Solomani explorers right to the edge of the spiral arm and beyond. The Lubbock and Xuanzang Enclaves are little havens of civilization out in the big black. Just keeping these forward exploration bases supported is adventure enough for many, but beyond them lies the unknown; the mysterious Rammak, the civilization to reach and investigate the curious region known as the Spinner, and of course the long voyage out to Point Cetus the most distant installation yet built by the Solomani people. There are many challenges on the Rimward Frontier. Rival Aslan and Hiver exploration missions, strange alien races, and the mysterious Hordes advancing out of the Flous Nebula. The greatest danger may come from other humans, descended from Rule of Man and early Terran colony missions.
