Medieval fantasy: "Eternal Day Empire" and "Ye Yuan" confront each other across the border. The empire believed in "light" and built thousands of mirror towers to gather sunlight; the night wall was always dark, breeding shadow magic. Light and shadow are not good or evil, but two primitive energies that can be refined by the human body - "Yao" and "Darkness". Assassin here is not a profession, but a "contract": sacrificing one's own destiny in exchange for an absolutely established "kill"

The continent called "Iserland" is shrouded in a layer of "black fog" that persists all year round, and the sun only shines faintly on the edge of the horizon. Civilization only exists in seven "Lighthouse Cities", ruled by the ancient church "The Holy Order of Radiance". Hidden in the black mist are "reverberations of the past" - indescribable whispers and alienated existences. They are not gods, but "forgotten realities", and those who come into contact will gradually lose themselves.
