From publisher blurb:
For a level 16 party!
Rivermarch Keep use to be a place of law and progress - the meeting grounds for the prestigious Iron Conclave. That all changed when the members of the Iron Conclave mysteriously disappeared the night of their 144th meeting. No ranger could track them, nor oracle divine them, and their disappearance has been a mystery for two decades now.
As it stands, the region is on the verge of war. Each noble house blames another for the disappearance of the lords that comprised the Iron Conclave. The PCs need to explore Rivermarch Keep for clues to discover what caused the lords to vanish that fateful night, and keep peace in the region!
Devils in the Details includes PLAYER SAFE MAPS - maps you can show your players for each encounter area that does not reveal important details like the locations of traps, treasure, or hostile creatures.
