As a member of the Bridgwater Preservation Society, you and your friends investigate the stories people plague the city and area with. The stories the police won't investigate, or quit on, way too easily. Living next to the Hockomock, at the heart of what will later become known as the Bridgewater Triangle, gives you easy access to delve into any of the stories that arise.
The Hockomock Swamp, named the Devil's Swamp by the original English settlers, is a known site for paranormal activity. Everything from Bigfoot, aliens, thunder birds, huge snakes, strange lights, Puckwudgies, Native American curses, cultists, mutilated animals and more have been reported in the area. So join me and my team as we help unravel the Mythos tied to the mysteries of the Hockomock.
