From the back of the book:
The Price of Greed
In the center of Lake Encarthan looms the dreaded Isle of Terror, accursed land of mystery and treachery. Hidden within the island's negative energy storms, the secret treasure city of the wizard-king Tar-Baphon has lain sealed for centuries. Now masked cultists have opened the golden city of Xin-Grafar to claim the wealth of the legendary city for the Living God Razmir. Can the PCs track the cultists through the poisoned swamps and blasted wastelands of the Isle of Terror to the City of Golden Death itself? And what forgotten dangers will oppose them as they struggle to prevent a dark faith from spreading across the world?
City of Golden Death is an adventure for 5th-level chararacters; it is written for the Pathfinder Roleplaying Game and is compatible with the 3.5 edition of the world's oldest RPG. The adventure features a mix of wilderness and dungeon sites and includes a race through a ruined, golden city to stop evil cultists before the city floods with molten gold!
This adventure is set on the legendary Isle of Terror in the Pathfinder Chronicles campaign setting, but it can be easily adapted for any game world. It can be used as a stand-alone adventure or as the final chapter of the Price of Immortality trilogy, following the adventures Crypt of the Everflame and Masks of the Living God.
