The far northern expedition left in the spring of the forty-second year.It was not one expedition — it was three teams, moving into the far northern reaches of Aethoria along three different routes, each team carrying the network correspondence infrastructure, the testing centre conversion materials, and Sael's section of the supplement translated into the northern dialects by the two scholars in the network who had the relevant fluency.The teams were not Yssel-sized — not one exceptional person with extraordinary measurement capacity. They were teams of four, each containing a carrier with strong substrate sensitivity, a correspondence-trained network builder, a testing centre conversion specialist, and a stabiliser-variant. Orren's school had produced its first four graduates. All four were on the northern teams."This is how it scales," Mira said, at the council meeting where the expedition was approved. "Not one exceptional person going to one exceptional place. Four teams, going

In the forty-third year, the second stabiliser school opened.It opened in the central territories, not the eastern, because the eastern school was Orren's and the eastern school had graduated twelve students and those students had gone to their own regions and three of them were teaching their own students. The second school was not Orren's. It was run by a graduate of Orren's school — a woman named Tav who was thirty-five, a stabiliser-variant from the central territories who had trained with Orren for two years and had returned to her own region with the curriculum and the document and the practice and the clear intention of establishing what Orren had established in a different place.She wrote to the archive before she opened: "I am establishing the second school. I need the archive's formal recognition, not because the work requires permission but because the recognition allows me to access the network resources that the school will need. I also want to be in the archive record.

In the forty-third year, a child at a testing centre in the far eastern territories — one of the newly converted centres, in a valley that the network had reached six months ago — asked the testing centre administrator: what is in the hollow?The administrator was one of Yssel's trained eastern practitioners. She knew the question and she knew the answer and she gave it: the hollow is the oldest kind of presence. Its name is Potential.The child thought about it."But what is in my hollow?" the child asked.The administrator wrote this question to the Collegium archive, because it was the question she did not have an answer for and she thought the archive might.Kael read the letter and thought about the distinction. What is in the hollow — the general answer, the framework answer. What is in my hollow — the individual question, the question the framework addressed obliquely but never directly.He thought about what was in his hollow.He thought about fire, integrated. He thought about

On the morning of the forty-fourth year of Kael's life, he went to the Durnholt Root-spring.He went the way he always went — alone, before the Collegium woke, through the Greywood in the early light. He went through the paths he had walked for forty-four years, which were still the paths he knew and were also different every time, because the Greywood was not static and he was not static and the same path walked by a different person at a different age produced a different walk.The spring was thirty-three inches across. It had grown in the past year — Tal measured, monthly, and the growth continued, slower now, in the consolidation phase, but continuing. The amber column was visible without substrate sensitivity, a steady four-foot presence above the formation, the colour of deep autumn light.He sat on the root-platform.He held the eastern stone in one hand and the original stone the Warden had given him in the other — the stone from the early years, smooth with forty-four years of

The manuscript arrived at the Collegium archive in the fourth month of the forty-fourth year, in a package that Renn had carried personally from the eastern territories rather than sending it through the courier network. Renn handed the package to Kael at the gate on a clear morning and said: "She wanted it carried, not sent. She said there is a difference.""There is," Kael said."She also said: tell him to read it alone first. She does not want a room's reaction. She wants his."He opened it in the archive at Lysse's desk, which he used now for the kind of reading that required the particular quality of attention that desk seemed to hold after thirty-four years of Lysse's presence at it.The manuscript was titled: Before the Word. A record of what the hollow sounds like when it has not yet been named.It was ninety pages. He read it in one sitting, which took most of the afternoon.Sael had written it first in the eastern dialect and then translated it herself. The translation was pr
