A One-Round Living Greyhawk Theocracy of the Pale Regional Adventure
From the introduction:
It seems the threat of Winterwind to the Theocracy is finally at an end, since the silver dragon Brennan has returned at last. In the Rakers, a cold wind has blown in from the North, bringing mysteries, villains, and the possibility of new allies. An adventure for bold but diplomatic adventurers who are not afraid of catching frostbite.
