A One-Round Living Greyhawk Theocracy of the Pale Regional Adventure
From the introduction:
The Troll King has been exposed and the myths of a Lord of Ice are no more; Winterwind lives and claims both titles. The Troll Winter continues unabated and the planting season has come and gone. Starvation is proving a powerful weapon, but out of the past comes an old enemy, bringing hope back to the Pale from a fallen ally.
An adventure for diplomatic [player characters] of levels 2 to 15 who can remember that sometimes the enemy of my enemy is my friend.
Part 4 of Winter Stalks the Pale.
