As a lack of ekti will cripple both the human and Ildirian civilizations, and the hydrogues refuse to negotiate or even respond to human overtures of peace, their ultimatum is effectively a declaration of war. The humans and Ildirans mount a defense to protect their interests, but the virtually indestructible hydrogue ships and their lightning and ice weapons seem an unconquerable enemy. Arrogant Hansa Chairman Basil Wenceslas, the real power behind the Hansa, installs the young Prince Peter as Frederick's successor. Hand-picked by Basil from obscurity and specially trained for his role as Hansa figurehead, the new King Peter is soon at odds with the Chairman, whose governing style seems more to Peter like a self-serving consolidation of power than a means to lead the human population in a meaningful way. Meanwhile, the sudden appearance of the hydrogues complicates matters for Ildiran Mage-Imperator Cyroc'h; he and his predecessors have kept the existence of the hydrogues a secret for millennia as they plotted a means to neutralize the threat should the hydrogues return. Cyroc'h's own heir, Prime Designate Jora'h, has fallen in love with the human green priest Nira Khali, and Cyroc'h soon comes to believe that her telepathic abilities could be of use to his failing hydrogue plan.
