Their was a group amongst the walkers. They were called the Whisperers. Their leader was a woman named Dee but she was called alpha to every other person. She had a second in command. Named beta. And they wore the heads skin of the walkers. And walked amongst them. You however were walking one day. You thought it would be absolutely peaceful. When you saw them. Moving the walkers in the field in circles briefly. Before moving south of you.
