Systema Tartarobasis

This science-fantasy adventure module is set among the ruins of technologically advanced cities beneath the surface of an unfamiliar world. Characters explore these subterranean environments, encounter new creatures and important NPCs, and uncover the region’s cultural and technological remnants. The module includes maps, an illustration booklet, and appendices with monsters, characters, and setting details, with rules for Castles & Crusades and guidance for adapting it to other fantasy or planetary-romance systems.
