A saltwater swamp and bayou region that technically separates Ofrenia from the Rimihuican mainland. Located south of Ofrenia, appearing as a cloudy white band between the Gray Sea and the Oblivion storm to the east. The Groyza — swamp ogres whose mottled skin disappears into the brackish shallows — are the dominant presence here. They were here before Ofrenia named the place and show no interest in the boundary it supposedly marks.
