The Third City is the underwater city of the Maerum that April is taken to after the sinking of the White Dragon nearby. Distinctive for its fantastic tall spires, it is located near to the island of Alais in the Sea of Songs, not far from the reefs. Its name could indicate either that it is the third of three or more current Maerum cities, or that it is the third city they have had to build after the destruction of previous ones.
