Sea of Frozen Lives
The Sea of Frozen Lives is the area around the border between the Elemental Plane of Water and the Paraelemental Plane of Ice. Here, the plane is filled with water just above freezing, with the occasional fragment of ice floating still scattered about, of all sizes. Towards the direction of Ice, these fragments grow more common, eventually fused into one mass of ice honeycombed with water-filled passages. Towards the direction of Water, the ice becomes less common and the water warmer.
