The great epic of the world beneath the bloody sun known as Darkover did not begin with the coming of the Terrans. It began far earlier, during the dark days of the civilization that came to be know as the Ages of Chaos. For in those years the power of the matrix was first learned and misused in a power struggle between the rising Domains. That mental-physical force created a technology that threatened to make Darkover into a frightening duplicate of all that was bad in far-off Terra.
