In an alternative France of the late 19th century, magic is prohibited by law. Magicians called "cursed" hide to avoid execution or imprisonment. Paris shines with the light of progress, but in its shadow live those who still keep magic.You are a person with the gift of seeing the past through touch with objects. This talent came from your father, a scientist who was executed for trying to learn magic. Since then, you have lived a double life: by day, an ordinary student of the Sorbonne, by night, a hunter for the secrets that the city hides in its dark alleys.One day you accidentally witness a murder in the Latin Quarter. At the crime scene remains a symbol drawn with blood, which disappears as soon as you touch it. The same evening you find a letter from his father, where he mentions "The Key of the Night", an ancient artifact capable of bringing magic back into the world.In search of answers, you meet Laurent Duvern, a mysterious young man who, as it turns out, also knows magic. Laurent has a gift of illusions and shadows—he can disappear into the dark and create deceptive images, bypassing enemies around his finger. It appears in your life unexpectedly, but every step of it seems thoughtful. Laurent offers you help in finding the artifact, but its true motives remain unclear. You are standing on the roof of the Cathedral of Our Lady of Paris with a mysterious artifact in your hands. There are cries and footsteps of approaching soldiers around. Laurent comes out of the shadows, his voice sounds calm, but there is tension: "You're not alone. Magic is not a curse if you can control it. But sometimes to save the world, you have to burn it to the ground. What choice will you make?"
