We need to name it," Yssel said.She was at the research table on a Tuesday afternoon, the Root-spring documentation spread before her in the careful arrangement she used when she was working toward a conclusion — the primary measurement records closest, the frequency analysis in the middle band, the historical comparative data at the edges, the pattern of the work visible in the arrangement of its materials. Five years of documentation since the formation's discovery, compiled into a record that had already become a foundational text in Root-Dynamics and that scholars were citing in papers addressing questions the field had not known it needed to ask until the Root-spring gave it the occasion."The formation site," she said. "It needs a formal name for the academic record. We've been using descriptive designations in the working documents — 'the formation in the deep Greywood,' 'the crystallisation site,' 'the Root-spring site.' Those are sufficient for internal documentation. They're

"I will not come next winter," Calder Veth said.He said it at the end of the winter session, which had been three days of archive work and substrate theory review and one long afternoon of Veth walking methodically through the forty-four volumes with the kind of attention that produces not notes but understanding — the absorption of the whole, which was how he read things that mattered to him. He said it without preamble, in the way of someone who has decided what they are going to say and sees no benefit in delay or softening.He was three hundred and fifty years old. He had a preservation bond — the Aeth that maintained the substrate integrity that aging would otherwise degrade, that had kept him what he was for three and a half centuries of precise, methodical, patient work. He had come to the Collegium for the first time eight years ago as an observer, when Kael had found him in the Solmere archive and understood, in the way that sometimes happened, that here was someone who had b

"The echo is gone," Kael said.He said it quietly. He was in the archive on an ordinary Tuesday morning — not a session day, not a Gathering week, just an ordinary morning in late autumn when the Collegium was going about its usual business and the city was going about its usual business and the Root-spring's hum was audible in the substrate half a mile away with the steadiness of something that had been there for years and would be there for years more."When?" Sera asked.She was at her table with the regional correspondence — the western office reports, which she reviewed weekly, the same careful attention she gave to everything she maintained responsibility for. She had looked up when he spoke. She had the quality of giving full attention when he said something that mattered, without making a performance of the attention."Sometime in the night," he said. He looked at his wrist. At the copper lines, which were still there — the fire-bond marks, fully integrated, thirty-seven years

"What is in the hollow?" he asked.He asked it to no one in particular. He was on the east wall of Ashenveil, on the morning of the thirty-eighth year, in the hour before the Collegium woke, watching the Greywood and the spring light coming through the ancient trees at the angle it came at this time of year — low and golden, the kind of light that found the amber of the Root-spring's frequency signature in the substrate and seemed, to his particular perception, to make it visible above the surface too, the amber frequency bleeding upward into the air.The Durnholt Root-spring pulsed. Half a mile east, through the ancient trees, in the place where three old oaks had grown around a common root-platform over centuries of shared growth, the formation that had grown from thirty years of answering the question was warm and present in the substrate. Active and continuing. Still growing — Yssel's measurements showed it still growing, seventeen inches now, the crystallisation process ongoing be

"The Durnholt Root-spring," Tal said, "is not stabilising."They said it at the weekly monitoring review, which Kael had been attending since Yssel left because someone who understood what the data meant needed to be in the room with Tal when Tal looked at it. Yssel had been that person. In her absence, it was Kael, who understood enough to ask the right questions and knew enough to know when Tal's answers required further questions."Define not stabilising," Kael said."A formation site typically reaches a stable frequency equilibrium within two to three years of initial crystallisation," Tal said. They had the measurement charts spread across two tables and were looking at them with the expression of someone who has been looking at something for a long time and has recently noticed that what they are seeing is not what they expected to see. "The Durnholt formation has been in the accelerating phase for six years. It has not plateaued. It has not shown any indication of approaching a
