From the back of the book:
The mysteries of a thousand years lie hidden in the caverns of Sleeping Bear Rock... A lone pinnacle of rock stands high above the deserted hills. Within the haunted tower lies the ages-old crypt of the Sharjani Lords, once known as the Drinkers of Blood. Untold treasures and horrors await the intrepid adventurers that dare enter the halls of the ancient tomb. The portal lies open; can the characters defeat the dark lords within their ancient sepulchre before they rise again to drown the Young Kingdoms in rivers of blood?
