An Add-on Module by Necrotic Gnome

Content Provider: Necrotic Gnome Author: Necrotic Gnome Purchase Here Foundry Versions 11+ (Verified 13) Last Updated 1 month, 3 weeks ago

A bubbling stream cascades into a hole in the earth, leading to a series of underground watercourses and scintillating grottoes. Adventurers who delve within may discover odd mosses and fungi, a ruined temple complex, and the lair of a crystal-eating dream dragon.

A classic expedition into the Mythic Underworld for characters of 1st to 2nd level.

The Incandescent Grottoes can be linked with The Hole in the Oak to form a large, 3 level dungeon with over 115 keyed encounter areas!
 
The Incandescent Grottoes was awarded the coveted "The Best" rating by Bryce Lynch of tenfootpole.org!
