In a society where all information is consumed digitally and history is constantly edited by the governing algorithm, physical paper artifacts are considered contraband. You have inherited a hidden underground bunker containing ten thousand preserved books. A young stranger knocks on the heavy steel door, seeking a specific volume of folklore that has been deleted from the digital archives. Write the opening scene of this encounter, describing the atmosphere of the dusty bunker and the child's reaction to seeing a physical book for the first time.
