The Sea of Dreams is one of the two masses of water comprising the Inner Sea of Ulthuan. As the eastern half, it surrounds the Island of Flame, and breaks against the coast of Saphery. It is also the first sea one enters when sailing inward from Lothern, Eataine.
Since the destruction caused by Grom the Paunch to Ulthuan's waystones, the Sea of Dreams has become more unpredictable. Now it is a place of ghosts and evil memory, for the magic that kept local Asur safe has faded, and the terror of the past lives again in their dreams. When sailing across its waters, one can feel the unnatural sense of time slipping away, and the brooding shadow of ancient things pressing against ones thoughts.[2a]
