The Stalkyard (2007)

A One-Round Living Greyhawk Keoland Regional Adventure

From the introduction:

As an unusually hot Keoish summer fades into autumn, events on the western border of the Empire continue to smolder. The truth is now filtering to the ears of Keoish citizens: war has come to the western marches and with every passing day marches eastward to Niole Dra. As the Keoish Empire reels from this sudden onslaught, a bold counterattack is planned on the heart of the assaulting forces: Godakin Keep. But is the assault a diversion, a suicide mission, or a stroke of genius? Only time will tell, because only the survivors author the histories.

A Keoland regional adventure for APLs 8-12, and Part Four of the To the Last Man Standing series.
