twenty in diameter. It swarmed with members of the Nest.
There were hundreds of them. Most of them were workers, eight-legged and furred, the size of Great Danes. Here and there were members of the warrior caste, horse-sized furry monsters with heavy fanged heads the size and shape of overstuffed chairs.
A few meters away, two workers were carrying a member of the sensor caste, a being whose immense flattened head was attached to an atrophied body that was mostly lungs. The sensor had great platelike eyes, and its furred chitin sprouted long coiled antennae that twitched feebly as the workers bore it along. The workers clung to the hollowed rock of the chamber walls with hooked and suckered feet.
A paddle-limbed monster with a hairless, faceless head came sculling past them, through the warm reeking air. The front of its head was a nightmare of sharp grinding jaws and blunt armored acid spouts. âA tunneler,â Mirny said. âIt can take us deeper into the Nestâcome with me.â She launched herself toward it and took a handhold on its furry, segmented back. Afriel followed her, joined by the two immature springtails, who clung to the thingâs hide with their forelimbs. Afriel shuddered at the warm, greasy feel of its rank, damp fur. It continued to scull through the air, its eight fringed paddle feet catching the air like wings.
âThere must be thousands of them,â Afriel said.
âI 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 havenât seen. They must number close to a quarter of a million. This asteroid is about the size of the Mechanistsâ biggest baseâCeres. It still has rich veins of carbonaceous material. Itâs far from mined out.â
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. âThe populationâs still expanding, then?â
âDefinitely,â she said. âIn fact, the colony will launch a mating swarm soon. There are three dozen male and female alates in the chambers near the Queen. Once theyâre launched, theyâll mate and start new Nests. Iâll take you to see them presently.â She hesitated. âWeâre entering one of the fungal gardens now.â
One of the young springtails quietly shifted position. Grabbing the tunnelerâs fur with its forelimbs, it began to gnaw on the cuff of Afrielâs 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 barrellike 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.
âYou see those caked-up piles beneath the fungus, its growth medium?â Mirny said.
âYes.â
âIâm not sure whether it is a plant form or just some kind of complex biochemical sludge,â she said. âThe 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.â
âThere arenât words for its value,â Afriel said.
âItâs inedible by itself,â she said. âI tried to eat a very small piece of it once. It was like trying to eat plastic.â
âHave you eaten well, generally speaking?â
âYes. Our biochemistry is quite similar to the Swarmâs. The fungus itself is perfectly edible. The regurgitate is more nourishing, though. Internal fermentation in the worker hindgut adds to its nutritional value.â
Afriel stared. âYou grow used to
