To Kendy, who thought with the speed of a computer, the “Scientist” moved much too slowly. Now he was at the controls, auditing a cassette; now checking the camera views in present time…

The incoming CARM records showed clouds and ponds and trees and trilaterally symmetric fishlike birds swirling across the sky. Natives flickered through the CARM cabin: the same savages, growing older; a growing handful of children.

At fifteen years minus-time the CARM backed out of its timber dock for a journey of exploration. It visited a green puffball several kilometers across, and when it emerged there was vegetation like a houseful of green spaghetti bound to its dorsal surface. It hovered in the open sky while men darted among a flock of birds — real birds with real wings: turkeys — and returned to its dock with prisoners.

At thirteen years minus-time it left the trunk to return with a dubious prize: several tons of black mud.

There were no more such forays. The Cargo and Repair Module had become a motor for the tree.

It was docked when the main drive fired for several hours. Kendy watched side views as the integral tree drifted across the sky. It had been circling too far from the neutron star. Air grew thin away from the Smoke Ring median.

The tree was lower now; the air would be as thick as mountain air on Earth. And now the CARM was not being used at all; but there was plenty to watch. The Smoke Ring environment was fascinating. Huge spheres of water, storms, jungles like tremendous puffs of green cotton candy.

In present time, the aft CARM camera showed nearly thirty natives maneuvering between the tree and a tremendous globule of water. They were using the free-fall environment better than any State astronaut. The State had need of these people!

Discipline’s own telescope had found the foreshortened tree, with the pond to mark it. And what was that on the opposite side of the tree? Infrared light glowed near its center…

Half a thousand years of sensory deprivation were being compensated in a few minutes. After more than five hundred years, Sharls Kendy had left the stable point behind Goldblatt’s World. He had burned irreplaceable fuel, and it was worth it! Sharls tried to absorb it all, integrate it all…but that could wait. The “Scientist” might leave at any minute!

He beamed: “Interrupt records.” It was twenty Earth years of nothing happening, and the tiny CARM autopilot couldn’t handle too many tasks at once. “Activate voice.”

“Voice on.” The .04 second delay was almost too short to notice.

“Send—” He displayed a picture of himself as a human being, with minor improvements. At age forty-two Kendy had been handsome, healthy, mature, firm of jaw, authoritative: a recruitment-poster version of a State checker.

These were not obedient State citizens. They hadn’t trusted him twenty years ago. What words might give him a handle on Jeffer the “Scientist”?

He sent, “Kendy for the State. Jeffer the Scientist, your citizens have been idle too long.”

Jeffer jumped like a thief caught in the act. Two long seconds passed before he found his voice. “Checker?”

“Speaking. How stands your tribe?”

Out beyond the terrible whorl of storm that surrounded Gold, out where water boiled and froze at the same time and the legendary stars were a visible truth, lived Kendy the Checker. He had claimed to be something like an elaborate cassette: the recording of a man. He had claimed authority over every human being in the Smoke Ring. He had offered knowledge and power, while they were still near enough to hear his ravings.

Perhaps he was only a madman trapped somehow aboard the spacecraft that had brought men from the stars. But he had knowledge. He had coached them through that terrible fall back into the Smoke Ring, fourteen years ago.

The face in the CARM’s window had not been seen since. It was the face of a dwarf, a brutal throwback. The jaw and orbital ridges were more massive even than Mark’s, the musculature more prominent.

“We lived through the reentry,” Jeffer told him. “Ilsa and Merril are dead now. There are children.”

“Jeffer, your tribe has possessed the CARM for fourteen of your years. In that time you have moved the tree twice and thenceforth done nothing at all. What have you learned of the people of the fourth Lagrange point?”

The what? “I don’t understand the question.”

“Sixty degrees ahead of Goldblatt’s World on the arc of the Smoke Ring and sixty degrees behind are regions where matter grows dense. They are points of stability in Goldblatt’s World’s orbit. Material tends to collect there.” The dwarf’s brutal features registered impatience. “East of you by twelve hundred kilometers, a vast, sluggish, permanent storm.”

“The Clump? You’re saying there are people in the Clump?”

“I sense activity there. A civilization is growing twelve hundred kilometers from where your tree has floated for fifteen Earth years. Jeffer, where is your curiosity? Has it been bred out of you?”

“What do you want from me, Checker?”

Kendy said, “I can be in range to advise you every ten hours and eight minutes, once every two of your days. I want to know more of the people of the Smoke Ring. In particular, I want to know about you and about the Clump civilization. I think you should link with them, perhaps rule them.”

Jeffer’s one previous experience indicated that Kendy was harmless. For good or ill, he could only talk. Jeffer gathered his courage and said, “Kendy, the tales say that you abandoned us here, long ago. Now I expect you’re bored and—”

“I am.”

“And you want to talk to someone. You also claim authority 1 won’t grant you. Why should I listen?”

“Are you aware that you are being invaded?”

“What?”

The face ofKendy was suddenly replaced by a dizzying view. Jeffer looked into a river of storm, streaming faster as the eye moved inward toward a tiny, brilliant violet pinpoint. Jeffer had seen this once before: the Smoke Ring seen from outside.

Before he could remember to breathe, the view jumped. He was looking at what had been the center of the picture, vastly enlarged.

“Look.” Scarlet arrowheads appeared, pointing — “Here, your tree.”

“Citizens Tree, from the out tuft? Yeah, and that must be the pond.” Both were tiny. Opposite the pond was… another tree? And dark cloud clinging to the trunk?

The view jumped again. Through the blur and flicker in the illusion of a window, Jeffer watched a tree on fire.

Moving between the two trees were creatures he had never seen before.

“Treefodder! Everybody’s on the other side of the trunk. Those bird-things will be on the tree before anyone knows it.”

“Look in infrared.” The picture changed again, to red blobs on black. Jeffer couldn’t tell what he was looking at. The scarlet arrowhead pointed again. “You are seeing heat. This is fire in the intruder tree. Here, these five points are just the temperature of a man.”

Jeffer shook his head. “It doesn’t mean anything.”

The enlarged picture returned…and suddenly those tiny “creatures” jumped into perspective. “Winged men!”

“I would have called those enlarged swimming fins rather than wings. Never mind. Have you ever heard tales of winged men?”

“No. There’s nothing in the cassettes either. I’ve got to do something about this. Prikazyvat Voice off.” Jeffer made for the airlock without waiting to see the face fade.

His citizens wouldn’t have a chance against winged warriors!

The sun was at three o’clock: dead east, just above where the Smoke Ring began to take definite shape.

Kendy can only talk, sure, but he talks with pictures, and he tells things nobody can know. He’ll be in range every other day at this time. Do I want to know that? But Jeffer had other concerns, and the rest of that thought lay curled unfinished in the bottom of his mind.
