The Thaylen Sea is north of the Nexus of Imagination. It is very close to the Glasswater Deep and Luminous Shallows of the Sea of Lost Lights, although no direct waterways are visible in the available maps. Nazh marked the location of Thaylen City on the edge of the sea; northwest of the city there is a lake which Nazh hates. The lake corresponds to an island in Longbrow's Straits in the Physical Realm.
