“Death in your eyes, Earthman. Nothing in your mind but murder. Can that brain of yours comprehend nothing but battle? Is there no curiosity there? Have you no wonder of why I brought you here? Death awaits you, yes. But a not unpleasant death, and it awaits all, in one form or another. Listen, let me tell you—I have reason for desiring to break through that animal shell of self-defense that seals in your mind. Let me look deeper—if there are depths. Your death will be—useful, and in a way, pleasant. Otherwise—well, the black beasts hunger. And flesh must feed them, as a sweeter drink feeds me...Listen.”
