devils do that all the time? Plain cold-blooded murder?" Zeeth nodded. "They have no emotions, you see. They are what you call hedonists. And they are gods. We are like animals to them. The moment we make a mistake, or are no longer useful, we are killed." "And you submit to it!" "There was a rebellion two years ago, I heard. Twenty slaves died to every Swamja. They are like reptiles—nearly invulnerable. And we have no weapons, of course." "Can't you get any?" "No. Nor would I try. Venusians cannot endure pain, you understand.

Day and night without pause the virus is blown upward through that tube, far into the air, where it is carried all over the planet." The air was darkening, thickening. Here and there rainbow lights sprang into view. Elfin fires in an enchanted world, Vanning thought. Through
