The Elemental Plane of Water, the Boundless Sea, is part of the Inner Sphere and composed almost entirely of fresh and salt water. It surrounds the Plane of Air and is in turn surrounded by the Plane of Earth. Detritus from other planes provides pockets of air and solid material, and it is perhaps the most hospitable of the Elemental Planes for extraplanar travelers.
The Plane of Water is a truly immense spherical shell of salt, fresh, and brackish water. On one side is the Plane of Air, which provides most of the light for the plane, and near which most of the plane's fresh water is located. On the other extreme is the Plane of Earth, where the waters of the plane near total darkness and their highest level of salinity. At these borders the elements merge, and occasionally large pockets of air or pieces of earth and rock break off, scattering into the waters of the plane. It is in these pockets of air and stone that most non-natives make their homes.
A number of unusual locations and phenomena exist within the Boundless Sea, such as the Forest of Oils, a vast collection of floating spheres composed of diverse chemical substances, and the stars Axtarr, Firros, and Palixna, spheres of flame of unknown origin that hang unquenched in the waters of the plane.
For obvious reasons, this realm is inhabited almost exclusively by aquatic and other water-breathing creatures. The race of genies known as marids control a vast empire, in nearly-constant warfare with the native sahuagin. In the darker depths, cyclopean kraken and brine drakes make up its less innocuous denizens. Beyond these larger populations, small settlements of water mephits, tritons, merfolk, and a staggering variety of more mundane aquatic life makes its home here.
The water genies known as the marid are easily the most dominant culture on the plane. Although they lack a strong, central ruler, they live in large tribal groupings whose territories span from the light-filled regions near the Plane of Air to the twilight near the Plane of Earth.
The sahuagin of the Plane of Water are actually not natives, having traveled there from Golarion in a massive exodus millennia ago. Upon arrival they made war on the fractured marid civilization, attempting to gain an empire for themselves. Once they achieved their objective, however, they fell into infighting and eventual civil war. Now the sahuagin inhabit the darker reaches of the plane, grouped into small kingdoms controlled by tyrants or mutant warlords who long to re-establish their lost empire.
These titanic cephalopods can be found in the darkest depths of the plane, locked in a constant wars with the brine drakes. They are occasionally forced to the lighter areas, much to the horror of the marids and other inhabitants of these regions.
The eternal opponents to the diabolical kraken, brine drakes are the only native species of dragon on the Plane of Water. They live in isolated fiefdoms in the dark borders of the plane. The greatest of their kind is the great earth lord Kelizandri, thought by some to be the semi-divine offspring of a brine drake and an unknown minor deity. He rules over the Brackish Empire, Kelizandrika, located adjacent to the dispersed sahuagin kingdoms.
The Plane of Water is home to numerous species beyond the dominant ones, both native and immigrant. Merfolk are immigrants to the plane, having settled here at an unknown date, and live in carefully hidden settlements throughout its expanse. In the unlit waters close to the Plane of Earth, deep merfolk can be found. Undines, likewise descended from immigrants to the plane, live in communities throughout the Plane of Water. Although they are scattered and often found living among the other races, rumors claim that they are planning to unite to form a major power of their own.
In addition to civilized societies, the Plane of Water is home to marine creatures of immense size. One such creature is the Lion's Mouth, a sapient jellyfish-like creature composed of billions of aware and perceptive organs, which lives within a kelp forest stretching from the Plane of Earth nearly to the Plane of Air, where the jellyfish's bell floats. Lure is an anglerfish thirty-five miles long that feeds by filter-feeding entire towns and pods of whales. A town, the ceratioidi trading port of City-on-Lure, exists on the creature's back. Other beasts of similar size include the Chiming River Dragon and the Void Mosasaur.
