From publisher blurb:
Yemoja is a water world whose natives are descended from a third, and finally successful, attempt to settle the planet. Its society was disrupted long ago by a particularly-bad cyclonic storm, one that not only ravaged the landscape, but also the culture. The resulting social schism left the well-to-do citizens trapped aboard an orbital highport, while the downtrodden surface dwellers eke out a meager existence on the dangerous planetary surface.
Port of Call: Yemoja introduces Cepheus Engine and Original Science Fiction Roleplaying Game (OSFRPG) players to this danger-ridden duality of a planet. Inside is an overview of how the information would appear in the PCs’ library database, physical planetary and system information, a brief history, a look at its government, technology, and society, a quick guide to crafting characters that would hail from such a place and maps to help Referees envision the area.
Port of Call: Yemoja. The storms aren’t the only things to watch out for.
