From publisher blurb:
Who would have thought that an evil cult dedicated to the supremacy of the storm deity hides their scheming under the surface of a peaceful fishing village like Oyster Cove? No one who currently lives there, and who is not a member of the cult, apparently. If you're running this module as a sequel to Found by the Way #02: Path to The Gnome's Argosy, your party discovers that the helpful contact whom they seek is really the leader of the cult, and that he's plotting to usurp and kill the village elder so that he and his cabal can use Oyster Cove openly as their base of operations. If you're running this module as a stand-alone, the party can still uncover their grand ambition to paralyze merchant shipping throughout this part of your campaign world.
