For hundreds of years people lived on this planet in kinship communities and practiced subsistence farming. Each tribe collectively grew primitive crops, grazed small cattle, and mined useful minerals for their own needs, which were very modest—because the valleys were in the late Iron Age.

But one day, the carefully crafted way of life was broken.
