The premise of this novel is the banishment to the seemingly metal-poor planet Treason of a group of people who attempted to create rule by an intellectual elite. The novel centers on the descendants of these anti-democratic thinkers who remain imprisoned on the planet. Through the ages, these descendants have formed nations which warred and allied with one another to gain advantages over their rivals in the race to build a starship. Due to the metal-deficiency on Treason, nations are forced to obtain it through a system of barter using teleportation devices known as Ambassadors.
