He looked around him. The immediate streetscape seemed composed of bits and pieces from several stages of the city’s development, a weird composite of what Derec had observed during his several stays there.

But where were the robots?

If this was a lucid dream, maybe the reason he hadn’t seen any yet was that he hadn’t guided any into the scene. Maybe they were waiting inside the buildings to be summoned. Maybe he should do so, before he panicked. But which one could he bring onstage? How about Lucius, the robot who had created the city’s one authentic artistic masterpiece, the breathtaking tetragonal, pyramidal building-sculpture entitled “Circuit Breaker”? He’d be a good choice since, as the victim of a bizarre roboticide, he no longer existed. It certainly would be pleasant to see old Lucius again, his body so unrobotically stooped, if only to chat with him about art. There hadn’t been much art in his life lately, especially if you didn’t count the rather breathtaking spectacle of a thousand blackbodies spread across the sky. That was pretty, but it wasn’t art.

He wondered why his thoughts were rambling so. Had the Silversides disturbed his mind’s equilibrium that much? Forget them. Forget them now. Get a normal robot into the dream. One of the most unforgettable robots he had known. Avernus, say. Let’s see his stern visage again, his jet-black metallic skin, his interchangeable hands. He concentrated on Avernus, but the robot didn’t appear. How about Euler and his glowing photocell eyes? Nope, no deal. Let’s try for Wohler, then, before he went nonfunctional trying to save Ariel on the outer wall of the Compass Tower. Golden and impressive, Wohler would be a wonderful choice. But no Wohler responded to his summons. He would have to talk to Ariel about this. As a lucid dream, it was shaping up as one hell of a failure.

Ariel, in her compartment aboard the ship, was also dreaming. Hers was not, however, a lucid dream. Deeper than that, it was a clearcut nightmare.

Jacob Winterson, the humaniform robot who had been her servant, existed again. Jacob had been destroyed by Neuronius, one of the flying aliens called blackbodies. He had blown up and mangled most of Jacob (and himself in the bargain). The few charred pieces that remained were now buried in some unmarked area of the agricultural community she had initiated as a political compromise with the blackbodies. The compromise had worked. They had been about to destroy their planet’s new robot city entirely because it was a threat to their weather systems; however, an agricultural community was acceptable to all sides.

She missed Jacob. Very much. In that comfortable, detached way a human could love a robot, she had loved him. Not that it could ever have been real love. She was too much in love with Derec to be unfaithful to him except in dreams. On the other hand, she could not deny that she had not sometimes been romantically attracted toward the handsome and imperturbable humaniform robot.

In the dream, Jacob sat in front of a computer terminal, his humanlike fingers flying over the keyboard, pressing keys as if he wanted to push them all the way through, making the screen shake with the ferocity of his entries.

She asked him what he was doing. He said he was searching for the formula that would transform a humaniform robot into a human being. There was no such formula, she told him. When he turned toward her, his eyes seemed filled with a frightening human anger. He protested that there were at least a hundred Earth and Spacer legends in which creatures changed into human beings. Statues, puppets, fish, trees, all became human in such myths. He was certain, he said with an un-Jacobian shrillness, that there had to be a formula by which he, too, could be transmogrified.

Why did the Compass Tower look so diseased? Derec asked himself. Was it possible for him, as a lucid dreamer, to change that? He concentrated on the building’s shape, trying to restore it to its architecturally magnificent pyramidal form. But nothing happened. If anything, the tower became uglier, and he had to look away from it.

In the distance something came toward him, traveling down the street at a high speed. As it passed by buildings, the buildings changed. When it neared, he saw it was a vehicle, but one quite unlike any Robot City mode of transportation. It ran on three thick wheels, making it vaguely resemble a jitney, the smaller, lighter utility type of vehicle used for taxiing around the city. The vehicle’s body was misshapen, as if a lot of ungeometric chunks had been welded together on a long central stem. It was colored black and gray in an illogical and splotchy fashion.

Still certain he was in the midst of a lucid dream, Derec stood defiantly in the center of the roadway -daring the vehicle to come to a screeching stop at his feet. Which it did. Good, he thought, I ’ m in control of the dream at last. Just watch me now.

A large hatch at the top of the vehicle sprang open with an explosive sound, and Dr. Avery, his father, pulled himself through the opening. What kind of a lucid dream was this? The last person he wanted to see was his megalomaniacal father, interfering in a dream in just the way he’d interfered with Derec’s life, injecting him with chemfets and transforming him into a walking computer. Half-computer, anyway.

Avery was looking more demented than usual. His eyes, usually intense, now glowed with an overdramatic madness. In fact, Avery looked so exaggerated that Derec felt he could relax. No reason to be afraid, after all, just a dream. A dream he would seize control of at any moment.

Ariel placed her hand upon Jacob’s. His hand, she noted, felt soft, more like human than humaniform. She told him to stop. There was no need for him to become human. Even if he found a formula, it would be foolish to use it. As a humaniform robot, Jacob had all the virtues of human existence without all the miseries, without human physical and emotional pains.

Jacob turned away from the computer and looked at Ariel, for a moment a humanlike sadness in his eyes.

“Don’t you see?” he said, “I want the misery. I want to feel what a human feels. Pain, happiness, love. I want to love you, Mistress Ariel.”

She put a finger on his lips. In contrast to his hand, they felt robotic, hard metal lips that could, if she pressed hard enough, make her fingertip bleed. She almost wanted to test that out. If she tried to cut her hand, would Jacob be able to invoke the First Law of Robotics-the part stating that a robot could not allow a human to come to harm-fast enough to prevent her from succeeding?

“You can’t love me, Jacob,” she said tenderly. “I love Derec, so there’s no point in your loving me. It would be-what do they call it in romances-unrequited.”

“That wouldn’t matter. I would be happy with that, too. I could respond to it, as in your great literary works. I could, like one of your legendary lovers, die falling off a bridge or swimming a river or with a vial of poison and a great dagger plunging in-”

“Hush, Jacob. Please stop. I wouldn’t want you to die for me.”

“I am already dead.”

“No, don’t say that. You’re here. You’re-”

“In a grave.”

“Jacob-”

“A rotting scrap pile of metal, spare parts covered by soil.”

His words were so fiercely spoken they frightened her. She backed away from him.

Dr. Avery was dressed in a black-and-gray silver-buttoned uniform that seemed too militaristic for a scientist.

“You look bemused,” he said, then added almost contemptuously: “…my son. What is bothering you?”

“It’s well, it’s that this is my dream, and I’m supposed to be in control, and you’re not welcome in it.”
