"A century of days has passed since I saw this area last. The diseased ones sought to kill poor Red, but I took them on a wild poultry chase, they ended dead. They came from out the big metal door but after all my years I knew the caves more. Hide and seek turned to seek and hide, and I buried them here beneath the solid rock sky."
