Located in the southwest areas of the Land of Fire, these lowlands are inundated with rain, down to the soil being soaked. The arena is a sort of labyrinth of waterlogged ground interspersed with meter-deep water. The water makes running impossible while even partially submerged, and the land proves little better as a foothold; the slick mud comprising the embankments causes anyone moving above 10m/s on them to move 5m forward uncontrollably. Unlike standing on the surface of the water, Supernatural Walking Practice has little bearing on the shifting semi-solid mud.
