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.
