"Protect the khan, my son," he said softly. The younger man bowed his head and Murakh placed a hand on his shoulder, leaning forward to touch foreheads for a moment. Without a glance at the shaman who had brought them to the hill, Murakh strode down the slope.

The khan sighed, his mind full of clouds. "Tell them to let the conqueror through," he whispered. Kokchu watched as a bead of sweat hung on his nose and quivered there. "Perhaps he will be merciful with my sons once he has killed me."

Far below, Kokchu saw the bondsman Murakh reach the last knot of defenders. They stood taller in his presence; exhausted, broken men who nonetheless raised their heads and tried not to show they had been afraid. Kokchu heard them calling farewell to one another as they walked with a light step toward the enemy.

At the foot of the hill, Kokchu saw Genghis himself come through the mass of warriors, his armor marbled in blood. Kokchu felt the man's gaze pass over him. He shivered and touched the hilt of his knife. Would Genghis spare a shaman who had drawn it across his own khan's throat? The old man sat with his head bowed, his neck painfully thin. Perhaps such a murder would win Kokchu's life for him, and at that moment, he was desperately afraid of death.

Genghis stared up without moving for a long time, and Kokchu let his hand fall. He did not know this cold warrior who came from nowhere with the dawn sun. Kokchu sat at the side of his khan and watched the last of the Naimans go down to die. He chanted an old protective charm his father had taught him, to turn enemies to his side. It seemed to ease the tension in the old khan to hear the tumbling words.

Murakh had been first warrior to the Naimans and had not fought that day. With an ululating yell, he tore into the lines of Genghis's men without a thought for his defense. The last of the Naimans shouted in his wake, their weariness vanishing. Their arrows sent the men of Genghis spinning, though they rose quickly and snapped the shafts, showing their teeth as they came on. As Murakh killed the first who stood against him, a dozen more pressed him on all sides, making his ribs run red with their blows.

Kokchu continued the chant, his eyes widening as Genghis blew a horn and his men pulled back from the panting Naiman survivors.

Murakh still lived, standing dazed. Kokchu could see Genghis call to him, but he could not hear the words. Murakh shook his head and spat blood on the ground as he raised his sword once more. There were only a few Naimans who still stood, and they were all wounded, their blood running down their legs. They raised their blades, staggering as they did so.

"You have fought well," Genghis shouted. "Surrender to me and I will welcome you at my fires. I will give you honor."

Murakh grinned at him through red teeth. "I spit on Wolf honor," he said.

Genghis sat very still on his pony before finally shrugging and dropping his arm once more. The line surged forward and Murakh and the others were engulfed in the press of stamping, stabbing men.

High on the hill, Kokchu rose to his feet, his chant dying in his throat as Genghis dismounted and began to climb. The battle was over. The dead lay in their hundreds, but thousands more had surrendered. Kokchu did not care what happened to them.

"He is coming," Kokchu said softly, peering down the hill. His stomach cramped and the muscles in his legs shuddered like a horse beset with flies. The man who had brought the tribes of the plains under his banners was walking purposefully upwards, his face without expression. Kokchu could see his armor was battered and more than a few of its metal scales hung by threads. The fight had been hard, but Genghis climbed with his mouth shut, as if the exertion was nothing to him.

"Have my sons survived?" the khan whispered, breaking his stillness. He reached out and took hold of the sleeve of Kokchu's deel.

"They have not," Kokchu said with a sudden surge of bitterness. The hand fell away and the old man slumped. As Kokchu watched, the milky eyes came up once more and there was strength in the way he held himself.

"Then let this Genghis come," the khan said. "What does he matter to me now?"

Kokchu did not respond, unable to tear his gaze from the warrior who climbed the hill. The wind was cold on his neck and he knew he was feeling it more sweetly than ever before. He had seen men faced with death; he had given it to them with the darkest rites, sending their souls spinning away. He saw his own death coming in the steady tread of that man, and for a moment he almost broke and ran. It was not courage that held him there. He was a man of words and spells, more feared amongst the Naimans than his father had ever been. To run was to die, with the certainty of winter coming. He heard the whisper as Murakh's son drew his sword, but took no comfort from it. There was something awe inspiring about the steady gait of the destroyer. Armies had not stopped him. The old khan lifted his head to watch him come, sensing the approach in the same way his sightless eyes could still seek out the sun.

Genghis paused as he reached the three men, gazing at them. He was tall and his skin shone with oil and health. His eyes were wolf-yellow and Kokchu saw no mercy in them. As Kokchu stood frozen, Genghis drew a sword still marked with drying blood. Murakh's son took a pace forward to stand between the two khans. Genghis looked at him with a spark of irritation, and the young man tensed.

"Get down the hill, boy, if you want to live," Genghis said. "I have seen enough of my people die today."

The young warrior shook his head without a word, and Genghis sighed. With a sharp blow, he knocked the sword aside and swept his other hand across, plunging a dagger into the young man's throat. As the life went out of Murakh's son, he fell onto Genghis with open arms. Genghis gave a grunt as he caught the weight and heaved him away. Kokchu watched the body tumble limply down the slope.

Calmly, Genghis wiped his knife and replaced it in a sheath at his waist, his weariness suddenly evident.

"I would have honored the Naimans, if you had joined me," he said.

The old khan stared up at him, his eyes empty. "You have heard my answer," he replied, his voice strong. "Now send me to my sons."

Genghis nodded. His sword came down with apparent slowness. It swept the khan's head from his shoulders and sent it tumbling down the hill. The body hardly jerked at the tug of the blade and only leaned slightly to one side. Kokchu could hear the blood rolling on the rocks as every one of his senses screamed to live. He paled as Genghis turned to him and he spoke in a desperate torrent of words.

"You may not shed the blood of a shaman, lord. You may not. I am a man of power, one who understands power. Strike me and you will find my skin is iron. Instead, let me serve you. Let me proclaim your victory."

"How well did you serve the khan of the Naimans to have brought him here to die?" Genghis replied.

"Did I not bring him far from the battle? I saw you coming in my dreams, lord. I prepared the way for you as best I could. Are you not the future of the tribes? My voice is the voice of the spirits. I stand in water, while you stand on earth and sky. Let me serve you."

Genghis hesitated, his sword perfectly still. The man he faced wore a dark brown deel over a grubby tunic and leggings. It was decorated with patterns of stitching, swirls of purple worn almost black with grease and dirt. The boots Kokchu wore were bound in rope, the sort a man might wear if the last owner had no more use for them.

Yet there was something in the way the eyes burned in the dark face. Genghis remembered how Eeluk of the Wolves had killed his father's shaman. Perhaps Eeluk's fate had been sealed on that bloody day so many years before. Kokchu watched him, waiting for the stroke that would end his life.
