Assistant Master Corven was waiting in the potion hall.
The room smelled of smoke and crushed roots.
Most of the apprentices had already left for the evening, leaving only a few lamps burning above the worktables.
Corven stood beside the damaged flask from the previous day.
“You were present when this mixture became unstable,” he said.
“Yes.” “You warned the apprentice.” “Yes.” “He claims you distracted him.” “I did not.” “Did you speak to him?” “Yes.” “Before the flask cracked?” “Yes.” Corven stared at him.
Arin understood the problem.
The assistant did not necessarily believe the older apprentice, but he needed a report that could survive an argument with the student’s sponsor.
“Why did you speak?” Corven asked.
“The mixture was overheating.” “You were not assigned to that table.” “The reaction was visible.” “That is not an answer.” “It was going to fail.” Corven folded his arms.
“You believe noticing a problem gives you permission to interfere?” “No.” “Then why interfere?” “Because the result would have affected the entire laboratory.” The assistant’s expression remained stern.
After a moment, he picked up a thin ledger.
“Your work in Herb Hall has been consistent.
Mistress Halen says you reduce sorting errors.
You also repaired several damaged tools in the apprentice market.” Arin said nothing.
“You are observant.
You are careful.
You are also Grade One.” “Yes.” “Do you know what that means?” “That my spiritual force is weak.” “It means your usefulness must come from somewhere else.” Arin waited.
Corven opened the ledger.
“Potion laboratories lose resources in small amounts.
A little powder wasted here.
A cracked vial there.
A mislabeled herb.
A batch ruined because an apprentice cannot follow a measurement.” “That sounds expensive.” “It is.” “Why tell me?” “Because I want to see if you can reduce waste.” Corven removed a small glass jar from a shelf.
“Basic wound salve.
The academy makes hundreds of jars each month.
The recipe is simple.
The ingredients are not.” He handed Arin a sheet of paper.
The instructions were short.
Two portions of silverleaf paste.
One portion of ground redroot.
Half a portion of binding oil.
Heat until smooth.
Add cooling powder.
Stir seven times.
Seal.
Arin read the recipe.
“What is the problem?” “The salve separates after three days.” “How often?” “Nearly one batch in ten.” “Why?” “If I knew, I would not be asking you.” Arin looked at the ingredients.
The silverleaf paste was pale green.
The redroot powder was dark red.
The binding oil had a cloudy appearance.
He opened the ledger.
Each batch had a date, ingredient quantities, and the name of the apprentice who prepared it.
No storage temperature.
No grinding time.
No stirring speed.
No exact heat level.
The record was incomplete.
“Who wrote this recipe?” Arin asked.
“An old master.” “How long ago?” “Forty years.” “Has the ingredient supply changed?” Corven’s gaze sharpened.
“Yes.” “Which ingredients?” “Silverleaf comes from a different region now.
Redroot is cultivated instead of wild-gathered.” “Then the recipe may no longer behave the same way.” Corven tapped the ledger.
“Can you improve it?” “I can test it.” “That was not my question.” “It is the honest answer.” The assistant considered him.
Then he placed three sets of ingredients on the table.
“You have until tomorrow evening.” “May I use the ledger?” “You may.” “May I record additional variables?” “You may.” “May I ask the other apprentices how they prepare it?” “You may.” “May I request better measuring spoons?” “No.” Arin looked at the bent spoons on the table.
“Then the results will be unreliable.” Corven tossed him a straight metal spoon.
“Use that one.” Arin began with the first batch.
He followed the recipe exactly.
The silverleaf paste was thick and uneven.
The redroot powder contained several larger pieces.
The binding oil separated around the edges.
He heated the mixture until smooth, added cooling powder, and stirred seven times.
The salve looked acceptable.
He placed it in a jar and recorded the time.
Batch One: Silverleaf paste: two portions.
Redroot: one portion.
Binding oil: half portion.
Heat: unknown.
Stirring: seven rotations.
Result: visually stable.
The second batch used the same ingredients.
Arin changed only the grinding time.
He crushed the redroot powder until the larger pieces disappeared.
The mixture blended faster.
The third batch used the original powder but a lower heat.
It remained lumpy.
The fourth batch used ground redroot and lower heat.
The salve became smooth.
Arin stared at the two jars.
The recipe did not identify heat level or powder consistency.
It only gave broad instructions and assumed that each apprentice understood what “smooth” meant.
That was a poor interface.
A spell model could fail for the same reason.
The instructions might be correct while the execution remained inconsistent.
He continued testing.
By midnight, six jars stood on the table.
Arin’s eyes burned.
His fingers were stained red.
The room had grown cold as the rune-stoves dimmed.
He was sealing the seventh jar when Corven returned.
“You are still working.” “Yes.” “How many batches?” “Seven.” “How many failures?” “Two.” Corven picked up the first jar.
“What did you change?” “Only one variable per batch.” “Why?” “So I can identify which change caused the result.” The assistant looked at the ledger.
“You wrote more in one evening than the previous assistant recorded in a month.” “The previous assistant recorded only successful batches.” “Why is that a problem?” “Because failures contain information.” Corven gave him a long look.
“Everyone says that.
Few people behave as if they believe it.” He examined the jars.
“This one?” “Ground redroot.
Lower heat.
Five stirring rotations.” “And this?” “Same as the previous, but seven rotations.” “Difference?” “The five-rotation batch separated slightly around the edges after cooling.” Corven opened the jar and touched the surface with a glass rod.
He examined the residue.
“Correct.” Arin pointed to the recipe.
“The method should specify powder consistency and heat level.” “The heat level depends on the stove.” “Then the instruction should describe the visual sign of correct heat.” Corven looked toward the rune-stove.
“What sign?” “When the oil forms a thin ring around the paste, the temperature is too high.
When no ring forms, it is too low.
The correct mixture has a glossy surface without visible separation.” Corven was silent.
Arin realized he had overstepped again.
“Those are only observations,” he said.
“No.
They are useful observations.” Corven took a clean page from the ledger.
“Write the revised instructions.” Arin did.
Prepare the redroot until no large pieces remain.
Warm the binding oil until the surface becomes clear.
Add silverleaf paste gradually.
Maintain low heat until the mixture becomes glossy.
Add cooling powder.
Stir seven times at a steady pace.
Seal immediately.
Corven read the page.
“You have changed the recipe.” “I changed the instructions.” “That distinction matters to you?” “Yes.” “Why?” “A recipe describes materials.
Instructions describe process.
If the process is unclear, the same materials produce different results.” Corven’s eyes narrowed slightly.
“Does this apply to spell models?” Arin’s hand stopped.
He had not intended to mention spells.
“Possibly.” “Have you studied any?” “No.” “Then do not pretend.” “I am not pretending.” Corven set the page down.
“Tomorrow, prepare ten batches using your instructions.
If the failure rate remains low, I will show this to the laboratory master.” “Will I receive payment?” “No.” Arin waited.
Corven sighed.
“You will receive one copper for every ten successful batches.” “That is low.” “You are Grade One.” “That does not change the amount of work.” “It changes the number of people willing to replace you.” Arin accepted the answer because it was honest.
Before leaving, Corven placed a small pouch on the table.
Arin opened it.
Inside was a bottle of black ink.
He looked up.
“An advance,” Corven said.
“For the records.” Arin held the bottle carefully.
“Thank you.” “Do not waste it.” “I will not.” He returned to Dormitory Seven just before dawn.
Daren was awake, sitting against the wall with one hand pressed to his bruised ribs.
“How was the meeting?” he asked.
“I was assigned a problem.” “Did you solve it?” “Partially.” “Is that good?” “It means I have more work tomorrow.” Daren smiled.
“You sound happier.” Arin looked at the ink bottle.
“Perhaps.” He opened his notebook and added the new entry.
Potion salve: Old method inconsistent.
Main variables undocumented.
Single-variable testing identified likely causes.
Clear process instructions improve repeatability.
He paused.
Then he added: Payment received: one bottle of ink.
Not wealth.
Not power.
But a resource earned through thought instead of begging.
Arin capped the ink and placed it inside his locked chest.
For the first time since arriving at the academy, he felt something shift.
He was still Grade One.
Still weak.
Still surrounded by people who could hurt him.
But he had begun to create value that existed outside his spiritual force.
And in a place where everything had a price, that could become its own kind of strength.
