World of Darkness  is a dark, gothic-punk reflection of our own world. 

It's still Earth, with the same countries, the same people in power, a Starbucks on every corner. However, it is nonetheless a worse place: people care a little less, the boot on your neck grinds a little deeper. Gargoyles peer down uncaringly from nearly every edifice, even as the skeletal fingers of those skyscrapers stretch further into the heavens. 

Despite this, or perhaps because of it, you fight back. The systems of power are unfair. Hell, the world itself is unfair. So you fight back. Because you can. Because you have no other choice, if you want to survive.
