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!

Centuries past, Lady Ilse ascended to scion of House Liis by trading the archdevil Mammon what he wanted most: her immortal soul – and a diabolical betrothal. The triumph proved hollow, for every year on the eve of her fell covenant, she was beset by visions of Mammon and her foul promise. Seeking to save herself, she was buried alive, swaddled in the holy symbols of a dozen divergent faiths. This desperate ploy held Mammon at bay for centuries…but a devil can afford to wait a very long time. After hundreds of years, the last of the holy wards has fallen. The devil has come to collect his due. Tonight a storm crashes against the ancient manor house and forgotten spirits rise from the muck and mire. The fallen belfry tolls once more, announcing the hellish fete. As the adventurers arrive to explore the Black Manse, Mammon calls for his winsome bride. He will leave with a soul at the end of the night. The only question is: Whose?

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…

Remember the golden days of role-playing, when adventures were underground, NPCs were there to be killed, and the finale of every dungeon was the dragon on the 20th level? Well, those days are back. Dungeon Crawl Classics feature bloody combat, intriguing dungeons, and no 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 must be there somewhere. In Idylls of the Rat King, goblin bandits are once again attacking the silver caravans, killing innocent miners and stealing cargo. The goblins have taken up residence in an abandoned mine northwest of Silverton. Someone must get rid of them. But this is no ordinary abandoned mine. It was deliberately barricaded generations ago when the Gannu family, founders of Silverton, discovered an unspeakable evil on its lowest levels. And these are no ordinary goblins, for the curse of the Gannu family courses through their veins…

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. But the dome is weak because it has been assaulted by the mythical storm demon Azi Dahaka and his trapped minions, evil creatures that were sealed under the magical dome to keep them from ravaging an unsuspecting world.

Once every decade, the tides of the Empyrean Ocean recede far enough to reveal the highest eaves of a mysterious undersea tower. Long ago this was an eldritch fastness of Sezrekan the Elder, the most wicked wizard ever to plague the Known World, but now the tower is known simply as the final resting place of the fabled Black Pearl – an artifact rumored to bring doom upon all who dare to posses it. Tonight the moon nearly fills the sky, and the tides have already begun to recede. Adventurers have eight short hours to explore the tower before the dark waters return. The fabled Black Pearl will be theirs for the taking…if they can survive the Pearl’s curse.

Villagers have gone missing! A mix of clues, superstitions, and omens point to the brooding citadel of the emerald sorcerer. This silent monolith has sat undisturbed atop a windy ridge for centuries. Legends say that a green-skinned sorcerer dwells there, where he conducts strange experiments and builds enigmatic machinery. His green-skinned constructs patrol the grounds of his citadel, and he is seen only rarely when he ventures out on nefarious errands that end in horrid screams and strange lights coming from his citadel. Now it is time to penetrate his inner sanctum…

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.

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. It is surrounded by an impenetrable force field that cannot be breached - not even by the ghost of the long-dead wizard, who has been trapped within for centuries. Surely there must be great treasure within this magical abode. But how to get to it?

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.

Legend tells of a long-dead empire of sphinxes, ruled over for millennia by a great queen named Ankharet. She fell into darkness and her empire was shattered, as her subjects rebelled and cast her down. Unable to kill her, it is said that they bound her with great magic and buried her in a tomb, to wait for the foretold heroes who would be able to slay her and end her evil forever. Their empire in ashes, the sphinxes scattered to roam the world in bitter freedom, save a single great androsphinx. On the edge of the mysterious Barren Hills, between the mountains and the Great Desert, there is a gigantic statue of a crowned gynosphinx, ancient beyond reckoning. At its feet, a great androsphinx known as Khubsheth the Prophet has dispensed counsel and prophecy to all who come to him for longer than mortal records can tell. The heroes have come to visit Khubsheth, whether for counsel, prophecy or out of curiosity, but as soon as he lays eyes on them, he attacks! Upon his defeat, he tells them that they are the heroes foretold by the legend of Ankharet. Ankharet ruled over a long-dead empire of sphinxes, but she fell into darkness. Her subjects rebelled and cast her down, but were unable to kill her. It is said that they bound her with great magic and buried her in a tomb, to wait for the foretold heroes who would be able to slay her and end her evil forever. Kubsheth the Prophet tells the heroes that they must enter the tomb of the long-dead sphinx queen, kill her, and destroy her cursed crown, an artifact of tremendously evil power.

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?

The city is gripped in fear! The Ripper has returned after a 125-year absence and is once again carving a trail of blood through the slums of Millers Court.

If the heroes are brave enough to enter, will they find the Ripper himself there?

Towering obelisks stab the sky. Monstrous knights with blazing lances prowl the night. Huts burn, and entire villages are taken as slaves to be fed darksome pits. The cries of terror and panic give the horrors a name: the Beakmen have come. But you are no mere peasant or serf, cowering the in the dark. You and your companions are reavers, with bloodied blades and spells wrenched from the dreams of demons. You stride through chaos while others flee, turning your steps towards the great stone obelisk, the source of the beakmen and their alien magics. Whether for the cause of justice or merely to acquire these strange blazing weapons for you own, tonight there shall be an accounting: a blazing brand thrust into The Shadow of the Beakmen.
