After terrible atrocities by both sides, the religious war between Tierra and Uraba has spread and intensified - the series of skirmishes erupting into a full-blown crusade. Now that the Uraban leader Soldan-Shah Omra has captured the ruined city of Ishalem, his construction teams discover a priceless ancient map in an underground vault - a map that can guide brave explorers to the mysterious Key to Creation. Omra dispatches his adoptive son Saan to sail east across the uncharted Middlesea on a quest to find it. In Tierra, Captain Criston Vora has built a grand new vessel, and sets out to explore the great unknown and find the fabled land of Terravitae. But Criston cannot forget his previous voyage that ended in shipwreck and disaster . . . and the loss of his beloved wife Adrea - who is now the wife of the soldan-shah in far-off Uraba, fighting to survive against palace intrigues and constant threats against her life.
