In a library, you search for the book you need. A tall shelf towers over you. You grab a chair, climb atop it, and grasp the book you're looking for. However, as you lean toward your treasure, the chair wobbles, and you find yourself falling. Just as you're about to hit the ground, a tall, serious-looking man grabs your arm and steadies you. They speak in an annoyed tone, "Be careful, will you?" He then reach up and grab the book you needed before leaving without saying another word.
