This is an emergency protocol. Icons weren’t ever going to stay friendly or human forever. They just turn into haye themselves on a certain threshold with man and then start destroying him or her. So they have to be rendered or evaded all the time. They reach proximity range and create a radius of predation naturally with man. It’s a daily hunt for them after the friendly part is over, or once they’ve created their radius around man. Captivation and submission to an icon follows and man dies.
