Text Version A written companion to this chapter — for accessibility, screen readers, and search.

Humanity has rebuilt civilization beneath the oceans, but the depths are already claimed. When an underwater city is destroyed by the Othryx, an alien species that sees humans as a threat to its world, the United Underseas Nations deploys its most advanced warship: the Deep Sea Cruiser Ryujin. Its crew must confront a powerful enemy while uncovering whether this war is a fight for survival or a conflict that could still be stopped.
