In a world where the breath of ancient gods still lingers, Elyndra is a realm of impossible beauty and hidden peril. Though ages have passed since the Seven Divine walked the land, their presence remains etched into every storm-lashed coast and emerald valley. The fragile peace is shattered when Kaelrin, a child born of a forbidden union between a mortal queen and Kaelith, the Stormborn King, enters the world amidst a tempest that splits the heavens. Marked by a lightning-bolt scar and carrying the spark of divinity, Kaelrin is a "mortal mistake" that the heavens are determined to erase. As vengeful gods launch deadly trials against him, Kaelrin must decide if he will embrace his divine blood to survive or stay true to his mortal heart.
