“There must be thousands of them,” Afriel said.
“I said a hundred thousand in my last report, but that was before I had fully explored the Nest. Even now there are long stretches I haven’t seen. They must number close to a quarter of a million. This asteroid is about the size of the Mechanists’ biggest base — Ceres. It still has rich veins of carbonaceous material. It’s far from mined out.”
Afriel closed his eyes. If he was to lose his goggles, he would have to feel his way, blind, through these teeming, twitching, wriggling thousands. “The population’s still expanding, then?”
“Definitely,” she said. “In fact, the colony will launch a mating swarm soon. There are three dozen male and female alates in the chambers near the Queen. Once they’re launched, they’ll mate and start new Nests. I’ll take you to see them presently.” She hesitated. “We’re entering one of the fungal gardens now.”
One of the young springtails quietly shifted position. Grabbing the tunneler’s fur with its forelimbs, it began to gnaw on the cuff of Afriel’s pants. Afriel kicked it soundly, and it jerked back, retracting its eyestalks.
When he looked up again, he saw that they had entered a second chamber, much larger than the first. The walls around, overhead, and below were buried under an explosive profusion of fungus. The most common types were swollen barrel-like domes, multibranched massed thickets, and spaghetti-like tangled extrusions that moved very slightly in the faint and odorous breeze. Some of the barrels were surrounded by dim mists of exhaled spores.
“You see those caked-up piles beneath the fungus, its growth medium?” Mirny said.
“Yes.”
“I’m not sure whether it is a plant form or just some kind of complex biochemical sludge,” she said. “The point is that it grows in sunlight, on the outside of the asteroid. A food source that grows in naked space! Imagine what that would be worth, back in the Rings.”
“There aren’t words for its value,” Afriel said.
“It’s inedible by itself,” she said. “I tried to eat a very small piece of it once. It was like trying to eat plastic.”
“Have you eaten well, generally speaking?”
“Yes. Our biochemistry is quite similar to the Swarm’s. The fungus itself is perfectly edible. The regurgitate is more nourishing, though. Internal fermentation in the worker hindgut adds to its nutritional value.”
Afriel stared. “You grow used to it,” Mirny said. “Later I’ll teach you how to solicit food from the workers. It’s a simple matter of reflex tapping — it’s not controlled by pheromones, like most of their behavior.” She brushed a long lock of clumped and dirty hair from the side of her face. “I hope the pheromonal samples I sent back were worth the cost of transportation.”
“Oh, yes,” said Afriel. “The chemistry of them was fascinating. We managed to synthesize most of the compounds. I was part of the research team myself.” He hesitated. How far did he dare trust her? She had not been told about the experiment he and his superiors had planned. As far as Mirny knew, he was a simple, peaceful researcher, like herself. The Shapers’ scientific community was suspicious of the minority involved in military work and espionage.
As an investment in the future, the Shapers had sent researchers to each of the nineteen alien races described to them by the Investors. This had cost the Shaper economy many gigawatts of precious energy and tons of rare metals and isotopes. In most cases, only two or three researchers could be sent; in seven cases, only one. For the Swarm, Galina Mirny had been chosen. She had gone peacefully, trusting in her intelligence and her good intentions to keep her alive and sane. Those who had sent her had not known whether her findings would be of any use or importance. They had only known that it was imperative that she be sent, even alone, even ill-equipped, before some other faction sent their own people and possibly discovered some technique or fact of overwhelming importance. And Dr Mirny had indeed discovered such a situation. It had made her mission into a matter of Ring security. That was why Afriel had come.
“You synthesized the compounds?” she said. “Why?”
Afriel smiled disarmingly. “Just to prove to ourselves that we could do it, perhaps.”
She shook her head. “No mind-games, Dr Afriel, please. I came this far partly to escape from such things. Tell me the truth.”
Afriel stared at her, regretting that the goggles meant he could not meet her eyes. “Very well,” he said. “You should know, then, that I have been ordered by the Ring Council to carry out an experiment that may endanger both our lives.”
Mirny was silent for a moment. “You’re from Security, then?”
“My rank is captain.”
“I knew it… I knew it when those two Mechanists arrived. They were so polite, and so suspicious — I think they would have killed me at once if they hadn’t hoped to bribe or torture some secret out of me. They scared the life out of me, Captain Afriel… You scare me, too.”
“We live in a frightening world, Doctor. It’s a matter of faction security.”
“Everything’s a matter of faction security with your lot,” she said. “I shouldn’t take you any farther, or show you anything more. This Nest, these creatures — they’re not intelligent, Captain. They can’t think, they can’t learn. They’re innocent, primordially innocent. They have no knowledge of good and evil. They have no knowledge of anything. The last thing they need is to become pawns in a power struggle within some other race, light-years away.”
The tunneler had turned into an exit from the fungal chambers and was paddling slowly along in the warm darkness. A group of creatures like gray, flattened basketballs floated by from the opposite direction. One of them settled on Afriel’s sleeve, clinging with frail whiplike tentacles. Afriel brushed it gently away, and it broke loose, emitting a stream of foul reddish droplets.
“Naturally I agree with you in principle, Doctor,” Afriel said smoothly. “But consider these Mechanists. Some of their extreme factions are already more than half machine. Do you expect humanitarian motives from them? They’re cold, Doctor — cold and soulless creatures who can cut a living man or woman to bits and never feel their pain. Most of the other factions hate us. They call us racist supermen. Would you rather that one of these cults do what we must do, and use the results against us?”
“This is double-talk.” She looked away. All around them workers laden down with fungus, their jaws full and guts stuffed with it, were spreading out into the Nest, scuttling alongside them or disappearing into branch tunnels departing in every direction, including straight up and straight down. Afriel saw a creature much like a worker, but with only six legs, scuttle past in the opposite direction, overhead. It was a parasite mimic. How long, he wondered, did it take a creature to evolve to look like that?
“It’s no wonder that we’ve had so many defectors, back in the Rings,” she said sadly. “If humanity is so stupid as to work itself into a corner like you describe, then it’s better to have nothing to do with them. Better to live alone. Better not to help the madness spread.”
“That kind of talk will only get us killed,” Afriel said. “We owe an allegiance to the faction that produced us.”
“Tell me truly, Captain,” she said. “Haven’t you ever felt the urge to leave everything — everyone — all your duties and constraints, and just go somewhere to think it all out? Your whole world, and your part in it? We’re trained so hard, from childhood, and so much is demanded from us. Don’t you think it’s made us lose sight of our goals, somehow?”
