Disturbing the Spirits

As a child, Mathias Køhler had always been warned not to go in the woods. He had heard tales of creatures luring humans to their deaths, and had been told on numerous occassions that hiking in the forest at the edge of his village was dangerous. He'd never really bothered to listen to those people, and continued going on his daily hikes, until one day he hears the beautiful sound of a violin coming from a part of the woods off the hiking trail.
