Halius is a Plainsward, a simple man tasked with a grave responsibility. Leaving his home behind in search of a cure to a disease that threatens to destroy his village, he soon learns that saving his people will be even harder than he feared.

Zebala, a skilled Firemage, takes Halius under her wing—giving him no say in the matter. Through her he learns that his people have been plagued, not by disease, but by Gyanos Yostavro, a half-Demon warrior of such limitless power and savagery that he has subdued his entire homeland merely by existing in it.

Yostavro is a far-off problem, as Halius and Zebala are thrust into a world intent to destroy them before they ever confront the self-proclaimed Lord of Fire. Facing dangers that the Plainsward had never dreamed existed, it is up to the pair to save the Plainswards—and the world—from burning destruction.
