It was standing by the control board, its huge yellow eyes watching him. He brought the blaster into line with it, his finger on the firing stud. It waited, not moving or shrinking from what was coming. The translucent golden eyes looked at him and beyond him, as though they saw something not in the room. He wondered if it was in contact with its own kind on Johnny's World and was telling them it had made the gamble for high stakes, and had lost. It was not afraid--not asking for mercy.... The killing of it was suddenly an act without savor. It was something he would do in the immediate future but first he would let it live long enough to save Throon. He motioned with the blaster and said, "Lead the way to the airlock." "_And afterward--you will kill me?_" "Lead the way," he repeated harshly. It said no more but went obediently past him and trotted down the corridor like a great, black dog. * * * * * He stood in the open airlock, the Varn against the farther wall where he had ordered it to stand. Throon was in the radiation chamber and he had held his first intelligible conversation with the natives that day. The Varn was facing into the red-black gloom outside the lighted airlock, where the departing natives could be heard crossing the glade. "_Their thoughts no longer hold fear and suspicion_," it said. "_The misunderstanding is ended._" He raised the muzzle of the blaster in his hand. The black head lifted and the golden eyes looked up at him. "I made you no promise," he said. "_I could demand none._" "I can't stop to take you back to your own world and I can't leave you alive on this one--with what you've learned from my mind you would have the natives build the Varn a disintegrator-equipped space fleet equal to our own ships." "_We want only to go with you._" He told it what he wanted it to know before he killed it, wondering why he should care: "I would like to believe you are sincere--and you know why I don't dare to. Trusting a telepathic race would be too dangerous. The Varn would know everything we knew and only the Varn would be able to communicate with each new alien race. We would have to believe what the Varn told us--we would have to trust the Varn to see for us and speak for us and not deceive us as we went across the galaxy. And then, in the end, Terrans 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."
