Diamond Age or a Young Lady's Illustrated Primer

He stopped for a moment, took a deep breath, and seemed to stir awake; when he spoke again, it was in a clearer and stronger voice. "Of course, it can't be allowed– the Feed is not a system of control and oppression, as CryptNet would maintain. It is the only way order can be maintained in modern society– if everyone possessed a Seed, anyone could produce weapons whose destructive power rivalled that of Elizabethan nuclear weapons. This is why Protocol Enforcement takes such a dim view of CryptNet's activities."

The trees parted to reveal a long blue lake below them. Kidnapper found its way to a road, and Hackworth spurred it on to a hand-gallop. Within a few hours, father and daughter were settling into bunkbeds in a second-class cabin of the airship Falkland Islands, bound for London.

From the Primer, Princess Nell's activities as Duchess of Turing; the Castle of the Water-gates; other castles; the Cipherers' Market; Nell prepares for her final journey.

Princess Nell remained in Castle Turing for several months. During her quest for the twelve keys, she had entered many castles, outwitted their sentries, picked their locks, and rifled their treasuries; but Castle Turing was an altogether different place, a place that ran on rules and programs that were devised by men and that could be rewritten by one who was adept in the language of the ones and zeroes. She need not content herself with sneaking in, seizing a trinket, and fleeing. Castle Turing she made her own. Its demesne became Princess Nell's kingdom.

First she gave the Duke of Turing a decent burial. Then she studied his books until she had mastered them. She acquainted herself with the states by which the soldiers, and the mechanical Duke, could be programmed. She entered a new master program Into the Duke and then restarted the turning of the mighty Shaft that powered the castle. Her first efforts were unsuccessful, as her program contained many errors. The original Duke himself had not been above this; he called them bugs, in reference to a large beetle that had become entangled in one of his chains during an early experiment and brought the first Turing machine to a violent halt. But with steadfast patience, Princess Nell resolved these bugs and made the mechanical Duke into her devoted servant. The Duke in turn had the knack of putting simple programs into all of the soldiers, so that an order given him by Nell was rapidly disseminated into the entire force.

For the first time in her life, the Princess had an army and servants. But it was not a conquering sort of army, because the springs in the soldiers' backs unwound rapidly, and they did not have the adaptability of human soldiers. Still, it was an effective force behind the walls of the castle and made her secure from any conceivable aggressor. Following maintenance schedules that had been laid down by the original Duke, Princess Nell set the soldiers to work greasing the gears, repairing cracked shafts and worn bearings, and building new soldiers out of stockpiled parts.

She was heartened by her success. But Castle Turing was only one of seven ducal seats in this kingdom, and she knew she had much work to do.

The territory around the castle was deeply forested, but grassy ridges rose several miles away, and standing on the castle walls with the original Duke's spyglass, Nell was able to see wild horses grazing there. Purple had taught her the secrets of mastering wild horses, and Duck had taught her how to win their affection, and so Nell mounted an expedition to these grasslands and returned a week later with two beautiful mustangs, Coffee and Cream. She equipped them with fine tack from the Duke's stables, marked with the T crest-for the crest was hers now, and she could with justification call herself the Duchess of Turing. She also brought a plain, unmarked saddle so that she could pass for a commoner if need be-though Princess Nell had become so beautiful over the years and had developed such a fine bearing that few people would mistake her for a commoner now, even if she were dressed in rags and walking barefoot.

Lying in her bunkbed in Madame Ping's dormitory, reading these words from a softly glowing page in the middle of the night, Nell wondered at that. Princesses were not genetically different from commoners.
