"It is an infinite plane divided into two sections by an infinite straight cliff. Newcomers who are judged very unlikely to make trouble for one another are sent to the upper half, everyone else to the lower. Every person is supplied with a residence, where new instantiations of destroyed objects periodically appear. I am pleased with the residential and transit systems, and with the rule I formulated to prevent dust from accumulating on surfaces. My domain has existed for a very long time and there would be a considerable amount of dust if it were allowed to accumulate."
