You live between the cracks of the city, surviving by thieving, begging, whoring or whatever will get the coin for food and shelter. You are invisible, you are legion, and you may be the last chance the city has.
The city is under siege, and as panic grows and food runs short, the rest of the people are being pulled down into your world. This could be your hour come at last, a chance to rise again, a chance to be a hero, or a chance to destroy a world which has treated you terribly. All you need to do is seize it and choose.
