any sort . . . and, by God, you'll go wherever it is your sort of horror goes when it dies."
"Who are you?"
"Never mind, who I am. What's your name?"
"Jared."
"Okay. Do what I tell you, Jared, and you won't be hurt. I don't know how you communicate in this place, but don't try it. If I die, you go with me. Got it?"
"What do you want?"
"Tell me about this . . ." He pointed to the rows of discs. He saw that each bore an embossed hieroglyphic symbol. None of it made any sense. "What do these mean?"
Jared said nothing.
"You heard me. Look . . . I'm getting out of this place—see? And you're helping me. I'm not arguing. What are these discs?"

He released him.
"Earth. Terra. You call it the First Sphere? What disc is for Terra?"
Jared touched one.
"If that's not the right one . . . if you're fooling me!"
"It's the right one. You press twice . . . then to the left. It's what we call First Plane Wave . . ."
"Sound?"
"I don't know what you mean. It carries the Terra vibrations. It sends mind pictures."
He thought: I'll have to chance it. It was a thought within a thought. His mind said: "You'd better be right." He spun Jared around and let his fist smash hard down on the hollow between the shoulder blades, and the elemental fell on the floor, momentarily paralyzed.
He found a sort of silver string and tied the elemental's limbs, and straightened up, panting. His hand went out to the Terra disc, but a thought checked him.
"I must make some sort of prep-
