Aifra remains in the shadows while the world accuses Russia of orchestrating terrorism. A world war is brewing which the Hekameses must prevent without revealing themselves. They lost a key member, Dr. Cobb, to treachery and Kalki has vanished. Reduced in strength, the Hekameses split up their efforts. Alejandro and Zoya search for the elusive Kalki, the prophesied deliverer of the ages. Chris sets out to track down Aifra's base. The missions are met with tragedies, but they stumble upon the forgotten kingdom of Lumania-a civilization centred around a superhuman ability to manipulate sound. The Hekameses receive intelligence of an imminent raid on Moscow with the goal to flatten the city. They solicit Lumanian support in a rush to prevent this crisis. The Lumanians have survived for centuries on their core principles of pacifism and non-intervention. They are reluctant to change their ways. They speak of a curse of the Mother Earth, Gaia, placed against humanity for its many transgressions and insist it must be borne. The key players stand at cross-purposes as the world braces itself for an apocalypse.
