Lorath Bay is a large bay on the northwestern coast of Essos. Around the southern edge of the bay lies the Hills of Norvos. The Free City of Lorath sits at the mouth of the bay in an archipelago. The bay opens into the Shivering Sea.
Leviathans, seals, and walruses live in Lorath Bay. While the Lorathi claim the bay, they lack the strength to prevent Braavosi fishing fleets and Ibbenese whalers and sealers from entering the waters. The western shore of the bay is controlled by Braavos.
The shores and isles of Lorath Bay were inhabited in antiquity by mazemakers, hairy men, and Andals, the latter of whom used longships. The Andals were defeated in the Scouring of Lorath, however, and the region was eventually colonized by the Valyrian Freehold.
