Aiah has learned that plasm is more than an energy source. It resonates within the human mind, giving power to heal and to kill. So when she finds an undiscovered, unlimited supply, she dares to meet with the powerful Metropolitan known as Constantine, a mysterious rebel with plans. Together they can use the plasm to rally forces to overthrow the government.

After the war, Aiah must contend with Constantine, the man she transformed into a leader, as he forces her to recruit plasm divers to destroy the Silver Hand and work with a terrifying human-turned-monster that only ventures out of his hole to destroy life, but she also discovers her heritage and what lurks behind the Shield.
