The safe house smelled like stale coffee and old paper. Sera was on the cot, propped up against the wall with a thin blanket over her legs. Her face was pale, the kind of pale that wasn't just from lack of sleep. It was a mana-drain pallor. I'd seen it once before, on a mage who'd tried to channel a spell three ranks above her. She'd spent a month in a recovery ward.
Sera's eyes tracked me as I set a cup of water on the crate beside her. She didn't reach for it.
"Twenty hours," I said. My voice was too loud in the quiet room.
"On the shield," she finished. Her voice was flat. Tired. "I know. I can see the timer on my end of the link. It's… distracting."
I pulled up my Codex. The numbers hadn't changed.
**[Codex Panel — Active Transcripts]**
Skill: Ink Shield (D-rank)
Source: Ink Welder
Time Remaining: 19:58:12
Permanent Inscription Condition: Land killing blow on higher-rank target.
"The target's on Floor Three," I said. "The Gloom-Stalker. D-rank. Solitary predator. It fits the parameters."
"Ash's team hunts Gloom-Stalker pelts. For cloaks." Sera didn't look at me. She was staring at the water stain on the ceiling. "They'll be there. Probably today."
"I know."
"You have a plan?"
"I'm working on it."
A long silence. The kind that stretches and gets heavy. Then she spoke, and her voice was different. Not tactical. Not tired. Just… empty.
"I ran the numbers, Liam."
I waited.
"The resonance drain. It's not linear. It compounds with my own expenditure." She finally turned her head. Her eyes were too bright. "If we keep going like this—you fighting, me bleeding mana through this link every time you push a skill—I'll drop below C-rank effectiveness in three weeks. Maybe less. I'll fail my next Mage certification assessment. Lose my guild affiliation. Everything I've built. Gone."
I'd run the numbers too. My estimate was four weeks. She was being optimistic.
A folded sheet on the crate beside her cot had two words in her handwriting I caught before she covered it with a hand: *first pen.* She did not explain. I did not ask.
"There's a solution," I said.
"Is there." It wasn't a question.
I sat on the floor, my back against the opposite wall. The concrete was cold. "I've been researching the binding. My sister's log chip. The corrupted sections. I found a reference. One reference. To 'overwriting' Codex pages at higher ranks."
Sera went very still.
"The fragment of your page in my Codex. I think… if I reach D-rank, I might be able to overwrite it. Replace the binding with a normal inscription. A clean link. No resonance drain."
"Might."
"It's the only lead I have."
She closed her eyes for a second. When she opened them, she looked straight at me. "What's the catch? You wouldn't have waited this long to tell me if there wasn't one."
I'd practiced this. In my head. How to say it. But the words felt wrong. "The memory echoes. The ones stored on the fragment page. They're… part of the data structure. Overwriting the page to remove the binding would likely erase them."
I expected anger. Fear. Something.
She just blinked. "That's it?"
"Those are your memories, Sera."
"And they're in my head. Where they belong. Your Codex holding a copy doesn't make them more mine. Erase them. I want my eight percent mana back." She said it like she was ordering a meal. Clear. Direct. No hesitation.
I hadn't expected that. The memory echoes were my only window. Into the gaps in her story. Into the person she was before she became the mage in the gray coat. The flashes of a different city. A younger face. A feeling of cold stone that wasn't from the Library.
"It might not be that simple," I said. "Erase from the page might not be a clean delete. It could… destabilize the original. There's a reason Codexes aren't supposed to hold fragments of other people's pages."
"So find out. Before you try it." She pulled the blanket higher. A dismissive gesture. "But don't take too long."
The trust was thinning. I could hear it in her voice. The professional courtesy was still there, but the underlying assumption—that we were in this together—was fraying. She was calculating her survival. With or without me.
"I will," I said.
"Good." She looked back at the ceiling. "Now go hunt your D-rank. You're wasting daylight."
I stood. Grabbed my pack. At the door, I glanced back. She hadn't moved. Her breathing was shallow. The mana exhaustion was deeper than she was letting on.
"The water's fresh," I said.
She didn't answer.

The Library entrance was its usual chaotic mess. Hunters milling, clerks scanning badges, the low hum of the main gate's containment field. I moved toward the checkpoint board—a massive slab of dark wood where teams posted notices, looking for members, selling loot.
My eyes scanned for Ash's crest. Or Rex's. Nothing.
Then I saw it.
A single sheet of cream-colored paper, pinned to the lower right corner with a plain steel tack. No heading. No signature.
Just a glyph.
A circle, bisected by a single vertical line that flared at the top and bottom. The same glyph from the note in Chapter Eight. The one that had shown up after Sera withdrew.
Beneath it, in neat, handwritten script:
*The Gloom-Stalker is not your path. The walls have ears. The ink has eyes. Your binding is a beacon. They are coming for the source.*
*South spire. Floor Five. Sunset.*
*Come alone. Or she dies with you.*
The paper felt cold. Ordinary. The words didn't shimmer. No mana trace. Just ink.
They knew about the binding. They knew about Sera. They knew I was hunting the Stalker.
*They are coming for the source.*
I crumpled the note in my fist. My Codex flickered at the edge of my vision, a silent pulse. The Ink Shield timer read 19:41:08.
South spire. Floor Five. That was deep. Deeper than I'd ever gone. Deeper than any E-rank had any business going.
Sunset.
I had nineteen hours to inscribe a D-rank shield. Or walk into a trap on Floor Five with a temporary skill and a mage who was running on fumes.
I looked at the board. At the crowds. No one was watching me. Everyone was watching everyone.
*The walls have ears.*
I turned and walked toward the gate scanner. My badge beeped. Green light.
The Gloom-Stalker was on Floor Three. A straight shot. A known variable.
The note was in my pocket. A unknown. A threat.
My hand went to the vial in my coat. Half-full. Purification agent.
I stepped through the gate. The world dissolved into the familiar gray haze of transit.
When it cleared, I was in the C-wing antechamber of Floor Three. The air was cool. Quiet. The way to the Gloom-Stalker's territory was to the left. A three-hour trek through catalog sectors.
I stood there for a full minute.
Then I turned right.
Toward the central shaft. Toward the stairs leading down.
Floor Four. Then Five.
The shield timer ticked down.
*Come alone.*
I checked the knife at my belt. The half-vial. The borrowed access card that still had Sera's clearance.
I started walking.
The walls felt closer than before.
