How she read the air, he could not guess, but she seemed to be able to see thermals somehow. She spiraled up the one she was in, then began a long glide down over the Third Canal, and caught another on the opposite side. And just as Kiron had guessed, down below were the barracks of the army, the shops and cook shops and drink shops that catered to them, the homes of those who ran and served in those shops, and the whole support structure of armories and stables, forges and supply warehouses, Healers and training grounds and practice fields that an army needed.

And here, too, were the temples of those gods that loved soldiers, and that soldiers loved, and the pens of animals waiting to be sacrificed.

And, as he had expected, the Jousters’ Compound.

It looked very like its Tian counterpart, with some differences. Three fourths of the pens had hot water wallows, not sand pits. And in those pens that had wallows, the dragons were a little smaller than those he was used to, their colors darker. They looked up as soon as they spotted him, of course, their heads weaving back and forth on their long necks. The familiar sounds of slightly irritated dragons drifted up to him from below.

Well, he didn’t want to make any trouble for anyone, especially not the dragon boys who might have to calm their charges if they got any more restless, so he angled Avatre away, curious though she was to look at these odd and unfamiliar relatives.

The Third Ring did not have a hill; whether this was by accident or chance, Kiron could not tell. It might merely have been that the Third Ring covered so much area that the ground that had been dug to make the Fourth Canal was barely enough to raise it all above flood level. Then again, since the Third Ring was devoted entirely to Alta’s military, it could be that no one had felt the need to be physically higher than anyone else.

Beyond the Fourth Canal it was quite clear that the land had been given over to farming, and Kiron had no real interest in seeing what lay there. He knew that three more canals lay beyond the Fourth, probably settled as farmers prospered and their sons desired farms of their own, and continued what had now become habit and custom, of building up farmland by digging out a canal that was as much for drainage as for protection. The canals were all linked by subchannels that cut across the rings like the spokes of a wheel; more spokes were formed by the bridges that linked the roads of the Rings. It was unexpectedly beautiful, and when he thought about all of the labor that had gone into creating the city, his head just swam.

Other than the dragons of the Jousters’ Compound, no one looked up when the shadow of a flying dragon passed over them. Avatre soared from thermal to thermal above the Third Ring to her heart’s content. There were boats out in the canals; little fishing boats, larger barges. Some were hauling cargo from the outer to the inner rings; some were clearly pleasure boats, or the boats carrying officials about on their duties. As he watched, he even saw a species of small boat that seemed to be coming in to land whenever someone on shore hailed it. After a moment, it came to him that these boats must be for hire, to take people wherever in the Rings they wished to go, like hired litters or chariots. That would be much faster than walking, though he doubted that it would be faster than driving a chariot.
