The maps covered the entire eastern wall.
Not decorative maps — working maps, the specific character of documents that had been consulted regularly over a long period, their edges softened with handling, their surfaces marked with annotations in several different hands and at least three different inks suggesting different periods of addition. The oldest annotations were faded to the particular pale brown of ink that had been drying slowly for decades. The newest were sharp and dark and recent.
Corvin stood in front of them.
Vera stood beside him with her tea and let him look.
He looked for a long time.
The maps showed the kingdom's geography — the coastline, the mountain ranges, the river systems, the road network. Standard survey work, competent, the kind of thing that any archive of sufficient resources would hold. But overlaid on the standard geography, in a hand that was not the original cartographer's, was a second set of markings. Not roads. Not political boundaries. Something else — a network of points connected by lines that followed no road and respected no political boundary, running instead through the landscape's geology, through the mountain ranges and river valleys and coastal formations with the specific logic of something that had been placed according to the land's deep structure rather than its surface use.
"Anchor points," he said.
"Probable anchor points," Vera said. "I want to be precise about what I know and what I am inferring." She moved to the map's left edge. "The pre-founding records give me the anchor point system's general architecture. A network of embedded foundational elements in the geological substrate, placed at specific locations chosen for their geological properties — the specific rock formations that hold the void layer's frequency most stably, that carry the working's resonance at the depth required for long-term maintenance." She traced a line between two marked points. "The records give me the placement logic. The geological conditions that the original founders identified as suitable. I have spent fifteen years applying that logic to the kingdom's surveyed geology and identifying locations that meet the conditions."
"How many?" Corvin said.
"In the kingdom, approximately twelve probable locations," she said. "Globally — I don't have global survey data to work with. The pre-founding records suggest the system is much larger than the kingdom. The kingdom is one region of a global network." She paused. "But the kingdom's twelve are the ones we can address."
"Address," he said.
"The anchor points require maintenance," she said. "Periodic reinforcement of the working's embedded elements by someone carrying the bloodline at sufficient depth. Without maintenance they drift — the specific term the records use for the degradation of an anchor point's operational specification. Seventeen years of drift across all twelve points means—" She paused. "The structural integrity of the Veil in this region is significantly reduced from its original specification."
"How reduced?"
"I don't have a precise measurement." She looked at him steadily. "I have the behavioral evidence. The overflow entities. The frequency of manifestation events has been accelerating for the last five years. Three years ago there were perhaps six confirmed manifestation events in the kingdom per year. Last year there were forty-seven." She paused. "This year, in the first four months alone, there have been thirty-one."
Corvin looked at the map.
Twelve points. A kingdom-wide network. Seventeen years of accumulated drift across all of them. And the rate of consequence accelerating as the drift compounded.
"The lighthouse," he said.
Vera looked at him.
He was looking at the map's coastal section — the northern coast, above Carenfall, where a point was marked on a coastal promontory at the location of, as best he could orient the map against his memory of the journey north, approximately where a lighthouse would be.
"Yes," Vera said. "The lighthouse at the northern coast. One of the twelve. And one of the more degraded, by my assessment — the coastal geology is thinner there, less stable substrate for holding the working's frequency, which means the drift rate is faster under normal conditions and considerably faster under seventeen years without maintenance."
"How did you identify the lighthouse specifically?" he said. "Not the general location — the specific structure."
She was quiet for a moment.
"I visited it," she said. "Seven years ago. I went to the lighthouse on the pretense of a survey commission and I put my hands on its foundation stone and I felt—" She paused. "I don't have your sensitivity. I'm not bloodline. But I have been reading the pre-founding records for fifteen years and I have developed something — not the full gift, nothing like what the records describe for a full bloodline practitioner. But something. A surface sensitivity. The ability to feel when a location has the quality the records describe." She looked at him. "The lighthouse foundation felt like something that had been alive and was now running on the remnant of what it had been. Still present. Still recognizable. But very low."
He looked at the lighthouse point on the map.
One day north of Carenfall on the coastal road.
He looked at the other eleven points. Distributed across the kingdom — the mountains, the river valleys, the coastal regions, the interior plateau.
"To address all twelve," he said, "what does that require?"
"Each anchor point," Vera said carefully, "requires direct contact by a bloodline practitioner at sufficient depth. Sustained contact — the records describe the maintenance procedure as hours of work, not minutes. The practitioner must identify and address each point of drift individually, which requires reading the point's current condition against its original specification." She paused. "The original specification is—" She hesitated. "The original specification is held in the fragment. The fragment carries the working's foundational frequency, which means a practitioner in contact with the fragment is in contact with the reference standard against which drift is measured."
Corvin put his hand inside his coat and felt the locket's warmth.
The reference standard.
He thought about what the basement's stone had given back to him — his projection reflected, the room receiving his output and returning it with a precision that had shown him the shape of his own capacity. He thought about what it might mean to press his palms against an anchor point's foundation stone with the fragment in contact and the working's original frequency available as a reference.
He thought about how much he did not yet know how to do.
"How long?" he said. "To develop sufficient capability to address the anchor points. Realistically."
Vera looked at him.
"I don't know," she said. "The records describe the training period for a Warden heir in the context of a family where the previous generation was alive to teach and the fragment was in active contact from childhood." She paused. "You are starting later, without the previous generation, under time pressure. The fragment's participation in your development may accelerate the process. I don't know by how much." She looked at the map. "What I know is that the entity overflow is accelerating. That Theron's surveillance network is active. That the longer the anchor points remain at current drift levels, the more the Veil's structural integrity degrades and the harder the maintenance work becomes." She met his eyes. "The correct answer is: as fast as you can manage without going faster than the foundation supports."
Corvin looked at the map.
Twelve points. An accelerating problem. A capability he had been developing for one week in a basement in Carenfall.
He looked at the lighthouse.
One day north.
"I need more time in the basement," he said.
"I know," Vera said. "That's why I built one."
