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!

Evil lurks beneath the ocean! For years it has slumbered, but now it rises once again, threatening to wash over the surface world like a monstrous wave.

Can they stem the tide in time or will they lose themselves forever to the Sea Change curse?

Summoned by a coven of foul witches, the adventurers are bid through the Black Gate and across the multiverse, in pursuit of the crown of the fallen Horned King. There, in the icebound gloom of Thrice-Tenth Kingdom, they must pit their wits and brawn against his dread servants.

Whatever your answer, the land beyond the Black Gate is sure to present a grim challenge for the even the hardiest of adventurers!

At long last, the first adventure ever published for DCC RPG is now available! This is the updated second printing that was first released at Gary Con 2014. It features a fresh edit and several new pieces of art! High above the windswept moors and darksome woods, the village of Hirot is under siege. Each night, as the sun sinks beneath the western mountains and the candles burn low, a devil-beast stalks the village streets, unleashing its savage fury on the living. From warlord to pauper, crone to child, no one is safe. Defeating the immortal hound will require more than mere blades or even spells.

While investigating rumors of a dangerous blue dragon wreaking havoc in the deep desert, the heroes tumble under the sands into the magically sealed dome of an ancient palace. The temporarily weakened dome reseals above them, and they are left to explore the golden palace of Zahadran, once seat of power for the legendary Caliph Ardishir the Magnificent.

Many centuries ago, a band of paladins fell from grace. These blackguards were defeated after a great battle and their grim fortress, the Iron Tower, was razed. A small abbey was established near the ruins, where generations of monks mixed ancient eldritch wards, mighty clockwork traps, and multiple fail safes to build the Iron Crypt of the Heretics. Three mighty vaults ensured that its evils would be sealed for all eternity. But unbeknownst to the brotherhood, their impregnable crypt had a single weakness: the very monks that had built it, for they knew its secrets. When a devourer stole into their abbey, the profane beast forced the monks to help it inside the Iron Crypt. It successfully broke into the first of three vaults, releasing an army of wights. The story of the devourer and his wight army is told in Dungeon Crawl Classics #12: The Blackguard’s Revenge. Now, in the Iron Crypt of the Heretics, the heroes must venture into a crypt designed by the world’s greatest thieves, magicians, and seers, solve its puzzles and deadly traps, and seal it once more from the outside world.

Lady Elisabeth Pendour beseeches the heroes for their help. They must recover a key that was on her husband’s body when he perished trying to clear an ancient tower. The tower was once a coastal fortress, but now it lies in ruins, occupied by black-feathered rook harpies who worship a foul carrion crow demon. Lord Pendour sought to free his subjects from fear by clearing the rampaging rooks from their nests. But he failed, and unless the heroes can recover his body, the crow god will come for his wife, too…

The Characters come across an ancient wizard's tower. The nearby keep has been reduced to rubble over the ages, but the tower is in perfect condition.

Surely there must be great treasure within this magical abode. But how to get to it?

It has been years since the last virgin was sacrificed: and now the pit beast awakens once more! Every generation it stumbles forth on undulating tentacles from its resting place deep below the great ravine, its towering blubbery mass ravaging the land before returning to slumber for decades.

The enigmatic people of the pit live despite the passage of ages! The earth shakes each night as they herd the primordial tentacles ever further, while the villagers ask: is any man brave enough to put the sword to this menace?

This new version of the classic adventure is completely updated to 3.5 edition. In The Lost Vault of Tsathzar Rho, a defenseless village asks the characters to slay an out-of-control ogre. Sounds easy enough. But the ogre, who used to be nothing more than a nuisance, has become crazed and psychotic. When the characters arrive at its cave, they find a subterranean portal has connected the cave to a much larger underground complex. Something in that complex has transformed the ogre and many other local creatures into fiendish marauders. In fact, it’s the lost vault of Tsathzar Rho, an ancient wizard and prophet of the Outer Gods, who are gathering their foul minions for battle.
