The Gilded Sea separates the main continent of Serrade from the desert subcontinent of the Rathsian Empire. It holds many islands that used to be ruled over by the Kender. Many of these islands are used as hideouts for pirates and hermetic wizards. Trade from Lothar and Riverhold enters Rathsia through these waters.
The waters of the Gilded Sea are dangerous, filled with mercenaries, and pirates. Those looking to sail them would do well to see themselves well armed.
