The Shadow Fane (System Neutral Edition) (2019)

From publisher blurb:

Evil is everywhere and humanity must be ever vigilant against its slow encroachment into all that is great and good. Small cults—dedicated to ancient, blasphemous powers—lurk throughout the world ready to carry out their dark patron’s bidding. One such small cult dedicated to Braal, god of hate, malice and revenge, dwells in the Shadow Fane below Languard’s High City. The cultists kidnap and murder in their dark god’s name, but recently they made a mistake that threatens their very existence. Instead of kidnapping a beggar the cultists accidentally kidnapped the daughter of a wealthy merchant and he is offering a handsome reward for his daughter’s safe return.

This Dungeon Backdrop is designed to work with the Duchy of Ashlar and Gloamhold campaign setting but can be easily inserted into almost any fantasy campaign.
