The Sundered Ocean

From publisher blurb:

It’s a race against time as the PCs accept a contract from a doctor to find her stepsister, who is carrying a deadly but still-dormant disease, and administer a cure before a pandemic results. Tracing the target to the ocean world of Yemoja, the heroes quickly find themselves at the intersection of cultural conflict and human depravity. Meanwhile, a gigantic storm threatens to write the final chapter of the world’s history…and the heroes’ lives.

The Sundered Ocean is an adventure designed for use with Cepheus Engine (CE) and the Original Science Fiction Roleplaying Game (OSFRPG), although it can be ported to other RPG systems or even other genres with minimal work.
