Nothing ever goes as you expect, Lews Therin murmured. Expect nothing, and you will not be surprised. Expect nothing. Hope for nothing. Nothing.

Suppressing the voice, Rand dismounted.

Idrien came to meet him with a curtsy. As usual, when she rose it was something of a shock to realize yet again that she was barely as tall as his chest. “Welcome to the School of Cairhien, my Lord Dragon.” Her voice was surprisingly sweet and youthful, a startling contrast to her blunt face. He had heard it harden, though, with students and teachers; Idrien held a tight rein on the school.

“How many spies do you have in the Sun Palace?” he asked mildly. She looked startled, perhaps that he would suggest such a thing, but more likely because the question was not proper manners in Cairhien.

“We have prepared a small display.” Well, he had not really expected an answer. She eyed the two Aiel like a woman eyeing two large and muddy dogs of uncertain temperament, but contented herself with a sniff. “If my Lord Dragon will follow me?”

He followed, frowning. A display of what?

The entry hall of the school was a vast chamber of polished dark gray columns and pale gray floor tiles, with a gray-veined marble balcony all the way around three spans up. Now it was largely filled with . . . contraptions. The teachers crowding in behind him went running to them. Rand stared, suddenly remembering what Berelain had said about the school making things. But what?

Idrien told him—after a fashion—leading him from one to the next, where men and women explained what they had created. He even understood some of it.

An array of screens and scrapers and crocks full of linen scraps produced finer paper than anyone made now, or so its inventor said. A great hulking shape of levers and huge flat plates was a printing press, much better than those already in use, according to its maker. Dedric showed considerable interest in that, until Jalani apparently decided he should be watching for somebody trying to attack the Car’a’carn: she trod hard on his foot, and he limped after Rand. There was a plow on wheels meant to turn six furrows at once—Rand could recognize that, at least; he thought it might work—and another thing with shafts for horses that was meant to harvest hay in place of men with scythes, and a new sort of loom that was easier to operate, so the fellow who made it said. There were painted wooden models of viaducts to carry water to places where the wells were going dry, of new drains and sewers for Cairhien, even a tabletop exhibit with tiny figures of men and carts, cranes and rollers, meant to show how roads could be built and paved as well as they had in years long gone.

Rand did not know whether any of it would work, but some looked worth trying. That plow, for instance, could be handy if Cairhien was ever to feed itself again. He would tell Idrien to build it. No, he would tell Berelain to tell her. Always follow lines of authority in public view, Moiraine had said, unless you mean to undercut someone and bring them down.

Among the teachers he knew was Kin Tovere, a stocky lensmaker who kept wiping his bald head with a striped handkerchief. Aside from looking glasses in various sizes—“Count the hairs in a man’s nose at a mile,” he said; that was how he talked—he had a lens as big across as his head, a sketch of the looking glass to hold it and more like it, a thing six paces long, and a scheme for looking at the stars, of all things. Well, Kin always wanted to look at things far off.

Idrien wore a look of quiet satisfaction while Rand studied Master Tovere’s sketch. She was not much for anything but the practical. During the siege of Cairhien, she herself had built a huge crossbow, all levers and pulleys, that hurled a small spear a full mile hard enough to drive through a man. Had she her way, there would be no time wasted on anything not real and solid.

“Build it,” Rand told Kin. Maybe it was of no real use, not like the plow, but he liked Tovere. Idrien sighed and shook her head. Tovere beamed. “And I’m giving you a prize of a hundred gold crowns. This looks interesting.” That produced a buzz, and it was close whether Idrien’s jaw or Tovere’s dropped farther.

Other things in the hall made Tovere seem as levelheaded as the would-be road-builder. The round-faced fellow who did something with cow dung that ended with a bluish flame burning at the end of a brass tube; even he did not seem to know what it was for. The lanky young woman whose display was mainly a shell of paper moored by strings and kept aloft by the heat rising from a small fire in a brazier. She mumbled something about flying—he was sure that was what she said—and birds’ wings being curved—she had sketches of birds, and of what seemed to be wooden birds—but she was so tongue-tied meeting the Dragon Reborn that he could not understand another word, and Idrien certainly could not explain what it was about.

And then there was the balding man with an assemblage of brass tubes and cylinders, rods and wheels, all covering a heavy wooden table freshly gouged and scraped, some gouges nearly deep enough to pierce the tabletop. For some reason half the man’s face and one of his hands were swathed in bandages. As soon as Rand appeared in the entry hall, he had begun anxiously building a fire under one of the cylinders. When Rand and Idrien stopped in front of him, he moved a lever and smiled proudly.

The contraption began to quiver, steam hissing out from two or three places. The hiss grew to a shriek, and the thing began trembling. It groaned ominously. The shriek became ear-piercing. It shook so hard the table moved. The balding man threw himself at the table, fumbling a plug loose on the largest cylinder. Steam rushed out in a cloud, and the thing went still. Sucking burned fingers, the man managed a weak grin.

“Very nice brasswork,” Rand said before letting Idrien lead him away. “What was that?” he asked quietly when they were out of earshot.

She shrugged. “Mervin will not tell anyone. Sometimes there are bangs in his rooms loud enough to make doors tremble, and he has scalded himself six times so far, but he claims it will bring a new Age when he makes it work.” She glanced at Rand uneasily.

“Mervin is welcome to bring it if he can,” he told her dryly. Maybe the thing was supposed to make music? All those shrieks? “I don’t see Herid. Did he forget to come down?”

Idrien sighed again. Herid Fel was an Andoran who somehow had ended up reading in the Royal Library here—a student of history and philosophy, he called himself—and hardly the sort to endear himself to her. “My Lord Dragon, he never comes out of his study except to
