Sphere of Water

Water is the ultimate solvent for life as we know it and the Sphere of Water is as rich with life as the Sphere of Life, just different. Vast forests of kelp and coral cover the distant floor while the surface where the sphere touches that of the Sphere of Air is an enormous ocean dotted with the rare island of elemental earth flung there over the centuries. A vast majority of the Sphere of Water is just that, endless water with no end or any sense of what is up or down.
