Players wishing to set the Shackled City Adventure Path in the World of Greyhawk might consider placing Cauldron near the northwest border of Hex 77-U1 on the Living Greyhawk Gazetteer map. With this placement, Cauldron (and the nearby city of Sasserine) would have been established as a secure trade outpost by Sea Princes-aligned merchants about 150 years ago. When the expansion of the Keoish navy checked the ambitions of the Sea Princes 20 years later, the Cauldron/Sasserine colony was forced to survive in a hostile, isolated clime. In the ensuing years, they freed their slaves and abandoned their connection to their former patrons, embracing a culture and political identity all their own.
