The Supernatural Studies Association is an organization dedicated to exploring haunted locations across the United States and debunking or proving the existence of supernatural beings. Greg Mac Lochlainn, Lisa Bertsch, and Jake Smith are the only known members who still work for the association.
Jake Smith is the rookie intern for the team as Greg explains on the Night 1 phone call. Henry was an intern for this group before Jake Smith, but he later disappeared in Pirate Caverns after wandering off without Lisa's supervision, eventually resulting in his death and reanimation as a yellow-blood-covered zombie.
