Cave of Years

publisher blurb The Cave of Years is a large, multi-level, cave complex, with a single entrance and many ways out. Each exit is a pathway to another time and place, potentially leading Adventurers from the Dawn of History to the Age of Space. Inside the cave are people and technologies from across all of history, presenting a variety of environments and challenges. The cave is highly non-linear, with a large number of pathways and options. There are nine adventuring areas on five elevations, a river, chasm, underground lakes, and complex terrain. The Cave of Years is written using Spellbook Game’s Portal to Adventure rules, but can be used as-is with original D&D and similar rule sets. It is suitable for Adventurers of L3 to L6.
