He called Cross from the archive room while Mara was still building the decay rate model.
"The convergence marks," he said when Cross answered. "Your documentation of them across twenty-three years. I need the total count across all sources, including the Archive materials you referenced in the Ledger file."
A pause.
"Why?" Cross said.
"Because the system was built to produce a specific number of convergence marks," Kael said. "The door condition requires that number to be complete. I need to know how close we are."
A longer pause.
"Hold," Cross said.
Kael heard him moving. Heard the sound of a terminal. Heard Cross's measured breathing while he worked.
"Twenty-three years of Veil Office documentation: thirty-one confirmed convergence patterns," Cross said. "Including entities analyzed and marked individuals identified."
"Add the Archive sources," Kael said.
More terminal sounds.
"The Archive's earliest documentation references convergence patterns going back four hundred and twelve years," Cross said. "Total across all sourced documentation: forty-seven."
"Including me," Kael said.
"Including you."
Forty-seven. He thought about that number.
He thought about four hundred years of the system running and producing forty-seven convergence carriers. One every nine years on average.
Each one selected with the specific quality of cognitive architecture the system needed. Each one put through the same process of entry and cost and escalating depth.
Forty-seven over four centuries. "Of those forty-seven, how many are currently alive?" he said.
The pause this time was the longest yet.
"Six," Cross said.
Six. He looked at his mark.
He thought: six. We are the last six. The count is complete or very nearly complete and the owner knows it and that is why the decay is accelerating. The scaffolding is coming down because the door is ready to be opened.
"Cross," he said.
"Yes."
"The four convergence-pattern entities you used the specialized response on over twenty-three years," he said. "They were not threats. They were messengers. The system sent them and you neutralized them."
A very long silence.
"That is a possible interpretation of"
"It is the correct interpretation," Kael said. "The Southgate entity came to read my convergence point. It left when it had read it. The port district entity spent eleven months gathering information.
None of them were threats in the way your operational model classified them." He kept his voice even. "The specialized response killed four system messengers."
The silence from Cross had a different quality now. Not tactical processing. Something older and heavier.
"I did not know what they were," Cross said.
"I know," Kael said. "That is not an accusation. It is information we both need to work with going forward." He paused. "The asset. I need to know what it is." Cross was quiet for a moment.
"Come in tomorrow," he said. "Alone." Kael thought about that. "Mara comes with me," he said.
A pause.
"Mara comes with you," Cross said.
