Chapter 68: Alchemy Class
The alchemy laboratory was on the second floor of the north wing, which the campus map labeled simply as Practical Sciences and which smelled, from the corridor outside, of heated copper and something green and medicinal that had soaked into the walls over a long period of time.
Inside, the workbenches ran in two rows down the center of the room, each fitted with a stone heating element, a set of graduated measuring vessels, and a bracket above that held the mana conduction rods in their correct positions.
The cabinets along the east wall were organized by reagent category. The cabinets along the west wall were organized by something else, a system not immediately legible.
We filed in.
Professor Elara set her bag on the front bench with the efficiency of someone who had arrived at the optimal placement through repetition. Older than Hiratsuka. Her attention had the quality of someone who had stopped waiting for students to catch up and had arranged her expectations accordingly.
She looked at the class.
"Healing potion. First task. You will watch me complete it once. Then you will complete it. The pair who produces a functional result first receives the first-rank materials voucher for the semester."
She pulled on her work gloves and picked up a sprig of silverleaf.
"What happens if you powder this?"
The room went quiet. Someone near the back: "It extracts faster?"
"No." She set it down and picked up the grinding stone. "The cellular matrix breaks down. You lose the fibrous structure that holds the essence during extraction. You will produce something that smells correct and does nothing."
She reached past the vessel to straighten a reagent bottle that had been sitting two degrees off-center, mid-sentence, without looking at it. "Remember that."
She worked the paste with slow, consistent pressure.
"The leaf structure retains its anti-inflammatory properties until the cellular matrix breaks down. You are not looking for powder. You are looking for paste with residual fibrous structure. The fiber holds the essence during the extraction phase."
Thirty seconds. Then she transferred the paste to the preparation surface and went to the heating element.
"Pure water. Mana-clean. The bench water qualifies." She poured a measured amount into the primary vessel and brought it to a low heat. "You are not boiling. You are preparing the medium."
She added the bloodmoss to a secondary vessel and began a slower preparation.
"Bloodmoss releases its essence under gentle compression. Not grinding. Not heat. Compression, sustained, at a consistent pressure." She worked it with two fingers and straightened the label on a second bottle as she reached past it.
"You can feel when the release is complete. The texture changes. Stop before it starts absorbing back."
The essence went into the primary vessel.
"The mana infusion is where most of you will fail the first time. You will infuse at your own frequency because that is what you are accustomed to. Healing compound does not work on your frequency. It works on the bloodmoss’s natural resonance, approximately half a register lower than standard affinity output."
A student in the second row shifted. "How do you find the register if you haven’t felt it before?"
"You won’t find it today. You will find a rough approximation of it today. Exact calibration comes from repetition." She held her hand above the vessel.
The mana came down differently than any standard technique, slower, lower in frequency, the compound responding visibly, the color shifting from pale green to the deeper tone that indicated binding. "If your output is too high the compound clouds. If it is too low nothing happens. The color tells you. Watch the color."
"Thirty seconds at resonance. Count it. Then the stabilizing crystal. Break the edge, not the core. The interior is inert. The outer edge carries the mana lattice."
She broke the crystal against the bench edge in one motion and added the fragment.
The compound settled. The color held.
She tested it with a drop on the back of her wrist.
"Functional. You have forty minutes. The ingredients bench is in the back. The pairing list is on the board."
She peeled off her gloves and went to her desk.
The pairing list had been written before we arrived.
Iris read it and went to the ingredients bench.
Tessira was already there, which produced a half-second of mutual assessment before Tessira stepped slightly to the left and began organizing the ingredients.
"Silverleaf first," Tessira said.
"I know," Iris said.
"The grinding stone on the left has a wider surface area."
Iris looked at the grinding stones.
"That one," she agreed.
They went to the bench.
Violet reached the ingredients at the same time I did. She took the silverleaf without discussion, which meant she had already divided the task during the demonstration. I took the bloodmoss and the measuring vessel and followed her to the bench.
"The resonance," she said, setting the leaf down. "Half a register lower."
"Yes."
"You already knew that."
I started the paste preparation.
The silverleaf resisted for the first few turns of the grinding stone. Too much force and the fibers would collapse against the surface. Too little and nothing would form.
I found the right pressure somewhere in the second rotation and the leaf began to break down the way Elara had demonstrated, slowly, the texture staying intact rather than compressing to powder.
"The game had a mechanic," I said. "The mana frequency requirement was one of the parameters we calibrated during development. In practice it sits at approximately forty-five percent of standard output frequency."
Violet looked at me.
"You worked on the game adaptation," she said.
"Yes."
She returned to her preparation.
"That is either very useful or a form of cheating," she said.
"It is useful. Whether it is cheating depends on whether you think theoretical knowledge from a different context counts as an advantage."
"The professor said pay attention during the demonstration. She did not specify to what."
She went back to the leaf.
Iris never once looked at the demonstration notes on the board.
Her paste was smoother than mine by the time I crossed to check the secondary materials. She had the bloodmoss essence ready before Tessira finished the silverleaf preparation, working the compression at exactly the pressure Elara had used, two fingers, sustained.
She adjusted the mana output before the color shifted.
Tessira noticed from two inches away and said nothing about it.
"You have done this before," Iris said.
"Spirit bonds require maintenance compounds," Tessira said. "Basic preparation is part of the contractor curriculum."
Iris measured the water into the primary vessel.
"Tell me about the resonance," she said.
"You do not know the frequency," Tessira said.
"I know the frequency. I do not know what it feels like from the inside."
Tessira thought about how to answer that.
"It is like reducing output deliberately," she said. "The way you would modulate mana to avoid triggering a sensitive instrument. Not suppression. Reduction with precision."
Iris activated the heating element and stood with her hands above the vessel.
"Like that," Tessira said, after a moment.
"Yes," Iris said.
From the fifth bench, thin greenish smoke. The specific color of a heating element pushed past the correct temperature. Professor Elara walked that direction without being called. She did not look at the student. She looked at the vessel, asked one question, and moved away. The student started clearing the bench.
From near the window, the sound of glass against stone, then a particular silence.
"Twenty-five minutes remaining."
Elara’s voice from the front desk. She had not looked up.
Someone on the third bench said something under their breath. The sound of a vessel moved too fast and then caught before it fell.
Violet kept her hands level above our vessel.
"You are slightly high," I said.
She adjusted without responding.
"There," I said.
The color began shifting. She held the output and counted under her breath.
"Twenty-eight. Twenty-nine. Thirty."
She withdrew.
I broke the stabilizing crystal edge against the bench surface, broke it again to get the fragment size right, and added it.
The compound settled. Held.
Violet carried it to the professor’s desk.
"Professor Elara."
The professor came over. She checked the vessel, then the bench, then the preparation evidence: the paste residue, the used compression cloth, the crystal fragments.
She tested it the same way she had tested her own.
"Functional," she said.
She looked at Violet, then at me.
"How. The resonance adjustment was precise."
"I had theoretical preparation," I said. "The mana frequency requirement for bloodmoss binding appears in pre-classification alchemical texts. Compiled from materials predating the current institutional framework."
She held the answer for a moment.
"Those records have not been in public circulation for two centuries," she said.
"I am aware," I said.
She set the vessel on the bench and picked up a small red voucher from her document stack.
"First-rank materials access. Joint award. The second-rank process requires techniques covered in month three. I suggest you use the voucher for reagents you will need by then."
She set the voucher on the bench between us.
At the next station, someone stopped mid-motion. A girl three benches down turned to look. A quiet voice from somewhere behind us: "Already?"
Her partner: "First-rank."
Neither said anything else. They turned back to their work faster than they had been moving before.
She walked back past the benches, pausing at Iris and Tessira’s station without being called. She did not speak to them. She straightened the bloodmoss vessel one centimeter to the left. She wrote something on her document.
She moved on.
Violet held the voucher.
"The Keeper’s records," she said.
"Yes."
"You have access to them."
"Yes."
She set the voucher on the bench between us and did not ask the next question. Not because she had accepted the answer. She had decided this was not the moment for it. Filing it for later, the same way I filed things.
Three benches over, Iris and Tessira placed their stabilizing crystal.
"Hers is better quality," I said.
Violet studied it.
"The paste to essence ratio. More precise extraction." A pause. "She will have the first-rank quality result even if she finished second."
"She made it before she sat down," I said.
Iris looked across the room at the voucher on our bench. Then she said something to Tessira.
Tessira adjusted the mana output slightly.
She looked across at me.
I raised one hand.
She turned back to the bench.
At her desk, Professor Elara opened her records notebook to the session page.
Beneath my name, she wrote: Prior knowledge. Pre-classification source. Confirm.
Beneath Iris’s: Perfect resonance. No adjustment required. Watch.
She straightened the edge of the notebook against the desk surface and left it open.
