Dear Devil Lady,
There is no better place on Earth then the Fertile Crescent! With an outstanding irrigation system from the Tigris and the Euphrates rivers, our agriculture is most abundant and nothing surpasses our civilization. This is home to us. We established our form of writing, known as Cuneiform. Our education has excelled since we have created our writing system. Not only that but our religious beliefs are more advanced than any civilization around and our extensive list of Gods is top notch. What does the Indus River Valley offer us that the Fertile Crescent hasn't already provided our civilization with? We would never consider leaving this place... not for anything!
