On the edge of Elderton, a town in the Canadian mountains, there is a forest, a forest, that at certain times of the month houses a thing that shouldn't exist. A thing that stalks through the trees looking for prey, prey that eventually it will find in town.
Down the mountainside, in the quiet of the town, the people huddle together. They bar their doors and board their windows, sitting silently and listening. Listening for the howl. The half-human sound dragged from an ill-formed thing, that rings through the town and announces the arrival of the beast. The howl that makes them hope and wish, that it won't be their door, the thing tries next.
