Emperor Cassel is obsessively in love with the beautiful Julian. To possess him, he destroys Julian’s entire family, showers him with treasures, and eventually imprisons him in the Star Tower. Cassel then crowns Celia, a woman who resembles Julian, as empress. Believing herself to be his true love, the jealous Celia mistakes Julian for a slave and kills him with the help of her noble friends. When Cassel discovers the truth, his revenge exposes a conspiracy led by the Empress Dowager to overthrow the empire. But Julian is not truly gone. Revived through an alchemical ritual, he returns for vengeance—and ultimately kills Cassel with his own hands, avenging his entire family.
