Sea of Dorne
The Sea of Dorne is a large sea along the southeastern coast of Westeros. It is bordered to the north by Cape Wrath in the stormlands, to the west and south by Dorne, and to the east by the narrow sea. The river Wyl flows into the sea.
Some maesters, such as Cassander, believe the Sea of Dorne was once a smaller inland sea separated from the narrow sea by salt marshes, and that the narrow sea eventually flooded into this once-freshwater sea through the Song of the Sea.
