from the introduction: Spirits -n- Spurs adds the supernatural to your S-n-S game if you like a little weird with your west! The material presented here takes place in mythical Davestown Texas (but feel free to use your own town). The characters take the role of members of a secret society like group called The Shadow Posse. The characters wield 5 mystical relics that help them to fight the supernatural “creatures of the shadows” that plague the town. Thing is nobody else in town knows anything about these creatures and the Shadow Posse has to work in secret, or everyone will think they are crazy!
