She came on the first day of a new moon, borne in a litter very similar to the one her father had used for the meeting. Genghis watched as the honor guard of a hundred men kept close formation around her. He was amused to see that the mounts were not of the high quality he had come to expect. Rai Chiang did not intend to lose these ones as well, even to escort a daughter.

The litter was placed on the ground just a few paces from Genghis as he waited in full armor. His father's sword was on his hip and he touched it for luck, mastering his impatience. He could see the soldiers of the city were angry at having to give her up, and he smiled with genuine pleasure at them, drinking in their frustration. As he had requested, Ho Sa had come out of the city with them. He, at least, wore a cold expression of which Genghis could approve, showing nothing of his inner feelings.

When the daughter of the king stepped out onto the ground, there was a murmur of appreciation from the warriors who had gathered to witness this last sign of their triumph. She was dressed in white silk embroidered with gold, so that she shone in the sun. Her hair was bound high on her head with pins of silver, and Genghis took in a breath at the flawless beauty of her white skin. In comparison to the women of his people, she was a dove amongst crows, though he did not say it aloud. Her eyes were dark pools of despair as she walked to him. She did not look at him, but instead lowered herself elegantly to the ground with her wrists crossed in front of her.

Genghis felt the anger in her father's soldiers swell, but he ignored them. If they moved, his archers would kill them before they could draw a blade.

"You are welcome in my ger, Chakahai," he said softly. Ho Sa murmured a translation, his voice almost a whisper. Genghis reached down to touch her shoulder and she rose, her face carefully blank. She had none of the wiry strength he had come to expect from his women, and he felt himself becoming aroused as a faint trace of her perfume reached his nostrils.

"I think you are worth more than all the rest of your father's gifts," he said, giving her honor in front of his warriors, though she could not understand the words. Ho Sa began to speak, but Genghis silenced him with a sharp gesture.

He reached out with a sun-darkened hand, marveling at the contrast as he raised her chin so that she had to look at him. He could see her fear and also a flash of disgust as she felt his rough skin touch hers.

"I have made a good bargain, girl. You will bear fine children for me," he said. It was true that they could not be his heirs, but he found himself intoxicated with her. He could hardly keep her in the same ger as Borte and his sons. So fragile a girl would not survive. He would have another ger built for her alone and the children she would have.

He became aware he had been standing in silence for a long time and the tribes were watching his reaction with growing interest. More than a few grinning warriors nudged each other and whispered to their friends. Genghis raised his gaze to the officer standing with Ho Sa. Both men were pale with anger, but when Genghis gestured back to the city, Ho Sa turned as sharply as the others. The officer snapped an order at him and Ho Sa's mouth fell open in surprise.

"You I need, Ho Sa," Genghis told him, delighted with his astonishment. "Your king has given you to me for a year."

Ho Sa drew his mouth into a thin line as he understood. With bitter eyes, he watched the rest of the escort riding back to the city, leaving him there with the shivering girl he had come to give away to wolves.

Genghis turned to face the wind from the east, breathing in the scent of it and imagining the cities of the Chin over the horizon. They had walls he could not break and he would not risk his people again in ignorance.

"Why did you ask for me?" Ho Sa said suddenly, the words wrenched out of him in the silence that Genghis seemed not to feel.

"Perhaps we will make a warrior of you." Genghis seemed to find the idea amusing and slapped his leg.

Ho Sa looked stonily at him until Genghis shrugged.

"You will see."

The camp was noisy with the sound of the gers being dismantled as the tribes made ready to move. As midnight came, only the khan's ger stood untouched on its great cart, lit from within by oil lamps so that it glowed in the darkness and could be seen by all those who settled down in their rugs and furs to sleep under the stars.

Genghis stood over a low table, squinting down at a map. It had been drawn on thick paper and Ho Sa at least could see that it had been copied in haste from Rai Chiang's collection. The king of the Xi Xia was too canny a man to let a map marked with his seal fall into the hands of Emperor Wei of the Chin. Even the lettering was in the Chin language, carefully redone.

Genghis tilted his head one way and then the other as he tried to imagine the lines and drawings of cities as actual places. It was the first real map he had ever seen, though with Ho Sa present, he would not reveal his inexperience.

With a dark finger, Genghis traced along a blue line toward the north.

"This is the great river the scouts reported," he said. He raised his pale eyes to Ho Sa questioningly.

"Huang He," Ho Sa replied. "The Yellow River." He stopped himself then, unwilling to become garrulous in the company of the Mongol generals. They filled the ger: Arslan, Khasar, Kachiun, others he did not know. Ho Sa had recoiled from Kokchu when Genghis had introduced him. The skinny shaman reminded him of the insane beggars of Yinchuan, and he carried a smell with him that seeped into the air until Ho Sa was forced to breathe shallowly.

All those present watched as Genghis drew his finger further north and east along the river until it rested on a tiny symbol and tapped.

"This city here is on the edge of Chin lands," Genghis murmured. Once more he looked to Ho Sa for confirmation and he nodded reluctantly.

"Baotou," Kokchu said, reading the script under the tiny drawing. Ho Sa did not look at the shaman, his gaze held by Genghis as the khan smiled.

"These marks to the north, what are they?" Genghis asked.

"It is a section of the outer wall," Ho Sa replied.

Genghis frowned, puzzled. "I have heard of this thing. The Chin hide from us behind it, do they not?"

Ho Sa repressed his irritation. "They do not. Neither wall was built for you, but to keep separate the kingdoms of the Chin. You have passed through the weaker of the two. You will not pass the inner wall around Yenking. No one ever has."

Genghis grinned at that, before turning back to study the map. Ho Sa stared at him, irritated by the khan's easy confidence.

When he was a boy, Ho Sa had traveled with his father to the Yellow River. The old man had shown him the Chin wall to the north, and even back then, there had been holes in it and sections reduced to rubble. There had been no work done in the decades since. As Genghis traced a line with his finger on the parchment, Ho Sa wondered how the Chin had ever become so careless with their peace. Their outer wall was worthless. He swallowed nervously. Especially as the tribes were already behind it. Xi Xia had been the weak point and the tribes had poured south. Shame burned in him as he studied Genghis, wondering what he was planning.

"Will you attack Baotou?" Ho Sa blurted out without warning.

Genghis shook his head. "And howl outside the gates as I did here? No. I am going home to the Khenti mountains. I will ride the hills of my childhood, fly my eagle, and marry your king's daughter." His fierce expression eased at the thought. "My sons should know the land that birthed me, and they will grow strong there."

Ho Sa looked up from the map in confusion. "Then what is this talk of Baotou? Why am I here?"
