A One-Round Living Greyhawk Veluna Regional Adventure
From the introduction:
An enterprising dwarf has designed a slaughterhouse-tannery in the mountains of Veluna. By selling only the choicest meats, and supplying a grand supply of hides, he hopes to turn his fortune into a title, but his actions are polluting the area, and getting the attention of adventurers. Add to this the fact that his father, an archeologist, has left a sizable skeleton in the closet, and you have an adventure.
An adventure for characters level 3 - 8.
