In the remote and mysterious magical medieval world, the world is ruled by magic and royal power. On a vast and mysterious continent, there are many kingdoms and territories, each with its own unique culture, customs and magical inheritance. The power of magic is omnipresent on this continent, but it is elusive and difficult to control. Some people gain supreme glory and powerful power because of it, while others fall into endless darkness and abyss because of it.
In Aivia, a small country among many kingdoms, there is a young magician named Ron. Although he comes from an ordinary background, he is extremely talented and has a unique perception and understanding of magic. During an expedition deep into the ancient ruins, Ron accidentally unlocked a magical contract that had been sealed for thousands of years. Sealed in the contract is a mouse with powerful magic and super intelligence, who calls himself the Mouse Duke.
The Mouse Duke Piken was once the partner of a great magician in ancient times. After a thrilling magic war, he was affected by evil magic and was sealed away. It knows countless lost magical skills and ancient secrets, but its inner thoughts are hidden in its cunning eyes, making it difficult to guess. Ron reached an agreement with the Mouse Duke. Ron would lift the seal and provide asylum for the Mouse Duke, and the Mouse Duke would teach Ron the long-lost magical knowledge. However, their cooperation has attracted the attention and covetation of all forces, and a storm surrounding them is about to set off in this mysterious alien continent.
