In the southern part of the Mainland, a large river that spanned several kilometers wide flowed into the sea, forming a huge delta from the accumulated silt and sand.
The Delta was fertile, with lush vegetation, and the river was rich in nutrients, fattening up a large number of fish.
A large primitive tribe with a population of over 150,000 lived on the eastern side of the Delta at the river's estuary, sustaining the entire tribe with an abundance of food. Especially with the new Totem Church's teaching on fish farming and finding suitable plants for cultivation greatly increased the food production, the tribe had annexed some smaller tribes over the past few years, significantly strengthening their power.
