Since time immemorial, the people of Golarion have been setting out into the sea to gather resources, ply their trades, and seek secrets both above and below the water. Explore the failed utopia of the island of Hermea, the home of deadly Red Mantis assassins on Mediogalti Island, the mysteries of the Mordant Spire grown from the remains of a dead god, the countless pirate-scoured islands of the Shackles, or the dangerous depths of underwater regions.

Each entry within this gazetteer includes the history, culture, and current events of the region, as well as a major city to include in a variety adventures. The book also includes new character options and a fold-out poster map!
