QUOTE : There are many worlds. Yet we constantly separate ourselves, by degrees, from the others. We create arbitrary distinctions to set ourselves apart. But let me speak first of the two main worlds that orbit each other. There are those who live in estates and cities that have mastered the clouds and sit on their perch of air to overlook the vast landscapes below. That is the upper world. The world of the wealthy. The world of the gifted. The world where the Mysteries hold sway. The other world is darker. There are neighborhoods of extreme poverty. Winding alleys and street urchins and gangs. This is a world of fog. It is a world of coughing, sickness, and pestilence. It is a world where industry beckons the ambitious to risk their all—and where the mighty and rich descend in shame after their fortunes have been ruined by games of chance and power. These are very different worlds. And yet, they are much the same.
