In the Kingdom of Evangale, power is defined by "Magius"—the ability to manipulate magical energy. Prince Deor Fluenti, however, was born "incompetent," lacking even a trace of this energy. Ostracized by his half-siblings and ridiculed by the court, Deor relies on his brilliant tactical mind and intense physical conditioning to survive. But as a demonic threat looms over the kingdom and a conspiracy threatens the throne, Deor discovers that his lack of Magius might be tied to a darker, more ancient secret. To save the people who despise him, he must embrace a power far more dangerous than magic.
