Ashe had not warned them about the first hour.

The path from the compound’s upper gate into the mountain’s lower face was fine — maintained, the footing clear, the gradient manageable. The second section was where it became something else. The maintained path ended at a cairn of stacked dark stone and after that it was simply the mountain, which had opinions about people climbing it that it expressed through increasingly vertical rock and the specific thin cold of altitude that cut through jackets designed for the compound’s outer ring rather than eight hundred meters above it.

Vane climbed and said nothing about this.

Nyx, three steps behind him, said: "You could have mentioned the path stopped."

"I did mention it," Ashe said from above them. She was moving through the rocky section with the ease of someone who had been doing this since childhood and found the difficulty categorically uninteresting. "I said bring the heavy jacket."

"That is not the same information."

"It’s adjacent information. You’re a Justiciar. Deduce."

Nyx looked at the rock face above them. She looked at Vane. "Does she always do this?"

"Yes," Vane said.

"And you just accept it?"

"The alternative is more effort than the climbing."

From above them: "I can hear both of you."

They climbed.

The rock here was the same dark basalt as the compound’s walls, dense with the specific mana saturation of three hundred years of cultivation output absorbed into the mountain’s stone. The Usurper ran passively against it and returned readings that built without completing — not the incomplete frequency of Lancelot, something older and less organized, the ambient accumulation of generations rather than a single architecture. He kept his attention on his footing and let the analysis run in the background.

The gradient eased at the second hour onto a wide ledge that ran along the mountain’s upper face. Ashe was already there, sitting on a flat outcrop with her blade leaning against the rock beside her, eating something from her jacket pocket with the focused attention she gave food after physical exertion.

The view was the eastern territory in every direction.

Korreth at the mountain’s base was a cluster of ancient stone and morning smoke, the market district already running, the compound’s outer ring visible as a rectangle of pale stone above the city. Beyond it the valley road ran east toward Seorak, disappearing into the terrain at the point where the valley’s walls closed together. North, the territory they had not been into yet — rougher ground, the vegetation lower and denser, the ambient field carrying a different quality even from this distance.

"There," Ashe said, pointing north. "The Keran valley runs through there but higher up. When I was fourteen my father sent me through the northern approach rather than the road. It takes an extra day but the terrain is different."

"Different how?" Nyx said. She was standing at the ledge’s edge, not looking at the view the way most people looked at views — with enjoyment or awe — but reading it. The Dreamscape at something above its ambient output, the opal eyes moving across the territory in a pattern that was not aesthetic.

"Older," Ashe said. "The valley road follows the cultivated land. The northern approach goes through ground nobody has claimed. The mana field up there runs on its own logic."

"Yes," Nyx said. "I can read it from here."

She was quiet for a moment, which lasted approximately as long as it took to read something thoroughly.

"There is something in the northern field that was in the archive documents," she said. "The same low register. I read it from the compound wall and thought it might be distance artifacts from the compound’s field. From here it is clearly not." She turned from the ledge. "It’s been in that territory for a long time. Long enough that the terrain has organized itself around it the way terrain organizes around a permanent mana source."

Vane looked north. The Usurper ran against the northern field and returned the same partial analysis — building, not completing, the frequency adjacent to something in its taxonomy without matching anything precisely.

"How long?" he said.

"Longer than the compound," Nyx said. "Longer than the cultivation system’s records. The archive’s documentation of this frequency predates the eastern tradition’s founding records." She sat down on the rock beside Ashe, close enough that the proximity was chosen rather than incidental. "Whatever it is, it has been in that territory since before anyone thought to document it."

"Reassuring," Vane said.

"Extremely," Nyx said. "Sit down. You have been running the Usurper for twenty minutes and I can tell because you keep looking north like it owes you something."

He sat down.

Ashe handed him something from her jacket — the dried mountain spice strips the compound cook made, which he had developed a genuine opinion about over the past weeks. He ate. The morning air at this altitude was clean and very cold and the sun was finding the ledge now, the eastern face of the mountain catching the light directly.

"What exactly does the archive say it is?" Ashe said to Nyx.

"The archive says the eastern tradition’s founders encountered a mana frequency that didn’t originate in the Blessed World’s taxonomy," Nyx said. "They documented thirty-one contact locations across the eastern territory. They stopped documenting because documentation created liability for the people carrying the frequency." She looked north. "The archive doesn’t say what it is. It says what it isn’t."

"And what Ryuken knows?" Ashe said.

"Ryuken knows the location," Vane said. "Two hours from Korreth. He went to the boundary twenty years ago and turned around because what the boundary required was not something he could give."

Ashe was quiet for a moment — running something rather than managing something. "He arranged this entire trip," she said finally. "Nyx finding the archive, the band message, Kaito coming with you. All of it." She looked at the compound below. "And he is sitting in the inner sanctum right now waiting for us to come back down."

"Yes," Vane said.

"And you’re not going to go find him and ask him directly what he knows?"

"Not yet."

She looked at him. "Why not?"

"Because whatever he would tell me now is not the same thing as what I’ll understand after the northern territory." He looked at the ambient field running its low-register frequency in the terrain below. "He has been patient for thirty years. I can be patient for a few more days."

Ashe considered this for a moment. Then she punched him in the arm with the specific impact she used when she agreed with something and was not going to say so.

Nyx watched this exchange with the expression she used when she was confirming something she had already modeled. "Does she always do that instead of agreeing?" she said to Vane.

"Yes."

"And you just accept it?"

"The alternative—"

"Is more effort than the climbing," Nyx finished. The corner of her mouth moved. "You do realize you used the exact same construction twice?"

"It applies twice."

Ashe, without looking at either of them: "The northern approach takes two days if we leave tomorrow at the sixth hour. We should bring the compound cook’s rations rather than stopping at the rest post because the rest post at the northern valley entrance has been running on the same menu for forty years and Kaito has opinions about it that I do not want to sit next to for an entire meal."

"What kind of opinions?" Nyx said.

"Detailed ones. Historical ones. He traced the decline of the menu to a specific supply chain decision made in the third year of the eastern reorganization." She ate the last of the spice strips. "It took one hour and twenty minutes. I timed it."

Nyx looked at Vane. "Were you there for this?"

"I was not there for this," he said.

"You were extremely there for this," Ashe said. "You asked a follow-up question."

"It was a clarifying question."

"It was forty additional minutes."

Nyx looked out at the eastern territory, the opal eyes warm at the edges in the way they were warm when something had genuinely caught her. "I like him," she said simply.

"He grows on you," Ashe said.

"Like something that grows slowly and is very difficult to remove," Vane said.

"Moss," Nyx said.

"I was going to say a tree."

"Moss is more accurate. Pervasive, occupies every surface, and you only notice it once it has been there long enough to be permanent."

Ashe looked at her. Something in her expression did the small real thing it did when someone had said something exactly right. "Yes," she said. "Exactly that."

They sat on the ledge in the morning sun and the territory ran below them in every direction and the northern field carried its low-register frequency in the ambient and the compound below had its lamp burning in the inner sanctum’s high window the way it had been burning since before any of them arrived.

Nyx leaned against Vane’s shoulder with the ease of someone who had finished deciding something and was done performing the distance that preceded the decision. Not a gesture. Just where she was.

Ashe looked at the territory below. The corner of her mouth did the thing it did when something was exactly as it should be and she was not going to make anything of it.

The mountain was cold and the sun was warm and the eastern territory spread out below them, patient and old and entirely indifferent to the three people sitting on its upper face deciding to go further into it.
