Zares’tul observed the early results of his work, unmoved by the satisfaction of completion.
Sentinel I was standing.
It wasn’t a work of art. It wasn’t perfect.
But it was a tool. Another instrument.
A small step in a grand design just beginning to unfold.
The system had provided the basics.
Iron. Quartz. Base energy. Rudimentary components.
But Zares’tul knew it would never be enough.
He had to think bigger—and fast.
Progress couldn’t be reduced to assembling units one by one. That would only stall the conquest he envisioned.
He thought of the world above.
He knew that humanity, even in its primitive state, would eventually reach him.
He had already glimpsed a world that did not understand him—a world that quickly forgot what it could not comprehend.
But he… he would remind them.
The forge.
It was the key—the next logical step in building an empire.
No useless reinforcements. No broad maneuvers without focused objectives.
He had to birth structure at the heart of external chaos.
He needed the means to create effective assault units, but also machines designed to survive.
Zares’tul’s intelligence wasn’t measured by reaction.
It was measured by anticipation.
By recognizing needs before they became urgent.
<blockquote>
Production protocol initiated:
Primary Forge Line – Capacity: Production Unit I
Estimated time: 45 minutes
Resources: 12 iron units / 4 quartz units / 2 energy conversion cycles
</blockquote>
Zares’tul gave the order.
Worker drones moved immediately.
Mechanical arms anchored into cold stone, cutting, shaping, fusing metal structures with hypnotic speed.
But his mind didn’t stop there.
He had other concerns—the surface, the humans, the outside world.
Zares’tul knew his swarm wouldn’t be enough to contain human effort over the long term.
Too slow. Too simple.
He needed a more refined response.
Not just basic sentinels.
Not drones screaming into battle like mindless beasts.
He wanted armor. A veil of metal able to react and strike with precision.
A total blockade—something far beyond mere walls of stone.
He wanted an autonomous force.
A reactive system to intercept humanity’s advance.
<blockquote>
Selected: Deployment of Blockade Unit – Type II
Requirements: Advanced forge + Armor Module I
Estimated time: 2 hours
</blockquote>
The orders were given.
The echo of his thoughts merged with the system’s response.
The forge unit began deploying slowly.
It wasn’t yet a heavy weapon.
Not yet the ultimate armor.
But it was the first shield against future human incursions.
Everything led to the surface.
Zares’tul knew he would have to step out of the shadows.
He would have to strike.
Not yet.
Not without a plan.
He would build, prepare, and soon—test not only materials, but the soul of his empire.
A cold empire. Calculated.
Made of iron and logic.
<blockquote>
Alert: External response detected
Light movement at 600 meters
Probability of intrusion: moderate
</blockquote>
A faint tremor.
You could be reading stolen content. Head to Royal Road for the genuine story.
The intruders were no longer a priority in his calculations—but they were still present.
The time for real confrontation was drawing near.
The forge purred softly.
Not like a typical machine.
It emitted no smoke, no fire.
It pulsed—like a synthetic heart.
Cold. Stable. Precise.
Zares’tul monitored the progression.
Components assembled with flawless efficiency.
Each piece was transported along early-stage magnetic rails built directly into the dungeon walls.
Every plate, every bolt, every wire—aligned to the micrometer.
It wasn’t just construction.
It was a declaration.
Meanwhile, on the surface…
<blockquote>
Movement confirmed – Breach point: Rock fissure D3
Entities detected: 3
Type: Humans – civilian or scout
Equipment: oil torches, supply packs, short blades
Behavior: slow, cautious exploration
</blockquote>
Zares’tul redirected a fragment of his awareness.
The humans had returned.
Not the same as before.
These three wore darker clothing.
Not soldiers. Not miners.
Researchers? Mages? Priests?
Zares’tul didn’t know.
But he knew what it meant:
Rumors were spreading.
Something was sleeping here.
And the humans were starting to listen.
He hesitated.
Should he observe?
Attack?
Capture?
He had only two active Sentinels.
The third was still in production.
And yet, he couldn’t remain passive.
He needed to test fear.
Measure their reaction.
<blockquote>
Order: Activate Indirect Contact Protocol
Module: Recursive Sound Echo I
Effect: amplified vibration, low frequency tone, one-way propagation
Objective: human behavior test
</blockquote>
Beneath the fissure, the ground vibrated.
Not violently.
Just enough to make the stone walls resonate.
A deep, slow pulse.
Three times.
Six seconds apart.
Like a drum from the beyond.
Like a heart that shouldn’t beat.
The three humans froze.
The first raised his torch.
The second placed a hand on the stone.
The third… stepped back.
Zares’tul wasn’t watching their movements.
He watched their heart rates.
Sweat levels. Eye movements.
And the main result was clear:
<blockquote>
Test result: fear induced
Retreat risk: high
Interest in the zone: sustained
Secondary effect: rumor spread likely
</blockquote>
He didn’t kill them.
Not today.
He wanted them to speak.
To tell others what they’d heard.
“We found a fissure. It was breathing.”
He pulled back the echo.
And refocused on his internal structure.
The plan was taking shape.
But the tools were still limited.
He consulted the Nexus.
<blockquote>
Resonance R1 – Available Technologies:
– Primitive Mapping Room
– Subterranean Flow Sensor I
– Reactive Echo Module II (locked)
</blockquote>
The mapping room caught his attention.
It offered no direct combat advantage—
But it would extend his awareness.
Let him understand the underground network.
The natural faults. The resource veins. The weak points.
And more importantly…
He would know where the humans walked.
<blockquote>
Order: Construct Primitive Mapping Room
Cost: Quartz – 3 / Iron – 5 / Energy – stable
</blockquote>
During construction, he felt a familiar tremor from the forge.
The third Sentinel was ready.
It activated without a sound, joining its two sisters.
Zares’tul paused to observe them.
Three entities.
Three extensions of himself.
Not soldiers.
Organs.
Observation tools.
And soon—witnesses.
He thought again of the world.
Not the one of stone and circuitry.
But the world above.
The kingdoms.
The churches.
The mages.
They didn’t know yet.
Maybe they believed something was sleeping beneath their feet—
A spirit. A monster. A god. A curse.
But they didn’t see the truth.
The truth had a shape.
And now, that shape had six legs.
The primitive mapping room took form slowly.
Unlike the forge or the galleries, it wasn’t built to produce.
It wasn’t functional in the traditional sense.
It was a sensory organ.
A center of perception.
And as the central core activated, Zares’tul felt his awareness stretch outward.
Lines appeared in the dark.
Not drawn by hand—
But revealed by the ground itself.
Faults, mineral veins, underground water channels, natural magnetic resonances…
The world beneath the surface was not empty.
It was complex, vibrant—ripe for exploitation.
<blockquote>
Zone scanned: 1.2 kilometers around the Core
Points of interest:
? Collapsed chamber (unknown structure)
? Network of magical roots (stability uncertain)
? Residual energy mark (ancient incantation signature)
</blockquote>
Zares’tul focused on the last one.
A magical signature.
Buried over 900 meters deep.
Far from him—
But still active.
Ancient? Yes.
Understandable? No.
Replicable? Not yet.
He committed the location to memory.
At that same moment, a new signal surfaced.
<blockquote>
Human observation – fissure D3
Source: registered civilian intruder
Report: “Engraving found in the rock.”
</blockquote>
Zares’tul blinked—mentally.
He hadn’t left any engraving there.
He accessed memory streams.
Reviewed drone activity.
Sentinel logs.
Core commands.
Nothing.
No engraving.
<blockquote>
Request: Visual verification via drone – Fissure D3
Initializing…
Captured image: circular engraving on wall
Symbol: Inverted triangle within a circle, surrounded by unknown arabesques
</blockquote>
Zares’tul fell silent.
He hadn’t made it.
But the symbol was there.
And the most troubling part…
It resembled the internal lines of his own Core.
<blockquote>
Data correlation: 71% similarity with Nexus matrix
Origin: unknown
Chance of external tampering: low
Estimated age: > 300 years
</blockquote>
Someone… or something…
had already carved what resembled him—long before his awakening.
And that changed everything.
Zares’tul retreated to the coordination chamber.
Perhaps he wasn’t the first.
Perhaps his arrival wasn’t a coincidence.
But that mystery would wait.
For now, there was a map to expand.
Drones to create.
And a world to build.

He thought he was building in forgotten stone.
But the walls already remembered him.
