A classic expedition into the Mythic Underworld: a bubbling stream cascades into a hole in the earth, leading to a series of pools, underground watercourses, and scintillating grottoes. Adventurers who delve within may discover a profusion of odd mosses and fungi, an ancient tomb complex, the lairs of weird, subterranean monsters, and the hide-out of an exiled illusionist. The Incandescent Grottoes is a companion adventure to Gavin's previous scenario, The Hole in the Oak. The two adventures can be played independently of each other or can be connected to form a larger dungeon. Designed for characters of level 1-2. Written by Gavin Norman and illustrated by Nate Treme.
