Kuo Toa Cave
A subterranean cave on Prewth Island that was inhabited by a collection of human cultists and Kuo Toa. It is below one of the major rivers that flow from Mount Vraalt, on the western side of the island.
Session #9 (3rd Era) – The crew of the Sea Word found some Cottonwood trees on an island in the middle of the river and while there they saw a secret door that went through the earth to an underground cave where they found more of the trees. While they were here they had to fend off an attack by the cultists and the Kuo Toa.
