Diamond Age or a Young Lady's Illustrated Primer

He wasn't in the central chamber anymore, rather in one of the tunnel's aneurysms with some twenty other people, all just as naked as he was. He knew which tunnel led to the exit (why?) and began to crawl down it, rather stiffly as it seemed that he was stiff and laden with cricks and cramps. Must not have been very athletic sex– more in the Tantric mode.

Sometimes they had sex for days.

How did he know that?

The hallucinations were gone, which was fine with him. He crawled through the tunnels for a long time. If he tried to think about where he was going, he got lost and eventually circled back to where he started. Only when his mind began to wander did he make his way on some kind of autopilot to a long chamber filled with silvery light, sloping upward. This was beginning to look familiar, he had seen this when he was still a young man. He followed it upward until he reached the end, where something unusually stony was under his feet. A hatch opened above him, and several tons of cold seawater landed on his head.

He staggered up onto dry land and found himself in Stanley Park again, gray floor aft, green wall fore. The ferns rustled, and out stepped Kidnapper, who looked fuzzy and green. He also looked unusually dapper for a robotic horse, as Hackworth's bowler hat was perched on top of his head.

Hackworth reached up to feel himself and was astounded to feel his face covered with hair. Several months' growth of beard was there. But even stranger, his chest was much hairier than it had been before. Some of the chest hair was gray, the only gray hairs he had ever seen coming out of his own follicles.

Kidnapper was fuzzy and green because moss had been growing on him. The bowler looked terrible and had moss on it too. Hackworth reached out instinctively and put it on his head. His arm was thicker and hairier than it used to be, a not altogether unpleasing change, and even the hat felt a little tight.

From the Primer, Princess Nell crosses the trail of the enigmatic Mouse Army; a visit to an invalid.

The clearing dimly visible through the trees ahead was a welcome sight, for the forests of King Coyote were surpassingly deep and forever shrouded in cool mists. Fingers of sunlight had begun to thrust between the clouds, and so Princess Nell decided to rest in the open space and, with any luck, bask in the sunlight. But when she reached the clearing, she found that it was not the flowerstrewn greensward she had expected; it was rather a swath that had been carved through the forest by the passage of some titanic force, which had flattened trees and churned up the soil as it progressed. When Princess Nell had recovered from her astonishment and mastered her fear, she resolved to make use of the tracking skills she had learned during her many adventures, so as to learn something about the nature of this unknown creature.

As she soon discovered, the skills of an advanced tracker were not necessary in this case. The merest glance at the trampled soil revealed not (as she had anticipated) a few enormous footprints, but millions of tiny ones, superimposed upon one another in such numbers that no scrap of ground was unmarked by the impressions of tiny claws and footpads.

A torrent of cats had passed this way; even had Princess Nell not recognized the footprints, the balls of loose hair and tiny scats, strewn everywhere, would have told the story. Cats moving in a herd! It was most unfeline behavior. Nell followed their track for some time, hoping to divine the cause of this prodigy. After a few miles the road widened into an abandoned camp freckled with the remains of innumerable small campfires. Nell combed this area for more clues, not without success: she found many mouse droppings here, and mouse footprints around the fires. The pattern of footprints made it clear that the cats had been concentrated in a few small areas, while the mice had apparently had the run of the place.

The final piece of the puzzle was a tiny scrap of twisted rawhide that Nell found abandoned near one of the little campfires. Turning it around in her fingers, Nell realized that it was much like a horse's bridle– except sized to fit around the head of a cat.

She was standing on the trail of a vast army of mice, who rode on the backs of cats in the way that knights ride on horses.

She had heard tales of the Mouse Army in other parts of the Land Beyond and dismissed them as ancient superstitions.

But once, several years ago, in an inn high in the mountains, where Princess Nell had stayed for the night, she had been awakened early in the morning by the sound of a mouse rooting through her pack. .
