Lady Lyarra Stark had not been well since Lyanna's birth.
This was the polite way of saying it. The way Maester Walys said it when he came to check on her each morning with his careful hands and his carefully neutral expression. The way the servants said it to each other in the corridors when they thought she couldn't hear. The way Rickard said it to visitors and bannermen who asked after her health — not well since the birth — as if the words themselves were a ward against anything more serious.
Lyarra had her own way of saying it, which she reserved for the hours between midnight and dawn when the baby had finally gone back to sleep and the fire had burned low and there was no one to perform wellness for.
She was dying.
Not quickly. Not dramatically. But steadily, in the way a candle dies — not extinguished, simply consuming itself until there is nothing left to burn. She could feel it in the persistent cold that had taken up residence in her chest regardless of how many furs were piled on the bed. She could feel it in the way the stairs had become a negotiation and the walk from the bed to the window had become an achievement. She could feel it in the way Rickard looked at her when he thought she wasn't paying attention — that particular quality of careful steadiness that she recognised because she had watched him deploy it in the field when things were going badly and he needed the men to hold.
He was holding. For her, for the children, for Winterfell. Rickard Stark was very good at holding.
She loved him terribly for it and it broke her heart in equal measure.
The morning light came through the window at the particular thin, grey angle that belonged exclusively to the North in late autumn, landing across the foot of the bed where Lyanna lay in her cradle, small and imperious and entirely unaware that anything in the world was less than completely satisfactory. Lyarra watched her daughter breathe — the small, rapid breaths of an infant, chest rising and falling with the extravagant confidence of new life — and felt the complicated knot of emotions that had become her constant companion since the birth.
Love so fierce it was almost indistinguishable from grief.
The door opened and Rickard came in. She could tell from his step before she saw him — she had memorised the sound of him moving through Winterfell over fifteen years of marriage, the particular weight and rhythm of him. His morning step now had something additional in it, a faint undercurrent of preoccupation that she had been tracking for the better part of a week.
"You're thinking loudly again," she said.
He came and sat on the edge of the bed, looked at her with the grey eyes that Ned had inherited precisely and Brandon had received a more turbulent version of. "How are you feeling?"
"I asked first."
His mouth moved in the way it did when he was deciding whether to be amused. He looked at Lyanna in her cradle. "She slept?"
"Eventually." Lyarra studied her husband. "It's the stranger. The one from the godswood."
"He has a name."
"Michael." She had heard it from Brandon, who had provided a highly detailed and somewhat dramatised account of the man's appearance in the godswood, his strange accent, the remarkable fact that he had simply appeared and Lord Rickard had brought him inside. Brandon told stories the way he did everything — at a full run, with enthusiasm and minimal regard for the order of events. "Tell me."
Rickard was quiet for a moment. This was not avoidance — she knew the difference. This was him arranging it properly before he spoke, which he always did with things that mattered.
"He came through the weirwood," he said. "Through an archway. From somewhere else." A pause. "Not another part of the world we know. Somewhere else entirely."
Lyarra looked at him.
"He can do things," Rickard said. "Things that have no natural explanation."
"Magic," she said.
Rickard looked at her with a faint sharpening of attention. "You don't seem surprised."
"I'm a Stark by birth before I was a Stark by marriage," she said. "My grandmother used to say that the blood of the First Men runs closest to the old things in our family. That there are people in the world who carry something in them that others don't." She shifted against her pillows, carefully — movement required care these days. "I always half-believed her."
"He lit a candle without flint or spark," Rickard said.
"Is that all he can do?"
"I don't know the full extent of it." His voice was measured. "He's not forthcoming. But not deceptive either, which is a different thing. He says what is true and stops where he's not ready to go further." A brief pause. "He said he wants to be useful."
"Do you believe him?"
Rickard thought about it in the genuine way he considered things, not the performative way. "Yes," he said, finally. "He has the look of someone who has been without purpose for a long time and has found it again. That's not easy to simulate."
Lyarra looked at the window. The snow from last night still clung to the ledge outside, thin and precise. "I want to meet him."
"Lyarra — "
"I'm ill, Rickard, not an invalid." She gave him the look that had ended this particular argument consistently for fifteen years. "I want to meet the man who came through our heart tree and lit a candle without fire. I think I am owed that much."
----------------------------------------------------------------------------
He came in the late morning, when the light was at its best in the room and Lyarra had had time to arrange herself into something that approximated dignity — hair brushed, back straight, Lyanna fed and sleeping in her cradle. She had told Rickard she wanted to meet the man. She had not specified that she wanted to do it looking like something the cold had half-undone.
The first impression was not what she had expected.
She wasn't certain what she had expected — Brandon's descriptions tended toward the heroic and Ned's were precise but sparse. What she saw was a man of perhaps thirty in appearance, though something about him suggested the appearance was not the whole truth. Dark circles under his eyes, a quality of watchfulness that was not anxious so much as habitual — the kind of watchfulness that had become so automatic it probably no longer felt like effort. He was lean in the way of people who had been through hard times and not entirely recovered from them. His clothing was strange — the fabric and cut were wrong in the same subtle way his accent was wrong, something almost right that was not quite.
He looked, she thought, like a man carrying something very heavy that he had been carrying so long he'd forgotten it was there.
He entered the room and stopped at a respectful distance, and gave her a bow of his head that was not quite the formal bow of Westerosi courtesy but carried the same intent clearly enough.
"Lady Stark," he said. "Thank you for receiving me."
"Thank you for coming," she said. "Sit down, please. I find I dislike speaking to people standing over me."
He sat. Lyanna made a small sound from the cradle and they both looked at her. She subsided. He turned back to Lyarra with an expression she couldn't entirely read — something had moved across his face at the sight of the baby, some complex thing that had come and gone too quickly to catch.
"You've been in the library," Lyarra said.
"Your maester has been tolerating my presence there, yes."
"Walys doesn't tolerate things he disapproves of. He makes it known." She studied him. "He says you ask good questions."
"Questions are all I have at the moment." He looked around the room with the same careful quality of attention she had noticed Rickard noting — cataloguing, assessing, not nosily but out of what appeared to be deep and settled habit. "This is a fine room," he said, and it was not flattery. He sounded like he meant it specifically, as if something about the room pleased him in a way he could point to if asked.
"It faces east," Lyarra said. "The morning light." She paused. "My husband tells me you came from somewhere else. Another world."
"Yes."
"And there is no going back."
"No."
She looked at him steadily. The way she had learned to look at things she needed to assess without flinching. "I'm sorry for that," she said.
Something shifted in his expression. It was small — the faintest movement, as if a muscle had tensed and released somewhere behind his eyes. She suspected it was not something he allowed often.
"Thank you," he said, quietly.
They were quiet for a moment. Lyanna stirred again, made several serious faces at the ceiling, and settled.
"What is your instinct about this place?" Lyarra asked.
He considered it. "It's enduring," he said. "The castle, the people. There's a quality here of — of things that mean to last. It's not something I've felt in a long time." A pause. "It feels, in some ways, more solid than what I left behind."
"The North does that," Lyarra said. "It either breaks people or it makes them permanent." She looked at him carefully. "Which do you think it will do to you?"
He met her eyes. "I have been broken and rebuilt enough times that I suspect the process is finished," he said. "What's left is fairly permanent."
She believed him.
She reached out and picked up the cup of water on the bedside table, drank slowly because Walys had told her to drink slowly. When she set it down she said: "My husband wants to help you. He doesn't say so in those terms — it's not how he says things — but I know him. You interest him, which is not common, and you appeared in our godswood, which he takes seriously, and you want to be useful, which is a language he understands better than most." She folded her hands in her lap. "I am telling you this because I want you to understand what you would be accepting if you stayed."
"What would I be accepting?"
"Winterfell doesn't do things by halves," she said simply. "If you become part of this household you become part of it entirely. The North protects its own and it expects the same in return." Her grey eyes — Brandon had her eyes, she had always thought, the same warmth underneath — held his steadily. "I want to know that you understand that."
Michael was quiet for a moment. Long enough that she knew he was taking the question seriously rather than simply reaching for the accommodating answer.
"I understand it," he said. "And I will not pretend I'm not — " he paused, as if looking for the word — "cautious, about belonging to something again. I have lost everything I belonged to. More than once." He looked at her directly. "But I understand what you're saying. And I am not the kind of man who takes a thing and gives nothing back."
Lyarra looked at him for a long moment.
Then she nodded, once, with the finality of a decision made.
"Good," she said. "Then we understand each other."
----------------------------------------------------------------------------
The broken tower was his suggestion.
Brandon found it for him, technically — or rather, Brandon found him standing in the yard after his meeting with Lady Lyarra, looking up at the structure with the evaluating expression of a man doing calculations, and immediately attached himself to Michael's side with the irrepressible momentum of a seven-year-old who has decided something interesting is happening.
"Nobody goes there," Brandon informed him, following his gaze to the tower. "It's old. Older than the rest. Father says it broke in a storm a long time ago."
"How long ago?"
Brandon shrugged with magnificent vagueness. "Long."
The broken tower sat in the northeast corner of Winterfell's inner yard — a structure that had clearly once been taller, its top sheared off at some point in the castle's long history and never rebuilt, the walls above the break worn smooth by weather. Compared to the rest of Winterfell it looked abandoned and intentionally overlooked, the kind of structure that a practical household learns to step around rather than repair. A thick-trunked tree had grown up against its base, roots pushing at the old stone.
"Is it structurally sound?" Michael asked.
"Maester Walys says don't go in it," Brandon said, which was not an answer to the question he had asked.
Michael asked Rickard about it that evening.
They had developed an informal routine in the nine days since Michael's arrival — Rickard checked in with him in the late evening, often in the library, sometimes in the small receiving room off the main hall, in the manner of a man who had decided to invest attention in something and was doing so methodically. Michael suspected it was also the manner of a man who did not entirely stop assessing things until he had finished assessing them.
"The broken tower," Rickard repeated. He turned his cup in his hands once. "What about it?"
"I'd like to use it," Michael said. "As a workspace. Potentially living quarters as well, if it can be made functional." He paused. "I'll repair it myself. You won't need to put your men to it."
Rickard looked at him with the small specific attention that meant he had registered the implication of this. Michael repairing the tower himself carried obvious significance given what he was.
"It's not in use," Rickard said.
"I know. I wouldn't ask for something that was."
"It's structurally compromised above the second level."
"I'll address that."
Rickard considered it. "What will you do in it?"
"Work," Michael said. "Research. Things that benefit from privacy and the ability to make a certain amount of contained mess." He looked at Rickard steadily. "I don't intend to do anything in it that I wouldn't be willing to show you. But some of what I do requires isolation as a practical matter — not secrecy."
"There's a difference."
"Significant one."
Rickard set down his cup. "I won't lease it to you," he said.
Michael looked at him.
"You're not a tenant," Rickard said. "You're — " he paused, considering the word — "attached to this household. What's Winterfell's is available to you as it would be to anyone with a place here." A beat. "Use the tower. Fix it if you can. I won't charge you for a building I'd otherwise let fall over entirely."
Michael was quiet for a moment. "Thank you," he said, and meant it with a simplicity that required no elaboration.
----------------------------------------------------------------------------
The tower took him twelve days.
He did it properly — not a patching job, not a cosmetic repair. He went through it floor by floor, reading the damage the way the goblin engineering texts had taught him to read structures, finding what was sound and what wasn't, and addressing each problem at its root. There was water damage in the second-floor walls that had been working quietly at the stone for decades. The staircase had three steps that looked intact and weren't. The breach at the top where the storm had sheared the tower off was significant but — he determined after two days of assessment — not beyond what he could work with.
He used magic for what required it and his hands for what didn't.
The servants watched from a distance for the first few days, with the careful peripheral attention of people who have decided to observe something without being caught observing it. By the end of the first week they had mostly stopped pretending, which he took as progress.
Brandon visited every day without exception, providing unsolicited commentary on the work and occasionally useful observations about the castle's history. Ned appeared every second or third day, said little, and watched everything.
By the end of the twelve days the broken tower was not broken anymore.
The top level — where the storm had sheared away the original structure — he rebuilt not as a duplicate of what had been but as something open: a wide circular platform with a low stone wall around the perimeter, accessible from a new hatch in the floor below. The view from the top on a clear day was Winterfell spread below him and the grey Northern landscape rolling out to every horizon, and on the evening he finished it he stood up there with the cold wind in his face and looked at it for a long time.
You're nesting, Seb observed.
I'm securing a functional workspace.
You scrubbed the floors yourself.
Cleanliness is functionally important.
You planted something in the window boxes.
Herbs. For potions work.
Michael.
Seb.
You're nesting, the hat said, with immense satisfaction.
Michael looked out over Winterfell and did not dignify this with a response.
----------------------------------------------------------------------------
He had been thinking about the problem of repayment since the second day.
Not out of obligation — Rickard had not made him feel obligated, which was either great generosity or great political instinct or probably both. But Michael had meant what he had said to Lyarra Stark. He was not a man who took and gave nothing back. He had spent a long time with nothing to offer anyone, and the want of usefulness had been one of the quieter and more persistent griefs of his solitude.
He had something to offer here. The question was what, specifically, would matter most.
He had ruled out anything with an obvious magical signature — not because Rickard would object, but because introducing magic too visibly and too early into a medieval society had consequences that he had read enough history to respect. He had also ruled out anything that required components or infrastructure he didn't have. What he did have were centuries of accumulated knowledge, a talent for observation, and a well-stocked trunk of materials from a world that this one had no equivalent of.
He found the answer, eventually, in the greenhouses.
More specifically: in the seeds.
He had taken everything from the Hogwarts greenhouses in those last months — every seed, every cutting, every specimen of every magical plant he could find, stored under stasis in his trunk. Most of it was, by this world's understanding, extraordinary. But some of it, carefully chosen, was simply practical.
He spent a week in the rebuilt tower reviewing what he had and cross-referencing it against what he had read of the North's climate and agricultural challenges. The North was cold, growing seasons were short, and the periodic hard winters — the kind that lasted years, he had gathered from the histories — were a recurring threat to food security that no amount of political manoeuvring fully addressed. Stark lords managed it by stockpiling and rationing and the grim pragmatic endurance that characterised the North generally. But stockpiles ran out. Rationing eventually hit its limit.
What the North needed, at its most fundamental, was something that could grow in its climate better than what it currently grew.
Michael looked at his seeds.
He began with the greenhouse.
----------------------------------------------------------------------------
He brought Rickard to see it on a morning in late autumn when the first proper snow of the season had settled overnight and the yard was white and still.
The structure itself he had built at the south-facing base of the broken tower — now his tower, he was beginning to think of it, with the particular quiet possessiveness of someone who hasn't owned anything in a very long time. It was modest in size, nothing to look at from the outside: a glass and stone construction that had been the work of a week alongside the tower repairs.
Inside was different.
Inside it was green.
Rickard stopped in the doorway for a moment. Michael watched his face. The lord's expression did the thing it did when he was recalibrating — that careful stillness before the adjustment.
The greenhouse was warm, significantly warmer than the yard outside, the glass catching and holding what thin winter sun there was and supplementing it with several low magical light sources that Michael had installed in the walls, glowing with a steady amber warmth. Along the benches on either side, trays of seedlings in various stages of growth — small, unremarkable-looking things, green and patient.
"What am I looking at?" Rickard asked.
"Several things," Michael said. "Some of it is what you'd expect in any physic garden — medicines, herbs. Useful but not remarkable." He moved to the bench on the left. "This is what I wanted to show you."
He indicated several trays of more robust seedlings — broader leaves, sturdier stems, growing with a vigour that was, even to an untrained eye, somewhat excessive for the season.
"Where I came from," Michael said, "there were plants that had been selectively cultivated over centuries specifically for difficult growing conditions. Cold. Short seasons. Poor soil." He kept his language careful — accurate, but stripped of terminology that would require more explanation than the moment needed. "I have seeds and cuttings of several varieties. These — " he indicated the largest tray — "are a root vegetable. High caloric value. Grows in cold soil that most things can't manage. Short growing season. Stores well." He moved to the next tray. "This is a grain. Frost-resistant. Can be planted and harvested in a window that the North's current crops can't manage." Another tray. "This one is primarily medicinal. It addresses cold lung — the illness that takes the elderly and the very young in hard winters."
Rickard looked at the trays carefully, then at Michael. "These are real."
"They're in front of you," Michael said.
"You have enough to plant?"
"Enough to start. If we plant carefully and harvest for seed as a priority in the first years, we build stock. In five years you'd have enough to distribute to your bannermen. In ten, the North's agricultural picture looks substantially different." He paused. "I can't promise it'll solve every problem. Winters are still winters. But the margin matters."
Rickard was quiet for a long time, looking at the trays of small green things growing in the warmth while snow sat on the ground outside.
"Why?" he asked.
Michael looked at him. "Why what?"
"You could have kept this to yourself," Rickard said. "These plants, whatever they are. You could have grown them quietly and said nothing. Why give this to the North?"
Michael looked at the seedlings for a moment.
"Because you let me through your door without knowing what I was," he said. "Because your son sat across from me in the library and told me that Winterfell was my home now, like it was the simplest thing in the world." He paused. "And because I have spent a very long time being unable to do anything useful for anyone. If I have something to give, I would rather give it than hold it."
Rickard looked at him with the grey eyes that had been measuring him since the godswood, patient and thorough and without any performance of what they were doing.
"Alright," Rickard said.
"Alright?"
"Alright," he said again, simply, and turned to look at the greenhouse with the expression of a man beginning to make plans.
----------------------------------------------------------------------------
That evening Lyarra asked him about the greenhouse.
Rickard had clearly described it to her — she had the look of someone working with a secondhand account and wanting the original. Michael told her about it while she held Lyanna, who was conducting a serious tactile investigation of whatever was within reach of her small fists.
"Grain that grows in frost," Lyarra said. "A root that stores through winter."
"Among other things."
She looked at him over her daughter's head with the same quality of attention she had brought to their first meeting — careful and direct and not unkind. "Do you know what it means to the North? Genuinely to the North, to the smallfolk in the villages, in a hard winter?"
"I have some idea," he said. "I read what the histories had to say about it. And I've seen what hunger does to a people." His voice was even, but something underneath it was not. "I've seen it more than I'd like."
Lyarra was quiet for a moment. Lyanna made a decisive grab for her mother's hair and achieved it. Lyarra extracted herself with the patient dexterity of long practice.
"You know," she said, "when I was a girl, my grandmother told me that the old stories were real. That there were people who came through the weirwood in the old days — " she paused — "visitors, she called them. People from elsewhere who brought things with them. Knowledge. Gifts. Things that the North didn't have before." She looked at him steadily. "She said the old gods sent them when they were needed."
Michael was quiet.
"I'm not saying I believe that," Lyarra said. "I'm saying she did."
"And you?"
She looked down at Lyanna, who had now obtained a fistful of fur and was examining it with intense scientific interest.
"I believe," she said carefully, "that you appeared in our godswood at a time when the North has need of unusual things. And I believe that whatever brought you here, you intend to do good by this place." She looked up at him. "The rest of it I'll leave to the gods to explain."
Michael looked at the woman who was — quietly, matter-of-factly, in the way she seemed to do most things — dying, and holding her daughter, and making space in her household for a stranger from another world, and managing all three with a grace that he suspected she didn't think of as grace at all, just as ordinary living.
He thought of all the people he had failed to save.
He thought of the things that could not be changed.
He thought of the things that might still be.
"I'll do my best," he said. It was not a large promise. But it was a real one.
Lyarra Stark looked at him for a moment with eyes that had the long sight of someone who has thought carefully about time.
"I know you will," she said.
