Larry Niven - The Ringworld Engineers

“What can you offer in return?”

Here now, wasn’t this woman utterly at Louis Wu’s mercy? Well, never mind. “I will attempt to find out if I can save the Ringworld,” he said, and was somewhat astonished to realize that it was what he most desired. “If I can, I will, no matter what the cost. If I decide the Ringworld can’t be saved, I will try to save myself, and you if it’s convenient.”

She stood. “A promise, empty of meaning. You offer me your madness as if it held real value!”

“Vala, haven’t you dealt with madmen before?” Louis was amused.

“I have never dealt with even sane aliens! I am only a student!”

“Calm down. What else can I offer you? Knowledge? I’ll share my knowledge freely, such as it is. I know how the City Builders’ machines failed, and who caused it.” It seemed safe to assume that the City Builders were Halrloprillalar’s species.

“More madness?”

“You’ll have to decide that for yourself. And… I can give you my flying belt and eyepieces when I’m through with them.”

“When is that likely to be?”

“When and if my companion returns.” The lander held another flying belt and set of goggles, intended for Halrloprillalar. “Or let them be yours when I die. And I can give you half my store of cloth now. Strips of it would let you repair some of the City Builders’ old machines.”

Vala thought it over. “I wish I were more skilled. Well, then, I agree to all of your requirements.”

“I agree to yours.”

She began to take off her clothes and jewelry. Slowly, seemingly titillatingly… until Louis saw what she was doing: stripping herself of all possible weapons. He waited until she was quite naked, then imitated her, dropping the flashlight-laser and goggles and the pieces of impact armor some distance from her, adding even his chronometer.

They made love, then, but it wasn’t love. The madness of last night was gone with the vampires. She asked his preferred technique, then insisted, and he chose the missionary position. It was too much a formality. Perhaps it was meant to be. Afterward, when she went to stir the cooking pot, he was careful that she didn’t get between him and his weapons. It felt like that kind of situation.

She came back to him, and he explained that his kind could make love more than once.

He sat cross-legged with Vala in his lap, her legs closed tight around his hips. They stroked each other, aroused each other, learned each other. She liked having her back scratched. Her back was muscular, her torso wider than his own. A strip of her hair ran all the way down her spine. She had fine control of the muscles of her vagina. The fringe of beard was very soft, very fine.

And Louis Wu had a plastic disc under the hair at the crown of his head.

They lay in each other’s arms, and she waited.

“Even if you don’t have electricity, you must know about it,” Louis said. “The City Builders used it to run their machines!”

“Yes. We can make electricity from the flow of a river. Tales tell that endless electricity came from the sky before the fall of the City Builders.”

Which was accurate enough. There were solar power generators on the shadow squares, and they beamed the power to collectors on the Ringworld. Naturally the collectors used superconducting cables, and naturally they had failed.

“Well, then. If I let a very fine wire down into my brain in the right place — which I did — then a very little bit of electric power will tickle the nerves that register pleasure.”

“What is it like?”

“Like getting drunk without the hangover or the dizziness. Like rishathra, or real mating, without needing to love anyone but yourself and without needing to stop. But I stopped.”

“Why?”

“An alien had my electric source. He wanted to give me orders. But I was ashamed before that.”

“The City Builders never had wires in their skulls. We would have found them when we searched the ruined cities. Where is this custom practiced?” she asked. Then she rolled away from him and stared at him in horror.

It was the sin he regretted most often: not keeping his mouth shut. He said, “I’m sorry.”

“You said strips of that cloth would — What is that cloth? ”

“It conducts electric current and magnetic fields with no loss. Superconductor, we call it.”

“Yes, that was what failed the City Builders. The… superconductor rotted. Your cloth will rot too, will it not? How long?”

“No. It’s a different kind.”

She screamed it at him. “How do you know that, Louis Wu?”

“The Hindmost told me. The Hindmost is an alien who brought us here against our will. He left us with no way home.”

“This Hindmost, he took you as slaves?”

“He tried to. Humans and kzinti, we make poor slaves.”

“Is his word good?”

Louis grimaced. “No. And he took the superconductor cloth and wire when he fled his world. He didn’t have time to make it. He must have known where it was, in storage. Like the other things he brought, the stepping discs: it must have been readily available.” And he knew instantly that something was wrong, but it took him a moment to know what it was.

The translator had stopped speaking too soon.

Then it spoke with a very different voice. “Louis, is it wise to, tell her these things?”

“She guessed part of it,” Louis said. “She was about to blame me for the Fall of the Cities. Give me back my translator.”

“Can I allow you this ugly suspicion? Why would my people perform so malicious an act?”

“Suspicion? You son of a bitch.” Vala knelt watching him with big eyes, listening to him talk to himself in gibberish. She couldn’t hear the Hindmost’s voice in his earphones. Louis said, “They kicked you out as Hindmost and you ran. You grabbed what you could and ran. Stepping discs and superconductor cloth and wire and a ship. Discs were easy. You must make them by the million. But where would you find superconductor cloth just waiting for you? And you knew it wouldn’t rot on the Ringworld!”

“Louis, why would we do such a thing?”

“Trade advantage. Give me back my translator!”

Valavirgillin got up. She pulled the pot a little out from the fire, stirred it, tasted. She disappeared toward the vehicle and returned with two wooden bowls, which she filled with a dipper.

Louis waited uneasily. The Hindmost could leave him stranded, with no translator. Louis wasn’t good with languages…

“All right, Louis. It wasn’t planned this way, and it happened before my time. We were searching for a way to expand our territory with minimal risk. The Outsiders sold us the location of the Ringworld.”

The Outsiders were cold, fragile beings who roamed throughout the galaxy in slower-than-light craft. They traded in knowledge. They might well have known of the Ringworld, and sold the information to puppeteers, but… ”Wait a minute. Puppeteers are afraid of spaceflight.”

“I overcame that fear. If the Ringworld had proved suitable, then one spaceflight in an individual’s lifetime is no great risk. We would have flown in stasis, of course. From what the Outsiders told us, and from what we learned via telescopes and automatic probes, the Ringworld seemed ideal. We had to investigate.”

“An Experimentalist faction?”

“Of course. Still, we hesitated to contact so powerful a civilization. But we analyzed Ringworld superconductors through laser spectroscopy. We made a bacterium that could feed on it. Probes seeded the superconductor plague across the Ringworld. You guessed as much?”

“That much, yah.”

“We were to follow with trading ships. Our traders would come opportunely to the rescue. They would learn all we needed to know, and gain allies too.” Clear and musical, the puppeteer’s voice held no trace of guilt, nor even embarrassment.
