The foothills south of Karveth's Post did not look dangerous, which was precisely the problem with them. They had the gentle, rolling quality of terrain that had been traveled enough times to seem familiar even to people who had never traveled it before — the path was well-worn between the valley settlements, the waypoints were marked by cairns of stacked grey stone at regular intervals, and the occasional traveler they passed on the road moved with the unhurried confidence of people who had made this particular journey often enough that it had stopped requiring thought. It looked, in short, like the kind of road where nothing happened. This made Luc pay closer attention than he might have paid to a road that looked genuinely threatening, because in his experience the situations that caught people off guard were never the ones that announced themselves.

  He had spent three days in Karveth's Post after the posting board, and those three days had produced a clearer picture of the Meridian House situation than he had hoped to build in that time. The representative — a man named Theron Cas, he had learned from the guild office's registration records, which were public and therefore available to anyone patient enough to ask the right questions in the right order — had posted the inquiry six days before their arrival, which meant he had been ahead of them on the road by almost a week. He was methodical, Theron Cas, in the way of people who do their work carefully rather than quickly, and he had asked the right questions in Karveth's Post without drawing attention to the asking, which suggested professional training rather than noble-house improvisation. The fact that he had moved on south before Luc and Sven arrived was, on balance, a useful thing — it meant his current picture of northern travelers was built from six-day-old information, and six days on a road this active was enough time for the picture to become stale.

  What Luc had not been able to determine in three days was whether Theron Cas was reporting to Meridian House acting independently, or to Meridian House acting as proxy for one of the major Noble Houses, or to someone else entirely operating through a Meridian connection as cover. This distinction mattered enormously, because the difference between a mid-tier house operating on its own initiative and a major house operating with plausible deniability was the difference between a manageable complication and a structural threat. He had filed the uncertainty in the category of things to investigate further as information became available, which was the only honest place for it.

  They left Karveth's Post on the fourth morning, before the settlement's market had opened, not because there was particular urgency but because early departure was simply a better habit on roads where knowing who was ahead of you was as important as knowing who was behind. Sven had accepted this without requiring explanation, which was one of the things Luc valued most about him — he understood the difference between knowing why a decision was made and needing to have it explained, and he operated comfortably in the space of the former.

  The road ran south and slightly east, following the valley floor through a series of descents that the locals called the Step Lands — a sequence of plateau edges where the terrain dropped sharply and then leveled before dropping again, each level a slightly warmer and slightly more vegetated version of the one above it. By the third day out of Karveth's Post they had descended enough that the pine forests of the high elevations had given way to a mixed woodland with an unfamiliar density of undergrowth, and the air had acquired the loamy, layered quality of lowland forest rather than the clean cold of the glacier region. Luc ran his Tremor Sense calibration exercises each morning and found the readings required more interpretation than they had on the tundra — lowland soil was more complex in its transmission characteristics, vibrations traveling differently through the varied layers of clay and decomposed vegetation and root systems than through the more homogeneous frozen substrate he had spent his life learning to read.

  "You're doing that thing where your face goes still and you're actually paying attention to everything," Sven said, on the morning of the fourth day, as they walked through a section of road that passed between two hillsides densely wooded enough to reduce visibility to perhaps twenty yards on either side.

  "I'm always paying attention to everything."

  "You're doing it more than usual, then. The extra version."

  "These hills would make a reasonable ambush position if someone were inclined to use them that way," Luc said, which was true, and also told Sven more precisely than "paying extra attention" what the nature of the attention was.

  Sven's posture changed by approximately two percent, in the specific way of someone whose body has received a relevant assessment and filed it. "How far ahead is the next waypoint?"

  You might be reading a stolen copy. Visit Royal Road for the authentic version.

  "About four miles. There's a settlement there — Torven's Bridge, according to the marker we passed yesterday. Large enough to have a stable and a relay post."

  "Anyone behind us?"

  "Two traders with a cart, about half a mile back. They've been there since this morning. Their pace is consistent with the cart's load, not with following us specifically." He paused. "But there's something in the woods on the east side, about thirty yards off the path. It's been pacing us for the last ten minutes. One person, moving carefully, which means either someone skilled at moving through forest or someone who grew up in one."

  Sven processed this in the three-second way he processed things that required action-readiness without immediate action. "Following us or moving parallel by coincidence?"

  "Unclear. The vibration pattern shifts when we shift speed, which suggests awareness of us, but the trajectory hasn't converged on the road, which argues against active following." He kept his voice conversational, his pace unchanged, his body language that of someone having an ordinary discussion about the road ahead. "Keep walking. If it's hostile it'll commit when we reach the open ground before the first bridge crossing — that's the logical point. If it doesn't commit there, it's not hostile."

  "And if it does commit?"

  "Then we find out what we're dealing with and respond accordingly."

  What they were dealing with, as it turned out, was a girl who dropped out of an oak tree directly in front of them at the bridge crossing, landed in a crouch with the practiced ease of someone who had been dropping out of trees for years and had worked out all the technical problems involved, and straightened up to look at them with an expression of frank assessment that was entirely unself-conscious about the dramatic nature of her entry.

  She was perhaps fifteen, slight in the way of people whose physical efficiency left nothing unnecessary, with the dark brown skin and close-cropped hair common to the eastern coastal populations and a coat that had been repaired so many times in so many places that the repairs had become the primary material. A cultivation belt at her waist carried two sealed containers and a small toolkit of the kind that Arcane practitioners used for precise reagent work. Around her left wrist, a copper band etched with the kind of notation system that only made sense to someone who had been taught a specific institutional shorthand. Her eyes were the particular brown-gold of someone whose ancestry had mixed enough different strands that the individual components were no longer separable, and they were, at this specific moment, running a comprehensive assessment of both of them with the speed of someone who has needed to assess situations quickly and has gotten good at it.

  "You felt me in the woods," she said, looking at Luc. Not a question.

  "For about half a mile," he confirmed.

  "Tremor Sense." She tilted her head slightly. "Builder Ant?"

  He said nothing, because confirming his Core Species to a stranger who had been following him through forest seemed premature.

  She appeared to find his silence informative. "I'm not affiliated with Meridian House," she said, which was a specific enough denial to be interesting. "I've been watching their representative since Westholm. He's two days ahead on this road and he's been asking the right questions to find someone who doesn't want to be found, which means either he's very good at his job or he's working from specific prior intelligence." She paused. "I'm Vayne. I'm an Arcane practitioner, Dawnspire second year, on independent research leave, which is a formal designation that means my academy has decided my field work is more valuable than my attendance for the next eight months. I have reasons to go south that have nothing to do with you and everything to do with a material I need for my fifth-form notation work that only occurs in a specific geological formation three weeks south of here." She said all of this with the particular compression of someone who has learned to front-load relevant information because people who don't have the relevant information make worse decisions. "My reasons for stepping out of that tree instead of continuing to pace you in the forest is that you clearly already knew I was there, so the pacing had stopped being useful."

  Sven was looking at her with the expression he wore when he had decided he liked someone and was prepared to say so at the first appropriate opportunity. "You talk fast," he said, with approval rather than criticism.

  "When there's a lot to say," she said, and looked at Luc again. "I'm not asking to travel with you. I'm observing that we're going in the same direction and that a group of three is less remarkable than a group of two or a person alone, and that a person alone on a road where Meridian House is asking questions about unusual-looking northern travelers has a specific vulnerability that a group doesn't have." She looked at him steadily. "You can say no. I'll keep going south regardless."

  Luc looked at her for a moment — the assessment she was doing on him, and the one he was doing on her simultaneously, and the specific quality of the observation she had just made, which was not an argument for traveling together so much as a clear-eyed statement of the relevant strategic facts, leaving the conclusion unstated. He found the structure of it honest in a way that a direct argument for company would not have been.

  "You said you've been watching Theron Cas since Westholm," he said. "How long?"

  "Eight days."

  "And you followed us instead of him."

  "He's not interesting. He's following information. You're the information." She said this with a matter-of-fact quality that suggested she found the distinction obvious rather than clever. "Also he travels faster on this road than two people who are reading every section of it carefully, which means he'll stay ahead regardless of what I do, and staying ahead of someone who's looking for you is more valuable than knowing his exact position."

  Luc looked at Sven briefly. Sven's expression said he had already decided and was waiting for Luc to catch up.

  "We stop at Torven's Bridge for the night," Luc said, and began walking again. "You can decide whether the direction still suits you in the morning."

  Vayne fell into step beside them with the efficiency of someone who had been waiting for exactly that answer and had been ready to move the moment she received it.
