The Sea of Lost Souls extends from the southwest part of Xen’drik to the southeast part of Sarlona and the east coast of Argonnessen. It is known as a perilous sea for sailing, and its reputation for being haunted by numerous ghost ships gives it its name. Though its southernmost reaches are covered by the unmelting Everice, it extends all the way to the equator, which is considered the dividing line between it and the Barren Sea (in the east) and the White Sea (in the west, near Sarlona). The Sea of Lost Souls is also said to be the deepest of Eberron’s oceans—some legends speak of a trench extending miles beneath the surface, a region so dark that the darkness itself is alive.
