Lux awakens to a world forever changed.

Though the Joined Cities stand victorious in the wake of the Mimic invasion, Shadebinder plots continue to churn in the shadowy depths of the Eastern Forest. Rumors of a new claimant to the Golden Throne threaten to plunge the entire world into war. Voices from beyond the void offer a borrowed mastery of the darkness, but they demand a terrible price in return. To survive the coming trials, Lux will have to put his trust in his steadfast companions. However, when he's forced to confront the sinister origin of his deathly powers head-on, a difficult question will arise.

Can he trust himself?
