"He that hath eyes to see, let him see; he that hath ears to hear, let him hear."— Matthew 13:9
The week before the tournament had a quality to it that I could not entirely account for by any single cause. The castle itself was unchanged. The cold had not relented, the corridors were the same lengths they had always been, the oats at breakfast remained without salt or distinguishing feature of any kind. The timetable ran as it had since January. And yet, walking through the entrance hall on the Monday morning that began the week, the whole place was electrified, with more spellcasting in this short time than the rest of the year combined. It makes you wonder why they didn't have a monthly competition if it gets this much work done.
Thomas had been awake before me, which was unusual as he hadn't done so before. He too was infected with the anxiety that was spreading through everyone else. When I came downstairs he was already in the outer ward, running the footwork sequence in the cold.
The frost on the courtyard flags had been cleared by the house-elves overnight, and his boot marks were clean in the thin rime that had settled on the edges where they had not swept. I could see his breath from the dormitory window. He ran the advance, the lateral, the combined pattern, the full sequence through twice before I had finished dressing. When I came out and stood by the wall, he did not stop.
"How long have you been out here?" I said.
"Since the first bell," he said, not slowing.
The first bell rang at five.
I leaned against the wall and watched him work through the sequence a third time. His footwork was clean, the transitions between patterns not quite seamless but close, the kind of close that another week of drilling could make seamless and that was now not going to get another week. He knew this and had apparently decided to put in whatever time remained before the sun came up over the eastern tower.
"Come in and eat," I said, when he had finished the third sequence.
He looked at the sky, which had gone from black to dark gray, and made a decision. "After the fourth," he said.
And off he goes, running yet again, though what it'll do for him beats me. Yeah, I'm alright. .
At breakfast he appeared with an unsatisfied expression. He applied the warming charm twice to his coat without sitting down first, which suggested his hands were still cold, then sat and loaded his plate with bread and the cold mutton that had been set out from the previous evening's excess.
"Five more minutes would not have helped," I said.
"It might have," he said.
"Sleep would have helped more."
He considered this seriously, as Thomas considered most things related to physical preparation. "Sleep did happen," he said. "From ten to five is seven hours, which is adequate."
"Seven hours and twenty minutes of footwork in freezing weather."
"The cold sharpens the attention," he said, which was the kind of thing Sergeant Pryce had apparently told him and which Thomas now held as established principle.
"Well, I once heard ice baths help in muscle growth and recovery, so you could add that," I advised, with ahint of sadistic pleasure. I know it works but very few can deal with that level of cold. And so I ate my bread and said nothing further. Across the table, Eleanor was reading from a small hand-sewn notebook she kept for Herbology observations, the kind with pages covered in her even, close hand, dates and plant names and measurements filling every line. She had been adding to it since the break. The notebook was almost full.
"What are you looking at?" I asked.
She turned the page and showed me a diagram of a leaf cross-section. "I am trying to determine whether the drying method my aunt uses preserves the oil content better than the method Professor Graves recommends," she said. "The two produce different results, and I want to know why before I discuss it with Graves." She turned the page back. "I have a hypothesis, but I need another sample set before I can say anything with confidence."
"What is the hypothesis?"
"That heat during drying drives off a portion of the volatile compounds that carry the medicinal activity," she said, "and that my aunt's method, which uses lower heat for a longer duration, preserves more of those compounds even if the visual result looks less uniform." She paused. "I would like to develop an ink from plant extracts to mark which samples came from which method, so the comparison stays clear over time."
I considered this. "Plant-based ink," I said.
"The iron gall ink in the school supply is made with oak galls and iron salts," she said. "It is stable and dark. I want something that behaves differently with different extracts, something that carries additional information in its composition beyond the written mark." She looked at the notebook. "I have not worked out the method yet. It is an idea at present."
"Talk to me about it after Wardlaw's Friday session," I said. "There may be a connection to some work I have been doing."
She nodded, marking the page with a strip of folded cloth, and went back to her bread.
Margaret arrived at the table with her coat already on and her Runes notes under her arm, which meant she had reviewed them at the dormitory desk before coming down. She sat, poured water, looked at Thomas's plate, and said: "Thou art eating more than thy portion of mutton."
"It is the last of the cold platter," Thomas said. "It would have gone to the kitchen otherwise."
"That is not how food works," Margaret said, but she said it without heat, a bit grumpy and a tad hangry if I had to wager a guess.
She reviewed the Runes notes through breakfast, which was not unusual, and when I looked at the margin of the top page I could see the tournament timetable written out in the small hand she reserved for information she intended to consult repeatedly. The first and second year bracket was listed with spaces for the names of entrants, most of which she had filled in from observation and what she had heard in the common room. Some spaces had question marks.
"You have filled in the bracket," I said.
"I have filled in what I know," she said. "The question marks are students whose capabilities I have not observed directly." She turned the page. "The third round will be the difficulty."
"Who is in the third round?"
"If the bracket holds," she said, "either Ashmore or a third-year named Peregrine who entered the lower bracket for some reason I have not been able to determine." She looked at the list. "Peregrine is in his third year. His name appears in the second-year and below division, which suggests either a late entry that was placed where space existed, or an age-related exception I am unaware of." She frowned at the bracket. "I shall ask Wardlaw."
"You could ask him now," Thomas said, not looking up from his mutton.
"The enquiry requires the bracket in hand, which I do not have in presentable condition at breakfast," she said, and turned her Runes notes to the next page.
Thomas looked at her notes, looked at his mutton, and returned to the mutton. This was the right decision as I too was diving back into my breakfast.
The morning Charms session covered the extended application of Impulsus Moderatus under divided attention, which was the class having caught up to something I had been working on for two months. Ashford ran it as a paired exercise: one student maintaining a controlled-force application on a suspended object while the other delivered a second instruction mid-application, requiring the first student to modify the magnitude without breaking the continuity of the spell.
The difficulty was that modifying the magnitude required a deliberate refocus of intent, which was the same cognitive resource being used to maintain the first application. The two draws competed. If the student refocused too sharply on the modification, the primary application wavered. If they refocused too lightly, the modification did not take effect cleanly.
I had encountered this problem in the rune carving work. The tool required sustained intent for depth and force while the mind was also guiding the path, which were two separate tracks of attention that could not occupy the same mental space simultaneously. The method I had developed was a rough partition: path guidance was primary, running on most of the available attention, while force and depth ran on a narrower track that had been established through practice to the point where it required less conscious direction. The same principle applied here. Let the primary application settle into an automatic track, then give the modification its own narrow attention.
On the first attempt, Thomas's suspended object dropped eighteen inches while he modified the force level, which was the most extreme result in the class. He looked at the object on the floor, looked at me, and said: "That should not have happened."
"You pulled everything over to the modification," I said. "The primary application lost its track."
He picked up the object, re-cast, and tried again. The second attempt dropped the object four inches, then caught it. The third held steady through the modification with a slight wobble that did not become a drop. He was adjusting within the session, which was the rate of correction I associated with him learning through the body.
Margaret managed the modification in clean sequence on the second attempt, the primary application not wavering. Ashford paused at her station and watched the third attempt, said nothing, and moved on. He said nothing when a result was as expected. He said nothing when a result was better than expected, either, but there was a difference in his silence depending on which it was, and over two years in his class I had developed some facility in reading it.
Eleanor managed it by the fourth attempt. The first three attempts produced the same failure mode: she held the primary application with complete stability but delayed on the modification, timing her refocus with excessive caution until the window the exercise specified had passed. The fourth attempt she committed to the modification without the delay, and it worked.
"Thou dost wait too long," Ashford told her, stopping at her station. "The hesitation before modification is telling thee the conditions need to be perfect before thou canst act. They do not need to be perfect. They need to be sufficient."
She looked at the suspended object. "How doth one know the difference?"
"Practice," he said, which was his answer to most procedural questions, and which was accurate in the way that accurate answers sometimes fail to be satisfying.
On Monday afternoon, after the work assignment had finished and the outer ward was returning to the quiet that the castle's eastern side held in the late afternoon, I walked the seventh-floor corridor with the Disillusionment Charm cast and the north staircase in its stable configuration.
I had been thinking, for several weeks, about the Room in a way I had not approached it before. The temporal notation texts were on one shelf. The workbench configuration was in one room. The practice space was in another.
What I had been considering was this: the Room responded to need. It had demonstrated this across two years of use. If what was needed was something that already existed in the castle rather than something the Room itself created, could the Room show me where it was?
The castle, as Sir Nicholas had said, had opinions. The Room was the most direct expression of those opinions that I had found. The Room of Hidden Things, in the sense of the room where centuries of students had concealed things they did not want discovered, was a known feature of the seventh floor from everything I had read in the texts on the floor below. Students had been coming to this corridor and hiding objects in one configuration or another since the founders built the castle.
What was in that room, accumulated over six hundred years, was a question worth asking. It was especially so since there hasn't been a Riddle or Dumbledore to clear it out of all the old goodies.
I stood in front of the blank wall and thought about it clearly: a collection of discarded and concealed objects, rune-marked materials, tools, written notes, anything of potential use that had been left behind or forgotten over the centuries of the castle's occupation. The specific nature of the need rather than a vague curiosity.
I walked past the wall.
A door appeared. It was wider than the workbench room's door and set in a heavier frame, the iron fittings darker with age, the wood itself a deeper color than the pine of the common room.
I opened it and went in.
The smell reached me first. Old wood, old fabric, the specific dry mustiness of things that have been in an enclosed space without air movement for a very long time. Then my eyes adjusted to the light, which was the same sourceless, even quality as every other room on this floor, and I understood that the room I had entered was not the size I had expected.
It was the size of the outer ward.
Towers of objects filled the space in every direction. Some were actual towers, stacked deliberately enough that they had held for years or decades, furniture balanced on furniture, cases piled on cases, the whole mass rising to heights that the room's impossible ceiling accommodated without apparent difficulty. Others were simply accumulations, piles that had grown by accretion, objects placed on objects without order, the edges of each pile merging into its neighbor until the floor between them was a narrow passage rather than open space.
I stood for a moment and looked at the nearest section, which was close enough to the door to examine without committing to the interior. A writing desk of considerable age, its surface split along one corner. A trunk, brass-fitted, with no visible lock. Three broomsticks in varying states of decay. A set of iron rune-marking tools in a leather roll that had hardened with age but was intact. A wooden box with symbols on three of its four faces that I recognized from the second-year Runes text as an early preservation array.
The iron rune-marking tools went into my coat pocket before I had fully decided to take them. They were usable and they were what I was looking for and I set them to one side of the door for now.
I took out my wand.
Point Me, in its standard application, made the wand act as a compass needle, pointing toward magnetic north. The spell's underlying mechanism was directional orientation through the caster's intent, the wand's tip responding to the direction the caster was focused on locating. Therefore, standard application: locate north. Modified intent: locate a specific category of object.
I had been working through this modification in theory since January, when I had begun thinking about using the Room this way. The modification required replacing the directional anchor of north with the concept of the thing I was seeking, and then holding that concept with enough clarity that the spell could distinguish it from the surrounding noise of thousands of objects.
I held the wand level, thought clearly about runic-marked boards, and cast.
The wand moved. Slowly it rotated toward the southeast section of the room. The tip held its position when I stopped moving, which was a better result than I had expected for a first application.
I went in the direction the wand indicated.
The southeast section was higher than the surrounding area, the objects there stacked in stable columns rather than random piles. Two stacks appeared as I rounded a furniture formation that occupied twenty square feet of floor space. The first stack held mostly cloth, which did not interest me. The second, partially behind the first, held boards.
Rune-marked boards, old enough that the carving had smoothed at the edges from time and handling, the inscriptions still legible if I angled one toward the light. I picked up the first one and looked at it.
The rune sequence was a variant of the two-input junction arrangement I had worked out in the first year's experiment phase, but the containment geometry was different from anything I had attempted. A square boundary rather than a circle, with channel lines running at angles from each corner to a central point where the action rune was placed. I had read about square containment in the text but had not tried it, because the text had noted it was less stable than circular containment in most applications.
The board was old enough that whoever had carved it had worked with knowledge that predated anything in the current Runes curriculum. The channel depths were consistent in a way I could recognize as intentional without knowing the specific tool that had produced them.
I set the board with the iron tools and cast the modified Point Me again, this time focused on written texts rather than boards.
The wand moved to the southwest.
I followed it through two tight passages between furniture and around a pile of what appeared to be laboratory equipment, glass vessels and iron stands in various states of disrepair, and found a section where trunks had been stacked and then, at some point in the past, at least one had been opened and partially emptied. The contents were not in the trunk but on a low surface formed by two other trunks pressed against the wall. Papers. Folded documents. A book with its cover detached.
I examined the papers nearest to hand. Several were lists, inventory records or supply orders, the ink faded to near-illegibility, the Early Modern English of the script different enough from what I heard daily to suggest these were at least a century old. Below those, folded smaller and written in a tighter hand, were two pages of what appeared to be working notes for an enchanting project: symbol layouts, small diagrams, calculations in a notation I recognized as an older form of the arithmancy framework from Professor Wheatley's sessions.
I could not read all of it. The notation had shifted enough between the document's era and the present that several symbols had different values than I was accustomed to, and the author had not included explanatory text, on the assumption that a reader would share their background knowledge. I folded the pages carefully and put them in my coat.
The book with the detached cover was a practical guide to something in the enchanting tradition, the text describing procedures rather than theory. The binding was too damaged to carry without risk of losing pages. I looked at the first chapter, which covered what it called "impressed pattern work," a technique for transferring a runic design from a prepared template to a receiving surface. The method involved a medium between the template and the surface, one that could carry the impression of the pattern and release it under specific conditions.
This was the variable-layer problem from a different angle. Someone had been working on a version of the same question and had written a procedure for it, three or four generations ago at least, judging by the script style.
I stood in the southwest section holding the book and thinking about what to do. The book needed to go somewhere it could be read properly. The papers needed the same. I could not carry everything in one trip.
I took out a piece of blank parchment and made a rough notation of the location within the room, using the door and the furniture landmark near the entrance as reference points, then marked the spot on my notation with an X and wrote impressed pattern work beside it. That would have to do for now.
I cast Accio on the nearest small object that looked potentially useful, a brass disc about the size of my palm with rune marks on one face, aiming the summoning at the disc specifically rather than broadly. The disc came to my hand. The marks on it were an array I did not immediately recognize, though the outer ring was clearly a containment structure.
Two more castings, two more small objects brought to hand: a folded piece of very thick parchment with a preserved edge, as though it had been treated with something to prevent decay, and a small iron weight with a single rune mark on the flat face. The weight was Fehu, which was a source rune in every tradition I had read, though why anyone had put it on a small weight and then left it in this room was a question I could not answer from the object itself.
I walked the room for another hour, using the wand for direction and Accio for small items I identified on sight, moving through three more sections and finding, in a collapsed pile near the north end, a set of carving tools in better condition than the iron set near the door, the handles cracked but the blades intact, wrapped in oiled cloth that had kept the rust off. Beside them, on the floor, a partial manuscript in a language I did not recognize but whose diagram pages were clear enough to follow without the text. The diagrams showed runic circuits of a complexity I had not encountered in the second-year materials, multiple nested containment geometries, with numerical annotations that matched the arithmancy framework closely enough that I thought I could work out the notation with sufficient time.
The partial manuscript went inside my coat with the other papers. The carving tools I set by the door with the iron set and the boards I had taken from the southeast stack.
When I left, I took what would fit in a bag I had not brought. I had been optimistic about planning. I went back to the door, collected the iron tools and the three boards that had interested me most, and went back down to the dormitory, where I set them under the bed in the space I had been using for materials since the first year.
Thomas, reading at the window with the structural Transfiguration book, looked at the boards.
"More wood?" he said.
"Old rune-marked boards," I said. "Found them in the castle."
He looked at the boards for a moment. "Where in the castle?"
"Upper floors," I said, which was accurate.
He appeared to accept this and returned to the book. I made a longer entry in the notebook about the room's contents, what I had taken, where the books and papers were located relative to landmarks I could use to find them again, and what the priority order for future visits should be. The partial manuscript took the highest position, followed by the book on impressed pattern work if it could be moved without losing pages.
Then I reviewed the Runes preparation for tomorrow's session and went to supper.
Eleanor found me after supper on Tuesday, in the gap between the meal's end and the common room's settling-in phase when students were still moving between the hall and the dormitory wings. She fell into step beside me as I was heading back to check on the boards, which I had not yet examined properly in good light.
"Thou didst say to speak to thee about the ink," she said.
"I did," I said. "Come on, then."
We went to the empty classroom on the third floor, the one I had used throughout the first year and still used when the Room was occupied or when the work was simple enough to need no special space. I set one of the old boards on the desk under the candle and looked at the channel carvings properly for the first time.
The containment geometry on the board was a square with diagonal channels from each corner to the center, as I had noticed in the room. The channel depths were consistent, and the edges were cleaner than anything I had produced with the knife in the first year. The time that had smoothed the outer surfaces of the runes had not reached the channel interiors, which were still sharp where the grain ran parallel to the cut direction.
Eleanor sat across from me and opened her observation notebook.
"Plant-based ink," I said. "You want something that varies by composition rather than just marking the page."
"Aye," she said. "If I had two dried samples from two different methods, and I marked them both with ink prepared from each sample's extract, I could compare the inks directly rather than relying on my notes alone."
"The ink would tell you something the sample no longer shows clearly once dried," I said.
"Yes," she said. "A very fresh extract produces one color or consistency. Older or more processed material produces another. If I can stabilize the extract in an ink form, the variation stays visible even after the extract itself has changed."
I had been thinking about this since breakfast, and the connection that had been forming was clearer now than it had been then. The impressed pattern work method in the book I had found in the room used a medium between a template and a surface, a medium that carried the impression and released it under conditions. If that medium could be a liquid preparation rather than a mechanical substance, the principle of the variable layer I had been trying to develop was no longer a decade-long problem.
"What extract are you considering starting with?" I asked.
"Wound-herb," she said. "I have material from my aunt's farm. The leaf oils are the active component. I need a carrier that does not break down the oil but allows it to be diluted enough to write with, and that dries to a stable mark without losing all the volatile components."
"That is a formulation problem," I said. "The Potions knowledge would help, but this is not exactly Potions."
"I know," she said. "That is why I want to discuss it with someone who thinks about preparation rather than recipe." She looked at me directly. "Thou dost think about preparation."
"Yes," I said. "What have you tried already?"
"Nothing yet," she said. "I am at the stage where I have the question and the material but not the method."
I thought about it. The basic problem in stabilizing a plant extract in a writing medium was that most carriers that worked for ink, such as water-based preparations, would dilute the active compounds too far, while oil-based carriers would not dry to a stable mark. The middle ground was something that would bind the extract, allow it to spread when wet, and hold when dry without losing the compound entirely.
The Ligatura Solutio that Thorne had covered in January was a binding medium for magical components specifically. The principle underlying it, that a primed medium could hold what was applied to it without destroying its properties, was what Eleanor was looking for in a plant-extract context. The challenge was that Ligatura Solutio was a Potions preparation well beyond second-year capability, and the plant extract she was working with was not a magical component in the technical sense.
"There is a simpler version of what you are describing," I said. "It would not be a true Ligatura preparation, but a comparable effect for organic materials. I want to look at something before I give you a specific answer."
She nodded. "When?"
"After the tournament," I said. "I cannot give the problem proper time this week."
She accepted this without objection. For Eleanor, this was also how good things were made: by waiting until the attention required was fully available rather than giving a problem partial work when partial work was the wrong proportion.
"The instrument," she said. "The capacity-measuring disc. I showed my aunt."
"What did she say?"
"She said it was the most interesting thing she had seen in twenty years, and that she wanted to know whether it could be adapted for measuring the potency of medicinal plant preparations." She turned the observation notebook to a page near the back where she had written her aunt's comments in a different hand, or perhaps a different mood, the writing more hurried than her usual. "She has been preparing and testing herbal remedies for thirty years. She said she can tell by the result whether a preparation worked, but not by the preparation itself whether it will work before application. A measurement that could indicate potency before use would be of significant value."
I looked at the page. The question her aunt had framed was clean: a preparation that worked was already known to work by its outcome. What she wanted was a way to know before the outcome. That's actually something which could sell and become a household item, especially for potions. Let's add it to the list of things to do, after my two main projects of course.
"That is a different problem from the capacity disc," I said. "The disc measures magical output from a casting. What your aunt wants measures magical concentration. The principle of proportional response is the same, but the mechanism needs to be different."
"I thought as much," she said. "I told her I would raise it with someone who understood both sides."
"Tell her I am thinking about it," I said. "After the tournament."
Eleanor closed the notebook. She looked at the old board on the desk. "The channel marks," she said. "They are older than the ones thou dost carve."
"By at least a century, I think," I said. "The smoothing on the outer surface is from age."
She turned the board over and examined the back face. "There is no circuit on this side," she said. "Only a few marks near the edge."
"Maker's marks, possibly," I said. "Or a note about the circuit on the other side. I cannot read them yet."
She set the board down. "Where did thou find it?"
"In the castle," I said, which was the same answer I had given Thomas. It satisfied her in the same way, which was to say it did not fully satisfy her but she decided the inquiry had reached its natural limit for the evening.
She said goodnight and went back to the dormitory, and I sat for another hour with the board and the candle and the notebook, copying the channel geometry and the maker's marks for later analysis.
On Wednesday morning, Gifford appeared in the outer ward during the between-lesson gap to announce the caravan.
He said it the same way he said everything, which was without preface or decoration: the traveling merchants had sent word from the village; they would arrive Thursday morning and remain through Friday. Students assigned to work duty should expect adjusted schedules on those days. Access to the wagon inspection would be midday Thursday, as in the previous year.
Thomas, who was standing at the practice yard wall watching Sergeant Pryce's early-morning drill, heard this and immediately turned to me. "Wood and tools," he said.
"I know," I said.
"Thou wert running low on the good boxwood."
"I am aware."
"And the tool oil ran out in February," he said.
"Thomas," I said, "I have been planning this purchase since January."
He looked at me. "Thou hast not said so."
"I was waiting for the caravan to arrive before discussing it," I said. "There is little point in discussing a purchase you cannot make until the thing is there to be purchased."
He appeared to find this reasonable in a way that also slightly annoyed him, in the way that sensible reasoning sometimes annoyed Thomas when he had wanted to contribute a useful observation and found the observation had been made privately some months earlier. He turned back to the drill. "What else?" he said.
"Metal goods," I said. "Writing materials. Some specific items."
"What specific items?"
"A small gift, possibly," I said. "Depending on what they carry."
He looked at me sideways. "For whom?"
"I have not decided yet," I said, which was true in the sense that I had not decided the final list, though I had a working draft in the notebook since February.
He accepted this and went back to watching the drill. Pryce was working two of the younger guards through a footwork pattern that bore some resemblance to the sequences Wardlaw had been teaching in the dueling class, and Thomas was watching with the attention he gave to anything that had tactical application, his eyes on the lead foot rather than the wand hand, which was the thing a person watched when they were thinking about what the opponent was about to do rather than what they were currently doing.
The caravan came in on Thursday before the first lesson.
I heard the wagons in the outer ward from the dormitory window during the early prayer, the creak and grinding of iron wheels on the cleared stone path, the sounds of large animals in an enclosed space. By the time I came downstairs, the wagons had been positioned along the inner wall of the outer ward and the drivers were unhitching the horses with the efficiency of people who had done this particular journey at the end of winter for several years and knew exactly how long each part of it took.
Owen Thatcher was directing the positioning from the gate. He saw me crossing the ward and gave the brief acknowledgment nod he used for students he recognized as not likely to create a problem, which was about twelve of us in the whole school.
The work assignment that Thursday had been adjusted to loading and unloading on behalf of the school's exchange goods, which in practical terms meant four of us carrying bolts of cloth and sacks of preserved herbs from the inner storage building to the wagon designated for trade goods, and then helping to bring several large crates from a different wagon to the same storage building. The crates held metal fittings, preserved ingredients for the Potions stores, and a quantity of dried materials that Mistress Hogg, who appeared in the outer ward for approximately eleven minutes, inspected with the focused attention of someone who had given a specific order and was verifying its execution before returning to the kitchen garden.
The crates were heavy. George and I managed the largest one between us, the kind of weight where conversation was impractical for the duration of the carry, which was perhaps thirty yards from the wagon to the storage building door. By the third crate my shoulders and back had found the familiar steady ache of load-bearing work, the kind that settled into a rhythm rather than growing sharper.
Thomas, on the other end of a different crate with Perkin, was not suffering from the same issue. The summer with the cattle had apparently involved considerably more lifting than I had been led to believe, and the eight months of work assignments since September had been consistent. He carried his half without visible difficulty, which made Perkin, who was carrying his half with visible effort and determination, look less like he was struggling and more like he was studying what adequate looked like, in case he needed to produce it himself under pressure.
Midday brought the open access.
The merchant who managed the wood and tools wagon was a short, broad-shouldered woman of about fifty with ink stains on three fingers of her right hand, which I noticed because it was an unusual thing to observe on someone who primarily sold wood. She had been here the previous two years. She remembered my face from September's caravan, and when I stepped up to the tailgate of the wagon she said, without preamble: "The boxwood, the close-grained ash, or something else?"
"All three," I said. "Small quantities. And I want to see the metal tools."
She indicated a section of the wagon with the familiarity of someone who had organized this space specifically for the kind of buyer who came with a list. The metal tools were in a fitted case, two rows of implements in slots cut to their shapes. Chisels in graduated sizes. Gouges. An awl with a handle of turned wood, newer than the others. And, in the bottom row, a set of scribing tools, pointed metal instruments for marking lines on a surface before cutting.
I examined the scribing tools. The points were finer than anything in the castle's carpentry supply, the kind of precision that came from forging for a specific purpose rather than general use. I thought about the carving tool I had been running since February, the levitated pen-nib approach, and about the work I would eventually do on smaller substrates where the current tool's precision would not be sufficient.
I bought one scriber, two of the smaller chisels, and the boxwood blocks in three sizes. The ash I left on the wagon, since the work I was doing did not require ash's particular quality of consistent fine grain, and the price was not reasonable for a material I did not currently need.
Then I went to the writing materials wagon.
This was managed by the same ink-stained merchant who had been at the previous caravan, the thin man with the close-cut beard who organized his wagon by material type rather than price. Ink in the left section, paper and parchment in the center, prepared materials and compounds on the right. He had added a fourth section since the last visit, a small set of shelves at the rear of the wagon that held sealed jars.
"What are those?" I said, pointing at the jars.
"Gall extract, oak and iron, concentrated," he said. "For scribes who prepare their own ink. Also tannic acid preparation from sumac, which doth produce a different quality of mark on rougher surfaces." He took one of the jars down. "And a prepared iron mordant, which fixeth colorfast dyes to fabric but hath secondary applications in certain preparatory work." He set the jar on the tailgate. "A second-year wizard of thy apparent interests is not the usual buyer for these, but then again the usual buyers do not often come to me in Scotland in March."
"The gall extract and the iron mordant," I said. "How concentrated is the gall extract?"
"Ten parts water to one part extract to produce standard writing ink," he said. "At five to one, thou wilt get a mark dark enough to damage the pen in time." He held up the jar. "At one to one, thou art into preparatory chemistry rather than ink-making."
I bought both jars. I also bought a paper of very fine parchment, the kind used for detailed instrument work rather than ordinary writing, and a quantity of fresh writing reeds that were better quality than the school's supply. The reeds were thin and consistent, the tips not yet cut, which meant they could be trimmed to whatever point width the work required.
At the textile wagon I bought a length of plain linen, very tightly woven, which was not on my original list but was the kind of material that would be useful for fine-work preparation surfaces, specifically for cases where wood was too inflexible and cloth needed to hold a mark precisely. I had no specific application for it yet. The engineer's habit of acquiring useful materials before the need was fully defined had served me before.
At the general goods wagon I spent a few minutes looking before I found what I wanted. The merchant there had a tray of miscellaneous small items near the tailgate: buttons, needles, a set of small brass weights that appeared to be for a balance scale, and, in the corner of the tray, a small round mirror in a plain frame, the glass thicker at the edge than the center in the way of old glass, which gave it a slight distortion at the periphery but a clear view at the center. The mirror was old and used and not expensive.
I bought it for Eleanor, for the plant-comparison work she had described. A visual record of ink samples on a small surface, examined over time with consistent reference, needed a flat and portable reflective surface. The mirror was about the right size for the purpose.
Margaret appeared at my elbow while I was wrapping the mirror in the paper I had bought from the writing materials merchant.
"That is not for the rune work," she said.
"No," I said. "For Eleanor's plant extract project."
She looked at the wrapped mirror. "The ink idea," she said.
"Yes."
"She spoke to me about it this morning at breakfast," she said. "She is working out whether the volatile compounds in the dried herbs can be stabilized in a writing medium." She looked at the paper wrapping. "She did not mention that thou wert involved."
"She mentioned it to me Tuesday," I said. "I told her we would discuss it after the tournament."
"Aye," she said. She looked at the merchant's tray, then at the wrapped mirror. "I have two shillings," she said. "Is there anything on that tray that would be of use to Thomas?"
I looked at the tray. The brass weights were the kind of object Thomas would find interesting in a purely technical sense, and the heaviest of the set was about the right mass for the kind of weighted practice that Pryce had apparently been incorporating into the footwork sessions, based on what Thomas had described in letters from the summer. I pointed at the weights.
"For grip strength and wrist stability under load," I said. "Pryce uses this method."
Having bought the weights, we walked back across the outer ward with our parcels. The caravan merchants were busy with several groups of older students who had descended on the book and equipment wagons, the interest in the caravan from upper years always running higher than from first and second years because upper years had more wages saved and more specific needs from seven years of narrowing focus. Several sixth-year students were in a conversation with the writing materials merchant that appeared to involve a significant quantity of parchment and some negotiation over price that I was fairly sure the merchant was winning.
Thomas was at the tool wagon. He was examining the awl with the turned handle with the attention of someone deciding whether to buy a thing, which meant he was going to buy it. He had been at that wagon for at least twenty minutes, based on when I had left it and when I had seen him here on the way to the textile wagon. The merchant had the expression of someone who had answered several questions and was prepared to answer several more.
When he noticed me and Margaret passing, he called out: "Dost thou know what turned walnut handle doth indicate about the quality of the tool?"
"That someone chose it," I said, without stopping.
He turned back to the merchant. I heard him say, in Early Modern English: "I shall take the awl and the small gouge."
Margaret, beside me, said: "He has been there the entire midday period."
"He makes deliberate purchases," I said.
"He makes detailed ones," she said. "The outcome is similar but the path is different."
We went inside. The corridor off the outer ward was warmer than the ward itself, the stone having absorbed the midday's modest warmth and the cold not yet having overtaken it. I shifted the boxwood blocks under my arm and thought about the partial manuscript in my coat, which I had not mentioned to anyone.
Friday's consultation with Wardlaw was the last before the tournament.
He had set up the practice room with the chalk marks for competitive distance rather than the practice distance, which was two feet further than the standard exercise spacing and required the force application spells to carry the additional interval without losing accuracy. Three students had come to the consultation: myself, Clare from third year, and a first-year named Perkin who had entered the lower bracket with, as Margaret had noted, no obvious explanation.
Perkin was small and young-looking even for his actual age, which meant he drew people's attention in a specific way in competitive contexts: as someone who appeared to be a soft target. This impression lasted until the first exchange. He had been training, it turned out, since before arriving at Hogwarts, the son of a dueling-focused family whose older children had all competed. He cast with a stillness that reminded me of Eleanor and an economy of motion that reminded me of no one I had observed directly.
Wardlaw ran the session at competition pace from the first exchange, which meant no pause between rounds, which meant the attention had to remain fully engaged for the full duration rather than recovering in the interval that practice usually allowed. I had asked for this specifically. He had agreed without comment.
The competition pace revealed something that the practice pace had not: my sensing circuit's information was more useful when there was no time to think about it. At practice pace, I had sometimes tried to analyze what the sensing awareness was telling me before acting on it, which introduced a delay that the competition pace removed. At competition pace, the awareness went directly to the response without the analytical middle step, because there was no time for the middle step. This was better. The circuit was not providing information to be thought about; it was narrowing the window before the thinking started.
Three exchanges with Perkin, at competition pace. I won two and lost one. The loss was the third exchange, when he used a modified direction of approach that I had not seen in any of the practice sessions and which required me to rethink the counter mid-execution, which at competition pace was too slow by a fraction.
Wardlaw stopped the session after the third exchange and told us both to consider what the third exchange had shown us. He said it the way he said everything useful, which was without elaboration, expecting us to supply the analysis ourselves.
What it had shown me was that the sensing awareness was not universal. It gave me information about when a spell was being prepared and in what general direction it was aimed. It did not give me information about modified approach directions, which were physical rather than magical in nature. Perkin had moved three steps to the right before casting, which changed the geometry of the exchange in a way the circuit did not detect. I had relied on the circuit for directional information without accounting for the possibility that the direction of the physical body and the direction of the spell were not going to be the same thing.
Saturday's work assignment was light, the reduced schedule that preceded major school events. I cleared the frost-heaved stone along the east outer wall for two hours, the same maintenance work I had done in January, the same iron-shod mallet and the same long scraper and the same wheelbarrow with the improved wheel. The work had become mechanical enough that I could do it and think about other things simultaneously, which was either a sign of familiarity or of diminished attention and I preferred to believe the former.
The old boards from the room were in my notebook from Wednesday's examination. Three boards, three different circuit configurations, none of which were in the current second-year Runes text and one of which I was fairly sure predated the current text's tradition by at least two generations. The containment geometries were variations on the square boundary I had read about but not attempted, and the channel angles within the square were distinct from the textbook descriptions of square containment in ways I could not yet evaluate because I had not tried them.
I would try them after the tournament.
The partial manuscript was also in the notebook, transcribed from the copies I had made, along with a running glossary of the notation symbols I had been able to identify so far. The notation was older than the temporal notation volumes in the Room's library shelf, the symbols carrying a different weight distribution in their forms, the vertical strokes heavier than the current standard, the horizontal strokes lighter. A copyist error in the original or a deliberate stylistic choice I could not determine from two pages.
That would also wait.
What would not wait was the tournament, which was in one day, and which required whatever remaining preparation could reasonably be accomplished between now and tomorrow morning.
I scraped ice and thought about the leading shoulder and the weight shift in the foot and the gap between the physical direction of the body and the magical direction of the cast, and about Perkin's third-exchange approach and what I would do differently if it happened again. The wheelbarrow went to the pile and came back empty three times. The frost damage along the east wall was minor compared to January's, which was the one advantage that March offered over the earlier winter months.
George worked the adjacent section. We did not talk much, which was the usual arrangement for this particular work.
At midday, Croft came out to check the drainage stakes along the outer boundary, which had been showing the first signs of the frost response he had described in the previous summer. Three stakes were glowing amber at the mid-point marks when I carried the wheelbarrow past the eastern stake line, the glow moving in the slow pulse I had seen in August, the channel marks reading the condition and adjusting the flow. The sight was still remarkable, and I had been watching it across eight months of stake surveys.
I set the wheelbarrow down for a moment and looked at the three glowing stakes. The channel marks at the mid-point were the moisture-condition indicators, the ones that read the soil state and compared it to the threshold values the original builders had set. Whatever those builders had known about the specific conditions of this field in March, they had been accurate enough that the system was still working to specification in the seventh year of my observation of it.
Croft glanced up from his stake-checking. "The northeast corner again," he said.
"Always the northeast corner," I said.
"The soil composition changes at that junction," he said. "The stakes were calibrated for a more uniform composition. I have been meaning to re-cut the channel depth on stakes twelve through fifteen since November." He made a note in his survey book. "After the tournament, I will attend to it."
"I can take the measurements again if you need them," I said.
He looked at the stake line, then at me. "After the tournament," he said again, with the specific emphasis of someone who was telling me to focus on the near-term before the longer-term.
I picked up the wheelbarrow and went back to the east wall.
Eleanor brought the mirror to supper on Saturday evening and set it on the table in front of the space where her observation notebook usually sat.
"Thank thee," she said, when I sat down across from her. "It is the right size."
"I thought so," I said.
Thomas looked at the mirror, then at me. "When did thou buy a mirror?" he said.
"At the caravan," I said.
He considered this. "Is it for the plant work?"
"Yes," Eleanor said. "I shall use it to examine ink samples at consistent magnification."
Thomas nodded with the expression of someone who had followed this to its conclusion and found the conclusion reasonable. He served himself bread and the evening's soup, which was a heavy root vegetable broth, the kind the kitchen produced when the temperature outside warranted something substantial.
Margaret set the brass weights on the table in front of Thomas without explanation.
He looked at them. He picked one up and turned it in his hand. "For grip," he said.
"And wrist stability," Margaret said. "Under load."
He tried the weight in his wrist, the small isometric tension that the practice Pryce had incorporated, then set it down. He looked at Margaret. "Thank thee," he said, with the genuine simplicity he used when something had landed precisely where it was needed.
She went back to her soup.
We ate without much conversation, the specific quiet of a table where four people are thinking about the same thing from four different angles and have run out of new things to say about it. The fire in the Great Hall's far hearth was built high, the evening cold outside pressing through the high windows at the top of the hall, the sky beyond them dark and clear in the way of a sharp March night.
After supper I went to the common room, said the evening prayer in the chair near the fire, and reviewed the tournament bracket in the notebook. Margaret's notation, which she had shared with me on Thursday, had been accurate in all the respects I could verify. The first round would be Birch or myself, depending on the draw. The second round, whichever of us advanced, would face whoever came through the upper half of the second-year bracket. The third round, if I reached it, would be the difficulty she had identified.
I had one day and the tournament began the morning after.
I closed the notebook.
Thomas was at the common room table with a parchment, running footwork diagrams in ink, the patterns laid out in a notation he had developed himself over the past six months, arrows and position marks that meant something specific to him and would be incomprehensible to anyone else. He had three variations drawn out and was comparing them with the focused attention he brought to things he had decided to get right.
Eleanor was at the window with the observation notebook, making an entry in the small, close hand she used for the most detailed sections.
Margaret was mending, which she had been doing every Saturday evening since September of the first year, the basket on her knee and the needle moving in the steady small rhythm of practiced work.
I sat in the chair for a while and did not pick up anything to read, which was unusual enough that Thomas looked up twice in ten minutes to check that nothing was wrong. Both times I appeared to be sitting in the chair without obvious cause, and both times he returned to his footwork diagrams without comment.
There were one hundred and eight hours from the beginning of the first year to now, if you counted the hours I had spent in the outer ward and the third-floor classroom and the Room on the seventh floor and the field in summer and the dormitory and the kitchen and the common room and the owlery and the wall walk above the hillside on a night two years ago that I preferred not to revisit in too much detail. More than that, of course, the actual count was years of hours. The rounding was an engineer's simplification that came from being tired at the end of a long week.
What those hours had produced was sitting in the room in the visible form of Thomas's footwork diagrams and Eleanor's observation notebook and Margaret's mending basket and the old boards under my bed and the boxwood blocks on the shelf and the tools in the leather roll. The invisible form was everything else: the timing of the counter, the sensing awareness, the twenty-one second warming token, the clean corners on the channel geometry, the partial manuscript in the notebook waiting for after the tournament.
The tournament was tomorrow.
I said a short, specific prayer of thanks for the week and a short, specific request for steadiness in the morning, the kind that was the right length for what it was, and then I went to bed.
Thomas, following twenty minutes later, paused at the dormitory door. "Nicholas," he said.
"What?" I said.
"The shoulder drops before the cast," he said. "Pryce told me in October. I forgot to tell thee."
I lay in the dark and thought about this for a moment. "He told me Friday," I said.
The castle settled into the sounds it made in the late hours of a still night, stone and old timber and the distant movement of water in the channels below. Outside, March was doing what March did, which was to be slightly warmer than February had been and considerably colder than April was going to be. The ground beyond the outer wall was still frozen at depth. The northeast corner stakes were probably showing the amber glow in the dark.
I closed my eyes and slept.
