Great Sea

The Great Sea, also known as the Everdeep, is an ocean which surrounds the lands of the Overworld on all sides. This sea's depth is many times greater than that of the seas which run between the continents of Tarn. In fact, some scholars say that the seafloor is ten thousand leagues from the surface. This sea is said to be the home of Yorok, the Father of Serpents, as well as Raegos, the sea-god of the Avalar. Everdeep is encircled by the Teeth of Ice, which mark the edges of the world.
