The Palace of Plenty
The fair Yayosei were the children of an ancient tribe of benign river spirits, until they tried to preserve their paradise by trapping the power of the Void Dragon. Their home was indeed preserved, but at a terrible cost. Today, the descendants of the Yayosei have degenerated into beasts, but what remains trapped within the Palace of Plenty is much worse. An Oriental Adventures scenario for 10th-level characters.
