Apprentice wizard Ethan Tolyn survived the difficult journey to the town of Ironbridge, which marks the boundary between civilization and wilderness. But Ethan finds the reality of life on the frontier to be different than his expectations, and he rapidly finds himself drawn into another dangerous adventure. Accompanied by Selenna and Bella, and some new allies, the young arcanist sets out on a quest to recover a cache of forgotten lore from a long-faded age. But what Ethan doesn't know is that there is more to this mission than he or his employer expects, and that a dangerous adversary is also interested in the secret of the towers of Khormur-Dhain.
