From publisher blurb:
An Expert adventure for Shadow of the Demon Lord
Constructed by one of Rûl’s most notorious wizards, the Dungeon of the Damned travels from place to place. Its old wooden doors, bearded with rusting nails, scraps of paper, and dire warnings, appear without rhyme or reason and then disappear. Through the doors, adventurers will find eleven deadly levels offering opportunities to explore, discover, and confront evils so profound, so terrible their mere existence imperils the world. Characters of any level can risk their lives descending into these depths, but even the mightiest among them might find the challenges too deadly and lose heart. Whether presented as a one-shot adventure or an extended mini-campaign, none who enter the Dungeon of the Damned leave unchanged, if they leave at all.
Dungeon of the Damned: Halls of Death reveals the deadly third level of the infamous dungeon. Here, the Mad Wizard interred any wicked or foolish enough to offend him. He trapped them here and made sure that not even death could release them. Dark magic ensures their souls stay here, trapped in rotting, corrupted bodies. Characters entering this dungeon must navigate its perils and battle their way through an ocean of undead if they would descend deeper into the Dungeon of the Damned!
