All Oz Carnavon ever wanted was to become a master mage. Except, to do so requires the natural gifts or wealth necessary to secure an appointment to one of the prestigious magical academies in the Core City at the center of the seven realms.

He now travels the length of the Dervan Empire that conquered his homeland, driven by a singular purpose—to find what remains of his people who were carried into slavery across the empire.
