A One-Round Living Greyhawk Veluna Regional Adventure
From the introduction:
Three rings forged from fire and metal unknown. Three rings that have stumped scholars for over a year as to what their true purpose is. One ring in the hands of the 'One' while two rings are held in two cities kept hidden away from even the most devout. Locked deep away with the Vale's best guarding them while Veluna's citizens go about their day... then it turns into night and the two rings begin the call...
For [character levels] 6 - 14.
