The Moontide has come and the Leviathan Bridge stands open: now thrones will shake and hearts will be torn apart in a world at war.

A scarlet tide of Rondian legions is flooding into the East, led by the Inquisition’s windships flying the Sacred Heart, the bright banner of the Church's darkest sons. They are slaughtering and pillaging their way across Antiopia in the name of Emperor Constant. But the emperor's greatest treasure, the Scytale of Corineus, has slipped through his fingers and his ruthless Inquisitors must scour two continents for the artefact, the source of all magical power.

Against them are the unlikeliest of heroes. Alaron, a failed mage, the gypsy, Cymbellea, and Ramita, once just a lowly market-girl, have pledged to end the cycle of war and restore peace to Urte. East and West have clashed before, but this time, as secret factions and cabals emerge from the shadows, the world is about to discover that love, loyalty and truth can be forged into weapons as strong as swords and magic.
