In this postapocalyptic fantasy, a sea of sand swallows everything but the past.

In an endless sea of sand drifts the Mud Whale, a floating island city of clay and magic. In its chambers a small community clings to survival, cut off from its own history by the shadows of the past.

The blight of the t richos is infecting the people of the Mud Whale with horrifying speed, and the island seems doomed to become a floating graveyard. But visions of the past may have the power to save the future as Chakuro becomes witness to Shaun and Ouni's private recollections.
