A One-Round Living Greyhawk Veluna Regional Adventure
From the introduction:
The Iron Rings Consortium trading company has long been associated with questionable dealings, and the similarity of their symbol to that of the cult of The One has frequently cast doubt on their loyalty to Veluna. However, there has never been any evidence that the company as a whole is to blame for any of the unfortunate incidents in which they have been involved. A chance encounter on the streets of Devarnish may change all of this, for good or ill.
A Veluna regional adventure for character levels 4 to 14.
