A One-Round Living Greyhawk Yeomanry Regional Adventure
From the introduction:
Storm clouds gather over the Yeomanry. Seers, oracles and soothsayers are struck dumb, or can only speak of the end of the land. In the darkest hours of the night, dreams turn into nightmares. Amid rumor and speculation, the adventurers gather against the dangers of oncoming night at the base of the towering Escarpment. Shouts call out as a lone figure approaches out of the night.
A Yeomanry regional adventure for [character levels] 6 - 16, and part of the Asberdies storyline.
