The Vril has changed everything. The kingdom of Greater Argovan stands on the verge of an industrial age ushered in by the mysterious energetic substance. But revolutionary technology brings revolutionary ideas. When Master Alchemist Castamar’s apprentice is wounded by a terrorist bomb, he demands answers.
Cast’s search leads him to the Heron Kings, folk heroes of old thought lost to history and legend. But some legends die hard. Ellyx, the band’s thief and forger, joins Cast to hunt the terrorists down and plumb the depths of his past for clues. When they learn that fanatics led by a shadowy Duchess have devised a terrifying variant of Vril that can decimate cities, Cast and the last of the Heron Kings must race to prevent mass destruction.
