Chapter 23: Walls Within Walls
The paranoid review consumed two days.
I walked every meter of Marlstone's improved infrastructure, examining my constructions through the lens of "what would a magical investigator detect?" The answer was comprehensive and alarming.
The transmuted stones in the gatehouse carried a faint magical signature I'd never bothered to mask — visible to anyone with magical sensing above a certain threshold. The monument cores were positioned with mathematical precision no human builder would achieve naturally, their geometric relationships revealing an underlying system that didn't exist in this world's construction traditions.
The watchtower's observation buff left a detectable residue on anyone who spent significant time within its radius. The granary foundation's stability enhancement was subtle enough to pass casual inspection, but a focused analysis would reveal the impossibility of its effects.
I'd been building carelessly because success had made me comfortable.
[TERRITORY SCAN: ACTIVE]
[VULNERABILITY ASSESSMENT: HIGH]
[DETECTION SIGNATURES: 7 IDENTIFIED]
[AWL: 130/185]
Seven different signatures that a competent magical investigator could identify. Seven threads that a creature like the masked adventurer could pull until my entire operation unraveled.
I cataloged each vulnerability in my coded files and began developing countermeasures.
The cosmetic layer took another week to implement.
I started with the newest constructions — the market shrine's partially completed walls — adding intentional imperfections to mask the underlying precision. Slightly off-center stones. Asymmetrical mortar joints. Cosmetic cracks that looked natural to the untrained eye.
The technique required fighting my own instincts. The system rewarded precision, efficiency, optimal construction. Deliberately building imperfectly felt wrong at a level I could barely articulate.
But the masked adventurer had sensed my precision from a kilometer away. If I wanted to operate without drawing that kind of attention, I needed to learn how to build like a human — flawed, variable, inconsistent.
I also developed a technique for "dirtying" transmuted stone. Mixing ordinary quarry materials with the magically enhanced components reduced their signature dramatically, making the constructions appear mundane to magical sensing. The process cost extra AWL and added time to every project, but it reduced detectability by what I estimated to be sixty percent.
[NEW PROTOCOL: SIGNATURE MASKING]
[AWL COST: +15% PER CONSTRUCTION]
[DETECTION REDUCTION: ~60%]
The tradeoff was acceptable. Invisible progress was still progress.
Torvald represented the internal vulnerability.
He'd noticed the stone quality during the gatehouse construction — asked questions about the unusual transmutation, formed suspicions he'd never fully voiced. Now he was working on the market shrine, handling materials that carried the same signatures he'd questioned before.
I needed to manage him before his curiosity became a problem.
"Torvald." I found him at the quarry site, supervising the latest stone shipment. "I have a proposal."
He turned with the wary expression I'd become accustomed to seeing when I approached him. "Master Garrett."
"Marlstone's construction capacity is expanding faster than my ability to supervise every project. I need someone with authority over stone quality — someone who can make decisions about sourcing, evaluate materials, ensure our constructions meet the standards that have made this town's reputation."
His expression shifted from wary to intrigued. "You're offering me a position?"
"Master Stonemason of Marlstone. Direct authority over all stone-related decisions, a significant salary increase, and a seat at the town's planning meetings." I met his eyes steadily. "You've questioned my methods before. This position would give you the authority to understand them — while also making you responsible for maintaining them."
The calculation behind his eyes was visible. I was offering him power, money, and answers — in exchange for investment in the project he'd been suspicious of.
"I accept," he said finally. "But I want access to your construction notes. The ones that explain how you achieve the quality you achieve."
"You'll have access to everything you need to do the job." Not everything. Never everything. But enough to make him feel trusted, enough to bind him closer, enough to transform a potential threat into a managed asset.
We shook hands, and I added another layer to the walls within walls.
Hild found me at the construction site the following evening.
"A masked adventurer passed through town," she said without preamble. Her scar caught the fading light as she studied my reaction. "I saw her at your workshop door. Friend of yours?"
"No."
"Interesting conversation, though. She stayed a while."
I kept my expression neutral. "She had questions about construction techniques. Adventurers sometimes do — they need to understand fortifications for their work."
"At dawn. Unannounced. With that kind of posture." Hild's eyes held mine without wavering. "The way she moved reminded me of something I saw once, during the border campaigns. An assassin who'd been sent to eliminate our commander."
"She's more observant than I've given her credit for."
"If she'd been an assassin, I'd be dead."
"That's not comforting."
"It wasn't meant to be." I turned back to the construction site, watching workers lay stones that now carried carefully disguised signatures. "She was investigating unusual reports. I explained that our construction methods are unconventional but legitimate. She left satisfied."
Hild didn't respond immediately. When she spoke again, her voice carried the particular flatness of someone filing information for later use.
"The stone quality that Torvald mentioned months ago. The way people seem healthier inside your buildings. The festivals that happen whenever you finish a project. And now a masked adventurer with assassin training, asking questions at your door."
"Coincidences."
"Maybe." She nodded once and walked away, leaving me alone with the construction site and the growing awareness that my file in her mental records had just expanded significantly.
I stayed up all night redesigning my construction protocols.
The new documents incorporated every countermeasure I'd developed — signature masking, cosmetic imperfection, detection reduction techniques. They transformed my building methods from efficient optimization to careful concealment, trading speed for security.
At some point past midnight, I caught my reflection in a dark window. "Garrett" stared back — the face I'd worn for over a year now, familiar enough that I had to concentrate to remember what Spencer Rivera had looked like.
The mask was becoming the default. The identity I'd constructed was settling into my bones, reshaping how I thought, how I moved, how I evaluated situations.
I finished the protocols at dawn, hid them in my coded files, and added one note at the bottom: "Stop building like you're playing a game. This world has eyes."
