This might be old news to people, but I was just watching this vid (https://www.youtube.com/watch?v=FkGbu-1odI8) and at this part at 12:38 talks about the arch of the freemason compass, and how it's called "THE KEYSTONE", and I just remembered how Q said "what is the keystone" and "find the keystone" a bunch of times. So, there's that, if anyone wants to look into it more!
