From publisher blurb:
Far below the sunlit surface lie places and things undreamt of by decent commonfolk. Some such things have never seen the light of day, while others have escaped into the Underlands to escape the hated sun. Centuries ago, another settlement stood where Dulwich now stands, and its crumbling remnants yet linger in the endless dark below the town. A wealthy merchant, carrying out repairs in the deepest part of his cellar, has made a curious discovery—a rubble-choked set of stairs leading to who knows what subterranean depth—and needs a band of brave adventurers to explore whatever lies below…
This Dungeon Backdrop is designed for the town of Dulwich in the Ashlar mini-campaign setting but can be easily inserted into almost any fantasy campaign. It is a sequel to Lost Cellar of the Nameless Mage and Forbidden Halls of the Nameless Mage but can be easily used as a standalone dungeon.
