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.

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.

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.

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. But this time is different. The Great Beast strikes with intelligence: bands of faceless gray-robed men emerge from the tenebrous depths, herding the beast’s roaming tentacles before them. 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 adventure is intended for 2 to 3 3rd-level PCs originally from Lankhmar, but can easily be adjusted to accommodate adventurers from other locales. Guidelines are also provided for scaling the adventure for up to six PCs. The events of this adventure lure the party from their home in the City of the Black Toga to an abandoned watch tower on the coast of the Inner Sea, not far from Ool Hrusp. After completing this scenario, they may find reason to further adventure in the Forest Land.

The rumors are true! The secret cave of the mystics holds a hoard of treasure vast enough to buy the kingdom seven times over. Gold coins piled as high as snow banks! Gleaming swords and jewel-encrusted wands crackling with arcane energy! Precious gems as large as your fist! The only thing standing between your present circumstances and a life of fabulous wealth is a pesky, slumbering elder god with a penchant for consuming entire worlds, an endless army of vat-grown hybrid monstrosities, a veritable tidal wave of disembodied eyes with awesome powers, giant acid worms, and a curse with the power to rip the still-living eyes from your skull. Do you have the mettle to stare down a god or will your eyes forever adorn the vault of The One Who Watches From Below? The winner of the Mystery Map Adventure Design Competition!

At the base of the falls, behind a massive curtain of water, is rumored to be the cavern lair of a great wyrm.

But what role do the heroes play in a blind shaman's prophecy foretold a century ago?

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.

Will you stand with the city, or risk letting it descend into chaos?

On the Purple Planet, amid the frosted Ancestor Peaks, the adventurers have encountered a small pyramid thrusting skyward from the bottom of a ravine. This is the Tomb of Dust, one of the ancient cairns found throughout the area. Here, the PCs find deadly puzzles, encounter the Moth Mother and her hungry brood, and face the tests of Anh-Tho the Learned, a forgotten scholar of a bygone age. If they manage to thwart these dangers they gain access to Anh-Tho’s Archive, a perilous repository of potent lore!

When the Purple Planet began its slow decline, factions arose to vie for the final resources of the dying world. In the days of the Last Wars, the Ascendant Masters used their knowledge of cybernetics and genetic engineering to create increasingly powerful and grotesque biological weapons. One such weapon was Sotark the Destroyer of the long lost House Memniscene. Damaged and placed in a cryogenic regeneration capsule, Sotark has slept away the ages while the House above him eroded away under the weirdling sun. Over time, the capsule has failed, but still Sotark sleeps on, diminished, but not destroyed.
