As an interesting side note, the SPhrinx and the Great Pyramids are closed today. The Egyptians had one too many groups that wanted to perform 'mystical ceremonies' due to the mathematical importance of 11/11/11 and just shut everything down to keep 'em away.
Free 'historical plot thread' for somebody to pick up and run with for Shadowrun. (Yeah, sixty years ago, right before magic came back, these guys did this thing at the Pyramid. But I have new data... let me show you...)
