Chapter 202: Civilian Yam Network
Khulgen set both hands flat on the table and looked at neither Saran nor Batu when he spoke, in the manner of someone organizing their thoughts before releasing them.
"The military relay moves correspondence across the Jochid territory at speed."
He started to explain in an even tone. "Horse stations, messengers swaps, fixed distance between posts, this infrastructure is already built and working."
He kept his pace and did not stop for acknowledgment. "Those roads and approximately the station positions are also used by commercial traffic moving through the territory. Merchants and administrators outside Sarai rely on private couriers for their correspondence, which means variable cost, variable speed, and no accountability when a letter arrives late or doesn’t arrive at all."
The idea started to form itself as he continued, "The existing relay infrastructure can carry civilian correspondence on a second track alongside the military, with different horses, a different log, a different authorization, but on the same stations and the same routes."
He paused for the first time since he had begun. "And every piece of civilian correspondence logged at the stations creates a record. The administration has a secondary view of what flows through the territory’s commercial and private channels without requiring a separate apparatus to collect it."
Saran considered the idea feasibility.
"The fee structure... per message, per weight, or per distance?"
"Per message, tiered by distance."
Khulgen replied immediately. "The specific rates I’ll adjust once the station costs are worked out."
Batu finally commented, "Who maintains the civilian log at the stations, and who has access to it?"
Khulgen answered without hesitation. "The station operators maintain two separate ledgers, one for military and imperial traffic, one for civilian. The civilian ledger goes to Mahmud’s accounts office as the revenue record. A copy goes to the intelligence section in the military district."
He did not elaborate on the last point, and neither Saran nor Batu needed him to.
The copy existed for reference, not for continuous monitoring. The distinction between the two was what made the system functional rather than what would turn every commercial letter into a state surveillance instrument.
Batu said nothing after that.
He looked at the table and then past the table, the way he looked when outward observation had stopped and inward observation had begun.
The Mongol yam in the history he had come from existed for a full century across an empire that covered a third of the known world’s land surface, and in that century it never had a civilian track.
The empire built the fastest communication network on earth and kept it exclusively for military use. Nobody in Khulgen’s position in that history had proposed what Khulgen just proposed, or if they had proposed it, they were not in a position where the proposal had somewhere to go.
Batu could not determine which of those was true in Khulgen’s case, and he sat with the two possibilities for a moment.
Either the original history created different men for this role, people who watched the existing infrastructure and arrived at different conclusions about what it could do, or the influence Batu had on the people working around him was enough to stimulate these kind of ideas.
The two explanations could not be separated.
What a man’s environment created in the people around him could not be cleanly distinguished from what those people would have made on their own.
It did not need to be answered. The practical implication was the same under either explanation.
What Batu could observe was that the idea arrived from inside the system, from someone who understood the infrastructure from the records outward and extended it by logic rather than by importing a concept from somewhere outside his experience.
An idea that arrived that way was more durable than anything Batu could have named and imposed. It had already passed one test before it ever reached the table.
"Then, we will expand the military stations to accommodate a civilian section."
Saran nodded, returning to the practical layer. "A civilian correspondence log facility at each station and a designated civilian horse string."
"Indeed."
Khulgen continued. "The civilian horses are to be a lower tier than the kind used for the military correspondence. The military relay uses the best available animals for speed, but the civilian relay is carrying correspondence between merchants and administrators, not urgent military intelligence. In that case, slower animals are sufficient, and the cost per station is considerably lower than the military side."
Saran thought for a bit, and then gestured to the map on the felt, "The Sarai civilian station sits next to the guild building we just established."
Khulgen confirmed this with a nod.
"The civilian relay needs a receipt system."
Batu intervene in the discussion. "Anyone sending correspondence through the network receives a dated receipt at the origin station, stamped with that station’s mark. When the correspondence is received, a delivery confirmation goes back from the destination to the origin. That way, the sender can verify that their letter reached its destination."
Khulgen looked at the document in front of him. "The current station log format supports a delivery confirmation entry. The origin station records the dispatch and holds space for the confirmation. The rider completing the delivery logs the recipient at the destination station. The origin station closes the record when the return confirmation arrives."
Batu nodded, "Then build it into the station format from the start. Every station, from the first day the civilian track opens."
Saran gathered her notes from the table and set them in order, the motion of a person who had tracked the session’s items and had now reached the end of them.
She glanced at Batu. "The civilian Yam goes to Khulgen’s office to establish the station terms and the fee rates and Mahmud is responsible for the revenue accounts. The intelligence section liaison runs through the military district’s command structure."
She laid her hands flat on the notes.
"That covers everything from planning."
Khulgen was already closing his document case.
Batu stopped them, "Wait."
Both looked at him.
"There’s one more thing," he said.
