In the 370th year of the Ash Era, the black curtain of eternal night shrouding the North is getting thinner and thinner, and ancient evil things are beginning to move in the shadows. Kyle is the youngest night watchman in Silver City. His duty is to patrol the city walls, light the silver fire to ward off evil spirits, and be alert to the whispers in the dark. However, what really troubled him was not the monster outside the city, but the precognitive dream that dragged him into scenes of endless blood and destruction every night, and the wound on his palm that had been burning and bleeding with strange golden light since the coming-of-age ceremony. He viewed it as a curse and tried to hide it.
Until that moonless night, he clearly saw in his dream that Yinhui City was reduced to ruins in the monstrous green evil flames, and the source of everything actually pointed to the long-forgotten statue of the first king in the dungeon. At the same time, a mysterious visitor claiming to be from the "Amber Society" appeared under the city gate carrying a broken amber pendant that was exactly the same as Kyle's dream, and named the "Night Watchman with a Golden Palm". Kyle is forced to face his destiny. A thorny journey related to the survival of the kingdom, dusty history and lost artifacts slowly begins as the crown made of amber and starlight from the beginning of the world is re-remembered deep in the dungeon. He must find the scattered pieces of the crown before the eternal night completely fades and the evil eye opens again.
