The greatest treasures of the world of Golarion lie buried in the crumbling ruins of lost cities, beckoning adventurers from all the lands of the Inner Sea to rescue them -- or die trying! Lost Cities of Golarion presents six treasure-laden ruined settlements ready for your campaign, from the jagged, ghost-haunted Sun Temple Colony on the lost continent of Azlant to the Spires of Xin-Shalast in ruin-choked Varisia to desert-buried seats of lost pharaohs, subterranean Shangri-las, crashed sky cities of long-dead empires, and beyond. Each detailed treatment comes with a full-page map of the lost city, plenty of adventure hooks to draw your players to the action, maps of key interior locations, encounter charts, statistics for important local characters, and more! Each of the six locations revealed here also holds a famous legendary treasure, presented in full detail using the Pathfinder Roleplaying Game rules.
