The fantasies pertain to a castle in Lowell atop a muted green hill that Jackie calls Snake Hill. Underneath the misty grey castle, the Great World Snake sleeps. Various vampires, monsters, gnomes, werewolves, and dark magicians from all over the world gather to the mansion with the intention of awakening the Snake so that it will devour the entire world (although a small minority of them, derisively called "Dovists," believe that the Snake is merely "a husk of doves," and when it awakens it will burst open, releasing thousands of lace white doves. This myth is also present in a story told by Kerouac's character, Sal Paradise, in "On the Road").
