A group of snaketongue cultists has occupied an abandoned, partially sunken temple near a swamp. They grow impatient waiting for their yuan-ti master to join them, unaware that he has been slain by a rival faction of yuan-ti. Frustrated, the cult strikes against nearby villages in the hope of drawing the favor of Zehir. Investigating rumors of a serpent cult harassing a nearby town, the PCs have explored the swamp and discovered the overgrown temple. Its once-ornate stone door now hangs off its hinges, providing a narrow space for one character at a time to squeeze through. Pgs. 42-47
