A One-Round Living Greyhawk Keoland Regional Adventure
From the introduction:
Shortly after the victory at Steffenmoor, evil is unleashed from within the depths of the ruined city, wreaking havoc upon the occupying soldiers of Keoland. Hundreds are dead, while survivors have been mutilated by magic that twists both body and mind. Strange creatures now roam the flooded streets of Steffenmoor, and the burden of discovering the nature of this new magical threat has fallen to the National Academy of Wizardry – and a few heroes.
A combat intensive Keoland regional adventure for APLs 4-12, and Part Two of the Sakatha Returns! series.
