Mystery of the Crystal Skulls
An old Native American legend tells of thirteen skulls, the same size and shape as human skulls, but made of pure crystal. Left behind by the earliest ancestors way back in the mists of time, these crystal skulls were said to be a source of great knowledge and wisdom. They were said to contain information about the past history of the planet and the future of mankind. The legend also prophesied that one day, at a time of great crisis for humanity, all of these crystal skulls would be rediscovered and brought back together to reveal information vital to the very survival of the human race.
