after a time kt-7 sat down on a crushed bulkhead and looked out over the vast field of jagged metal and broken rock , she saw only small creatures darting in and out of hiding , each one searching for some scrap of food that might sustain them for another day , the young girl watched them for a time then slowly rose to her feet , she took off her helmet and wiped her eyes with the back of her hand , then she pulled the headgear over her hair and was about to turn away when she heard a faint beeping sound .
