The train to the northwestern territories took seven hours.
Elias had offered the helicopter. Aria had said seven hours on a train was more useful than ninety minutes in a vehicle where neither of them could work effectively, and since she was correct he had not argued, and they had boarded the early departure from the central station with two operational cases and the specific quality of focused quiet that settled between them when a large thing was approaching and there was still time to prepare.
The northwestern territories were nothing like the metropolitan center. The landscape changed within the first hour — the dense urban reconstruction giving way to secondary cities with more space between buildings, then market towns that had rebuilt around their original footprints rather than outward, then open territory, farmland and forest and the long pre-Gate infrastructure of a region that had always been less interested in height than in breadth.
The mountains appeared in the fourth hour.
They were not dramatic mountains — not the sharp, photogenic peaks of places that had been photographed for centuries. They were old mountains, worn down by time into broad-shouldered, heavily forested ridgelines that ran north to south across the horizon like a sentence in a language too large to read from close range.
Somewhere in those ridgelines, three Gates were becoming one thing.
Elias worked for the first four hours. Operational logistics — the Legion deployment plan for a convergence anchoring was different from anything in his existing tactical library, which meant he was building the framework from first principles using Ymir's pre-System information as a foundation and the Dragon's operational parameters as the structural constraint.
The anchoring, as he understood it from Ymir's concept-memory, was not a fight. It was a sustained presence — a soul weight heavy enough to give the converging dimensional pressure something to organize around rather than continuing to expand outward. The physics of it, translated into System language, produced a requirement that his Domain needed to operate at full Level 2 extension continuously for an estimated six to eight hours while the Dragon's presence handled the large-scale anchoring and his own weight addressed the interior dimensional dynamics.
Six to eight hours of full Domain at Level 2.
His current sustained maximum, tested in the pre-departure exercises, was four hours at full extension before the efficiency degraded to a point that required active management rather than passive maintenance.
He needed to extend that by two hours minimum.
The solution he arrived at, around hour three of the train journey, involved Ymir in a different configuration than the emergency mana contribution during the Dragon engagement. Rather than a burst contribution, he needed the Vassal bond to maintain a continuous low-level feed — enough to offset the Domain's drain without taxing Ymir's reserves and without creating the oscillation effect that burst contributions produced in the mana pool.
He had never attempted sustained Vassal feed during an active Domain.
He added it to the list of things he would be attempting for the first time in the northwestern mountains, which was becoming a longer list than he preferred.
In the fifth hour, Aria finished the oversight council debrief document and closed her case.
She looked out the window at the mountains, which were closer now, the ridgelines developing individual character as the distance reduced. She had a specific way of looking at landscapes — not the aesthetic appreciation of someone who found scenery meaningful, but the operational assessment of someone who was automatically cataloguing terrain features for relevance.
"The convergence site is here," Elias said, sending the cartographic coordinates to her screen.
She looked at them. "Northeast face of the central ridge. Accessible from the valley floor."
"The approach route is clear for the first four kilometers," he said. "The last two will require the Legion to manage the ambient mana pollution — the convergence is already affecting the surrounding space at that range."
"How bad?"
"At current growth rate, uncomfortable for a standard Hunter at two kilometers. Potentially hazardous at one. We will not be operating as standard Hunters."
"No," she agreed. She looked at the coordinates again. "The Dragon."
"Will arrive from its Sovereign Territory through dimensional transit," Elias said. "It does not use Gates. It moves through dimensional space directly."
"When?"
"When I call it through the Covenant," he said. "I am going to wait until we have assessed the interior conditions from the valley floor before I call. The Dragon's arrival will be visible to every detection system in range. I want to have full operational clarity before that happens."
Aria nodded. She was quiet for a moment.
"The three hundred and forty thousand people in the impact zone," she said. "Have they been notified?"
"The northwestern territorial government was briefed by the framework's liaison team this morning," Elias said. "Voluntary relocation advisory is in place for the closest population center — about forty thousand people within forty kilometers of the site. The advisory is framed as a precautionary measure related to Gate activity, which is accurate."
"Not framed as a Dragon is coming."
"Not yet," he said. "When the Dragon arrives, the detection data will be immediate and widespread. The government's communication team has a prepared statement." A pause. "Aria's draft," he added.
She glanced at him. "You had me draft the Dragon's public communication statement."
"You are better at communication architecture than I am," he said.
"You did not tell me that was what I was drafting."
"You would have drafted it differently if I had told you," he said. "The version you wrote assuming it was a standard framework communication event is more useful than the version you would have written knowing it was specifically about a Dragon."
She looked at him for a moment.
"That is extremely Elias of you," she said.
"I take that as confirmation the draft is good."
"The draft is good," she said. "I am reserving my feelings about the methodology."
"Reasonable," he said.
The train continued through the mountain foothills. The light was different here than in the city — cleaner, with less of the ambient mana pollution that twelve permanent Gates within the metropolitan area produced in the surrounding atmosphere. The sky had a quality of unmediated clarity that felt almost unfamiliar.
In the sixth hour, the Legion status indicator showed full regeneration complete. One hundred shadows, all operational.
In the seventh hour, the train reached the northwestern terminus.
The station was a small building that had been rebuilt from something older — stone foundation, newer materials on top, the architectural honesty of infrastructure that was not trying to be anything except what it was. A platform. A roof. A place where trains stopped.
They were the only passengers getting off.
They collected the operational cases. They walked out of the station into the cool mountain air, which was several degrees colder than the city and smelled of pine and granite and the specific cold-weather clarity that existed at elevation.
Aria looked at the mountains.
Elias looked at the valley floor stretching north toward the convergence site.
In the far distance — too far to see directly, but visible as an effect on the landscape — the sky above the central ridge had a different quality than the surrounding sky. A subtle wrongness of color. The visual signature of dimensional instability at scale, the kind that the human eye could not quite articulate but registered as a persistent, low-level wrongness that made extended looking uncomfortable.
"Eleven days," Aria said.
"Ten," Elias said. "The revised model updated again on the train."
She did not respond to this. She picked up her operational case.
They started walking.
