A Two-Round Continuous Living Greyhawk Theocracy of the Pale Regional Adventure
From the introduction:
The death of a mighty green dragon meant one less foe for the Theocracy of the Pale. It also meant there was an opportunity for some other creature or tyrant to fill the void left by the dead dragon. Who knows what power or peril could have replaced the dragon? A long trek through the treacherous Rakers at first thaw is the only way to find out.
