While working in the Amazon basin a young man, John Sullivan Brooks, fresh out of college, arrived with dreams of finding lost cities, Mayan temples, and old civilizations. At first, he bought into the many stories and ideas, and he had plenty of people willing to sell their secrets, maps and directions to this eager young man. All he ever found were old myths, other people's dreams, and rocks, lots of rocks, so he gave up on those ideas.

Twenty years later, still working deep in the Brazilian jungle, Brooks accidently stumbled on a secret legend hidden for thousands of years: An ancient people still alive, living deep in the Amazon. They had started their travel here from the frozen north twelve thousand years before. These were the people of the Great Blue Ice Wall. They had migrated here over time from a land cold and harsh, covered with glaciers.

Their many stories and oral history told of an ancient time when humans feared man's only natural predator, a prehistoric beast that even today creates, deep in us, a natural fear of the dark. This Legend of the Jerawoc and this hidden city were well hidden behind real native fears of death to anyone who spoke of them.

The legend was real, and this changed everything. Brook's challenge now was to protect these ancient people and their history from modern man's greed.
