We departed from the Kingdom of the Cyclopes the day after the stone's incorporation.
There was no farewell ceremony. Only the king received us briefly in the main hall, confirmed that the routes were secure up to the mountain limits, and wished that we would return with answers.
Answers.
That was what we needed now.
The sword remained at my waist. No visible alteration. No unexpected reaction during the night. I slept with my hand close to the hilt, attentive to any change. Nothing happened.
We descended the stone trails at dawn. Rai'kanna led, steps firm, evaluating the terrain with the trained eye of someone born in mountainous territory. Elara maintained constant attention to the mana flow around us. Vespera walked in silence, bow ready, as if anything could emerge from the rock crevices at any moment. Liriel and Lyannis walked close behind me.
The air grew more humid as we descended.
"There is something different," Elara murmured after a few hours.
"Mana?" I asked.
"Not exactly. It's… absence."
Rai'kanna stopped.
"Explain."
"The natural flows are weaker here."
Liriel closed her eyes for a moment.
"She is right. The light meets no resistance. Only emptiness."
I looked around. The landscape was the same: high rocks, sparse vegetation, ancient trails. Nothing indicated abnormality.
"Could it be demonic influence?" Lyannis asked.
"I sense no direct presence," Liriel replied. "But something interfered."
We continued descending until we reached a rocky plain marked by deep fissures. The wind blew upward, carrying a distant, almost imperceptible sound.
I stopped.
"Did you hear that?"
Vespera tilted her head.
"Yes."
It was a rhythmic sound.
Not natural.
I approached the edge of one of the fissures. I looked down. The depth was too great to see the bottom clearly.
The sound came from there.
Rai'kanna approached.
"It's not the wind."
"No."
Elara concentrated mana at her fingertips and projected a small luminous sphere into the fissure. The light descended slowly.
For a few seconds, nothing but uneven rock.
Then we saw.
Structures.
Not natural.
Carved.
"Underground construction," Lyannis said.
"It wasn't on the maps," Rai'kanna added.
The sound repeated.
Constant rhythm.
Like metallic beats.
Vespera adjusted her bow.
"Do we enter?"
I observed the opening.
If this were a demonic base, we would be descending directly into enemy territory.
If it was something else, ignoring it could cost us later.
I looked at Liriel.
"Do you feel corruption?"
"No direct. But the absence remains."
I decided.
"We descend."
We used ropes tied to solid rock outcrops. The descent required care. The sound became clearer as we approached the bottom.
Metallic beats.
Constant rhythm.
When we touched the ground, the temperature was lower. The space was wide, a corridor carved into the rock extending ahead.
No demonic symbols.
No signs of recent battle.
Only ancient architecture.
"This is not the work of the cyclopes," Rai'kanna stated.
"Nor of the demi-dragons," she added.
We advanced.
The corridor led to a larger chamber. In the center, a metallic structure was fixed to the floor, connected to stone pillars by thick chains.
And that was where the sound came from.
An internal piece moved, rotating slowly, driven by invisible energy.
"It's a mechanism," Lyannis said, approaching cautiously.
"Powered by what?" Vespera asked.
I approached.
The air there was strange.
No smell.
No perceptible mana flow.
Only function.
I touched the surface of the metal.
Cold.
Ancient.
Elara examined the base.
"There's an inscription here."
I knelt beside her.
Fine symbols, almost erased by time.
Liriel came closer.
"This is ancient language."
"Can you read it?" I asked.
She lightly touched the inscriptions.
"Not completely. But I recognize fragments."
"And?"
She took a deep breath.
"'Seal of Containment.'"
Silence filled the chamber.
I looked at the central mechanism.
"Contain what?"
Rai'kanna approached the structure, evaluating the chains.
"They are tensioned."
The metallic sound repeated.
Stronger.
Vespera took a step back.
"This doesn't look abandoned."
Elara ran her hand over another part of the base.
"There's a recent rupture here."
I approached.
She was right.
A small crack in the structure, as if something had been forced from the inside out.
My instincts went on alert.
"Step back."
Too late.
The central mechanism stopped.
The sound ceased.
The silence that followed was heavy.
Then the crack in the base began to expand.
There was no explosion.
Only cracks slowly spreading across the structure.
The chains vibrated.
Rai'kanna drew her swords.
Vespera already had an arrow ready.
Elara concentrated mana.
Liriel raised her hand, light prepared.
The stone in my sword remained silent.
The structure finally gave way.
Part of the metal fell into the fissure.
And from within it emerged something.
It was not a complete creature.
It was a dark, dense mass, without a defined shape.
It did not exude the usual demonic aura.
It was different.
Older.
Denser.
"This was sealed," Liriel murmured.
The mass moved.
It did not advance immediately.
It seemed to test the space.
I raised the sword.
"Formation."
Rai'kanna advanced from the left.
Vespera positioned herself behind.
Elara and Lyannis prepared support.
The mass sent a dark extension toward Rai'kanna.
She cut.
The blade passed through.
But the matter simply reformed.
"It's not physical," Elara said.
Liriel projected a beam of light.
The energy hit the mass.
There was a reaction.
A recoil.
No clear damage, but resistance.
"It works," she affirmed.
"Then maintain pressure," I replied.
I advanced.
I made a direct cut.
My blade passed through the mass.
At the moment of contact, I felt something different.
A slight vibration.
Almost imperceptible.
The stone reacted.
Not with light.
Not with sound.
But with density.
The dark mass hesitated.
For a fraction of a second, it lost cohesion.
Rai'kanna noticed.
"Now!"
She struck the unstable point.
This time, part of the mass disintegrated.
Not completely.
But it did not reform.
Vespera fired.
The arrow passed through the weakened area.
More fragments were destroyed.
The creature retreated.
It tried to withdraw into the fissure.
I did not allow it.
I advanced again.
I channeled mana precisely.
The vibration in the sword became clearer.
The next cut was different.
The blade met resistance.
And passed through.
The mass split.
Part of it evaporated like dispersed smoke.
The remainder abruptly withdrew into the fissure.
Silence.
The chamber stood still.
The mechanism was destroyed.
The fissure remained open, but inactive.
I took a deep breath.
Rai'kanna observed the space carefully.
"Was it destroyed?"
"Not completely," Liriel said. "But weakened."
I looked at my sword.
Now there was something different.
Subtle.
A sense of alignment.
The stone was no longer completely silent.
It reacted.
Not as an explosion.
But as adjustment.
Elara approached.
"Did you feel it?"
"Yes."
"Then it works."
I nodded.
It was not proof against a general.
But it was evidence.
The stone interfered with the cohesion of what was sealed.
Lyannis observed the fissure.
"If this was a seal… someone broke it."
"Or the seal weakened," Vespera said.
I looked around.
Ancient structure.
Deteriorated mechanism.
Something contained there for an indeterminate time.
And now, partially released.
"We cannot leave this open," Rai'kanna said.
Liriel nodded.
"I can reinforce it temporarily."
She raised her hands.
Light concentrated on the fissure, creating a stable luminous barrier.
"This is not permanent," she warned.
"It doesn't need to be," I replied. "But now we know."
I sheathed the sword.
The stone reacted.
Not with spectacle.
But with precision.
We left the chamber in silence.
Upon reaching the surface again, the wind felt lighter.
The underground sound had ceased.
I looked at the horizon.
The world continues moving.
Ancient seals break.
Forgotten things awaken.
But now I have something different on my blade.
Something that does not manifest until the exact moment.
And today, for the first time, it responded.
The underground call was silenced.
And doubt began to turn into certainty.
