The Worldsea

The third part of the three-part afterlife, following the Pastlands and the Mists. The Worldsea is the name used in the Plagued Islands. In the Mists of Bressel, it's known as the Becoming. People visiting the afterlife by dreamflower can't reach the Worldsea, and the fully dead in the Mists can move between Mists and Worldsea in a limited fashion. In the Worldsea, you seem to become part of everyone else that has ever moved on.
