Visitors to Mendera often thought the wall was a bit of history, a remnant of its early years. In fact the wall marked the extent of Chlo's area of full control.
Within the wall people going to bed with a virus or a cell turning cancerous woke up cured, usually unaware of being cured. No one fell off a high roof, no one except the guards could use weapons, no one was bitten by any wild creature and for the most part sex had no unpleasant consequences.
People still fell in love and formed attachments doomed to failure, but that fell outside Chlo's remit.
