Long ago in the old Stone Age, a young hunter left his clan's camp in the mountains to hunt alone. While he was gone, a major earthquake hit the area. The frightened hunter headed back to ask his elders what had happened and what it meant, but when he returned his clan was gone. This was a disaster, and to make it worse his people believed that without a clan you could not be human.

Then began a quest by this one lone hunter to find humanity—and the humanity he was hunting was his own.
