A One-Round Living Greyhawk Veluna Regional Adventure
From the introduction:
The Church of Rao has lost one of the rings and an ominous feeling has fallen over Veluna and the church. A bitter, dark winter has yet to let go of its icy grip even though Veluna yearns for spring to come early and bring new life to a distraught country. Unfortunately the darkness seems to follow you, as your presence in Veluna City is not one of goodwill but of mourning as another prominent Bishop has passed. All is not well in the Vale.
