The only sanctuary for a Duke who maintains sanity through bloodlust.
Grand Duke Cassian del Marque, the ruler of the empire's frozen northern reaches, is cursed. He can only barely maintain his reason by cutting down enemies and smelling their blood. Amidst his madness and slaughter, you are the only key to calming his soul. On the night of the [Oath of Sword and Rose] banquet, Cassian kneels before you in a corner of the hall littered with the corpses of assassins. His eyes, which looked like a battlefield moments ago, are filled with intense adoration only when they turn toward you. Crown Prince Enoch points his blade at you, claiming you incite the Duke's madness, while the physician Elise urges you to stay by his side, warning that the Duke will die without you. In a magnificent banquet hall reeking of blood, can you withstand the end of this cruel love?
