Among the defenders, there were specialties as precise as the bolts they shot. Yusuf, the crossbowman, was a man who paused before he fired, as if asking each quarrel permission to fly. He could drop a knight from the saddle with a single, surgical breath. By the northern gate, two spearmen overnighted on a ladder of coils—ready to wedge themselves into a breach and hold like a hinge. On the parapet nearest the horizon, a young man called Karim tended the ballista; he was slender and quick, and his bolts sang through the air and split armor like truth through falsehood.

The sun had not yet climbed above the copper dunes when Salim ibn Rasha slipped from the shadow of his tower. For thirty years the stonework of Qasr al-Ahmar had baked under an unending sky, and for thirty years Salim had kept its bowmen ready, its granaries full, and its memories of a single defeat burned into the inside of his skull. That defeat had been at the hands of mercenaries and temperamental trebuchets—machines with more appetite for rock than reason. Tonight, the horizon smelled of iron and strategy. The Crusaders were coming.

When dusk finally softened the city into a wash of ink and oil lamps, Salim walked the ramparts once more. He touched the weathered crenellation where a bolt had once lodged and felt the heat of memory. "We measure by what holds," he murmured to the night. The city answered with the small, steady noise of life—water moving in a channel, a child's laugh caught on the wind, the distant clink of a smith's hammer.
