A One-Round Living Greyhawk Highfolk Regional Adventure
From the introduction:
The Wyvern's Sting, a bandit group marauding about the Fairdells, has planned a grant heist - one that will surely spell the ruin of a well-respected gnome miner. You are all that stands between the bandits and their goal. Your trip will take you through the Highvale and into the treacherous Clatspurs during the beginning of winter.
