The Dragon King's Secret Daughter

Elena died protecting Balthazar's Heartscale after raising Aria to three. Aria returns the scale to the dragon castle. Balthazar, consumed by rage, is softened by her pure heart. Seraphina stages a rebellion. A memory stone in Aria's doll reveals the truth. Enraged, Balthazar crushes it. At the baptism, Aria—a worthless half-blood—awakens Dragon-God power. The tyrant becomes a devoted father.
