Lucius had great difficulty with that statement, even presented as it was so calmly after the danger was over. His features lost their clarity, and he had to hold onto the doorjamb for support.
“You would have died. This does not distress you?”
“No more than losing a friend and knowing I could have done something to save her.”
“But…she is not human. Is she?”
“That depends on your definition. But it doesn’t matter. She’s a friend.”
Wolruf looked up, grinned, and looked back to her monitors. Lucius pondered Derec’s statement for a moment, then asked, “Is Mandelbrot your friend as well?”
That had come out of nowhere, but it was easy enough to answer. “Yes, he is,” Derec said. “Why?”
“You risked the lives of everyone on board the ship when you rescued him. You did not know that the engines were safe to use, yet you used them anyway. Did you do that because Mandelbrot was your friend?”
Derec nodded. “Wolruf did the piloting, and she was using the attitude jets, but I would have done the same thing and used the main engines if I had to. And yes, I’d have done it because Mandelbrot is my friend.”
“Even though he is not human.”
“Again, it doesn’t matter.”
Lucius’s features blurred still more, then suddenly returned to normal, or at least to clarity. Under the influence of both Derec’s and Wolruf’s presences, he took on the appearance of a werewolf caught in the act of changing from one form to the other.
He spoke with sudden animation. “Then I believe I have made a fundamental breakthrough in understanding the Laws of Humanics”‘
“What breakthrough is that?”
“If I provisionally regard Wolruf as human, at least in her motivations, then I believe I can state the First Law of Humanics as follows: A human may not harm a friend, or through inaction allow a friend to come to harm.”
Derec was tempted to be flip about it, to say, “That leaves Avery out then, doesn’t it?” but the robot’s sincerity stopped him. And in truth, Avery hadn’t been happy about spacing Wolruf, nor, come to think of it, did Avery even consider Wolruf a friend anyway. Derec doubted if he considered anyone a friend.
He shook his head. “I can’t refute it. It’s as good a guiding principle as any I’ve heard yet.”
Lucius nodded. “If, as you say, friendship can occur between human and robot, then I believe the law applies to robots as well.”
“It probably should,” Derec admitted. In fact, it already must to a certain extent, or the Robot City central computer would never have allowed him to cancel Avery’s order concerning the hunters when Lucius and the others were trying to make their escape. Now that was an interesting development in Avery, s robot society experiment: The robots had independently developed a sense of social responsibility. Lucius had not invented it with his law; he had only discovered its existence.
But that was evidently exciting enough in itself. “I must go tell the others,” Lucius said, then turned and hurried away toward the common area.
Wolruf leaned back in her chair, crossed her arms over her barrel chest, and asked, “Does this mean I ‘ave to make friends with all of them now?”
Derec, watching the retreating werewolf, said, “It probably wouldn’t hurt.”
The landing on Ceremya was smooth, so smooth that Derec didn’t even wake up until well after they were on the ground. He had been spending most of his time asleep, at first to conserve oxygen, but by the second day without a recycler, his motive was more to escape the foul odors building up in the air. And hunger. While asleep he was aware of neither. What woke him now was the sudden fresh smell of plant-scrubbed atmosphere filtering in through the open door.
He gently shook Ariel awake. “We’re there.”
“Mmm?”
“Clean air! Breathe deep.” He rolled out of bed, dressed quickly, and headed for the hatch.
He found Wolruf already outside and Mandelbrot as well. The ship had landed at a spaceport almost identical to the one from which they had taken off nearly a week ago. Derec wouldn’t have been able to tell it from the original save that this one was at the end of a long arm of building-material pavement reaching out from the edge of the city instead of surrounded by it, and the sky here was a subtly different shade than that over the original Robot City.
That wasn’t the way it should have been. The last time he had been here-the only time, before this-the city had been under a dome, a force dome dark as night with a single wedge-shaped slit in it. The Ceremyons had been about to enclose it completely, but Ariel had made an agreement with them to leave the city as it was if Derec stopped its growth and turned the robots into farmers for them. He had done that, but now it looked as if all his changes had been undone. The dome was gone and the city before him was bustling with robots again, and none of them looked like farmers.
“What happened?” he asked softly.
“They left before you awoke,” Mandelbrot said. “I was unable to stop them.”
“Who? What are you talking about?”
“The experimental robots. They are gone. “
“Oh. I wasn’t talking about-gone?”
“Yes.”
“Did they say where they were going?”
“No, they did not.”
Wolruf said, “I came outside just in time to see them all grow wings and fly off that way.” She pointed toward a line of hills in the distance, above which Derec could see a horde of tiny dark specks: the Ceremyons. The dominant lifeforms on the planet were night-black, balloon-shaped things with bat wings, electrically powered organic beings that converted solar energy or thermal gradients into electricity, with which they powered their bodies as well as electrolyzed water for the hydrogen that gave them lift. They spent their days in the air and their nights tethered to trees, and as far as Derec knew they spent all the time-day or night-thinking. Philosophers all, and the robots had come here to philosophize with them.
Small wonder they had gone off to do so at their first opportunity. Their duty to the humans over once they had delivered them safely to the city, they had taken off before they could be ordered to do something else that interfered with their wishes.
On a hunch, Derec sent via comlink, Adam, Eve, Lucius. Answer me.
He got no reply, which was just what he expected. Still under Avery’s orders not to use their comlinks among themselves, they had shut them off entirely.
He shrugged. “Let them go. They’ll come back when they’re ready.” Until then Derec had other things to do, like figure out what had happened to his careful modifications to the city.
Ariel came down the ramp, shaking her head and tugging at her hair with a brush. “I vote we go find us a shower,” she said vehemently.
“Food first, then shower,” Avery said from behind her. He stepped carefully down the ramp, holding onto the railing for support. Three and a half days without food was probably longer than he had ever fasted before, and his unsteadiness showed it.
Mandelbrot went to his side at once and helped him the rest of the way down to the paved ground. A row of transport booths waited patiently beside the terminal building, only a few paces away, and Mandelbrot led the way toward them without waiting to be ordered.
Another booth came out of the city, moving down the center of the road toward them. It arrived just as they reached the other booths, and a golden-hued robot stepped out of it. Derec recognized the robot immediately by its color and the distinctive markings on its chest and shoulders. He had dealt with this particular robot before, and one of his predecessors before that. This was a supervisor, one of the seven charged with keeping the city functioning smoothly.
“Wohler-9!” he said.
“Master Derec,” Wohler-9 replied. “Welcome back. We were not aware that you were returning.”
“We almost didn’t. We had a fire on the ship and lost our recycler. We just barely made it.”
“I am glad that you are safe. The entire city is glad and eager to serve you. What do you require?”
