The wide metal sheet of the cell door swung back on dry hinges, dragging a heavy crescent path through the loose stone outside.
Inside the vault, the air didn't move. It carried a thick, frosty scent of ancient wood shavings and wet carbon that made Daxian's remaining healthy tissue twitch. He stood on the threshold, the tip of Vesper's sorting rod braced firmly against his boots to keep his balance steady while his eyes pierced the lightless interior.
There were no cages here, nor any standard storage bins for processed metals. Instead, long, parallel rows of heavy timber blocks stretched into the dark, each one weeping a steady, slow line of unaligned ink that pooled in the floor channels.
"We need to grab whatever code-chips are portable and clear the terrace," Vesper murmured, her fingers tapping against her empty canvas pack as she checked the dark path behind them. Her breathing was still shallow from her leg strain, but her gaze remained fixed on the lower quarry floor where the extraction spire pulsed its blue light. "If we take too long checking the heavy components, the dawn cycle will pin us against the wall."
Daxian stepped across the iron sill, his boots leaving dark, wet imprints on the dust-covered floorboards. "We aren't here to scavenge scrap, Vesper."
"Then what are we looking for?"
"A map back up," Daxian said, his left hand reaching out to touch the first timber block.
The rough, un-printed grain felt cold under his fingers, its texture entirely different from the polished jade of Lira's upper pavilion. The Scribble-Tech deep within his marrow didn't violently flash this time. It gave a slow, deep vibration, the black ink beneath his skin rising to meet the weeping fluid of the block like water finding an old channel.
He wasn't merely trying to dodge the next garrison sweep anymore. The realization he had faced out on the terrace had completely shifted his focus. If the collector was hiding these archaic, un-registered materials to build an unauthorized spire right beneath the Father's sight, then the middle tiers weren't an impenetrable fortress. They were a flawed, leaking machine, and the key to rebuilding his own whited-out city was locked inside the very forge that had ruined Bram.
His long-term objective had hardened. He would use the collector's private network to climb back to the Silver-Heights, take the forge owner's resources, and overwrite the system that had un-written his people.
"Look at the markings on the secondary row," Vesper said, her boots clicking softly as she waded deeper into the aisle, her iron rod lifting to point at a sequence of carved runes on a massive stone slate. "These aren't rejected designs for tools. These are structural metrics for an entire administrative floor."
Daxian leaned closer to the stone, his amber eyes tracking the deeply gouged lines.
The text lacked the clean formatting of the standard registries. It was written in a simplified, ancient shorthand that bypassed the typical security firewalls of the upper layers. As his fingers traced the first rune, a sharp, clear memory of Vane's furnace flashed through his mind, followed by three distinct structural coordinates that mapped the internal layout of the collector's private estate above the quarry.
A major obstacle sat right at the center of the coordinate lines—a massive, automated registry block labeled The Filter.
"The filter handles the validation for every piece of material rising from the lower tiers," Vesper explained, her finger following the path on the slate. "If an un-registered signature tries to cross that line, the system doesn't just block the lift. It runs a total structural deletion on the entire shaft."
"Then we don't use the lift," Daxian said.
He turned his focus toward the rear wall of the cell, where a vertical maintenance conduit ran directly through the solid bedrock toward the ceiling of the strata. The pipe was old, its casing made of un-coded iron that showed the same thick layers of oxidation he had broken in the valve station.
"That pipe leads straight into the forge's primary resource reservoir," Vesper noted, her gray eyes narrowing as she connected the dots herself. "It's a direct link, but it's completely flooded with raw, un-filtered processing liquid. Even if your wood graft can take the chemical heat, my leather gear will dissolve before we clear the first hundred yards."
"Then we build an insulation sleeve using the canvas from the camp," Daxian stated, his posture tightening as he took physical charge of the layout. "We use Bram's tools to reinforce the seams, and we move up through the drain before the dawn flush begins."
The goal was clear, and the first major obstacle was mapped. They had a direct path out of the lower garbage tiers, but it required walking straight into the mechanical bloodlines of the man who had ruined the ravine residents.
Vesper stood silent for a moment, her fingers tracing the edge of her respirator mask before she let out a slow, determined nod. "The old man won't give up his tools for charity, glitch."
"He'll give them up when I show him how to un-stitch his jaw," Daxian said.
He reached down, his left hand gripping the edge of the slate block. With a single, heavy surge of his physical strength, he broke the corner off the stone tablet, tucking the small fragment containing the forge coordinates deep into the folds of his white robes. He didn't look back at the dark rows of the archive, nor did he waste time contemplating the scale of the climb ahead.
He strode out of the cell, his boots hitting the gravel terrace with a heavy, purposeful beat that signaled the end of his passive retreat. The hunt was no longer about dodging Krell's hounds; it was about forcing his way up the machine's internal veins, one broken valve at a time.
