Hello! @zuerich,
Thank you so much for your support! and yes the 9th cryptic key :)
Hive is a tree and we symbolize the branches of the tree because we have developed as a community, I combined the photo you chose below as the 10th photo, I could have made 10 photos, but I chose to put the tree at the bottom because its branches represent the remaining other 9 rules and expand and grow as those rules are followed. I edited and reposted it, thank you again.
Have a nice day!
