A One-Round Living Greyhawk Ket Regional Adventure

Borders come and borders go but nomads still roam the Plains of the Paynim south of Ket, sometimes venturing into the Tusman Hills themselves. Do you dare to brave an area claimed by the tribes and see what you can find out about their future or their past...
An adventure for the fleet of foot and stout of heart from [characters level] 2 - 12.
