Ten years ago, human dancer Lydia was murdered by Queen Aurelia and three others at Dragon King Manor. Her little sister Elara witnessed the crime. To avenge her, she cut off a finger to train fiercely in the Dragon Sacrifice Dance. A decade later, as Elara Vile, she became a top dancer and plotted to marry into the manor. Playing on human weakness and dragon rules, she settled scores one by one: Mara exiled, Celeste disgraced, Seraphina killed by reversed dragonfire, and Aurelia cornered. Dragon King Adrian fell for her. After revenge, Elara learned Adrian never looked into her sister’s death. She shot him at their wedding, exposed her decade-long plan, and left.
