From publisher blurb:
Lost to time and battered by the foulness of its surrounds, the decrepit and mouldering Decaying Citadel of the Fated Warlock slowly sinks into the Salt Mire. Wreathed in lurid tales of legendry and foul doings, the lonely citadel is now little more than a crumbling shell, yet peasants tell of its mistress’s great power and great wealth. Atavistic lizardfolk haunt the surrounding fens and bogs and keep casual explorers away, but the legend of the Fated Warlock refuses to die. What yet lurks in her ruined castle? Are unfound treasures lurking therein waiting for those brave and clever enough to find them? And what befell the Fated Warlock herself? Only brave adventurers can answer such questions…
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--all you need is a swamp and some lizardfolk.
