Nobody knows what strange force partitioned space into these "regions of thought," but when the warring Straumli realm use an ancient Transcendent artifact as a weapon, they unwittingly unleash an awesome power that destroys thousands of worlds and enslaves all natural and artificial intelligence.Fleeing the threat, a family of scientists, including two children, are taken captive by the Tines, an alien race with a harsh medieval culture, and used as pawns in a ruthless power struggle.
