The home city of the Dark People, which changes location according to the winds and the ocean currents. It can therefore only be reached by Shadow Ship, or the Cloudships built by the Azadi. The city has an organic look and feel, and seems to be built of or within a network of twisting tree trunks and vines. It extends deep underwater, and is lit by phosphorescent lights.
Though Zoë Castillo, April Ryan, Brian Westhouse and Crow all visit the city, we only see a few areas of it. There are plenty of twisting corridors, and at one point the characters pass through a room where the Dark People are resting, drifting in midair, though most of our time is spent in the Dark People's Library.
