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. To us, pain is worse than death."

Vanning grunted, and was silent as they passed through a curtained arch. Never would he forget his first sight of the Swamja city. It was like—

Like an ocean world!

He stood upon a balcony high over the city, and looked out at a vast valley three miles in diameter, scooped out of the heart of the mountains as though by a cosmic cup. Overhead was no sky. A shell of transparent substance made a ceiling above the city, a tremendous dome that couched on the mountain peaks all around.

Gray-green light filtered through it. An emerald twilight hazed the fantastic city, where twisted buildings like grottos of coral rose in strange patterns. It was a labyrinth. And it was—lovely beyond all imagination.

"Those—things—built this?" Vanning breathed.
