HOLY SHIT DUDES, HOW DID WE MISS THIS?
So I was relistening to ‘Page Turner’, since I’m trying to put together a better picture of the various human players in the supernatural in the show. Anyway, there’s a throwaway reference to the narrator encountering a 2007 Ebay listing for ‘The Key of Solomon’ 1863, owned by MacGregor Mathers and Jurgen Leitner. And who purchased this book for 1200 pounds? One GRBookworm1818.
The Magnus Institute was established in 1818.
Gertrude fucking Robinson bought herself a Leitner in 2007.
