From time immemorial, a special category of people lived in our world. Some were barely noticeable, and were not much different from you and me - ordinary people. Maybe this is a feature of their soul, or maybe the structure of their brain cells. Or maybe both. For many centuries they have enriched our world, creating a unique atmosphere. The disappearances began in a northern country, where one day the rules of behavior began to prevail over common sense, and the descriptions of science fiction writers became a reality. Many such people - unique and different - were forced to put on carnival masks, put on invisibility cloaks, and even disappear. Now they live in captivity and according to someone else's rules. They feel constant pressure from society and lack of acceptance from those around them, who, unfortunately, have surpassed them in quantity, but not in quality.
