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.

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.

During the Last War, the ancients deployed their war-skiff assault units from elevator platforms that now dot a sector of the wasteland like a ravaged forest of rusted steel stumps. Most of the platforms are buried by the shifting sands or stand as shattered reminders of a war that was once meaningful, but one of these decaying steel stumps still remains partially energized, layered with tunnels below ground, and powered by a unique extra-dimensional reactor core beneath the surface of the planet.

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.

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.

Eons past the fabled sorcerer-kings of Parhok perished in a rain of eldritch fire.

Or has a more sinister power bent their ancient magics to its sinister will? Only the most courageous and cunning of heroes will emerge victorious from Dragora’s Dungeon.

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.

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 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.

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.
