Description[]
In 1928 two people, with the partial knowledge and consent of the senior faculty of Miskatonic University, attempt to protect the human race from the horrors of the Cthulhu Mythos. While one instructs the entire library staff in a safety protocol regarding access to the restricted library, the other steals newer documents which they believe to be more dangerous and throws them in the university furnace.
