Ilimys-Erethor Cut

The Ilimys-Erethor Cut is a subsurface ocean channel connected to the surface ocean Erethor. This extensive channel spans several hundred miles in length and ranges from a mile to ten miles in width. It serves as a safe harbor to weather storms, a refuge for pirates, and a haven for oceanic and subterranean creatures. Numerous passages lead upward from the channel into the depths of the Underdark region Miryeril.
