Three dungeons in one! The party is given a "dimension shifting device" and sets out to explore a 15-area cave, simultaneously occupied by the DEMON CORSAIRS, the remnants of an ASTEROID MINING OPERATION, and the MONASTERY OF TRANQUILITY & TRANSCENDENCE! The three dungeons are presented in three columns, so when the characters shift from one dimension into another, it's easy to find the corresponding area description. For use with old-school or OSR RPG systems. Recommended for character levels 3-4. Published by Eldritch Fields.
