The Rise and Fall of the Drude Nfus

There was German folklore about evil nighttime spirits called Drude. The Drude could be warded off with an upside down pentagram, which was called a Drude Nfus. By the time they built it, that symbol began to mean the epiphany in the New Testament. But then later on, people put Satan stuff around the symbol and then they were like, hey, that's weird about this church.
