A one-Round D&D LIVING GREYHAWK®
Iuz’s Border States Metaregional Adventure
A simple escort mission has brought you to the spur of Rift Canyon known as Dragon Rift. What could make its master worried enough to employ common humanoids to do his work? An Iuz’s Border States metaregional adventure set in the Combination of Free Lords, for APLs 6 to 12. Having a wilderness oriented PC at the table will prove beneficial during this adventure. PCs that have the Enmity of Morginstaler will find this adventure to be very bad for their health.
This is Part One of the Seeker of the Flesh series.
