A One-Round Living Greyhawk Veluna Regional Adventure
From the introduction:
The Festival of Crowfest is here and the streets of Valkurl are packed. Merchants from all over Veluna cram the streets as farmers sing praises to Beory and Merikka for a bountiful season. Wealth and goodwill are all around you but something dark lurks in the cracks. Someone is not what they seem but can the party find out who in time to save the town and themselves?
