"On the day the world ended," "The faith of mankind was carried in a small metal box." "In a secret location." "Architects, scientists and engineers met and concluded that there was only one hope for our future." "To build an underground city." "Designed to keep its citizens protected" "For generations to come." "Secure the box." "Set it for 200 years." "Will keep them in the city for 200 years." "You're certain it won't be long." "None of us can be certain of anything." "We can hope." "Growing up with no knowledge of the world outside." "Future generations will be spared sorrow." "What they've lost." "For the good of all mankind" "The box was entrusted to the first mayor." "Who was to pass it on to her successor." "As the years counted down the box passed from mayor to mayor." "None knew what secrets it held." "Only that it would open when it was needed most." "But fate run another course." "And the chain was broken." "The box was tucked away and forgotten." "And as the city grew old and begun to crumble," "The box quietly lid opened." "Hey, Dad hear that?" "Hurry up. don't wanna be late" "I am hurrying."
