Floors Forty through Forty Four were exactly what the Guild records called them.
The Stone Labyrinth.
Not a single floor, but four layers of stone misery stacked on top of each other like the world's cruelest puzzle box.
Each level was its own maze, carved from ancient gray rock and twisted into corridors that doubled back on themselves, dead ends that shifted overnight, and stairways that spiraled down into darkness without warning. Traps were everywhere. Pressure plates. Collapsing ceilings. Walls that sealed shut like jaws. Entrances to the next floor were scattered randomly, sometimes hidden behind false walls or buried beneath rubble, as if the Dungeon itself enjoyed watching adventurers wander in circles until their minds cracked.
For most parties, this place was a slow grind of caution and attrition.
For Damien, it was almost relaxing.
The system map hovered faintly in his vision, marking pathways, elevations, and hostile signatures like a living blueprint. He moved through the maze with the confidence of someone walking through his own house, turning corners without hesitation, stepping over traps without even looking down. His shadows slipped along the walls and ceiling, scouting ahead like silent scouts, feeding him information faster than any normal team could ever gather.
Because he was alone, the Dungeon treated him as a single target. Spawn rates stayed low. No overwhelming hordes. No tidal waves of monsters like the ones expeditions usually triggered.
It didn't seem to register that dozens of shadows followed him like a personal army.
Fine by him.
The terrain itself was the first real threat.
Massive crystal growths burst from the floor and ceiling like frozen lightning bolts, turning wide halls into forests of jagged spears. Light refracted through them in strange, broken angles, scattering reflections everywhere. Silhouettes flickered where nothing stood. Shadows moved when he didn't.
More than one past expedition had panicked and attacked their own teammates here.
Damien understood why.
The deeper he went, the stronger the sensation became.
Something watching.
Something crawling above the lantern's reach.
Not imagination.
Not nerves.
Real.
And it wasn't wrong.
This floor didn't rely on raw strength.
It relied on stealth.
The first time he encountered Prism Leeches, he almost mistook them for distortions in the crystal walls. Translucent, eel like bodies swam through solid stone as if it were water, their forms bending with the light until they were practically invisible. They didn't attack flesh first. They attacked the mind. Once attached, they could scramble thoughts, induce hallucinations, hijack motor control, and if left long enough, completely overwrite a person's consciousness like parasites stealing a house.
For most adventurers, they were a nightmare.
For Damien, they were a joke.
More than once, a leech tried to slip into one of his shadows, only to freeze in confusion. There was no brain to invade. No nervous system. Nothing to latch onto. The moment they realized that, the shadows simply swallowed them whole.
Mind control didn't work on something that technically wasn't alive.
Next came the Crypt Wardens.
Now those were interesting.
They were what Spartoi might become after centuries of evolution. Tall skeletal knights fused with slabs of dungeon stone, their bones threaded with glowing blue crystal veins. Tower shields grew directly from their arms, thick as fortress gates, and their blades looked carved from the same rock as the walls around them.
Heavy. Durable. Brutal.
Yet strangely… honorable.
Damien noticed the pattern quickly. Every time he detected one, it stepped out into the open instead of ambushing. It faced him directly, shield raised, sword ready, like a knight issuing a challenge.
Not once did they try to stab him in the back.
He didn't understand it, but he respected it.
So he gave them clean fights.
Then there were the real problem children.
Gloam Stalkers.
If someone sculpted a panther out of wet basalt and taught it how to hate, it would look like this. Their bodies absorbed light instead of reflecting it, turning them into moving voids in dim corridors. In darkness, they didn't blend in. They disappeared entirely, like holes cut into the world.
They moved with an aura that swallowed sound. No footsteps. No breathing. No scraping claws.
Just silence.
Until something died.
Their claws were long enough to pass for short swords, and their leaps covered entire corridors in a blink. Worse, they hunted in packs. Never one. Never two. The smallest group Damien faced had been five.
Five had already been annoying.
An expedition would be facing dozens.
Maybe hundreds.
Now that would be a bloodbath.
Which was exactly why he'd spent half a day hunting them down.
Floor Forty Three housed their nest. A natural fortress of crystal and stone where hundreds gathered like a living tide of darkness. Watching it from above through his shadows had been like staring into a pit full of moving ink.
But it also handed them the perfect solution.
Magic.
According to Finn and Riveria, these creatures had terrible resistance to large scale spells.
Meaning once the location was confirmed, Riveria didn't need strategy.
She needed artillery.
One bombardment and the entire colony would turn into charcoal.
Damien almost felt bad for them.
Almost.
With the last of the information transmitted through the communication device, he finally descended to Floor Forty Four.
The moment his boots touched the next level, the air changed.
Heat slammed into him like opening a furnace door.
Dry. Suffocating. Heavy.
The cool stone labyrinth vanished behind him, replaced by a breath of burning wind that tasted faintly of ash and sulfur.
Damien exhaled slowly, staring ahead as red light flickered across the tunnels.
"…So this is where the real fun starts."
The Crimson Mountains welcomed him like a blazing maw.
...
The Crimson Mountains lived up to their name in the most cruel way possible.
Breathing alone felt like punishment. Every inhale scraped the lungs raw, thick with heat and ash, as if the Dungeon itself resented being disturbed. Metal armor warmed against the skin within seconds, leather turned damp almost instantly, and sweat formed before Damien had even fully stepped off the stairs.
The stone here was no longer gray. It burned red and black, cracked open by glowing veins of magma that crawled across the ground like slow, living rivers. Heat haze twisted the distance, bending shapes and depth until the eyes could no longer be trusted. A monster thirty meters away might look close enough to touch. A solid stretch of ground could be nothing more than a thin crust over a molten pit.
Mistakes here were fatal.
The space opened up dramatically compared to the floors above. Tight corridors vanished, replaced by massive caverns, jagged cliffs, and natural bridges stretching over chasms that glowed orange far below. Ash drifted through the air like snow falling from a sky that had long since burned away.
This place didn't feel like a maze.
It felt like a battlefield.
There was nowhere to hide.
Navigation itself became a nightmare. Landmarks didn't last. Entire rock formations collapsed or melted away under fresh lava flows. Paths that existed an hour earlier simply ceased to exist. Compasses were useless, spinning wildly due to the Dungeon's interference, and the constant low rumble made it impossible to tell whether something was approaching or if the ground itself was shifting beneath his feet.
Yet none of that was the worst part.
The monsters were.
They were stronger than anything Damien had encountered so far, stronger even than most enemies inside the system dungeons. Excluding The bosses, nothing else compared to the malice that dwelled here.
The first were Cinder Apostles.
Fire elemental humanoids formed from cracked charcoal silhouettes, molten light leaking from within their bodies like blood through broken skin. Their limbs stretched unnaturally long, warped as if shaped from half melted wax. Physical attacks barely slowed them unless their cores were struck, and those cores were buried deep beneath the blazing furnace of their chest cavities. Fortunately for Damien and the expedition, they lacked intelligence. They never coordinated, never formed packs, and fell quickly once he learned to carve precise magical slashes straight into their cores.
Then came the Magma Centipedes.
Huge armored worms that swam through molten rock as if it were water, their segmented bodies harder than steel. Predicting their attacks was the real challenge. They struck from below, erupting from lava with terrifying speed, then vanished again just as quickly. The only warning was vibration, faint tremors that experienced adventurers learned to recognize. One well timed strike was enough to kill them, but hesitation meant death.
Even so, Damien could tolerate them.
What he truly hated were the Furnace Drakes.
They were not true dragons, but winged salamander like beasts the size of warhorses, covered in iron scales that deflected most attacks. Their furnace breath was relentless, and they favored long range harassment, flying high and bombarding targets before retreating. Killing one required an accurate slice through the narrow gap in their neck armor, the single place their scales failed to overlap properly.
The real problem was that they never fought alone.
They flew in packs.
And worse, they were not wild.
They were tamed.
Ash Revenants were the reason expeditions prepared obsessively for the Crimson Mountains. They were once adventurers, their corpses calcified by heat, armor fused permanently to bone, weapons welded into their hands. And unlike most dungeon monsters, they were intelligent. Too intelligent.
They laid traps. They organized ambushes. They tamed Furnace Drakes and rode them into battle. Some wielded ranged weapons. Others used magic with frightening coordination.
As a solo fighter, Damien handled them without much difficulty.
Until Floor Forty Six.
That was where he found it.
A camp.
Not a wandering group. Not a patrol. A full scale encampment. Tents of hardened ash and stone, watch posts carved into cliffs, and lines of Ash Revenants standing in formation. He counted at least two hundred, possibly more. Furnace Drakes circled overhead, over thirty of them, landing and taking off like trained cavalry.
An army.
And Damien knew instantly who it was meant for.
The expedition.
The Dungeon was no longer reacting. It was planning.
He pulled out the communication device Riveria had given him and activated it.
"Riveria, you hear me?"
"Yes," her voice answered, distorted but clear. "The signal is unstable. The mana density here is interfering. I'll need to redesign the device later."
"Save that thought," Damien said calmly. "Get Finn and Gareth to listen too. I've found a problem."
A brief pause, then Finn's voice joined in. "We hear you. We've just entered Floor Forty Three and are preparing to wipe out the Gloam Stalker nest. From your tone, I assume things are worse where you are?"
"Much worse," Damien replied. "Just like you predicted, there's a large scale Ash Revenant force waiting on Floor Forty Six. But the numbers are higher than expected. I'm counting a minimum of two hundred, maybe two fifty. They've got Furnace Drakes as well. I can bypass them alone and reach Floor Forty Seven, but an expedition won't slip through easily. They're positioned perfectly to block you."
Finn exhaled slowly on the other end. "So the Dungeon has finally decided to take us seriously. Still, we proceed as planned."
"Be careful," Damien said. "Even if I hit them from behind with my shadows while you attack head on, I don't trust that this is their full force. They're smart. They'll have something else prepared."
"Oh, they always do," Finn replied calmly. "We've fought them before. I have a guess what they're setting up. Don't worry too much. We'll handle it."
"Good," Damien said. "I'll scout ahead into Floor Forty Seven and see what else the Dungeon is hiding. Let me know when you're close to the camp. I'll come back and support."
"We will," Finn said. "Good luck, kid."
The connection faded.
Damien looked back toward the distant glow of the camp, shadows stirring at his feet, and turned toward the deeper floors.
