The purification treatments were an accident.
Not an accident of carelessness — he had not been careless. They were an accident of thoroughness, the kind that occurred when you were paying close enough attention to something to notice what you hadn't expected to notice.
He had been maintaining Lyra's monthly treatments for almost a year — the ongoing sessions that kept the lung infection suppressed and continued the slow work of repairing the accumulated structural damage. The treatments had become routine in the way that repetitive skilled work becomes routine: not thoughtless, never thoughtless when the work was on his sister's lungs, but flowing, efficient, the focused attention settling into the task without the labored concentration of the early months.
During a session in his fourth year of life — Lyra asleep, Shadow beneath the bed, the healing sense extended in its finest thread — he became aware of something he had not previously attended to. Not in her lungs. In the adjacent tissue, in the cellular environment of the surrounding structures, in the water content of the body itself and the specific mineral profile of that water.
The diagnostic sense had been expanding alongside the healing sense, developing in resolution and range with the same gradual opening that the healing sense had shown. And what it was showing him now, in a level of detail it had not previously had access to, was the specific chemical profile of tissue that had been living for years in a body that was drinking water from an imperfectly clean source, eating food that was nutritionally adequate but not optimal, working in conditions that produced specific categories of inflammatory residue that the body's natural processes could manage but could not fully eliminate.
He had known, abstractly, that the body accumulated impurities. He had read it, in his previous life, in the form of nutrition science and environmental health studies, the specific ways that industrial food supply and polluted water and chronic low-level stress produced measurable changes in cellular function over years and decades. He had known it as information.
He had not previously seen it. Not like this. Not with the specific resolution that the diagnostic sense could now achieve, reading the actual physical state of his sister's tissue at a level of detail that showed him not just what was wrong with the lung infection but everything else — the mineral deposits, the inflammatory markers, the accumulated residue of years of water from a well that was clean by local standards and not clean by the standard of what a body would choose if it could choose.
He held what he was seeing and thought: she is healthier than she was. She is not as healthy as she could be.
He thought: is the same true of everyone else?
He ran the diagnostic sense across the household during the next series of nights, each family member in turn while they slept. The answer was: yes. Varying degrees, varying profiles, varying specific combinations of accumulated impurity. His mother had the particular profile of someone who had been dealing with hard water for the duration of her adult life. His father had the profile of someone whose joints had been working beyond their ideal inflammatory threshold for fifteen years. Thomas had the profile of a growing teenager whose body was managing nutritional demands with what was available, which was not always enough.
And Arthur himself — he ran the diagnostic sense on his own tissue and found what he had expected to find and then found, underneath what he had expected to find, something that surprised him: his own healing sense, running its background maintenance on his body continuously since before he had consciously directed it, had already been addressing most of what he was now seeing in the others. He had been purifying himself without knowing it. His cells were cleaner than anyone else in the household's by a significant margin.
He filed this under: things that explain things, and went back to considering what to do about the rest.

He began with his father because his father's need was the most urgent by the specific measure of long-term structural damage — the joints were the concern, the joints and the circulation, the early accumulation of the kinds of physical wear that in his previous life's medical framework would have been the foundation of the chronic conditions that made old age harder than it needed to be.
He also began with his father because his father was, among the household members, the one whose improvement would be most attributed to explicable causes. A farmer who worked outdoors and slept better in winter than summer and whose physical condition improved slightly was a farmer doing well. No one would ask pointed questions about a farmer doing well.
The nightly sessions with Edric were qualitatively different from the sessions with Lyra. Lyra's work had been surgical — targeted, precise, addressed to a specific condition with a specific mechanism. This was environmental remediation. The diagnostic sense identified the accumulations, the healing sense removed them: the mineral deposits drawn out through the tissue and processed by the body's own elimination pathways over the days following each session, the inflammatory residue cleared from the joint capsules where it had been building for years, the cellular hydration profile corrected toward what it should be rather than what the available water had produced.
He worked slowly. Three sessions a week, alternating areas, never taking more in a single night than the body could comfortably process in the following days. He had learned from the healing work on Lyra that the body needed to participate in its own improvement — needed to be given room to do its part rather than being overwhelmed by a magical intervention that outpaced its natural capacity to adapt.
The changes took six weeks to become visible.
Edric straightened. Not dramatically — not the sudden military posture of a man who has had something corrected, but the gradual ease of someone from whom a constant low-level discomfort has been removed, who is no longer unconsciously arranging themselves around it. He stopped leading with his shoulders. His stride lengthened slightly. He came to dinner one evening and sat down without the small intake of breath that had, Arthur now realized, been so consistent a part of his father's settling-into-a-chair that it had become invisible through familiarity.
His complexion changed. The specific weathered texture of a person who had been working outdoors for decades in conditions that aged skin beyond its years began to ease — not reverse dramatically, not produce the sudden youth that would have required explanation, but soften. The constant slight inflammation that had been the baseline of Edric Voss's skin since before Arthur had been born reduced, and what was underneath it was simply healthier, more itself.
His hair, which had been rough and dry with the specific texture of someone whose body had been directing hydration resources toward higher-priority systems for years, began to settle.
Arthur watched all of this with the particular satisfaction of successful applied work — the satisfaction that was not pride but was related to it, the feeling of an instrument doing what it was made to do.

Mira noticed in the seventh week.
He had been watching for her noticing — had been calculating the approximate timeline of her observation with the same methodical attention he brought to all variables that affected the household's stability. Mira Voss missed very little. The question was not whether she would notice the changes in her husband but when, and whether the when would be before or after the changes had progressed far enough to require either a convincing natural explanation or the truth.
She noticed on a Sunday morning when the light was good — the particular quality of winter sunlight that came in at a low angle through the new glass windows and illuminated the kitchen table with the kind of clarity that was more honest than flattering. Edric was eating breakfast. Mira set a bowl in front of him and then did not move away. She stood at the table and looked at him with the focused attention of someone who has just seen something they weren't expecting and is deciding how seriously to take it.
Edric looked up. 'What?'
'You look different,' she said.
'I've looked the same for thirty years.'
'That,' she said, 'is not true anymore.'
Edric's response — touching his face with one large rough hand in the way of a man who had not been in the habit of examining his own appearance and found the suggestion that he should startling — was to say that he had been sleeping better. Which was true. The removal of the inflammatory burden from his joints had improved his sleep quality in ways that were measurable and real and that he could report with full sincerity, because he had genuinely noticed it even if he did not know the cause.
Mira looked at him for another moment. Then she looked across the kitchen.
At Arthur.
Arthur, who was sitting in his chair eating porridge with the focused attention appropriate to a child engaged with porridge, was aware of the look in the particular way he was aware of most things — completely, with the additional awareness of what it meant.
She knew.
She did not say anything that morning. She was, in this as in most things, methodical — she had seen something, had formed a hypothesis, and was going to confirm the hypothesis before she acted on it. He watched her confirming it over the next four days, tracking the changes in her husband with the attention of someone cataloguing evidence, looking at Arthur at intervals with a gaze that was not quite accusatory and not quite questioning but was something that combined both without fully being either.
On the fifth day she came to find him in the yard.
