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?"
"We live in space," Afriel said flatly. "Space is an unnatural environment, and it takes an unnatural effort from unnatural people to prosper there. Our minds are our tools, and philosophy has to come second. Naturally I've felt those urges you mention. They're just another threat to guard against. I believe in an ordered society. Technology has unleashed tremendous forces that are ripping society apart. Some one faction must arise from the struggle and integrate things. We Shapers have the wisdom and restraint to do it humanely. That's why I do the work I do." He hesitated. "I don't expect to see our day of triumph. I expect to die in some brush-fire conflict, or through assassination. It's enough that I can foresee that day."
"But the arrogance of it, Captain!" she said suddenly. "The arrogance of your little life and its little sacrifice! Consider the Swarm, if you really want your humane and perfect order. Here it is! Where it's always warm and dark, and it smells good, and food is easy to get, and everything is endlessly and perfectly recycled. The only resources that are ever lost are the bodies of the mating swarms, and a little air. A Nest like this one could last unchanged for hundreds of thousands of years. Hundreds... of thousands... of years. Who, or what, will remember us and our stupid faction in even a thousand years?"
Afriel shook his head. "That's not a valid comparison. There is no such long view for us. In another thousand years we'll be machines, or gods." He felt the top of his head; his velvet cap was gone. No doubt something was eating it by now.
The tunneler took them deeper into the asteroid's honeycombed free-fall maze. They saw the pupal chambers, where pallid larvae twitched in swaddled silk; the main fungal gardens; the graveyard pits, where winged workers beat ceaselessly at the soupy air, feverishly hot from the heat of decomposition. Corrosive black fungus ate the bodies of the dead into coarse black powder, carried off by blackened workers themselves three-quarters dead.
Later they left the tunneler and floated on by themselves. The woman moved with the ease of long habit; Afriel followed her, colliding bruisingly with squeaking workers. There were thousands of them, clinging to ceiling, walls, and floor, clustering and scurrying at every conceivable angle.
Later still they visited the chamber of the winged princes and princesses, an echoing round vault where creatures forty meters long hung crooked-legged in midair. Their bodies were segmented and metallic, with organic rocket nozzles on their thoraxes, where wings might have been. Folded along their sleek backs were radar antennae on long sweeping booms. They looked more like interplanetary probes under construction than anything biological. Workers fed them ceaselessly. Their bulging spiracled abdomens were full of compressed oxygen.
Mirny begged a large chunk of fungus from a passing worker, deftly tapping its antennae and provoking a reflex action. She handed most of the fungus to the two springtails, which devoured it greedily and looked expectantly for more.
Afriel tucked his legs into a free-fall lotus position and began chewing with determination on the leathery fungus. It was tough, but tasted good, like smoked meat -- a delicacy he had tasted only once. The smell of smoke meant disaster in a Shaper's colony.
Mirny maintained a stony silence. "Food's no problem," Afriel said. "Where do we sleep?"
She shrugged. "Anywhere... there are unused niches and tunnels here and there. I suppose you'll want to see the Queen's chamber next."
"By all means."
"I'll have to get more fungus. The warriors are on guard there and have to be bribed with food."
She gathered an armful of fungus from another worker in the endless stream, and they moved on. Afriel, already totally lost, was further confused in the maze of chambers and tunnels. At last they exited into an immense lightless cavern, bright with infrared heat from the Queen's monstrous body. It was the colony's central factory. The fact that it was made of warm and pulpy flesh did not conceal its essentially industrial nature. Tons of predigested fungal pap went into the slick blind jaws at one end. The rounded billows of soft flesh digested and processed it, squirming, sucking, and undulating, with loud machinelike churnings and gurglings. Out of the other end came an endless conveyorlike blobbed stream of eggs, each one packed in a thick hormonal paste of lubrication. The workers avidly licked the eggs clean and bore them off to nurseries. Each egg was the size of a man's torso.
The process went on and on. There was no day or night here in the lightless center of the asteroid. There was no remnant of a diurnal rhythm in the genes of these creatures. The flow of production was as constant and even as the working of an automated mine.
"This is why I'm here," Afriel murmured in awe. "Just look at this, Doctor. The Mechanists have cybernetic mining machinery that is generations ahead of ours. But here -- in the bowels of this nameless little world, is a genetic technology that feeds itself, maintains itself, runs itself, efficiently, endlessly, mindlessly. It's the perfect organic tool. The faction that could use these tireless workers could make itself an industrial titan. And our knowledge of biochemistry is unsurpassed. We Shapers are just the ones to do it."
"How do you propose to do that?" Mirny asked with open skepticism. "You would have to ship a fertilized queen all the way to the solar system. We could scarcely afford that, even if the Investors would let us, which they wouldn't."
"I don't need an entire Nest," Afriel said patiently. "I only need the genetic information from one egg. Our laboratories back in the Rings could clone endless numbers of workers."
