Instrell Bay is a large body of water separating the High Kingdoms of Tysan and Rathain. It contains the island of Islandwynne and Blackshear Isle, and the cities of Castle Point and Narms are described as the major port cities (though there are six other cities on this bay). A trade road runs along almost the entire shoreline from Westfen in Rathain to Dyshent in Tysan.

Before the events in Curse of the Mistwraith, ships still regularly cross the bay, although Traithe remarks that it took him six days to find a captain willing to sail up the coastline from Castle Point.
