Most cities lived on the very edge of civilization. Everyone talked about towns and villages out in the middle of nowhere as if they were uncivilized, but she’d found people in those places pleasant, even-tempered, and comfortable with their quieter way of life. Not in cities. Cities balanced on the edge of sustainability, always one step from starvation. When you pressed so many people together, their cultures, ideas, and stenches rubbed off on one another. The result wasn’t civilization. It was contained chaos, pressurized, bottled up so it couldn’t escape.
