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!

A lone fortified Keep is the only bastion of Good desperately striving to maintain the forces of Chaos at bay. But Evil is everywhere, lurking in dark caves, fetid swamps, forlorn forests.

An Adventure for 0-Level Characters Remember the good old days, when adventures were underground, NPCs were there to be killed, and the finale of every dungeon was the dragon on the 20th level? Those days are back. Dungeon Crawl Classics don’t waste your time with long-winded speeches, weird campaign settings, or NPCs who aren’t meant to be killed. Each adventure is 100% good, solid dungeon crawl, with the monsters you know, the traps you fear, and the secret doors you know are there somewhere. For the past few years, an ogre that lairs in a cave near the wilderness town of Dundraville has demanded tributes of ale and supplies. The villagers were happy to comply, lest the brute attack them or destroy their property. But recently, the ogre changed his demands. Now he wants gold, building supplies — and captives! When the ogre walked into town only to have his request denied, he flew into a rage. The brute dragged two townsfolk off to his cave, to be eaten for sure! The villagers have no heroes to protect them — so someone must rise to the challenge! Six determined townsfolk have taken justice into their own hands. Can these village commoners defeat the ogre in his own lair before their fellows are eaten?

And then a wizard from a far-off world whisks the heroes away to fight battle of a very different sort, leaving them with a strange neon pink glow around their eyes… Note: This adventure can be used setting neutral or as a means to enter the "Purple Planet" DCC setting.

While seeking an easy score, you uncover a plan to strike a blow into the heart of Lankhmar, and no one is safe from the blasphemous plot. A choice needs to be made.
