Unlike other Dungeon Crawl Classics, this volume does not present a completed adventure. Instead, it presents a set of DM tools that will make your job easier. This book of dungeon geomorphs gives you everything you need to map out exciting underground adventures. The geomorphs are modular map segments designed to be combined in a variety of ways. There are 124 map segments, encompassing mazes, dungeons, underdeep caverns, monstrous lairs, castles, ruins, halls, and many other intriguing places to explore. Together they combine to make thousands of possible maps!
