The Elemental Plane of Water is one of the four elemental planes in the Dungeons & Dragons universe, representing the essence of water. It is a vast, endless ocean filled with various aquatic landscapes, including deep trenches, coral reefs, and floating islands. This plane is home to numerous water-based creatures, such as merfolk, water elementals, and sea serpents, all thriving in its fluid environment. In the Elemental Plane of Water, the laws of physics differ from those in the material world. Water flows freely, and beings can swim or glide effortlessly through its depths. The plane is often depicted as a place of beauty and danger, where adventurers may encounter powerful entities like elemental lords or face challenges like treacherous currents and whirlpools.
