Publisher blurb: A Tweak & Toss adventure seed where the PCs are asked to delve deep underground to prove a sage's theory on the origin of life. User summary: This "generic" adventure is compatible with any "old school" fantasy game system. The adventure does not present statistics but only narrative encounters and maps. Prior to use, the game master would need to "tweak" the module by deriving statistics, etc., for whatever rules system is being used.
