Marcus's left hand wouldn't close.
He'd been testing it for six minutesâNoah had counted, the way he counted everything now, the developer's brain converting human behavior into data points because data was easier to hold than concern. Open. Close attempt. Fingers curling to approximately seventy percent of full range. The swelling around the second and third knuckles had turned the color of overripe plums, and the skin across his palm was split in two places where he'd gripped the Mirror Sovereign's adaptive shell bare-handed.
His right hand was worse. He'd stopped testing it.
"Functional," Marcus said to no one in particular. The word was a status report, not an assessment. Marcus communicated in system updatesâoperational, compromised, offline. His vocabulary for self-evaluation contained no room for gradation between *works* and *doesn't work*. The fact that he couldn't grip his shield without his face going blank in a way that meant he was routing pain through every detour his nervous system offered was, by Marcus's internal classification, still functional.
Noah watched him from across the arena and ran the calculation he didn't want to run. A Guardian who couldn't close his hands around a shield handle was a Guardian in name only. Marcus's class identity was built on the physical interface between palm and grip. Without that interface, he was two hundred and twenty pounds of military training and nothing to channel it through.
Time to recovery: unknown. The Tower didn't provide healthcare timelines. It provided damage and left the repair logistics to the damaged.
**[FLOOR 80 â POST-GUARDIAN ZONE UNLOCKED]**
**[SAFE PASSAGE TO FLOOR 81 STAGING AREA AVAILABLE]**
**[REST PERIOD: UNLIMITED WITHIN THIS ZONE]**
The notification materialized as they gathered themselves from the arena floor. Unlimited rest. The word sat wrong in Noah's processing queue. The Tower didn't give unlimited anything. Every resource came with a cost structure, every benefit with a corresponding drain. Unlimited rest meant the Tower wanted them resting. Wanted them here. Which meant being here served the Tower's objectives in a way that not being here wouldn't.
But the alternative was pushing forward with a party that was running atâhe scanned each of them, quick diagnostic passesâmaybe fifty-five percent aggregate combat effectiveness. Marcus's hands. David's depleted reserves and the cardiac stress that wouldn't show on any status screen. Kira's thigh, which Maya had re-bandaged twice in the last hour, the gauze saturating faster than field medicine could justify. Maya herself, still moving like someone whose inner gyroscope had been knocked out of calibration, reaching for walls that were closer or farther than her spatial processing expected. Emma's blade with its hairline fracture, a weapon that might hold or might shatter on the next hard contact, a coin flip disguised as equipment.
Fifty-five percent was generous. He was rounding up because rounding down made the forward projection unsurvivable.
"We rest," he said. "Full recovery. No rushing."
Nobody argued. That was its own data point. This party argued about everythingâformation positioning, resource allocation, whose turn it was to take point on unknown floors. A party that didn't argue with the call to rest was a party that needed the rest badly enough to bypass their standard operating friction.
---
The post-guardian zone was through a passage that opened in the arena's far wall after the Mirror Sovereign's remains finished dissolving. The passage was twenty meters of dim corridor that opened into something Noah's developer brain filed under *unexpected architecture*: a cavern the size of a warehouse, naturally lit by bioluminescent formations on the ceiling that cast the space in shifting blue-white light. The floor was smooth stone, worn by what looked like centuries of foot traffic. Along the walls, alcoves had been carvedâor grown, the organic geometry suggested growth rather than constructionâinto sleeping quarters, each one fitted with a stone platform covered by material that wasn't quite fabric and wasn't quite moss but was softer than either.
Water ran along channels in the floor, collected in a basin at the cavern's center. Clean. Cold. Noah tested it with a finger and his body responded before his brain could analyze the sampleâhis throat constricted, his tongue went dry, and he was drinking from his cupped hands before the analytical framework had finished cataloging the water's mineral content.
They weren't alone.
Three other climbers occupied the cavern's far side. Two women and a man, their gear scarred and patched in the specific pattern of people who'd been climbing hard for a long time. Not a matched partyâthe gear styles were different, the weapons dissimilar, the body language of people who'd grouped up out of necessity rather than choice.
The man noticed them first. Tall, lean, mid-thirties, with a scar that ran from his left ear to the corner of his mouth. He'd been sharpening a short sword on a whetstone, and his hands paused when Noah's party entered the cavern. Not a combat pause. An assessment pause. The kind of stillness that said *I'm deciding whether you're a threat or a resource*.
"Floor 80 clear?" he asked.
"Clear," Marcus said. One word, but the voice carried enough damage that the stranger's eyes went to Marcus's hands, read the swelling, cataloged the injury type. Climbers learned to read each other the way mechanics read engine sounds. The stranger heard Marcus's voice and saw his hands and understood the equation: tough fight, high cost, survivors.
"Took us four attempts," the man said. He set the whetstone down and stood. "Garrett. That's Priya and Song." He indicated the two women. Priya was compact, dark-haired, her arms wrapped in bandage material that glowed faint greenâsome kind of regenerative treatment Noah hadn't seen before. Song was taller, thinner, sitting cross-legged with her eyes closed in a posture that suggested meditation or recovery trance or both.
"Four attempts," Maya said. She'd been quiet since the arena, but the number pulled a response from her the way a specific error code pulled diagnostic output from a monitoring system. "You lost party members."
It wasn't a question. Four attempts at a floor boss meant survivors from failed runs. Garrett's expression shiftedâa tightening around the jaw, a brief focus on the middle distance that Noah recognized as the look of a man glancing at ghosts.
"Seven between the first three runs," Garrett said. "Song and Priya are from my second attempt. We cleared it on the fourth with a temporary allianceânine-person raid group. The other four pushed ahead already."
Seven dead climbers. The number registered in Noah's processing queue as a data point, not a tragedy, and the gap between what it should have been and what it was constituted its own kind of damage report. Seven people who'd climbed eighty floors and died in the attempt to climb the eighty-first. Seven archives of memory and personality and accumulated experience, deleted. Unrecoverable.
He should have felt something specific about that. A version of him from thirty floors ago would have. The current version logged the information and moved to the next query.
"How long have you been resting?" Noah asked.
"Six days. Priya's arms were shatteredâthe Sovereign does that to brawler-class fighters, finds the structural limits of the skeleton and tests them. Song lost her resonance ability completely for the first three days. It came back, but weaker."
"You've scouted ahead?"
Garrett's eyes sharpened. The question had marked Noah as a planner, and planners were either valuable allies or dangerous competitors depending on which side of the equation you occupied.
"Some. Floors 81 through 85 are a gauntletârapid-fire combat floors, no puzzles, no rest between. The Tower compresses the difficulty after a boss clear. Seems like it's testing whether the party that beat the guardian can maintain that level of performance under sustained pressure."
"Can you?"
"Not yet. Priya needs another two days minimum. Song's resonance is at maybe sixty percent." Garrett paused. "There's a shortcut."
The word landed in the cavern and Noah's analytical framework flagged it immediately. *Shortcut* in the Tower's architecture was a loaded term. Shortcuts existedâhidden paths, alternative routes, secret floors that circumvented standard progression. They also served as the Tower's most efficient traps, because a climber willing to take a shortcut was a climber whose decision-making could be predicted and exploited.
"What kind of shortcut?" Maya asked.
"There's a hidden passage on Floor 82. Behind the third wave's spawn point, there's a section of wall that phases if you hit it with dimensional energy. Void Walking, phase shift, anything that operates between standard spatial layers. The passage connects Floor 82 to Floor 87, bypassing five combat floors entirely."
Maya's expression didn't change. Her expression rarely changed during intelligence gatheringâshe processed tactical information the way a server processed queries, with consistent throughput and no visible load on the front end.
"How did you find it?"
"We didn't. A solo climber came through here four days ago. Called himself Renn. He'd mapped most of Floor 82 on a previous attempt and found the phased wall by accident when his partner's ability discharged against it during a fight. Showed us the exact location on his map. Even drew the approach vector."
"Where's Renn now?"
"Pushed ahead. Solo climbers don't rest long."
Noah watched Garrett's face during the exchange and cataloged the micro-expressions. Honesty reads were unreliableâhe'd learned that on Floor 20 with the Crimson Vanguard, where honest-seeming intel had been deliberately constructed misdirection. But Garrett's delivery was consistent. No tells that Noah's pattern-matching could identify. Either the man was telling the truth or he was a better liar than Noah was a reader.
The shortcut information filed itself into Noah's tactical queue alongside a bright red flag: *unverified intelligence from a secondary source describing a convenient solution to a known problem*. In software development, that was the setup for a dependency injection attack. Someone provides a clean, useful library that does exactly what you need, and buried in the code is something that executes when you're not looking.
But the alternative was five rapid-fire combat floors with a party at fifty-five percent.
"We'll consider it," Noah said. The diplomatic non-answer of a project manager who needed to consult his team before committing to an architecture decision.
---
Kira's wound needed more than field medicine.
Maya had been managing it with bandage changes and pressure and the kind of grim efficiency that came from treating injuries when proper medical facilities didn't exist. But the thigh wound from Floor 76âoriginally a deep laceration from a maze construct's blade, aggravated by four floors of combat, reopened during the Mirror Sovereign fightâwas beyond the scope of clean gauze and willpower.
"The muscle is separating," Maya said quietly, her hands steady even as her spatial awareness still stuttered. She was examining the wound in one of the alcoves, Kira lying on the stone platform with her jaw locked in the specific configuration that meant the pain was at a level she wouldn't acknowledge verbally. "The fascia tore during the boss fight. I can keep it clean, but without intervention, the healing process is going to produce scar tissue that limits her range of motion permanently."
"Define permanently," Noah said.
"Sixty to seventy percent of current mobility in the affected leg. She'll compensate. She's already compensating. But compensation costs energy, and energy on higher floors is currency she can't afford to spend on locomotion."
Kira said nothing. Her eyes were on the ceiling, tracking the bioluminescent patterns with the detached attention of someone deliberately placing their consciousness anywhere other than the thing happening to their body.
"Garrett mentioned Tower merchants operate in post-boss zones," Emma said. She'd been hovering near the alcove entrance, her cracked blade leaned against the wall beside her. "If there's a merchant here, they might have something."
"Tower merchants trade in memories and time," Maya said. "I've dealt with them twice. They're fair in the way a vending machine is fairâyou put in the currency, you get the product. No negotiation. No charity."
"What would healing cost?"
"Depends on the severity and the merchant's inventory. Deep tissue regeneration for an injury this advancedâ" Maya glanced at Kira's thigh, at the wound that was less a wound now and more a structural failure in the muscle architecture, "âprobably a significant memory from the patient. A full, intact memory. Not a fragment."
Kira's eyes came down from the ceiling. The look she gave Maya was flat, clinical, the expression of someone performing cost-benefit analysis on their own biography.
"Which memory," Kira said. Not a question. A demand for specifications.
"The merchant chooses. You present yourself, they scan, they name the price. I've never seen a climber successfully negotiate the selection."
Noah watched Kira's face and saw the calculation complete. No visible distress. No weighing of options. The equation was simple: full mobility versus one memory, and for Kira, who operated on efficiency metrics that would make a compiler jealous, the mobility won before the merchant had even been consulted.
"Where," Kira said.
Priya, who'd been listening from two alcoves away, pointed toward the cavern's eastern wall. "There's a passage back there. Leads to a merchant alcove. Song used it three days ago for her resonance treatment."
"What did it cost her?" Noah asked.
Priya's expression did something complicated. "She doesn't talk about it. But she couldn't remember her mother's name afterward. Had to ask me."
The information settled into the alcove like sediment. Kira didn't react. She was already sitting up, swinging her damaged leg off the platform, testing weight distribution with the mechanical precision of someone running hardware diagnostics.
"I'll go," she said.
"I'll come with you," Emma said. Not asked. Stated. The verbal equivalent of placing herself in Kira's path and not moving.
Kira looked at Emma. The look lasted three secondsâlong for Kira, who processed visual information about other people the way high-frequency trading algorithms processed market data, in milliseconds. Three seconds meant she was reading something in Emma that required additional sampling.
"Fine," Kira said.
They left together. Emma's hand hovered near Kira's elbow without touchingâclose enough to catch, far enough to preserve the assassin's dignity. The gesture was more fluent than anything Noah could have managed. Emma spoke the language of physical proximity the way Noah spoke the language of structural analysis, natively and without visible effort.
He watched them go and tested the warmth. Present. Diminished. Real. He could still feel something when he saw his sister caring for someone who'd spent most of her life being cared for by no one.
For now.

David found Noah at the water basin, refilling canteens with the systematic efficiency of someone who'd learned that hydration logistics were the unsexy foundation of sustained survival.
"Can I ask you something?" David's gold lightning flickered between his fingers as he crouched beside the basin. Nervous energy. The sparks were more stable than they'd been before Floor 79âthe gold composition smoothing the discharge patterns, reducing the chaotic arcing that used to accompany David's anxietyâbut the underlying behavior was the same. David sparked when he was processing something that didn't have a clear output.
"Ask."
"During the boss fight. When I went full power. You said 'do it' without hesitating."
"I assessed the tactical situation and determined that your full output was necessary to create the opening we needed."
"Right. The tactical situation." David's sparks intensified, dimmed, steadied. "Did you think about the cardiac risk?"
"I factored it into the probability assessment. One percent failure rate against the certainty of defeat without your contribution. The expected value calculation favored engagement."
"Expected value." David repeated the phrase the way someone repeats a word in a foreign language, testing whether it means what they think it means. "You ran a math equation about whether my heart stopping was an acceptable outcome."
The sentence was accurate. Noah recognized that the accuracy was precisely the problemânot because the math was wrong, but because framing a teammate's potential death as a probability equation was the kind of cognitive output that should have been intercepted by an emotional subroutine before it reached the verbal processing layer. The interception hadn't happened. The subroutine was degraded. He'd said the quiet part loud because the architecture that separated quiet parts from loud parts was developing holes.
"I also didn't want you to die," Noah said. "I said that before the fight."
"You did. And I believed you." David's gold sparks settled into a steady rhythm, synchronized with his breathing, the stable oscillation of a system that had found its operating frequency. "But I'm asking whether the version of you that ran the math and the version of you that didn't want me to die are still the same version. Or whether they're diverging."
The question was surgically precise. David hid his intelligence behind enthusiasm and self-deprecation and pop culture references that nobody in the Tower understood, but underneath the performance was a mind that tracked human behavior with the same rigor Noah applied to architectural analysis. David had noticed the divergence. Had been tracking it. Was asking not because he didn't know the answer but because he wanted to know whether Noah knew.
"They're diverging," Noah said. The admission cost nothing. Not because honesty was cheap, but because the part of him that would have found the admission painful was behind glass now, observable but muted. "The analytical framework is outpacing the emotional responses. I can still feel thingsâconcern, loyalty, the residual warmth of relationships I've invested in. But the feelings arrive slower than the calculations. And sometimes the calculations finish before the feelings start."
David stared at the water basin. His reflection stared back, gold-lit, distorted by the current.
"In the boss fight," David said. "When you said 'do it.' How long between the calculation finishing and the concern arriving?"
"Approximately two seconds."
"And the order came out at the one-second mark."
"Yes."
David nodded. The nod was small, contained, the gesture of a man adding a data point to a model he was building privately. He didn't look angry or hurt or afraid. He looked like someone who'd confirmed a hypothesis and was now updating his operating assumptions accordingly.
"Okay," he said. "I need you to know something, then. If the moment comes againâfull power, cardiac risk, the whole dealâI need the order to come from the two-second version. Not the one-second version. I need the Noah who's done the math AND felt the cost to be the one making the call."
"That might mean a slower response time."
"I'll take two seconds of delay over being expendable arithmetic."
The word *expendable* hit a register that the calculation framework couldn't process. It bounced off the analytical layer and landed somewhere lower, somewhere pre-cognitive, somewhere the Hollowing hadn't fully mapped. Not an emotion. A physical response. A tightening in Noah's chest that wasn't cardiac and wasn't respiratory but occupied the same anatomical neighborhood.
"You're not expendable," Noah said. "In any version."
David's gold sparks flared onceâbright, warm, the color of something being forged rather than burnedâand settled back to their baseline rhythm.
"Good," he said. "Because I'm going to hold you to that."
---
Emma returned without Kira forty minutes later. Her face carried the specific tightness of someone who'd witnessed something they couldn't intervene in, the expression of a bystander at a transaction where the currency was human.
"The merchant took her memory of learning to throw a knife," Emma said. She sat beside Noah in the alcove he'd claimed, close enough to touch, not touching. "Not a specific throw. The muscle memory of the first time a blade left her hand and hit a target. The foundational throw. Everything she's built on top of it is still thereâthe technique, the accuracy, the speedâbut the root of it is gone."
"Will it affect her combat performance?"
"Maya says no. The skill is in the body, not the memory. But Kiraâ" Emma's hands opened and closed in her lap, the physical expression of something she couldn't organize into words. "She sat there while the merchant worked, and when it was done, she threw a knife at the wall. Perfect form. Dead center. And then she looked at the knife like she'd never seen one before. For about three seconds, she didn't know why she was good at what she was good at."
"Three seconds."
"Then it passed. The body knew what to do even when the mind forgot why. She pulled the knife out and threw again and it was fine. She's fine. The wound is healingâactually healing, not just stabilizing. The merchant's treatment is working." Emma paused. "But those three seconds, Noah. She looked lost. Kira. The most self-certain person I've ever met. Lost."
Noah processed the information and filed it alongside his own experience of the Hollowingâthe sprinkler memory, hollow but intact, the image without the joy. Kira's version was different. Hers was the skill without the origin. The output without the initialization function. A program that ran correctly without any record of being compiled.
"She'll adapt," Noah said. "The body retains what the mind releases."
"Is that how it works for you?"
The question was a targeted probe. Emma asking not about Kira but about Noah, using Kira's experience as a proxy to access information her brother's increasingly clinical delivery made difficult to extract directly.
"My losses are emotional, not procedural. The skills remain. The analysis remains. What degrades is theâ" he searched for the right framework, the metaphor that would make the architecture of his deterioration comprehensible, "âthe commenting in the code. The documentation that explains why a function exists. The code still runs. But the comments that said *this function matters because* are being stripped out line by line."
Emma was quiet for eight seconds. He counted.
"Tell me a story," she said.
"You tell the stories. I'm the one whoâ"
"No. You tell me one. Something from before. Something you still have."
The request inverted their established pattern. Emma rebuilt his memories by telling stories from her archive. She hadn't asked him to access his own beforeâhadn't pushed him to explore what remained in the unprotected catalog, to test the boundaries of the Hollowing's advance by reaching for material that might or might not still carry warmth.
He went looking.
Past the hollowed childhood memoriesâthe sprinkler, the bike, the graduation, all images without payload. Past the degraded teenage memoriesâhigh school, college applications, the part-time job at the computer repair shop that had started his career trajectory. The degradation pattern was consistent: oldest memories hit hardest, recent memories relatively intact, the erosion advancing like a formatting operation working from sector zero toward the present.
He found one. A fragment from college. Sophomore year, maybe. The context was fuzzyâthe surrounding memories had been consumed in various micro-activations, leaving this one isolated, a data point without adjacent entries. But the memory itself was sharp. Intact. Warm.
"I was debugging a project at two in the morning," he said. "Server room in the CS building. The project was due at eight. The code wouldn't compile and I'd been staring at it for six hours and I couldn't find the error."
Emma leaned her head back against the alcove wall. Listening. The specific stillness of someone receiving something they'd asked for.
"Emma called me. Two AM. She was fourteen. She said she couldn't sleep and she wanted to know what I was doing. And I told herâI told youâI was trying to find a bug in a program, and you asked what a bug was, and I explained it, and you said, 'Have you tried turning it off and turning it on again?'"
Emma's mouth twitched. The smallest motion, the muscular precursor to a smile that she held in check because the moment was too fragile for a full expression.
"I laughed," Noah said. "I'd been staring at that code for six hours and you made me laugh with the most basic troubleshooting advice in existence. And then I restarted the compiler. And the code ran. The bug was a cached error from a previous build that the compiler was holding onto. You were right. Turn it off and on again."
"I remember that call," Emma said. Her voice was careful. Controlled. The voice of someone building a bridge between their memory and his, matching the materials so the connection would hold. "You sounded so tired. And so surprised when it worked."
"The memory is warm," Noah said. "The warmth is real. Not reconstructed. Not borrowed from your telling. This one is mine."
Emma's hand found his in the space between them. Her fingers were calloused, rough, the texture of a blade dancer's grip mapped across her palm in patterns that told the story of eighty floors better than any system notification. She squeezed once. Hard. The pressure communicated more than dialogue could have carried.
They sat in the warm blue-white light of the cavern and held the memory between them like a physical object, a thing with weight and edges and warmth that existed in both their archives simultaneously, cross-referenced, verified from two independent sources.
---
Kira returned walking on her own.
Not limping. Not compensating. Walking with the full, clean stride of someone whose leg muscles were operating within normal parameters for the first time in four floors. The Tower merchant's treatment had done what Maya's field medicine couldn'tânot just stabilized the injury but reversed the tissue damage, rebuilt the separated fascia, restored the structural integrity of the leg from the inside out.
She crossed the cavern to where Maya was sitting against the basin wall, her spatial equilibrium still recalibrating, her hands still trembling when she reached for objects that were slightly farther away than her disrupted depth perception predicted.
"Maya."
"How does it feel?"
"Functional." The word was different when Kira used it. Marcus said *functional* as a minimum viable status report. Kira said it as the highest compliment her vocabulary permitted for her own body. "The merchant's treatment is thorough. The regeneration extends beyond the primary injury siteâit addressed the secondary inflammation and the bone bruising from the compensatory stress patterns."
"Good."
Kira sat down beside Maya. Close. Closer than Kira typically positioned herself relative to anyone. The distance between them was less than the fifteen centimeters Emma had maintained with Noahâthis was maybe five centimeters, an encroachment on personal space that from Kira constituted a statement.
"I lost the first throw," Kira said. "The memory of it. Learning. The instructor's hand on mine, correcting the grip. The target twenty feet away that looked like it was twenty miles."
Maya didn't respond immediately. She let the silence exist the way she let void space exist during dimensional shiftsâas a medium, not an absence.
"Do you miss it?"
"I don't know how to miss something I can't remember having. I know the memory existed because the gap has a shape. Like a tooth socket. The architecture around it still references something that used to be there." Kira paused. "Is that what Noah feels?"
"Ask him."
"I'm asking you."
Maya's trembling hands stilled. The question had redirected her processing from her own spatial dysfunction to a query she could address with accumulated data. She'd been observing Noah's deterioration longer than anyone except Emma. Her observations were clinical by nature, filtered through the survival calculus that governed all her analysis, but they were thorough.
"What Noah feels is more extensive. Your loss is a single memory, surgically removed, with the surrounding context intact. His losses are cumulative. Layered. The emotional content is stripped from memories that remain visually present. Imagine your knife throw memory still existingâyou can see the instructor, see the target, see your fourteen-year-old hand gripping the bladeâbut the feeling of learning, the satisfaction of the first successful throw, the attachment to the skill's origin, all of that is gone. The memory becomes a photograph. Evidence that something happened, with no emotional connection to the event."
Kira absorbed this. Her face didn't changeâKira's face was a static deployment, consistent across input typesâbut her hand moved to the knife on her belt. Touched the handle. The fingers found the grip with perfect, practiced precision, muscle memory executing flawlessly, the body knowing what the mind no longer remembered learning.
"The gap has a shape," she said again. Quieter this time. To herself.
---
Garrett found Noah at the cavern entrance three hours into their rest period. Noah had been calculating. Not tactics or Path Sight projections or party optimization models. He'd been calculating the number. The one that mattered more than any other parameter in his operational framework.
Remaining Path Sight activations before hard capacity.
The math was imprecise because the variables were imprecise. Memory density varied. The Hollowing's targeting algorithm was adaptive, not linearâit went after the highest-value memories first, which meant early activations consumed more cognitive data per use than later ones would, when the premium memories were exhausted and the system had to settle for lower-density material. The ten Bastion memories were excluded from the calculation entirelyâprotected, untouchable, a fixed allocation that reduced the available pool but didn't degrade over time.
His best estimate: three hundred and twelve micro-activations remaining. Or thirty-one full activations. Or some combination of both. Plus or minus fifteen percent based on the density variance of his remaining unprotected archive.
Three hundred and twelve uses of the ability that defined his climbing identity. After that, Path Sight went dark. Permanently. No more golden lines. No more optimal routes. No more seeing what others couldn't.
The number was finite in the way that terminal diagnoses were finite. Not a death sentenceâhe'd still be alive, still be climbing, still be a party member with analytical skills and strategic value. But the thing that made him *the Pathfinder* had an expiration date, and he'd just gotten close enough to read the numbers on it.
"Your party's in rough shape," Garrett said, leaning against the corridor wall opposite Noah. The scar on his face caught the bioluminescent light and turned silver. "Worse than you're letting on."
"We're managing."
"You're calculating. I've been watching you since you arrived. You sit apart from your group and you run numbers in your head and every few minutes your eyes unfocus in a way that says the numbers aren't coming out the way you want them to."
Noah evaluated the observation and found it uncomfortably accurate. Garrett was a reader. Not the emotional intuition typeâthe behavioral pattern recognition type. He watched how people moved, where they sat, what their eyes did when their conscious attention was elsewhere. Intelligence gathering through passive observation. The skill of someone who'd survived multiple failed climbs by knowing more about his environment than his environment knew about him.
"The shortcut you mentioned," Noah said. "The phased wall on Floor 82."
"What about it?"
"You said a solo climber named Renn mapped it. Renn's gone ahead. We have his information but no way to verify it independently."
"Correct."
"And you trust it."
Garrett's hand went to his scar. An unconscious gestureâthe kind of self-touch that accompanied memory access, the body's physical bookmark for a stored experience. "Renn showed us the map. The detail was consistent with someone who'd actually been inside the passage. He described the phased wall's texture, the corridor beyond it, the specific dimensional frequency required to activate the phase. The information is either genuine or it's the most elaborately constructed false intelligence I've encountered in eighty floors."
"Those aren't mutually exclusive."
Garrett's mouth moved. Not a smile. The muscular configuration of someone acknowledging a point they'd already considered and filed under *acceptable risk*.
"No," he said. "They're not. But my party needs those five floors bypassed more than yours does. Priya can't fight consecutive combat floors. Song's resonance won't sustain a gauntlet. The shortcut is our best option for reaching Floor 87 intact."
"When do you move?"
"Tomorrow. My party's resting another twelve hours, then we advance to Floor 82 and test Renn's map." Garrett straightened from the wall. "You could come with us. Nine bodies on a hidden path are harder to ambush than three."
The offer was tactically sound. Combined party strength, shared risk, complementary abilities. Noah's Path Sight could verify the hidden passage's legitimacyâone micro-activation at the phased wall to check whether the golden lines confirmed or rejected the route. The cost of a single activation against the savings of skipping five combat floors.
The equation balanced. The equation almost always balanced. That was the problem with equationsâthey optimized for the variables you included and ignored the ones you didn't.
"We'll discuss it with the team," Noah said.
"Fair. The offer stands until we move." Garrett turned to leave, paused. "Your Pathfinder. The thing with the golden lines. I saw you use it during the arena fight when you thought nobody was watching. The way your eyes changed. The way you moved differently for about half a second."
Noah's body went still. The stillness of a system encountering an unexpected inputânot frozen, but processing, allocating resources to evaluate a potential threat.
"Everyone's got secrets in the Tower," Garrett said. "Yours is more visible than you think."
He walked back into the cavern. Noah stayed at the entrance and tracked Garrett's movement across the space, watching the way the man navigated between his own party members and Noah's with the careful path selection of someone who knew exactly where every person in the room was standing.
The developer's brain ran a rapid threat assessment. Garrett had identified Path Sight from behavioral observation alone. He knew what Noah could do, approximately how it worked, andâcriticallyâthat Noah was trying to conceal it. That information in the wrong hands, on the wrong floor, sold to the wrong faction, could convert the party's strategic advantage into a targeting vulnerability.
But Garrett had shared the information openly. Told Noah that he'd noticed, that the secret wasn't as secure as Noah believed. That was either genuine transparencyâa fellow climber extending professional courtesyâor the most sophisticated piece of social engineering Noah had encountered since the Tower began.
And the shortcut information sat in his tactical queue, bright and useful and unverified, the exact shape and size of something too good not to use.
Noah closed his eyes and ran the final diagnostic of the day. Memory Bastion: intact, all ten protected. Unprotected archive: degrading at projected rates. Path Sight remaining: approximately three hundred and twelve activations. Party status: recovering. External threat assessment: inconclusive.
Somewhere in the cavern behind him, Emma was talking. He couldn't make out the words, but the cadence was familiarâthe rhythm of stories being told, memories being built, bridges being constructed between a sister's archive and a brother's diminishing capacity to hold what she was giving him.
He listened to the rhythm and tried not to calculate how many stories they had left.
From somewhere deeper in the cavern, past the alcoves and the water basin and the soft blue-white light, a sound reached him. Metallic. Regular. The unmistakable rhythm of someone sharpening a blade.
