One day south and east of Cael's forge, in the specific transition between the mountain district's highland character and the deeper interior formation's geology, the fragment changed.
Not the warmth — the warmth had been consistent, directional, south and east, the same since the ledge. What changed was the quality underneath the warmth. The ambient presence of whatever was in the fragment, which had been quiet for the two days of the forging — present, as it was always present, but quiet, not adding anything to the background warmth — suddenly was not quiet.
Not the language below language.
Not the direct communication of the ledge.
Something subtler and more unsettling.
A quality of attention.
Not toward something external. Toward him. The specific quality of something that had been watching his development — had been watching, he understood in the moment he felt it, since the ledge — and was now, for the first time, adding something to the watching. A quality of assessment. Of measurement. As if what he had done in Vera's basement and what he had done during the forging had been observed and had now reached a threshold that warranted a response.
The response was not a message.
The response was a feeling.
Specifically: that he was ready for something he had not been ready for before. Not the anchor point work — he had been building toward that. Something more fundamental. Something in the quality of his connection to the fragment itself, which had been one-directional — his reading of the fragment's warmth — and was now beginning to be something else.
He said nothing to Dain, who was walking beside him with the easy silence of someone who had covered the same ground many times and whose attention was appropriately divided between the route and the ambient resonance reading.
He pressed his right hand to the locket through his coat.
The warmth.
And underneath the warmth, for the first time, a quality that was the fragment receiving him rather than simply being received.
He filed this.
He kept walking.
They camped that night in the interior formation where the surface geology expressed the deep substrate's character most clearly — the specific exposed rock of the highland's eastern edge, the dark stone that carried the void layer's frequency at surface level.
Dain made a fire.
They ate without conversation. The specific silence of two people who had been walking together long enough to have developed a shared understanding of which silences were companionable and which required filling, and who had determined that this one was the former.
Then Dain said: "Your father. The first time he contacted an anchor point. Did Vera tell you what happened?"
"No," Corvin said.
"He was sixteen," Dain said. "Younger than you. He had been training for three years under his own father's instruction. He had the blade, the full training, everything prepared." He paused. "He made contact with the anchor point and he did not emerge for nine hours." Another pause. "His father thought he had lost him. When he finally came out of the contact his father described him as — changed. Not in a frightening way. In the way of someone who had encountered something that had permanently altered their understanding of what they were."
Corvin thought about this.
"What had he encountered?"
"He never fully described it," Dain said. "Not to his father, who told the story to me years later. Not to anyone, as far as I know. He said it was not the kind of thing that translated." He looked at the fire. "He said the anchor point contained the working's original specification — not the theoretical model, not a record of it, the actual living specification. The Lord of the Void's construction as it was on the day it was made. And that encountering the actual living specification of something that old and that precise was—" He paused. "He said it was like hearing a voice you had been told about your entire life and had formed an impression of from the description, and then hearing the voice itself and understanding that the impression had been accurate in its details and completely inadequate to the experience."
Corvin looked at the fire.
He thought about being sixteen and pressing his palms against an anchor point and feeling the working's original specification for the first time.
He thought about what his father had been like at sixteen. Patient. Precise. The qualities Borin had described — present in another person at a similar age, doing a similar thing, in a world where the anchor points had been maintained and the Veil had been intact and the role of Warden had been what it was built to be rather than what it was now.
He thought about himself at seventeen, in a world where the anchor points had been drifting for seventeen years and the Veil was failing and the entities were accelerating and there was no previous generation to emerge from nine hours of contact and describe to.
He thought about the fragment's new quality. The assessment. The threshold reached.
"What did his father do," Corvin said, "when the nine hours passed?"
"Waited," Dain said. "He said afterward that the hardest thing he had ever done was not go in after him. But he understood that the contact required what it required, and that interrupting it would not have helped."
Corvin nodded.
"I may be longer than nine hours," he said.
Dain looked at him steadily.
"I know," he said. "I'll be here."
