From the high railing of the instrument platform, Ivara Quill watched Len Vey vanish into the black mouth of the north chimney pipe.
She didn’t cry out. She didn’t shout an order for the boy to turn back, nor did she reach for the emergency alarm wire. In thirty years of mountain surveying, she had watched men make decisions on the high ledges where a rope had frayed or a bridge timber had buckled under a wagon wheel. She knew that when a courier committed his body to a narrow line of retreat. She shouted after him was an indulgence that served only the vanity of the watcher.
The boy had done the arithmetic of the room in three heartbeats.
He had seen that Melli Dorn was ninety seconds from total muscular failure. He had seen that Urel was spitting lung-blood on the floor. And he had understood that the creature in the rafters was an optimization engine that would butcher the workers unless its main legal directive was triggered. By raising his father’s cracked bell and running into the unlit chimney pipes, Len had transformed himself into a solitary bright light of living priority.
He had bought the wheel ninety seconds of grace by offering his own throat as the price of the diversion.
