The universe did not oppose-it simply did not care. As his desired outcome was but one of an infinite number of possible outcomes, and could be secured only through immense and long-term effort, any small miscalculation or misstep or unforeseen interference could cause the “unlucky” circumstances which, if not immediately and efficiently corrected, could lead to failure.

Daneel did not hold this view as a philosophy. Both Lodovik and Daneel, like all high-level robots, had been programmed to accept such things without thought. Emotions of a sort-the basic thinking patterns of social beings-were familiar to these robots, and even had their analogs in various combinations of heuristics, but these analogues did not often loom large in a robot’s conscious awareness, any more than its realistic view of existence. Robots were not usually prone to introspection and to examining the roots of their conscious existence; everything referred back to their basic programs, unassailable givens, and those programs referred back to the Three Laws.

Lodovik no longer had such constraints. He watched Eos grow larger, its solid oceans of water-ice and methane and planes of ammonia-rich mud shading the illuminated landscape. He was introspective. He turned his head to look at Daneel, and wondered what he was thinking.

There were only two possible reasons for a robot to attempt to model the inner processes of another robot: to anticipate that robot’s actions, and attempt to coordinate with those actions, sharing duty, or to find some way to foil those actions. Lodovik was totally unfamiliar with the second reason, yet that was what he hoped to do.

Somehow, he knew he had to get away from Eos without being “repaired,” and to find the other robots who opposed Daneel, the so-called Calvinians.

“This ship will dock in twenty-one minutes,” the autopilot informed them, treating them as if they were human passengers.

So far as it was able to judge, in its specialized way, they were; it knew no other kind of passenger. Yet no passengers other than robots had traveled on this ship for thousands of years. No human had ever been to Eos.

Somehow, Lodovik felt like an intruding and betraying-what? He labored to think of an appropriate human word. A ghost, perhaps, malignant and deranged, masquerading in the body of a robot…

The ship rotated slowly and the moon passed out of view. There was only the broad thick spill of the nearest dense spiral arm, viewed almost edge-on and quite faint from this vantage, near the diffuse rim of the Galaxy. Above and below this faint mottled band, filling over a third of their field of view, stretched a profound blackness very thinly scattered with lone points of light, a few stars close and within the Galactic plane, other stars far away and high above the plane. Still others, much farther away and even dimmer, were not stars but galaxies.

Eos’s surface came back into view, much closer and rich with detail. A few craters threw splashes of ice dust across the oceans and plains; for the most part, however, Eos’ solid hydrosphere was unmarked but for the signs of internal disruption: tortuous seams, heaves, the puckered chasms and pressure ridges. This star system had no marauding belts of asteroids and comets, subject to perturbation and gliding silently inward to disrupt the moons and planets.

Eos was isolated and ignored, solid, cold, inhospitable for any living thing-and for robots, almost completely safe.

“We have docked,” announced the autopilot.

Had anyone looked, the station pioneered and built by R. Daneel Olivaw and R. Yan Kansarv would have been clearly visible against Eos’s frozen surface, even from millions of kilometers in space. Its heat made it the most brilliant object on the moon-for those seeking infrared signatures. None did, or ever had, however.

Lodovik and Daneel disembarked from the transport in a broad and almost empty hangar, with room for many ships. Their footsteps echoed in the cavernous enclosure. Lodovik had been here almost eighty times before, yet had never thought to be curious about this anomaly. Why had Daneel and Kansarv wasted so much space? Had there ever been occasion when this hangar was filled with ships-filled with robots? When had that been?

Yan Kansarv itself met them a hundred meters from the transport. It stood with “arms” crossed and “fingers” linked, a gleaming dark steel head and body highlighted by brilliant silver limbs-four arms, two large and emerging from where human shoulders would have been, two small and recessed into its thorax; and three legs, on which it walked with a precise and level grace unknown to humaniform robots. Its head was small, equipped with seven vertical sensor bands, two of which glowed blue at any given time.

“It is a pleasure to see you again, Lodovik Trema,” Yan said in a rich, slightly buzzing contralto. “And Daneel. You are very late for a maintenance check and refit.”

“We must work quickly,” Daneel said, eliminating any human signs of greeting. Yan immediately switched to robot microwave speech. The following detailed explanation took less than half a second.

Yan then turned to Lodovik. “Pardon my eccentricities,” it spoke, “but whenever possible it gives me pleasure to exercise my human functions. I have been unable to do so for over thirty years. Except, of course, with Dors Venabili. I fear, however, that she no longer finds me of interest.”

Daneel had already inquired about Dors’ progress, and had received an answer. Yan, however, explained in speech once more to Lodovik. “She has made a very satisfying recovery, but with many lapses. When R. Daneel brought her here, she was close to total breakdown. She had stretched any interpretation of the Zeroth Law to the very limits by destroying a human who threatened Hari Seldon. The strain was compounded by the effects of her victim’s invention, an Electro-Clarifier, I believe it was called…”

Lodovik realized that this ancient robot, built many thousands of years ago to repair other robots on Aurora-and the last of its kind still functional-was reacting deep in its programming to their convincing human forms. It knew, on one level, that they were fellow robots-but on another level, a primal and irresistible urge arose to treat them as if they were human.

Yan Kansarv was lonely for its ancient masters.

“She awaits your company,” Kansarv said, then, to Daneel, it added, “She wishes news of Hari.”

“That mission is finished for her,” Daneel said. “She was constructed by me, using ancient plans for convincing helpmeets and consorts, to be as nearly human as any robot ever made,” Kansarv reminded him. “More even than you, R. Daneel. She bears a great resemblance to R. Lodovik in that regard. To alter that now would be to destroy her.”

“There is so much work to do,” Daneel said, with a faint intonation of urgency.

Kansarv was not oblivious to this. “I can perform all the necessary tasks within twenty-one hours, then you may leave. I hope there is time for more conversation. I need outside stimulus now and then, or I become subject to minor malfunctions that are irritating.”

“We cannot afford to lose you,” Daneel said.

“No,” Kansarv agreed without a hint of self-pity. “The only robot I cannot repair or manufacture is one like myself.”

Dors Venabili stood in the simple four-room enclosure built for her upon her arrival on Eos. The furniture and decor was similar to what might have been found on Trantor, in the quarters of a mid-level meritocrat or high-level university professor. The temperature was set at just above the freezing point of water; the humidity was less than two percent, and the light level was what a human would have regarded as murky, sub-twilight. These were optimal for a robot, even a humaniform, with the added benefit of reducing her energy use to a minimum.
