The fire roared at the centre of the circle. Shadows flickered around it as dark figures leapt and danced with swords. Their robes swirled as they howled over other voices raised in ululating song. Men sat with stringed instruments across their knees, plucking out tunes and rhythms while they stamped their feet.

At the edges of the fire, a line of Mongol warriors knelt bare-chested with their hands bound behind them. As one, they showed the cold face to their triumphant captors. Their officer, Kurkhask, had been beaten savagely in the battle. Blood caked his mouth and his right eye was swollen shut. He had known worse. Kurkhask was proud of the way the others refused to show fear. He watched the dark-skinned desert warriors shouting and chanting to the stars, waving curved blades marked with the blood of men he had known. They were a strange breed, Kurkhask thought, these men who wore their heads bound in many thicknesses of cloth and loose tunics over wide-legged trousers. Most were bearded, so that their mouths were just a red slash in black bristles. As a group, they were taller and more heavily muscled than the largest of the Mongol warriors. They reeked of strange spices and many of the men chewed at dark roots, spitting brown clots on the ground at their feet. Kurkhask hid his distaste for them as they jerked and yelped and danced, building themselves into a frenzy.

The Mongol officer shook his head wearily. He had been too confident, he knew that now. The twenty men Temuge had sent with him were all seasoned warriors, but they were not a raiding party. By trying to protect the carts of gifts and bribes, they had reacted too slowly and been caught. Kurkhask thought back to the months before and knew the peaceful mission had lulled him, made him drop his guard. He and his men had found themselves in a hard land of dizzying mountain passes.
