The whispers grew louder as they approached the Inner Sanctum.
Kainen could no longer dismiss them as echoes carried through the ancient corridors. They followed the three of them, rising and falling in a language that seemed to press against his thoughts rather than his ears. Sometimes he thought he recognised a word. Each time he tried to grasp it, the meaning slipped away, leaving behind a feeling he could not explain.
Aaron adjusted his goggles. "Tell me you can hear that too."
"I can," Kainen replied.
"Good. I'd be more worried if I were the only one losing my mind."
The Aether God did not react to their exchange. It moved ahead of them, its enormous frame illuminated by the faint blue glow escaping the seams of its armour. Since entering the Spire, it had become increasingly quiet. Whatever memories the place stirred within it, they were not memories it wished to share.
Kainen glanced at its back. "You said this place was a sanctum. A prison. A tomb. Which one is it?"
"All three."
"That doesn't answer my question."
"It is the only answer I possess."
The corridor widened.
Before them stood a pair of doors so tall that their upper edges disappeared into darkness. Unlike the rusted structures they had passed, these doors showed no signs of decay. Their black surface reflected the blue light of the Aether God, but the reflection seemed delayed, as though the metal needed time to remember what stood before it.
Symbols covered the entrance. Some resembled the markings Kainen had found on the buried machine's armour. Others twisted into patterns that made his eyes ache when he stared too long.
At the centre was a circular indentation.
The Aether God stopped.
For several seconds, it simply looked at the door.
"I know this place," it said.
Kainen stepped closer. "From your memories?"
"No."
The machine raised one hand, then hesitated before touching the surface.
"From my absence."
Aaron lowered his lantern slightly. "That is somehow worse."
The Aether God pressed its palm against the indentation.
Nothing happened.
Then the whispers stopped.
The silence arrived so suddenly that Kainen became aware of his own breathing. A faint pressure gathered behind his eyes. His scanner flickered, displaying strings of symbols before collapsing into a blank screen.
A single line of light appeared across the doors.
A voice emerged from the darkness beyond them.
IDENTIFICATION REQUIRED.
Kainen raised his rifle, though he had no target to aim at.
The Aether God remained motionless.
"Designation unknown," it answered.
PURPOSE REQUIRED.
The machine lowered its head.
"I do not remember."
The light across the doors dimmed.
For a moment, Kainen thought the entrance would remain sealed. Then another voice spoke, deeper than the first, carrying a weight that seemed to come from somewhere far beneath the Spire.
MEMORY IS NOT IDENTITY.
The doors began to open.
Cold air spilled into the corridor. It carried no smell of dust, metal, or decay. Instead, Kainen caught a scent he could not place, something clean and unfamiliar that reminded him of rain falling on a world that had never known war.
Beyond the entrance lay an enormous chamber.
Its ceiling vanished into darkness, while thin lines of light traced intricate patterns across the floor. At the centre floated a structure resembling a sphere made from countless interlocking rings. They revolved around an empty space, each moving at a different speed without colliding.
Kainen stared.
"What is that?"
The Aether God stepped across the threshold.
"The archive."
"Of what?"
"I do not know."
Aaron gave Kainen a look. "Our companion really needs to work on his answers."
They entered.
The doors closed behind them without a sound.
Immediately, the sphere stopped rotating.
Every line of light in the chamber went dark.
Kainen turned towards the entrance. "Please tell me that was supposed to happen."
No one answered.
A blue point appeared at the centre of the sphere. It expanded into a thin vertical line, then unfolded into a shape that resembled a human silhouette. The figure had no face. Its outline shifted constantly, as though the chamber could not decide what it was meant to represent.
When it spoke, the voice came from everywhere at once.
AETHER UNIT DETECTED.
The Aether God stiffened.
CLASSIFICATION: FORMER CUSTODIAN. STATUS: COMPROMISED.
Kainen looked at the machine. "Former custodian?"
The silhouette turned towards him.
BIOLOGICAL ENTITY DETECTED.
A cold sensation crawled down Kainen's spine.
UNREGISTERED LIFE. IMPOSSIBLE PRESENCE.
Aaron lifted his weapon. "I don't like being called impossible."
SECONDARY ENTITY DETECTED.
The silhouette faced Aaron.
CONTAMINATION: UNRESOLVED.
"Right," Aaron muttered. "I definitely don't like that."
The Aether God moved between the figure and the two men.
"We seek the Seed."
At the word, the sphere shuddered.
The light returned in brief, uneven flashes. Across the chamber, shapes emerged from the darkness: towering pillars, suspended platforms, and walls covered in carvings that appeared to change whenever Kainen looked away.
The silhouette's head tilted.
THE SEED IS NOT A DESTINATION.
"Then what is it?" Kainen demanded.
ORIGIN. BLUEPRINT. MEMORY.
The words echoed through the chamber.
A DESIGN THAT SHOULD NEVER HAVE BEEN SEPARATED FROM ITS CONSEQUENCES.
The Aether God took a step forward. "Who separated it?"
The silhouette flickered.
For the first time, the voice seemed to struggle.
THE QUESTION IS INVALID.
"Why?"
BECAUSE THE ANSWER IS PRESENT.
Something moved inside the sphere.
Kainen saw it only for an instant: a shape behind the interlocking rings, vast enough to fill the space between them. It was neither machine nor living creature, yet he felt certain that it had noticed him.
Then the chamber's lights went out again.
A sound travelled through the darkness.
Not a whisper.
Not machinery.
A heartbeat.
Kainen's hand tightened around his rifle. Beside him, Aaron stopped breathing for a moment. The Aether God stood perfectly still, its blue core pulsing in time with the sound.
Thump.
The sphere trembled.
Thump.
A thin crack appeared in the empty space at its centre.
The silhouette spoke, but its voice was no longer calm.
INTRUSION DETECTED.
Kainen swallowed. "We already knew someone was trying to reach the Seed."
CORRECTION.
The silhouette turned towards the crack.
THE INTRUSION IS WITHIN THE ARCHIVE.
The Aether God raised its weapon.
"Where?"
For several seconds, the chamber remained silent.
Then the silhouette turned back towards them.
BEHIND YOU.
Kainen spun.
The doors remained sealed. Aaron stood beside him, lantern raised. The corridor beyond the entrance was gone, replaced by a wall of black metal.
Nothing else stood there.
Nothing that he could see.
But in the reflection on the sealed door, Kainen saw three figures.
Himself.
Aaron.
And the Aether God.
Behind them stood a fourth.
It was tall and motionless, its head bent towards Kainen's shoulder as though it had been reading his thoughts.
He turned around.
The chamber was empty.
Then something whispered directly into his mind.
You were never supposed to find us.
The blue light in the sphere died.
And somewhere beneath the Iron Spire, something began to wake.
