At the beginning of the 13th century, the Mongolian Empire was united by Genghis Khan, whose real name was Temüjin. At his death, he was buried with mystical artifacts, one of which was said to contain a dark and evil power.

Time passes and the tomb remains undisturbed until archaeologists recover the artifacts and place them on display at the Stevenson Museum. Slowly, the powers of the artifacts begin to reawaken.
