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.

As it wings back across the city walls to drop behind the Duke’s mountain-top keep, all who watch know it alights in the Magnussen family crypts, where the devilish secrets of thirteen generations have been buried and forgotten – until now… This adventure module also includes The Balance Blade, a short level 2 adventure in which a wizard’s patron makes a simple request: travel to another plane to retrieve a legendary blade of neutrality.
