Night never truly reached Ironreach.
The smoke never allowed darkness to settle completely.
Instead, the city existed in a permanent twilight—half-lit by burning factories and distant artificial suns from the Celestial Ring above.
Kael stood at the edge of the warehouse balcony, staring into the haze.
Tick.
Steady.
But deeper than before.
The connection hadn't faded since the battle.
Since Riven.
Since the Engine had reached back.
If anything—
It had grown stronger.
Lyra stepped beside him, arms folded against the cold wind.
"You felt it again, didn't you?"
He nodded.
"It's closer."
Her expression tightened.
"That's impossible. The Engine is kilometers below the underlayer."
Kael shook his head slowly.
"No… something else is."
Inside the warehouse, a Syndicate scout burst through the doors.
Breathing hard.
Covered in soot.
"We found it," he gasped.
Riven looked up from cleaning dried blood off his gauntlets.
"Found what?"
The scout swallowed.
"A Church excavation site. Deep under Sector Nine."
Lyra froze.
"Excavation?"
"They've been digging for weeks. Hidden operation. We only noticed after the last quake."
Kael felt it instantly.
The pull in his chest sharpened.
Tick.
Louder.
"That's where it is," he said.
Lyra turned to him slowly.
"What is?"
Kael met her gaze.
"The thing calling me."
The descent into the underlayer took hours.
Ironreach slowly gave way to rusted tunnels, abandoned transit shafts, and forgotten maintenance corridors.
Civilization thinned.
Then vanished.
Only echoes remained.
Riven led the way with a portable floodlamp, its beam cutting through thick dust and steam.
"This place gives me nightmares already," he muttered.
Lyra scanned the walls, eyes wide behind her lens.
"These tunnels predate the city… predate the Church."
Kael ran his hand along the metal wall.
It vibrated faintly.
Like distant thunder.
Tick.
The rhythm matched.
They finally reached it.
A massive reinforced blast door.
Half buried in rock.
Church insignia etched across its surface.
Recently opened.
Riven whistled softly.
"Well… that's definitely not suspicious."
Lyra approached slowly, studying the markings.
"These seals are new. They've only just broken through."
Kael stepped closer.
The ticking surged.
Tick.
Tick.
Tick.
His chest burned.
"It's behind this," he whispered.
Riven pushed the door.
It groaned open.
A gust of ancient air rushed out.
Cold.
Dry.
Dead.
The chamber beyond dwarfed anything they had seen before.
A cavern carved by impossible machinery.
Walls lined with enormous, unmoving gears fused into the rock.
Pillars thicker than skyscrapers disappeared into darkness above.
Lyra's voice trembled.
"This… isn't part of the Engine."
Kael shook his head slowly.
"No."
"It's older."
In the center of the chamber stood a structure.
A tower of black metal and glass.
Smooth.
Unscarred.
Untouched by time.
Unlike everything else in the city.
It looked new.
Perfect.
Waiting.
Riven frowned.
"Tell me that's not a door."
Lyra scanned it.
Her lens flickered violently.
"I'm not reading any energy source."
Kael stepped forward.
"But it's active."
He could feel it.
Calling him.
The ticking thundered.
Tick.
Tick.
Tick.
As he approached, the black surface rippled slightly.
Like liquid metal reacting to his presence.
Lyra grabbed his arm.
"Kael, wait. This could be a trap."
He didn't stop.
"It's been waiting longer than the Church."
The tower hummed.
Soft.
Resonant.
Ancient.
Symbols began to appear across its surface.
Not Church script.
Not modern language.
Something older.
Lyra stared in shock.
"This predates recorded history…"
Riven crossed his arms.
"Great. Ancient mystery door. Exactly what we needed."
Kael reached out.
His hand hovered inches from the surface.
Tick.
The rhythm aligned perfectly with the structure's hum.
Lyra whispered—
"Don't."
He touched it.
The reaction was immediate.
The chamber shook violently.
Dust rained from the ceiling.
The black tower split down the center.
Panels sliding apart with silent precision.
Revealing—
A doorway.
Pitch black inside.
Endless.
Lyra stepped back.
"That's not possible…"
Kael stared into the darkness.
He felt something he had never felt from the Engine.
Not curiosity.
Not calculation.
Recognition.
A voice echoed from within.
Not mechanical.
Not human.
Ancient.
"Welcome back."
Lyra grabbed Kael's arm.
"You heard that too, right?!"
He nodded slowly.
Riven drew his weapon.
"Yeah. I hate this place."
The darkness inside the doorway shifted.
Shapes moved.
Slow.
Massive.
Something stepped forward—
Then stopped at the threshold.
A silhouette.
Human in shape.
But wrong in scale.
Too tall.
Too still.
Its eyes opened.
White.
Blinding.
Lyra gasped.
"That's impossible…"
Kael couldn't breathe.
Because he understood.
Not logically.
Instinctively.
This place.
This structure.
This thing.
They weren't made by the Church.
They weren't made by the city.
They were here first.
Before the Engine.
Before civilization.
Before everything.
The figure spoke again.
"Prototype Noctis."
Kael's chest tightened.
Tick—
"You are late."
The chamber trembled again.
Behind them, alarms suddenly echoed through the tunnels.
Church forces.
Closing in.
Lyra turned in panic.
"They followed us!"
Riven cracked his knuckles.
"Of course they did."
Kael didn't look away from the doorway.
"What is this place?" he asked softly.
The figure tilted its head.
"The first interface."
Silence fell like a hammer.
Lyra whispered—
"No…"
Kael stepped forward.
"What happens if I walk through that door?"
The glowing eyes stared into him.
Unblinking.
Endless.
"You remember."
The word hit harder than any weapon.
Behind them, distant gunfire echoed.
The Church was coming.
The war was reaching the depths.
Lyra grabbed his hand.
"Kael, we need to go. Now."
He hesitated.
The doorway pulsed.
Calling him.
Inviting him.
Promising answers older than the city itself.
Riven shouted from the tunnel entrance.
"They're almost here!"
Kael looked once more into the darkness.
Then stepped back.
"Not yet," he said.
The glowing eyes dimmed slightly.
"You will return."
The doorway sealed silently.
The chamber fell still again.
But nothing felt the same.
As they retreated into the tunnels, Lyra's voice shook.
"That wasn't the Engine."
Kael nodded.
"No."
Riven glanced back nervously.
"Then what the hell was it?"
Kael looked down into the unseen depths beneath the city.
Tick.
Steady.
Ancient.
"The thing that built it."
Far above, in the Celestial Ring—
Archon Vire received the alert.
His calm expression finally cracked.
"The Underlayer Door has opened?"
Silence filled the chamber.
For the first time—
Fear touched his voice.
"Accelerate Phase Three."
Back in the tunnels, Kael walked in silence.
The war above.
The Church below.
And now—
Something older than both.
Waiting.
Remembering.
Calling him home.
Tick.
Tick.
Tick.
And the door beneath the city—
Had recognized him.h
