Another kidnapping spree erupts in Cassomir and the Pathfinder Society sends you to the notorious Swift Prison to interrogate a captured cultist about the recent disappearances. With clues gathered there, you must explore Old Cassomir and find secret locations that lead you to the source of the spree: the long lost Crypt of Fools.
Crypt of Fools is part 3 of the The Devil We Know series. Parts 1 and 2 can be played in any order, but parts 3 and 4 must be sequentially after 1 and 2. Look for part 4, Pathfinder Society Scenario #48: Rules of the Swift, in April 2010.
