would no longer be needed except as a subject race. They would be enslaved. "We would have laid the groundwork for an empire—the Varn Empire." There was a silence, in which his words hung like something cold and invisible between them. Then the Varn asked, very quietly: "Why is the Plan failing?" "You already know," he said. "Because of the barrier—the communication barrier that causes aliens to misunderstand the intentions of Exploration men and fear them." "There is no communication barrier between you and I—yet you fear me and are going to kill me." "I have to kill you. You represent a danger to my race." "Isn't that the same reason why aliens kill Exploration men?" He did not answer and its thought came, quickly, "How does an Exploration man appear to the natives of alien worlds?" How did he appear?... He landed on their world in a ship that could smash it into oblivion; he stepped out of his ship carrying weapons that could level a city; he represented irresistible power for destruction and he trusted no one and nothing. And in return he hoped to find welcome and friendship and co-operation.... "There," the Varn said, "is your true barrier—your own distrust and suspicion. You, yourselves, create it on each new world. Now you are going to erect it between my race and yours by killing me and advising the Exploration Board to quarantine my world and never let another ship land there." Again there was a silence as he thought of what the Varn had said and of what it had said earlier: "We are a very old race...." There was wisdom in the Varn's analysis of the cause of the Plan's failure and with the Varn to vanquish the communication stalemate, the new approach could be tried. They could go a long way together, men and Varn, a long, long way.... Or they could create the Varn Empire ... and how could he know which it would be? How could anyone know—except the telepathic Varn?
