The Mad God's Key (Patreon)

This adventure takes place in the River Quarter of the Free City of Greyhawk and was printed in Dungeon Magazine #114. The adventurers investigate matters relating to the Cult of Vecna, which leads them to the Tomb of Blood Everflowing in the Cairn Hills. Barge End is a great dock map that was used as a chase scene in the original adventure. The player versions of these maps will allow them to be placed anywhere.
