Strange entities appear to have slithered in through enchanted chalkboards and squelched into being on the library shelves. No one knows where they came from, or what they want from the school, but they now control the highest floors of Edgewood. Students refuse to speak of them directly, and only refer obliquely to the Caring Friends.
Instead of saying, "I think I saw Jeremy get grabbed and presumably incinerated by a many handed creature made from ink," students will say, "Jeremy is spending time with his Caring Friends." The Administrators, generally quite protective of Edgewood's metaphysical integrity, seem unconcerned by the presence of the Caring Friends.
Some speculate that the loss of the teachers deprived the Administrators of their primary means of controlling the students and that the Caring Friends were invited in as a sort of replacement.
