System: When activated and struck with the smaller stick, this piece of wood emits a single, short sound. A roll of Wits + Performance, difficulty 6, is required; the number of successes on this roll indicate how loud the sound is (one is a whisper, five very loud). The nature of this sound depends on the type of spirit bound into the fetish, but it always emits a sound from nature -- a twig being broken, the plop of a stone in a river, and the like. Each sound stick emits only one such sound, and is limited in time to less than a second (a bark is permissible, for example, whereas a howl is not). Lupus Ragabash, particularly Red Talons, often employ these fetishes to mislead hunters and the unwary for their own amusement -- or darker purposes.... Another common use of this fetish is for sound effects at a Moot while storytelling. The Glasswalkers are attempting to fashion a similar fetish which emits unnatural sounds, such as single gunshots, but so far have met with no success.
Spirit: Virtually any non-urban spirit can be bound into a Sound Branch, but only one sound related to that spirit will be produced. As always, only one spirit can be bound into a fetish.
