When Art* told me in our alliance chat that my castle was unshielded, I thought to myself how on earth did Art* know but never I ask how did Art* know. Each time I log in, I try my best to figure out the difference between the two and along the way associating it with bubble or peace agreement use in King's Empire. And finally last night I figured out how. Funny, huh? Oke so try to digest this image. Shield up, alright!
