Fiction:The Firmament/Plane of Water

The Plane of Water is one of the four regions of the Elemental Plane, currently ruled by the serene elemental lord Tritonomarth.

Description
The Plane of Water is an immense spherical shell of salt, fresh, and brackish water, with these being divided by powerful currents which permeate the demiplane. The depths of the realm possess solid land in the form of titanic coral structures, while attempting to surface it only results in the currents blowing whoever is attempting it back to the depths.

Inhabitants
Water elementals call the Plane of Water their home, and generally tend to defend it aggressively against any intruders, be them other elementals or outsiders. Due to the plane being completely submerged in water, only those able to breathe underwater are able to survive there.

The brine wyrms are the True Wyrms native to the Plane of Water.
