Long ago we pacified this area for the Emperor. For a time, things went well. The ancestral shrines were kept in good order and the people were content. As years went by Imperial inspectors came less and less, and gradually forgot this land. The governors stopped sending tribute to the court. In 6 Tin Hau (200 Years ago) The emperor sent an army to bring the region in order. All the signs were wrong. When they tried to cross the valley they found the very elements had risen up against them. They died, one by one, and none made it outside of the valley. You must calm both the elemental spirits and the spirits of the fallen soldiers. Only then will Heaven's rule be restored.
In this valley there are 4 pools. Each are haunted by a spirit. Assuage the spirits and the valley will become wholesome once more...
With this the smoke is blown away in the wind...
