From Introduction: "Spider Asylum" is a short adventure for experienced characters for the Swing roleplaying game. The characters come to the Spider Penitentiary to explore a possible spiritual site and discover the Federal prison overrun not by the inmates, but by crazed guards and possessed staff. The characters quickly learn not only of an unorthodox experiment, but of a history of spiritual influence on Spider Penitentiary itself. The adventure takes place in the desert of New Mexico, which has a WILL Rating of 2. The Penitentiary itself, which discourages a connection with the spirit, raises the WILL Rating to 6 or so. However, for the sake of this adventure, the default WILL Rating is 2.
