She ran. Her footsteps were no longer silent, her breath no longer steady. She sprinted down the corridor, flashlight swinging wildly, illuminating broken signs and warnings in languages she couldn't read. The sound came again, louder, closer. It was following her. Not just stalking, chasing. She could feel it in her bones.
She found another stairwell and scrambled up, barely avoiding a loose step that cracked under her weight. She burst into the main floor, darting through a corridor she hadn't explored yet, and stumbled into a large open chamber. It had once been a control room, panels lined the walls, screens long since dead. In the center was a single chair, facing away from her.
