In the wake of the destruction of Psychon, the Moon approaches the planet Ekimmu, a world visited in the past by Psychon expeditions, an ocean world with an abandoned city hidden below its blood-red waters.

 

Maya, Daughter of Mentor, accompanies the Alphans as they explore the planet and the possibility of settling there. Not yet an Alphan, Maya seeks clues to the fate of her people.

 

Together they find that the waters of Ekimmu are now the medium of madness, desperation and rage. The Alphans face a terrible choice: eternal torment or death.
