Arthur started walking at fourteen months, which was early without being alarming, which was exactly how he had planned it.
He had given the timing genuine consideration. The temptation, once he had developed sufficient motor control through the combination of magical self-repair and deliberate physical practice he had been running during the night hours, had been to simply walk when he was ready — which would have been somewhere between ten and eleven months, which was significantly early enough to cause the kind of excited commentary from adults that led to other adults paying closer attention. He did not need closer attention. He needed the comfortable medium distance that people maintained from a child who was doing well without doing anything worth discussing.
Fourteen months. Bright. On track. Nothing to see here.
By four years old, the walking had become running — the particular confident running of a child who had spent years having better balance than he let on and could now let it show without explanation. It had also become climbing, specifically the climbing of things his mother had expressed reservations about: the barn roof, the larger of the two oak trees at the field boundary, the stone wall that bordered the new east field, which was nominally not difficult to climb but was six feet high and required a specific approach that Arthur had identified on his second day of knowing the wall existed.
He climbed these things because he was four years old and because his body, freed from the constraints of performed incompetence, wanted to move in the way that healthy children's bodies wanted to move: continuously, experimentally, at the upper limit of what felt possible. He was careful. He did not fall. His mother had stopped trying to prevent the climbing after a period of about three weeks in which it had become apparent to her that the climbing was going to happen regardless and that the energy spent preventing it might be better directed elsewhere.
She had said, on the day she reached this conclusion: 'If you fall and break something, I am not going to feel sorry for you.'
Arthur had said, very seriously: 'I won't fall.'
She had looked at him with the expression she had increasingly developed for conversations with him in which something was being communicated that neither of them was going to address directly, and gone back inside.
He had not fallen. He had also, in one instance involving the barn roof and a late afternoon shadow that Shadow could use as transit, climbed back down significantly faster than he had climbed up, which he was fairly certain she had not seen.

He was a serious child in the way that people described as serious when they meant watchful, when they meant a quality of attention that seemed disproportionate to a four-year-old's ordinary relationship with the world. He sat in corners and observed. He listened to conversations that adults conducted in the assumption that a child his age was not following them, following them completely, filing the relevant details with the meticulous attention of someone who had been building a model of this world from incomplete information since before he could speak.
He was serious. He was also capable of a specific and whole-hearted kind of joy that ambushed him at irregular intervals and that he had stopped trying to prevent because preventing it was both undignified and exhausting.
Clara was the most reliable vector for this ambushing.
She had a gift for physical comedy — the kind that came from a total commitment to the bit, from doing something completely and without self-consciousness, which produced results that were funny in inverse proportion to how seriously she was performing them. Her impression of the headman of Thornwick — a pompous, heavily mustached man whose particular way of walking involved a slight forward lean and a degree of self-importance that had become its own gravitational field — had apparently been in development for six months before Clara unveiled it at the dinner table one evening, and the result was so precisely observed and so completely committed that Arthur had laughed until he actually fell off his chair, which he had never done before and which seemed to him, as it was happening, like a reasonable exchange.
Clara had been delighted by this response. She had filed it away and was already, Arthur was certain, working on a follow-up.
Lyra's stories were a different kind of joy. The wandering knight had now been wandering for two years across an ongoing narrative that Lyra managed with the specific instinct of someone who had discovered that she could hold an audience's attention indefinitely as long as she understood the difference between resolving a plot thread and exhausting it. She resolved nothing. She introduced new complications at a rate carefully calibrated to the attention span of her audience, which nominally was Thomas and Arthur but in practice often also included Clara, who would deny being interested and then quietly appear in the doorway and stay there for the duration.
The knight's current predicament involved a cursed forest, a talking horse who was deeply pessimistic about their chances, and an alliance with a water spirit whose motivations remained unclear and whose reliability was a matter of ongoing debate between the knight and the horse. Arthur had opinions about where the story was going. He kept them to himself. He was four years old and watching his eleven-year-old sister conduct a masterclass in episodic narrative structure and he found this, privately, wonderful.

His family had known about his magic for a year and a half.
The revelation had not been an event that he could have scheduled. He had understood from early in his second year of life that the secret would have a natural expiration — that the gap between what he was and what he was performing would eventually become too wide to maintain without an incident, and that the incident, when it came, would be better if it occurred under conditions he had some influence over rather than conditions entirely outside his control. He had been managing toward a controlled disclosure, the kind where he revealed something small and allowed his family to react before anyone had to decide how much they actually knew.
Thomas had not cooperated with this plan.
It was raining. Arthur had been watching the loft ladder from his position near the window with the automatic attention he gave to any potential hazard in the household — not anxious monitoring, just the background awareness of someone who had long since accepted that keeping the people he loved safe required knowing where they were and what they were doing. Thomas, fifteen, was bringing down winter stores from the loft. He was moving quickly because he was always moving quickly — he had his father's efficiency, had internalized the farm's perpetual logic of tasks to be done before the light changed.
The ladder's second rung from the top had a crack in it that Arthur had identified three weeks prior and had been considering how to address without revealing that he had identified it. He had not yet decided on an approach. He had calculated the probability of the crack becoming a structural failure in the near term as low.
He had not calculated for Thomas moving quickly with his arms full.
The crack gave under the combined weight and momentum. Thomas dropped — not slowly, not with any of the graceful controlled trajectory that a person in the middle of a deliberate action might have — but with the sudden completeness of a fall that had not been anticipated, that the body had not prepared for, that was going to end on the stone floor with the particular physics of someone falling from ten feet up carrying several pounds of preserved vegetable.
Arthur did not think. The calculation happened below thought. Shadow was in the room — Shadow was always nearby when the household was active, another thing that no one had ever noticed — and the shadow between the ladder and the floor was deep and consistent and Shadow filled it in the fraction of a second it took for the decision to form and execute.
Thomas's fall stopped. Not dramatically. It decelerated — the rate of descent suddenly becoming something that was not a fall anymore but a settling, the way a leaf settles rather than drops, and Thomas arrived at the floor standing, slightly stunned, with his armload of preserved vegetables intact, in a column of shadow that had not been there a moment ago and was gone by the time he had processed what had happened.
He looked at the floor where the shadow had been. He looked up at the loft. He looked at Arthur.
Arthur looked back.
He had been in the middle of eating an apple. He was still holding the apple. He looked at his brother with the expression he had prepared for this eventuality and held it steady, which required more effort than the shadow manipulation had.
Thomas said, 'That was you.'
Not a question. Thomas did not ask questions when he was certain. He stated conclusions the way you stated the weather: as observable fact.
Arthur said, 'Please don't tell anyone.'
Thomas looked at him for a long moment. Then he looked at the floor where the shadow had been. Then he picked up the root vegetable that had rolled away during the descent, placed it with the others in his arms, and said, 'All right,' and finished bringing the stores down from the loft as if nothing had happened.
