From publisher blurb:
The past rarely stays buried forever, and forgotten and forbidden things have a way of finding their way back into the light. 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 but can be easily used as a standalone dungeon.
