Elemental Plane of Water
The Plane of Water is an endless sea, called the Sea of Worlds, dotted with atolls and islands that rise up from enormous coral reefs that seem to stretch forever into the depths. The storms that move across the sea sometimes create temporary portals to the Material Plane and draw ships into the Plane of Water. Surviving vessels from countless worlds and navies ply these waters with little hope of ever returning home.
A warm sun arcs across the sky of the Plane of Water, seeming to rise and set from within the water at the horizon. Several times a day, the sky clouds over and releases a deluge of rain, often accompanied by spectacular shows of lightning, before clearing up again. At night, a glittering array of stars and auroras bedecks the sky.
The weather on the plane is a lesson in extremes. If the sea isn’t calm, it is battered by storms. On rare occasions, a tremor in the planar firmament sends a rogue wave sweeping across the plane, swamping entire islands and driving ships down to the reefs.
Any land that rises above the surface of the sea is hotly contested by the few air breathers that live on the plane. Fleets of rafts and ships lashed together serve as solid ground where nothing else is available, although most natives of the plane never break the surface of the sea and thus ignore these habitations.
