On their way to the first Circle temple in Gyongxe, mages Briar, Rosethorn, and Evvy pay a visit to the emperor's summer palace. Although treated like royalty when they first arrive, the mages soon discover that the emperor plans to invade Gyongxe, posing a fatal threat to the home temple of the Living Circle religion. Accompanied by one of the emperor's prize captives, the three mages rush to Gyongxe to warn its citizens of the impending attack. With the imperials hot on their trail, Briar, Rosethorn, and Evvy must quickly help the country prepare for battle. But even with the help of new allies, will their combined forces be enough to fight the imperial army and win the war?

While Briar and his teacher Rosethorn are helping the locals in Chammur, Briar realizes that all is not as it should be in Chammur's streets. As a former 'street rat' himself, he tends to have an interest in the affairs of local gangs. He discovers a gang known as the Vipers roaming through territory not their own. After further investigation, Briar discovers that the Vipers are the pet gang of a local Noblewoman. While Briar investigates the Vipers, he discovers Evvy, a local girl with stone magic. At first, she runs away from him, but she gradually learns to trust him. When Evvy singularly refuses to study with local stone mage Jebilu Stoneslicer, Briar takes her training in hand himself. The Vipers attempt to kidnap her many times, so Lady Zenadia doa Atteneh can use Evvy's powers as a stone mage to further increase her riches. When they finally kidnap her, Briar comes to her rescue
