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.
