A Starfinder Society Scenario designed for levels 3–6. In order to retrieve valuable resources necessary to repair the Wayfinders' flagship, the PCs follow-up on another team's investigative mission to a long-abandoned Starfinder Society lodge on a world in the Vast. Finding the lodge submerged and already partially flooded, the PCs quickly realize they are far from alone in the depths of the distant world's ocean. Content in Sanctuary of Drowned Delight also contributes to the ongoing goals of the Wayfinders faction.
