The city of the rich,the poor and the not-so-good

Imagine the future for a second. You then imagine yourself in a big bright city. Soaring across overhead of your head are flying cars, shiny and tidy as if the word unclean never existed. Then you vision the giant towers and buildings around you, with their bright lights. You see people laughing, enjoying their lives as a family. Then something dark approaches, you first think it's just a storm but it suddenly approaches absorbing everything as if it were a living thing. The family screams, the buildings fall,cars are destroyed. The Dream is crushed,reality is suddenly a dystopia,everything is under the control of the darkness. This will happen if they fail.
