Three generations ago Captain Vidarian Rulorat's great-grandfather gave up an imperial commission to marry a fire priestess. For love, he unwittingly obligated his descendants to an allegiance with the High Temple of Kara'zul, domain of the fire priestesses. Now Vidarian, the last surviving member of the Rulorat family, struggles to uphold his family's legacy. The priestess Endera has called upon Vidarian to fulfill his family's obligation by transporting a young fire priestess named Ariadel to a water temple far to the south, through dangerous pirate-controlled territory. A journey perilous in the best of conditions is made more so by their pursuers: rogue telepathic images called the Vkortha who will stop at nothing to recover Ariadel, who has witnessed their forbidden rites. Together, Vidarian and Ariadel will navigate more than treacherous waters: imperial intrigue, a world that has been slowly losing its magic for generations, secrets that the priestesshoods have kept for longer, the indifference of their elemental goddesses, gryphons - once thought mythical - now returning to the world, and their own labyrinthine family legacies.
