The colony hosted exactly 100 women an equal number divided into two colors. So half the women were blue and half of course were green. Though each knew their own color, blue or green, they were forbidden from sharing their color with anyone else. This sharing was strictly forbidden.
Those hosted also had a favorite fruit they enjoyed. You could see them enjoying their choice fruit daily.
All could remain in this majestic colony forever under one condition. They must be able to identify when called upon, who also among them was ALL KNOWING. Each night one person of color was removed from the colony under the cast of darkness. One night this person was blue and the next night green. This is of course unless she was able to identify ALL KNOWING. If she knew, she was returned to the colony secretly and sworn to total secrecy. This alternate downsizing continued each night and with equal respect to each side. After awhile others noticed and became frightful. As their tribe dwindled they began to whisper among themselves not knowing the color of the other or perhaps speaking in the presence of ALL KNOWING. Before long there became a build of chaos among them, fear, suspicion, back stabbing, hate. And yes their numbers dwindled until at last their was only one.
There she stood at the edge of the colony and ALL KNOWING asked how did you know it was me for sure? She said I studied our collective fruit. I watched how it changed over time as our colony changed. And then I found the one among us who was no respecter of fruit or color. You only wanted our obedience. I knew then I was in the presence of ALL KNOWING. I knew for sure it was you. You never changed.
