Free Under Heaven by Guy Gavriel Kay

beyond the Long Wall, subdued and co-opted by the Kitan. Even the military governors were often foreigners now. Certainly the most powerful one was.
    It marked a change. A large one.
    The soldiers served year-round and, for years now, were paid from the imperial treasury and supported by a virtual army of peasants and labourers building forts and walls, supplying food and weapons and clothing and entertainment of any and all kinds.
    It made for better-trained fighters familiar with their terrain, but a standing army of this size did not come without costs—and increased taxes were only the most obvious consequence.
    In years and regions of relative peace, without drought or flood, with wealth now flowing at an almost unimaginable rate into Xinan and Yenling and the other great cities, the cost of the new armies was bearable. In hard years it became a problem. And other issues, less readily seen, were growing. At the lowest ebb, of a person or a nation, the first seeds of later glory may sometimes be seen, looking back with a careful eye. At the absolute summit of accomplishment the insects chewing from within at the most extravagant sandalwood may be heard, if the nights are quiet enough.
     
    A QUIET-ENOUGH NIGHT. Wolves had been howling in the canyon earlier, but had stopped. The darkness was giving way, for those on watch on the ramparts of Iron Gate Fort, to a nearly-summer sunrise. Pale light pulling a curtain of shadows back—as in a puppet show at a town market—from the narrow space between ravine walls.
    Though that, thought Wujen Ning, from his post on the ramparts, was not quite right. Street theatre curtains were pulled to the side—he’d seen them in Chenyao.
    Ning was one of the native-born Kitan here, having followed his father and older brothers into the army. There was no family farm for him to rely upon for an income, or return to visit. He wasn’t married.
    He spent his half-year leave time in the town between Iron Gate and Chenyao. There were wine shops and food sellers and women to take his strings of cash. Once, given two weeks’ leave, he’d gone to Chenyao itself, five days away. Home was too far.
    Chenyao had been, by a great deal, the biggest city he’d ever seen. It had frightened him, and he’d never gone back. He didn’t believe the others when they said it wasn’t that large, as cities went.
    Here in the pass, in the quiet of it, the dawn light was filtering downwards. It struck the tops of the cliffs first, pulling them from shadow, and worked its way towards the still-dark valley floor as the sun rose over the mighty empire behind them.
    Wujen Ning had never seen the sea, but it pleased him to imagine the vast lands of Kitai stretching east to the ocean and the islands in it where immortals dwelled.
    He glanced down at the dark, dusty courtyard. He adjusted his helmet. They had a commander now who was obsessed with helmets and properly worn uniforms, as if a screaming horde of Tagurans might come storming down the valley at any moment and sweep over the fortress walls if someone’s tunic or sword belt was awry.
    As if, Ning thought. He spat over the wall through his missing front tooth. As if the might of the Kitan Empire in this resplendent Ninth Dynasty, and the three hundred soldiers in this fort that commanded the pass, were a nuisance like mosquitoes.
    He slapped at one of those on his neck. They were worse to the south, but this pre-dawn hour brought out enough of the bloodsuckers to make for annoyance. He looked up. Scattered clouds, a west wind in his face. The last stars nearly gone. He’d be off duty at the next drum, could go down to breakfast and sleep.
    He scanned the empty ravine, and realized it wasn’t empty.
    What he saw, in the mist slowly dispersing, made him shout for a runner to go to the commander.
    A lone man approaching before sunrise wasn’t a threat, but it was unusual enough to get an officer up on the wall.
    Then, as he came nearer, the rider lifted a
