Not sure if anyone’s explored this, or not. KRYPTOS is the sculpture outside of Langley that contains one of the most famous unsolved puzzles in the world.
Q has consistently told us that there’s a keystone to unlock everything that’s been posted. Within several layers of the KRYPTOS cypher are the same words ‘Key, Keyhole, Keystone’ etc. Is it possible that KRYPTOS itself contains the ‘keystone’, the cypher wheel, that unlocks Q’s map?
