The Map of All Things

After terrible atrocities by both sides, the religious war between Tierra and Uraba has spread and intensified, irreparably dividing the known world. 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 that sends the Soldan-Shah's adoptive son on a quest to find the Key to Creation. Meanwhile, 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. And his wife Adrea is now the wife of the Soldan-Shah and mother of his adopted son.
