@finnian I don't think there were many secrets in this particular location. The library is open to the public for research so anyone can go in and research the group. My impression is that it's a pretty mundane fraternity with less than ambitious goals. I liked the rules against outside politics and religiousity however. The only requirement to join is to have a belief in a "higher power". The internet has really democratized the formation of these sorts of groups in a way that must have been unimaginable to the Freemasons of old. Thank you for reading!
