But now the mri have faced an enemy unlike any other - an enemy whose only way of war is widespread destruction. These "humans" are mass fighters, creatures of the herd, and the mri have been slaughtered like animals.Now, in the aftermath of war, the mri face extinction. It will be up to three individuals to save whatever remains of this devastated race: a warrior - one of the last survivors of his kind; a priestess of this honorable people; and a lone human - a man sworn to aid the enemy of his own kind. Can they retrace the galaxy-wide path of this nomadic race back through millennia to reclaim the ancient world which first gave them life?
