All spiritual energy in heaven and earth came from the Heavenspan River basin. Considering how far away they currently were in the Wildlands, there was no spiritual energy at all in the area.
It was this simple fact that forced Wildlanders to change their fundamental nature and resort to soul medicine to practice their cultivation. It was only because of the endless supply of vengeful souls around them that they could do without spiritual power. But nothing was absolute!
There were some things in the world that, at least in small measure, could produce spiritual energy similar to that found in the Heavenspan River basin. This spiritjade statue was just such an item.
