Earth

The world ended. It is no longer remembered what caused it. Some say war and some say natural disasters but no one knows for certain. The countries are now nonexistent and are no longer governed by a central power. The land is covered in ruins of old from about 1,000 years ago. Places are covered in vegetation or are massive deserts. Humans are now a fraction of what they once were and live either in the wilderness in tribes or in towns. Some areas have a few cities ruled by someone but most are single towns with single or group leaders.
