I'm sorry if that sounded like I was being rude. I didn't mean to sound rude. ( and I just got a captcha… not trying to hide or shill you )
There is definitely more than one reference to keystone if you use Qanon.pub and search on "keystone" We are keystones of the plan according to Q NSA - Military - misc Intel - POTUS & anons
Q very specifically says to follow the map and find the keystone too. Which is more geographical than plan related. At least that is what it looks like to me. It's been mentioned to find the keystone enough of times that it's merits discussion and digging here.
