District 14's E-rank barrier smelled like wet fur and ozone.
Voss ducked inside at oh-six-twelve, two minutes behind the all-clear signal. The clearance squad was already packing up outside — six Attuned, D-rank average, led by a stocky woman with a halberd still wet with monster blood. They didn't look at Voss as he passed. Carvers were furniture.
Inside the dome, three shadow lurkers lay in a scattered triangle. Dead approximately four minutes, based on the residual heat when he pressed his fingers to the first body. Good. Well within the window.
He activated Thread Sight.
The threads bloomed. Gold with that greenish speed undertone, rising from the lurkers in luminous curtains. More vivid than anything he'd seen so far — the freshness made them brighter, more defined, each filament individually visible rather than blurring into the mass.
And there. In the largest lurker, coiled through its central nervous system like a vine through a trellis. An ability thread.
It was thick as his thumb. Dark green, almost black at the center, pulsing in a rhythm that matched no heartbeat because the heart had stopped. The stat threads drifted loose, passive, waiting to be picked. The ability thread gripped the body. Rooted itself. Alive in a way the stat threads weren't.
Voss harvested the stat threads first. Speed threads, five of them, pulled clean from the muscular system. Each one delivered its jolt of quickness — his body adjusting, recalibrating, the world slowing down a fraction of a beat. He moved to the second lurker. Five more speed threads. He was pushing his daily limit now, the fatigue building behind his eyes, but the ability thread in the third lurker was calling to him.
Not literally. It didn't speak. But the way it pulsed, the way it held its shape when every other thread was already beginning to fade — it was different. It mattered.
He knelt beside the third lurker. Extended his hand. The stat threads parted around his fingers like curtains. The ability thread didn't move. It waited.
Voss grabbed it.
Pain.
Not the mild warmth of stat thread absorption. A fist of hot wire driven through his palm and up his arm, burning through nerve channels he didn't know he had. The thread fought him — not with intelligence but with inertia, the raw stubborn weight of something that didn't want to be moved. He pulled. It resisted. His vision whited at the edges and his jaw locked shut around a scream that never reached his throat.
The thread tore free.
It slammed into him like a car. Not into his muscles or his bones — into something deeper, some architecture of self that the stat threads had never touched. His vision strobed. He saw the inside of the barrier in negative, black dome and white ground, and then reality reassembled itself with a new channel carved through his nervous system, a pathway that hadn't existed three seconds ago.
Voss collapsed beside the dead lurker. His right hand was shaking — the first time his hands had shaken since he was twelve years old, on his first day at the Carver's Guild, holding a blade over his first monster corpse.
He lay there for two minutes. Breathing. Letting the pain recede from a scream to a roar to a dull ache that settled behind his sternum.
Then he stood up and stepped through a shadow.

Shadow Step.
That's what the lurker's ability thread gave him. Not a name — the ability didn't come with a label. But when Voss focused on the new channel in his nervous system and pushed mana through it, his body dissolved into the nearest shadow and reconstituted ten meters away in the next one.
He tested it in an empty warehouse district three blocks from the Guild. Midnight. No cameras, no foot traffic, no one to see an F-rank Carver teleporting through pools of darkness between loading docks.
The mechanics were straightforward. Find a shadow. Push. Arrive in the nearest shadow within a ten-meter radius. Elapsed time: approximately half a second, experienced from the inside as a moment of cold compression — his body flattened, stretched, squeezed through a space that shouldn't fit a human, then expanded back to normal. Disorienting the first three times. Manageable by the fifth.
Cooldown: thirty seconds. He timed it with his watch. Exactly thirty seconds between each use, regardless of distance or shadow quality. Below that threshold, the channel simply refused to fire.
Range: ten meters, hard cap. He tried pushing for eleven and the ability cut out mid-transit, dumping him out of the shadow wall three feet from his starting position. Unpleasant. Like being spat out.
Shadow requirement: the entry and exit points needed actual shadows. Not darkness — shadows. Cast by objects, with defined edges. A pitch-black room didn't work. A lamp casting a shadow against a wall did. The ability read the shadow as a doorway, not the darkness as a medium.
Voss ran twenty-three tests. Documented everything. Time, distance, shadow quality, physical sensation, mana cost. The mana drain was light — each use took maybe three percent of his total capacity. He could Shadow Step over thirty times before running dry. More, if he waited for passive regeneration between uses.
By the time he finished, his legs were steady, his breathing was even, and he understood what he was holding.
A combat ability. Real, functional, equivalent to what a C-rank Shadow-class Attuned might develop after years of training. Acquired in one agonizing moment from a dead E-rank lurker.
He sat on a loading dock and looked at the city skyline. Distant barriers dotted the horizon — translucent domes catching the light pollution, markers of Rifts that had opened and been contained. Each one held dead monsters. Each dead monster held threads.
For the first time in twelve years, the math was changing.

He told Mira the next evening.
She made him demonstrate. Her hospital room had a lamp on the side table that cast a clean shadow against the far wall. Voss stepped into it and came out on the other side of the room. Mira's eyes tracked his disappearance and reappearance with the focused intensity of someone who'd just had a hypothesis confirmed.
"Do it again," she said.
He did. Three times, from different angles, while she timed him on her laptop's stopwatch and measured the distances with a measuring tape she'd borrowed from the physical therapy ward.
"Thirty-second cooldown. Consistent." She typed with her thumbs — the paralysis had taken most of her finger mobility overnight, another step down the staircase. "Ten-meter range. Shadow-dependent entry and exit. Mana cost negligible relative to your enhanced pool."
"The absorption was different from stat threads," Voss said. "Painful. Took a full day to recover. I couldn't absorb anything else for twenty-four hours afterward."
"That's consistent with a higher integration burden. Stat threads are passive modifiers — they enhance what's already there. An ability thread is installing new architecture. Your body needs time to build the channel." She looked up from her screen. "You said the lurker was E-rank?"
"E-rank shadow lurker, standard classification."
"And the ability it gave you is functionally C-rank equivalent."
"Based on my reading, yes. C-rank Shadow Attuned develop short-range teleportation as a mid-tier ability. Mine has the same range and similar mechanics."
Mira pulled up a document on her laptop — the RDC's public ability classification index. She scrolled through shadow-type abilities, cross-referencing. Her lips moved silently as she read.
"The public index lists shadow teleportation as a Class 3 mobility skill," she said. "Requires C-rank minimum mana capacity and specialized shadow affinity. You have neither."
"I have the skill."
"Which means the ability thread bypasses normal awakening requirements. It doesn't give you shadow affinity — it gives you the end product. The completed channel with the completed ability, extracted from a creature that developed it through its own biology."
"Like an organ transplant."
"Exactly like an organ transplant." She closed the laptop. "Which means the quality of the ability depends on the quality of the source. An E-rank lurker gave you a C-rank equivalent skill. What would a C-rank lurker give you?"
"Don't know. Haven't found one fresh enough."
"What would a B-rank give you? An A-rank?"
"Mira."
"A boss monster? An S-rank Rift Lord with abilities that SSS-rank Attuned would kill for?"
"Mira."
She stopped. Took a breath. Her hands were shaking worse than usual — not from the paralysis this time but from something else. He recognized it because he'd felt it himself, standing in that warehouse at midnight, stepping through shadows. The tremor of someone standing on the edge of something vast and looking down.
"Okay," she said. Steadier. "Okay. Let's be systematic about this."
She opened a new spreadsheet. Headers across the top: Thread Type, Source Rank, Source Species, Ability Gained, Equivalent Rank, Absorption Pain (1-10), Recovery Time, Side Effects.
"We need a classification system," she said. "And we need data. A lot more data."
"I've got six shifts this week. Four E-rank cleanups, one D-rank, and one C-rank if I can get the assignment."
"C-rank barriers require a squad escort for Carvers. Guild protocol."
"I know. I'll figure it out."
She gave him a look. The one that meant she was cataloging his risk tolerance and finding it unsatisfactory. "You need to be strategic about which threads you absorb. If the daily limit is five stat threads and one ability thread per forty-eight hours, you can't afford to waste absorptions on low-value targets."
"I wasn't planning to."
"Good. Priority one: mana threads. Every mana sprite or mana-type monster you can access. Your Thread Sight is your primary tool — improving it improves everything else."
"Agreed."
"Priority two: defense threads. You're going into increasingly dangerous situations. If something goes wrong, your body needs to survive the first hit."
"Agreed."
"Priority three: ability threads from the highest-rank sources you can access. One every forty-eight hours. Be selective. The ability needs to complement your combat style, not just be powerful in isolation."
"I don't have a combat style."
"You have carving blades, anatomical knowledge, and Shadow Step. That's a style. Hit-and-fade. Precision targeting of structural weaknesses while staying mobile." She pulled up a new tab — monster anatomy diagrams she'd bookmarked from the RDC database. "Here. Study these. If you know where every monster species' critical structures are, you can end fights in single cuts."
"I already know most of them."
"You know them for carving. I want you to know them for killing." She highlighted a diagram of a stone beetle's underside. "The ventral nerve cluster. One blade, forty-five-degree angle, through the gap between the fourth and fifth carapace plates. Instant paralysis."
Voss leaned forward. The diagram was familiar — he'd carved hundreds of beetles. But he'd never looked at it this way. Not as a map for disassembly but as a targeting guide.
"Structural integrity points," he said.
"Every monster has them. The joints. The nerve clusters. The mana pathways. You've been studying them for twelve years. You just never had a reason to use that knowledge offensively." She closed the laptop and met his eyes. "Now you do."
He took the list she'd prepared — twelve common monster species, critical strike points for each, ranked by lethality and accessibility. She'd compiled it from RDC field manuals, research papers, and three textbooks that were technically restricted to A-rank combat personnel.
"How did you get access to restricted manuals?" he asked.
"I proofread a Colonel's research grant. He owed me a favor." She paused. "Three favors."
Voss folded the list and put it in his jacket. At the door, he stopped.
"The clusters," he said. "District 14. Have they changed?"
Mira wheeled herself to the corkboard. Three new pins had been added since his last visit. "Two more E-rank barriers in the past forty-eight hours. The concentration is increasing."
"That's not normal."
"No. It's not." She traced the pattern with a finger that barely responded to her commands. The string between the pins formed a shape — not random, not scattered. Converging. Moving toward something. "I don't have enough data to say what it means. But barriers don't cluster without a reason. Either there's a deep Rift source generating them, or something is pulling them."
"Pulling them."
"Directing them. The same way you described those wolves in District 22 — fighting in formations they shouldn't know. Something coordinating at a level the RDC isn't looking at because they classify each barrier as an independent event."
The room was quiet. The mana monitor beeped. The frost in Mira's hands crept another fraction of a percent inward, invisible, relentless.
"I'll get you more data," Voss said.
"From the barriers?"
"From the dead."
He left. The hallway was long and white and smelled like chemicals. His shadow stretched ahead of him under the fluorescent lights, and he had to stop himself from stepping through it.
He had a weapon now. A real one. Not just the threads but the knowledge of where to cut, refined by a sister who'd turned a hospital room into an intelligence center and a corkboard into a war map.
Mira couldn't walk. Couldn't hold a blade. Couldn't enter a barrier or face a monster or pull a thread from a corpse.
But she could aim him. And that, Voss was starting to understand, might matter more than any thread he'd ever absorb.
