The new era is 1832. The monsters are almost extinct, and the era of the witcher has come to an end. The witcher Hepburn intends to enter retirement life ahead of schedule. The melody of the stars. The old gods, secret associations, shapeless populations from the other side of the galaxy, phantoms in the cracks of time, floating in the world behind the scenes. The dead dragon king wandering on the edge of the underworld, desecrating the exotic realm of physics Life, the magical reflection of Upper Wharton and Lower Wharton. Hewen is trying his best to get his retirement life back on track, and clean up the little bugs he saw on the road.
