In a distant, mysterious fantasy world reminiscent of the Middle Ages, magic and royal power rule side by side. Across a vast, enigmatic continent lie countless kingdoms and territories, each with its own unique culture, customs, and magical traditions. Magic is everywhere on this continent, yet its power is difficult to understand and control. Some gain unmatched glory and strength through it, while others are plunged into endless darkness and despair.
In one small kingdom among many, Aivia, lives a young mage named Luo En. Though born to an ordinary family, he has extraordinary talent and a unique aptitude for sensing and understanding magic. During an expedition into an ancient ruin, Luo En accidentally breaks a magical pact that has been sealed for a thousand years. The pact holds a mouse with tremendous magical power and extraordinary intelligence, who calls himself the Duke of Mice.
Piken, the Duke of Mice, was once the companion of a great mage in ancient times. After a breathtaking magical battle, he was sealed away when caught in the crossfire of dark magic. He knows countless lost magical arts and ancient secrets, but his true thoughts are hidden behind his crafty eyes, making him impossible to read. Luo En strikes a deal with the Duke of Mice: Luo En will break the seal and offer him shelter, and the duke will teach Luo En long-lost magical knowledge. But their partnership draws the attention and envy of powerful factions. A storm is about to engulf them on this mysterious continent.
