For a thousand years Mezar-Kul has known only war, and now the Overlord reigns supreme. From his gargantuan metal fortress he rules the blasted remains of the planet’s last city. Hope seems lost – until visitors arrive from a distant world, bringing uncanny, magical powers. Your adventurers must pick a path through twisted ruins, ancient missile silos, strange monorail systems, and a conflict with four deadly factions to save a world – or destroy it! Note: This adventure does require that the party have some access to spell casting, whether through an item or class that requires a spell casting roll.

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.

At the end of a forgotten back alley, in the weird and otherworldly marketplace of faiths known as the Bazaar of the Gods, stands the ruins of a forgotten chapel. Once the cult of the Carnifex was celebrated throughout the City of a Thousand Gates. But a band of holy warriors rose against the cult of executioners and torturers, casting down her signs and scattering her devotees to the winds. The fate of the cthonic goddess, and – more importantly – her fabled jewels remains a mystery…until this night. Set amid the sprawling decadence of Punjar, Jewels of the Carnifex offers low-level adventurers a chance to plumb the mysteries beneath the city’s soiled streets, explore forgotten crypts lavished with weird artifacts, and – for the quick and daring – claim the lost Jewels of the Carnifex!

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.

A member of your gang awakens in an alleyway with foggy memories of a deal made, a job taken, a partner slain, and a heist planned. They struggle to remember the details, but you all agree that breaking into an abandoned temple should be a simple matter – in and out. Yet the heist is on a collision course with something sinister. What begins as an easy job becomes anything but, as you confront cultists, vengeful spirits, and the servitors of a long-forgotten god. 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. Will you stand with the city, or risk letting it descend into chaos? Curse the gods of Lankhmar for their cruel joke that, in the shadowed alleyways of Lankhmar, there is no such thing as a “simple matter.” Officially licensed from the estate of Fritz Leiber.

In Temple of the Dragon Cult, the characters are called in to pursue a dragon that the king’s army was able to wound but not kill.

When the Purple Planet began its slow decline, factions arose to vie for the final resources of the dying world.
