River herb was easy to identify.
Long leaves, serrated edges, green with a yellow line down the center that made it unmistakable even for someone who'd never foraged in their life. Kael knew this because he'd spent ten minutes memorizing the description on the mission slip before leaving, which was exactly the kind of over-preparation he did when he knew he couldn't afford to make mistakes.
The Lesser Forest was exactly what its name promised. Medium trees, marked paths, enough sunlight filtering through the branches that navigation was straightforward. The kind of forest where new adventurers did their first missions without anyone worrying too much about them.
The area marked on the map was south, next to a stream that cut diagonally through the forest. Kael followed the main path, turned at the second junction like the map said, and within twenty minutes he was crouched by the stream cutting river herb with his work knife and depositing it in his pack with the care of someone who knew his pay depended on them staying fresh.
Lyra was sitting on a rock by the water.
Doing nothing. Just existing, which was what slimes did by default. But Kael had started noticing that the way Lyra did nothing was qualitatively different from the way other slimes he'd seen in his life did nothing. Normal slimes just were. Lyra observed.
Right now, it was observing the stream.
"What are you looking at?" Kael said, not expecting an answer.
Lyra didn't respond. Naturally. It was a slime.
Kael cut more herb. The stream sounded nice. The birds sounded nice. Everything sounded like a quiet morning in a safe forest, and Kael thought that maybe this adventuring thing wasn't as hard as people made it out to be if you just picked the right missions with a level head.
That thought lasted approximately four minutes.
---
The problem was the map.
Specifically, the problem was that the map was old and the stream had shifted course slightly since someone drew it, which meant the circled area no longer exactly matched where Kael was, which meant Kael had been cutting herb in the right place but had followed the stream about fifty meters further north than he should have while looking for where the herb grew densest.
Fifty meters north of the circled area put Kael at the edge of the Lesser Forest's northeast sector.
The northeast sector where mission C-17 reported shadow wolf activity.
Kael didn't know any of this because he hadn't read mission C-17.
Lyra did know.
Lyra had been staring ahead for fifty meters with the specific attention of something that had detected a problem and was evaluating options.
"Almost got enough," Kael said, crouched over a particularly good patch of river herb. "Maybe ten more minutes and—"
The first shadow wolf came out of the trees on the left.
Kael saw it and his brain processed the information in the following order: large animal, dark fur almost black, yellow eyes, about the size of a very big dog but with the wrong proportions, muscle too dense for a normal dog, rank—
Rank C.
"Ah," Kael said.
The second wolf came out on the right.
The third appeared directly ahead, blocking the path back.
Kael stood up slowly. The pack with the herbs hung from his left shoulder. The sword was on his right hip. Lyra was on his left shoulder, completely still, with a stillness that was different from its normal stillness — more concentrated, like water before it boiled.
The three wolves didn't attack immediately. Shadow wolves weren't impulsive beasts. They were coordinated. They assessed. They waited for the moment when the target made the mistake of moving in the wrong direction.
Kael knew this because he'd read about shadow wolves in one of the village books describing beasts he never expected to encounter.
That knowledge wasn't especially helpful right now.
"Okay," he said, quietly, mostly to himself. "Okay. Three of them. Rank C. I'm rank F. The math here is pretty clear."
He drew his sword anyway. Not because he thought it would do much, but because it was what people did in these situations and familiar movements helped prevent full panic.
The wolf on the left tensed. Getting ready to jump.
Kael calculated he had about two seconds before the situation resolved itself in a highly inconvenient way for him.
Then something shifted in the weight on his left shoulder.
It wasn't dramatic. It wasn't an explosion of light or a powerful sound. It was simply that Lyra, which had been still like water before it boiled, stopped being still.
The wolf jumped.
Lyra got in the way.
What the wolf hit wasn't Kael's shoulder but something that had extended from that shoulder at the last moment — a red surface, dense, that absorbed the impact with a dull sound and didn't move. The wolf bounced backward with the confused expression of a creature that had just attacked something that should have given way and didn't.
Kael looked at his left shoulder.
Lyra was there. Normal size. Completely normal.
He looked at the wolf shaking its head on the ground.
"My armor?" he said, looking at the leather jacket he was wearing.
The leather jacket was standard. It had no properties that absorbed C-rank impacts.
He didn't have time to resolve that contradiction because the second wolf attacked from the right — straight at his side, faster than the first, with the calculated angle of something that had hunted before.
Lyra absorbed that one too.
This time Kael saw it. Not completely — it was fast and from a difficult angle — but he saw that something red extended and contracted in the space between the wolf's fang and his side. Something that wasn't his clothes or his gear or anything he'd brought.
The second wolf also bounced.
The third, the one blocking the path, didn't attack. It stayed where it was, reevaluating, its yellow eyes moving from Kael to the point on his shoulder where Lyra lived and back.
The three wolves exchanged something that in less intelligent animals would have been just instinct but in shadow wolves was closer to communication. The one on the ground got up. All three backed up a step.
Kael didn't move.
The wolves backed up another step.
Then they turned and vanished into the trees with the silent speed that made that species particularly unpleasant to encounter in the forest.
The forest fell silent.
Kael lowered his sword.
Looked at Lyra.
Lyra looked back at him.
It was exactly the same size as always. Red. Calm. With the same expression it had when observing the stream or the mission board or anything else it considered worthy of attention.
"Was that you?" Kael said.
Lyra didn't respond. Naturally.
Kael thought about what he'd seen. The first wolf bouncing. The second. The way all three had backed away looking specifically at the slime on his shoulder. The red surface that had appeared and disappeared too fast to properly analyze.
He looked for an explanation.
Found them in the following order: one, the wolves were weaker than normal from some disease or condition; two, my jacket has some property I didn't know about; three—
He looked at Lyra.
Lyra glowed softly. Once.
Three, Kael thought, rare mutation.
He nodded to himself. Sheathed his sword. Checked his pack — the herbs were fine, none crushed during the incident. Checked the map. Identified precisely where he'd made the directional mistake.
Turned south.
"We're leaving," he said.
He started walking. Lyra settled on his shoulder with the specific adjustment of something getting used to a familiar movement.
They'd been walking back for two minutes when Kael processed something else.
The wolves had backed away looking at Lyra.
Not at him. Not at the sword. At Lyra.
Three C-rank shadow wolves had assessed an F-rank slime and decided it wasn't worth it.
Kael filed that information somewhere in his head alongside "check maps more carefully before leaving" and "confirm zone boundaries before gathering" and kept walking.

The guild receptionist counted the herbs, verified they were fresh, weighed them on the counter scale, and wrote in her book.
"Mission F-03 completed," she said. "Two copper coins."
She slid them across the counter.
Kael took them. Added them to the four he already had. Six copper coins total, which was enough for a decent dinner and nothing else.
"Anything else available today?" he asked.
The receptionist checked the board.
"One F-rank mission left. Package delivery to the smith on South Street. One copper coin, no deadline."
"I'll take it."
He signed. Picked up the package from the side counter. Turned to leave.
That's when he heard the voice from across the guild hall.
"Who the hell eliminated my targets?"
It was a man around twenty-five with plate armor that clearly hadn't been bought used. Dark hair, tense jaw, his adventurer's plate hanging from his belt with the C-rank color visible from any reasonable distance. He was holding a mission slip and had the expression of someone who'd come to collect on something that no longer existed.
He was talking to the guild assistant by the board. The assistant was checking the register with the face of someone who didn't want to be in this conversation.
"According to the field report, activity ceased this morning in the northeast sector," the assistant said. "But there's no record of any adventurer completing mission C-17. Technically the targets could have migrated on their own—"
"Shadow wolves don't migrate," the man said, with the patience of someone explaining something obvious. "Someone scared them off. Or eliminated them. And that someone stole forty silver coins of reward from me."
The assistant looked at the register. Then at the board. Then, for reasons probably related to it being his job to notice these things, looked toward the main counter.
Looked at Kael.
Kael had a package under his arm and a red slime on his shoulder and the expression of someone who'd just realized he should have left thirty seconds earlier.
The C-rank man followed the assistant's gaze.
His eyes landed on Kael.
Dropped to the F-plate on his belt.
Rose to the slime on his shoulder.
"You," he said.
"I deliver packages," Kael said, holding up the package. "I'm a courier. Heading to the smith."
"You were in the northeast sector this morning."
"I was in the south sector. Collection mission. It's in the register."
"The south and northeast sectors share a border in the Lesser Forest."
"The borders are marked on the map."
"Did you read the map correctly?"
Kael didn't answer that.
The silence was answer enough.
The C-rank man crossed the guild hall in eight strides and planted himself in front of Kael with the height and mass of someone used to that resolving most of his conversations.
"Daven Cros, rank C," he said. "That mission was mine. Forty silver coins. I want them."
"I don't have forty silver coins," Kael said.
"Then we have a problem."
Lyra, on Kael's shoulder, lowered the temperature of its mass by exactly one degree.
Kael felt the cold on his neck without understanding where it came from.
"Look," Kael said, with the tone of someone looking for reasonable exits. "I didn't eliminate any wolves. I scared them off by accident while crossing the wrong zone. It's not the same. I didn't complete your mission, I just ruined the conditions. Those are legally different things."
Daven stared at him.
"Legally?"
"Guild regulations distinguish between active interference and incidental interference. Article 12, if I remember correctly."
He'd read the full regulations the night before. Just in case.
Daven stared at him for three full seconds. Then looked at the assistant.
The assistant found the regulations with the face of someone who'd rather be anywhere else.
Found Article 12.
Read it.
"Technically," he said, very carefully, "incidental interference doesn't generate direct compensation obligations. It generates a review claim which—"
"Fine," Daven said, without taking his eyes off Kael. "Then a compensation duel. Article 15."
Kael knew Article 15. He'd read that too.
The compensation duel was the solution when the legal route took too long and both parties preferred to settle things directly. The duel's outcome determined who was right. It was perfectly legal within the guild as long as it happened in the back courtyard with no lethal weapons active.
It was also, in any reasonable scenario, a very efficient way for Daven Cros to recover his good mood at the expense of Kael's bones.
The guild fell silent. Three adventurers eating at the back tables stopped eating. The receptionist closed her book with the gesture of someone who knew she wouldn't need it for a while.
Kael looked at the exit.
Looked at Daven.
Looked at his own four copper coins and two newly earned ones that weren't going to solve anything.
"Back courtyard," Kael said.
---
The Varren guild's back courtyard was a rectangle of packed dirt surrounded by a wooden fence that had received enough magical impact over the years to develop an interesting texture. There was a line painted in the center. The rules were simple: first one to cross the line on the opponent's side wins, or first one who can't get up.
The three adventurers from the back tables had followed. The assistant too. The receptionist watched from the back window of the building with her arms crossed and the expression of someone who already knew how this was going to end.
Kael stood on his side of the line.
Daven stood on the other with the relaxed posture of someone who'd done this many times.
Lyra was still on Kael's shoulder. No one had told it to get down, and Kael hadn't thought to ask.
"No lethal weapons," the assistant said from the edge. "Free mana. Start when I say."
Daven flexed his fingers. Mana condensed around his right hand with the ease of someone who'd done it ten thousand times — dark blue, dense, the kind of mana a C-rank adventurer accumulated after years of work.
Kael held his sword with the grip pointed down. He wasn't going to attack first. First he needed to see what Daven would do.
"Go," the assistant said.
Daven's spell came straight at him. No flourishes. Concentrated mana impact, enough to knock down a D-rank without trouble.
It hit Kael square in the chest.
Kael didn't move.
The guild went silent.
Daven looked at his own hand. The technique had been correct. The channeling had been correct. The impact had been real — he could feel the feedback in his knuckles, which meant he'd hit something.
"You okay?" one of the adventurers from the back said, clearly confused about who to direct the question to.
Kael checked his chest. No visible damage. No pain. Like the spell had hit a wall instead of a person.
He looked at Lyra.
Lyra looked back at him.
Kael remembered the shadow wolves. The first bounce. The second.
Rare mutation, he thought, and took a step forward.
Daven threw the second spell, stronger. Twice the mana. The kind of hit that left a mark on the wooden fence when it missed.
Kael didn't move either.
Something in Daven's face changed. Not fear exactly — C-rank adventurers didn't feel fear facing someone F-rank — but the specific discomfort of someone whose understanding of how the world worked had just been challenged.
He charged the third spell. Kael saw his knuckles go white. Saw the mana condense denser than the previous two times, blue almost black, the kind of hit you saved for when the first two weren't enough.
Kael didn't step back.
He stepped forward.
The spell released.
And Lyra, which had been silently absorbing, absorbing and storing and swelling in a proportion no one in the courtyard had noticed because the changes had been millimeter by millimeter, released exactly the amount of energy it needed.
It wasn't an attack. It was just Daven's spell returned with the exact weight of three C-rank spells plus the spell's own launch inertia.
Daven went flying.
It wasn't violent. It was simply physical — the inevitable result of the amount of force involved — and Daven traveled backward about two meters before crossing his own line and landing on the wrong side of the dirt with a sound that made everyone in the courtyard close their eyes in solidarity.
Silence.
Daven was alive. Conscious. Staring at the courtyard sky with the expression of someone actively reorganizing their mental model of how F-rank slimes worked.
The assistant looked at the line. Looked at Daven. Looked at Kael.
"Kael Dross, rank F," he said, with the voice of someone also reorganizing a few things. "Wins the compensation duel."
Kael looked at Lyra.
Lyra was exactly its usual size. Red. Calm. Like it had spent the last ten minutes watching the stream instead of absorbing three C-rank spells.
"Mutation," Kael said quietly.
"What?" the assistant said.
"Nothing," Kael said. "Do I still need to deliver that package to the smith?"
---
From the second-floor window of the guild, a woman no one had noticed watched the end of the duel with her arms crossed and a cup of coffee going cold in her hand.
She'd been an adventurer for twenty years. She'd seen beasts of all ranks. She'd studied the bonds between adventurers and companion creatures long enough to know when something didn't fit into any known category.
What she'd just seen didn't fit into any known category.
She looked at the red slime on the kid's shoulder as he picked up his package and got ready to leave.
She sipped her cold coffee.
Walked down the stairs very slowly.
