Valley of the Yellow Stones, ll

There was a valley in the land of the ancients called Sheran and later renamed the Valley of the Yellow Stones. Its name came from the large yellow stones that were discovered in the streams, lakes, and rivers. Back in ancient times, the yellow stones were so plentiful that the ancients made jewelry and gold coins with them to barter with the surrounding villages and towns. They accumulated such a vast amount of riches that their greed overpowered their love for the land and stripped it of its minerals and nutrients; altering the rivers, lakes, and soil; leaving the land barren. Even with all their vast riches, the villagers were slowly and painfully starving to death so the Shaman Gershwen, came up with a plan to give back to the land and end their greediness. Does his plan work?
