From the back of the adventure:
"For nearly a millennia, the half ruined hilltop Keep known as the Temple of Kubla Khan has loomed over the surrounding. Built by the Dwarven prophet, St. Canor, the ancient temple served to bind a horrid beast of chaos and evil in eternal imprisonment. For deep beneath the hallowed temple walls lie the chambers of the Crawling Queen, a creature of nightmare and dread chaos. St. Canor battled her of old and bound her through the magic of three Ward Stones. Many years have passed, from that day to this... and not all the ancient magics binding her are remembered or even working
Plunge into the Depths!
In dark, dank hallways and twisted corridors lie the secrets of the past. Plunge into that black pitch of evil to battle a host of creatures and strive to keep the binding upon the Crawling Queen. But strange things lie in the deeps of the world, forgotten magic and unheard of monsters. It is your time now, to answer the call to the ruins of the ancient Keep, to defeat a plethora of converging evils and save the world from doom.
