Isaac looked at Derkhan and Lemuel. Yagharek drew a little closer to them. Isaac looked up and saw that the humans in the corner of the tip were ceaselessly praying to the vast, automated skeleton. As he watched, Isaac saw the construct repairman who had visited his warehouse. The man’s face was a study of fervent devotion. The constructs around them were still and unmoving, all but the five guards behind them, the burliest of the construction models.

Lemuel licked his lips.

“Talk to the man, Isaac,” he hissed. “Don’t be rude . . .”

Isaac opened and closed his mouth.

“Uh . . .” he began. His voice was cold. “Construct Council . . . We’re . . . honoured . . . but we don’t know . . .”

“You know nothing,” said the shaking, bloody figure. “I understand. Be patient and you will understand.” The man backed slowly away from them over the uneven ground. He retreated in the moonlight towards his dark automated master. “I am the Construct Council,” he said, his voice quivering and emotionless. “I was born of random power and virus and chance. My first body lay here in the dump and ran its motor down, discarded because a programme had faltered. As my body lay decomposing the virus circulated in my engines and spontaneously, I found thought.

“I rusted quietly for a year as I organized my new intellect. What started as a burst of self-knowledge became ratiocination and opinion. I self-constructed. I ignored the dustmen all around me in the day as they piled the city debris up in bulwarks around me. When I was prepared I showed myself to the quietest of the men. I printed him a message, told him to bring a construct to me.

“Fearful, he obeyed and connected it to my output as I instructed, by a long and twisting cable. It became my first limb. Slowly it dredged the dump for pieces suitable for a body. I began to self-build, welding and hammering and soldering by night.

“The dustman was in awe. He whispered of me in taverns at night, of a legend, of the viral machine. Rumours and myths were born. One night in the midst of his grandiose lies he found another who had a self-organized construct. A shopping construct whose mechanisms had slipped, whose gears had faltered and who had been reborn with Constructed Intelligence, a thinking thing. A secret that the erstwhile owner could hardly believe.

“My dustman bade his friend bring the construct to me. That night those years ago I met it, another like me. I bade my worshipper open up the analytical engine of that other, my mate, and we connected.

“It was a revelation. Our viral minds connected and our steam-pistoned brains did not double in capacity, but flowered. An exponential blooming. We two became I.
