The Exo-Guardians faction once maintained an impressive fortress known as Sangoro's Bulwark. Years ago, mysterious forces assaulted the bulwark, and the location was thought forever lost—until now. The Starfinder Society selects the PCs to launch an initial foray back to the area around Sangoro's Bulwark, in hopes of retrieving a cache of deadly weapons the Exo-Guardians had guarded before the fortress fell. Can the PCs discover the lost weapons before they fall into the wrong hands?
Sangoro's Lament is the first of two adventures in the Stumbling Society series. This adventure is followed by Starfinder Society Scenario #2-08: The Stumbling Society, Part 2: Sangoro's Gifts. These two scenarios are intended to be played in order.
