"Explore a Dungeon Beset by Peril

Beneath the city of Waterdeep, a sinister dungeon awaits adventurers brave enough to face its perils. Created ages ago by the wizard Halaster, the sprawling dungeon is a lair for terrible monsters and ruthless villains. In the dark chambers, they hunger for victims and plot the downfall of those who dwell on the streets above. Who will unravel the twisting labyrinth to reveal its secrets, claim its treasures, and stop the foul machinations of the dungeon's denizens?

As well as a tie to the D&D Encounters™ season The Elder Elemental Eye.™ In addition, this book provides the ingredients to run a classic dungeon delve, including enticing treasures, deadly traps, a wide assortment of monsters, and two double-sided, full-color poster maps."
