Cheng Yan travels through time, only to end up becoming an honorable prince in the Middle Ages of Europe. Yet this world was not quite as simple as he thought. Witches with magical powers abound, and fearsome wars between churches and kingdoms rage throughout the land. Roland, a prince regarded as hopeless by his own father and assigned to the worst fief, spends his time developing a poor and backward town into a strong and modern city, while fighting against his siblings for the throne and absolute control over the kingdom. Join Roland as he befriends and allies with witches and, through fighting and even farming, pushes back invaders from the realm of evil.
Before long, things changed. When she was 14, the refugees rebelled in Silver City while her parents were out doing charity work. Her parents never came back. Nightingale and her younger brother were sent to his father's brother, another branch of the Gilen Family.
In the winter of the same year, Nightingale awakened and became a witch.
With great care, she hid her power, but yet the old Gilen discovered it anyway. He took her brother away, and with her brother's life, he threatened her to follow his command.
Nightingale had no choice but to obey. After being trained by the members of the Thieves Guild invited by the old Gilen, she had to do illegal things for him, which included stealing the contracts and papers from the houses of his business rivals, eavesdropping on the meetings of the City Hall, and, what was worse, even poisoning the water in wine glasses or water tanks of his potential rivals.
