Bellerophon

Bellerophon is a world orbiting the gas giant Qin Shi Huang in the White Sun system. Bellerophon has very little local industry and has become a retreat for the rich and powerful. Giant, antigravity estates and resorts float over the oceans, populated by the rich and their servants. Less expensive resort towns dot the shores. Most of the inland areas are very dry and unpleasant.
