The first thing I learned about complete darkness was that people became much louder in it.
Not because they shouted.
Because they stopped pretending they weren’t afraid.
Someone behind me stumbled. Tomas cursed under his breath, followed by the scrape of boots against stone. Metal shifted as Mara raised her weapon, and Lyra’s crossbow clicked into position.
Then the key in my pocket turned again.
I caught it through the fabric.
"Nobody move," Mara ordered.
"Excellent advice," I said. "Especially since I can’t see my own hand."
"Can you be quiet?"
"Probably. No promises."
Kaelen stood somewhere to my left. I could hear his breathing, slow and deliberate, the way someone breathed when they were trying to convince themselves that everything remained under control.
The voice came from ahead.
"Kaelen."
He didn’t answer.
"Bring the vessel."
I pulled the key out of my pocket. Even without the lamps, I could see a faint red line running through its black metal.
"Does anyone else find it suspicious," I whispered, "that every ancient thing in this mountain knows our names?"
"Put the key away," Kaelen said.
"Why?"
"Because it’s listening."
I looked at the darkness.
"That’s unfortunate. I was about to complain about the service."
The key suddenly twisted between my fingers.
Pain shot through my palm. I nearly dropped it, but a thin thread of red light shot from its tip and disappeared into the floor.
Something answered beneath us.
A deep metallic click rolled through the passage.
Then another.
The stone beneath my boots trembled.
"That’s the door," Kaelen said.
"Which door?"
"The one I told you about."
"The royal palace is nowhere near here."
"I know."
"Then explain how a door beneath a palace can apparently hear us from inside a mountain."
"I don’t know!"
His voice cracked across the passage.
Everyone fell silent.
A moment later, Kaelen exhaled.
"I’m sorry."
That surprised me more than his outburst.
Before I could respond, a pale blue light appeared beneath our feet.
It spread through the cracks between the stones, tracing a pattern that resembled the branches of a dead tree. The light traveled forward, toward the darkness, then climbed the walls.
The lamps remained extinguished.
Whatever had replaced their light came from below.
And it was getting brighter.
Mara crouched and touched the glowing stone.
"These markings weren’t here before."
"How can you tell?" Lyra asked.
"Because I’ve walked this passage twice. The floor was ordinary stone."
"Twice?" I asked.
"You already heard the story."
"I heard about a mining settlement. You neglected to mention the magical floor."
"I didn’t know about the magical floor."
"Fair enough."
The blue lines converged beneath Kaelen’s feet.
He stepped backward.
The light followed.
His hand went to the scar beneath his shirt.
"No," he whispered.
The voice answered immediately.
"You remember."
Kaelen’s expression changed.
Not confusion. Not fear.
Recognition.
I moved closer to him.
"What do you remember?"
He shook his head.
"Nothing."
"That was convincing."
"I said nothing."
The blue light surged.
For an instant, the passage disappeared.
I saw a corridor lined with white pillars. Soldiers knelt along its walls, their armor stained dark with blood. At the far end stood a young man wearing a crown.
He had Kaelen’s face.
But his eyes were completely black.
The crowned man held a sword against the throat of a kneeling prisoner.
The prisoner raised his head.
It was me.
Then the vision shattered.
I staggered, catching myself against the wall.
The passage returned, along with the cold air and the smell of iron.
"Did you see that?" I asked.
Kaelen stared at me.
"See what?"
Before I could answer, the floor split open.
A narrow line appeared between the stones, running straight down the center of the passage. Something beneath it scraped against the rock.
The crack widened.
Mara grabbed Tomas by the collar and pulled him away. Seris caught his other arm, while Lyra backed toward the group with her crossbow aimed at the floor.
"Move!" Mara shouted.
We rushed toward the passage behind us.
Three steps.
Four.
Then the floor stopped shaking.
The crack remained open, but nothing emerged from it.
Instead, a voice rose from below.
Not the keeper’s voice.
Not the voice that had called Kaelen.
This one was quiet, almost gentle.
"Finally."
The key slipped from my fingers.
It didn’t fall.
It hung in the air above the crack, rotating slowly.
Kaelen grabbed my shoulder.
"Don’t let it open."
"I wasn’t planning to!"
He reached for the key, but a red thread shot out of the darkness and wrapped around his wrist.
His entire body stiffened.
The scar beneath his shirt blazed.
"Kaelen!" Seris shouted.
She lunged forward and caught his other arm.
The red thread tightened.
Kaelen dropped to one knee.
I grabbed the floating key.
The instant my fingers closed around it, the system appeared.
\[Keeper’s Key: Resonance initiated.\]
\[Foreign authority detected.\]
\[Attempting to establish connection...\]
\[Warning: The claimant is not the intended recipient.\]
"Then find the intended recipient," I muttered.
\[Connection rejected.\]
\[Authority conflict detected.\]
\[Emergency ability available.\]
I didn’t wait for the explanation.
"Activate it."
\[Stonehide activated.\]
Gray hardness spread over my fingers and wrist.
The key became suddenly heavy.
I pulled.
The red thread snapped.
Kaelen collapsed against Seris, coughing violently. The key dropped into my palm, and the blue light vanished from the floor.
For several seconds, nobody moved.
Then the voice beneath us laughed.
It sounded almost pleased.
"Not him, then."
A second thread emerged from the crack.
This one reached toward me.
I jumped backward.
Mara swung her blade through it, but the steel passed through without resistance. The thread continued toward my chest.
I raised my hardened arm.
The impact drove me against the wall.
Stonehide held, though the gray layer developed a network of fine cracks.
The thread recoiled.
For the first time, the voice sounded irritated.
"The first vessel has learned to refuse."
"Sorry," I said through clenched teeth. "I’m difficult to work with."
The crack began closing.
The floating key dropped fully into my hand.
Beneath us, something struck the other side of the stone.
Once.
Hard enough to shake dust from the ceiling.
Then silence.
The blue lamps flickered back to life.
Every one of them burned with the same pale light.
Mara lowered her sword cautiously.
"Is it over?"
"I’d appreciate it if nobody asked that question again," I said.
Seris was examining Kaelen’s wrist. A thin red mark circled it, matching the shape of the thread that had held him.
"Can you move your fingers?"
Kaelen did so.
"Yes."
"Any pain?"
"Some."
"That’s not an answer."
"It’s the only one you’re getting."
Seris gave him a look that promised a longer argument later.
I examined the key.
Its raven carving had changed. The bird’s wings were now spread, and a tiny inscription had appeared beneath its claws.
I couldn’t read it.
Naturally, the system could.
\[Inscription translated.\]
\[THE FIRST DOOR REMEMBERS ITS MASTER.\]
I stared at the message.
"That’s not ominous at all."
Kaelen rose slowly.
"Show me."
I handed him the key.
The moment he touched it, the inscription vanished.
He dropped it as though it had burned him.
"Don’t give it to me again."
"Wasn’t planning to."
Mara stepped between us.
"We need to reach the surface. Now. Whatever is happening here, we have no way to fight something beneath the mountain."
"Agreed," Seris said.
Lyra glanced toward the passage ahead.
"Then why are we still standing here?"
Nobody had a good answer.
We started walking.
This time, Mara kept everyone close together. Seris and I supported Tomas between us, while Kaelen walked behind us, his sword drawn.
The passage sloped upward.
For the first few minutes, nothing happened.
I almost began to relax.
Then I noticed the footprints.
They appeared in the dust ahead of us, one after another, as though an invisible person were walking just beyond the reach of the lamps.
They were bare footprints.
Small ones.
A child’s.
I stopped.
Mara nearly walked into me.
"What now?"
I pointed.
The footprints continued up the passage.
They were fresh enough that the dust hadn’t settled inside them.
Lyra raised her crossbow.
"Another invisible monster?"
"Hopefully, an invisible child."
"Why would that be better?"
"Children usually have fewer teeth."
Mara ignored us and examined the ground.
The footprints stopped beside the wall.
There, carved into the stone, was a small drawing of a raven.
Someone had scratched a line through its eyes.
Kaelen approached.
His face had gone pale again.
"What is it?" Seris asked.
He didn’t answer.
Instead, he pressed his fingers against the carving.
A section of wall slid inward.
Behind it lay a narrow compartment containing a folded piece of parchment.
Mara reached for it, but Kaelen caught her wrist.
"Don’t."
She stared at him.
"You know what’s inside?"
"No."
"Then move."
He hesitated before stepping aside.
Mara unfolded the parchment carefully.
The handwriting was faded but readable.
She scanned the first few lines.
Then her expression hardened.
"What does it say?" I asked.
She passed the parchment to me.
The message was short.
To the one who carries the raven key:
If the door has called your name, the first seal has already failed.
Do not trust the crowned heir.
Do not trust the vessel.
And above all, do not allow them to stand together when the second door opens.
I read it twice.
Then I looked at Kaelen.
He was staring at the parchment as if he’d seen it before.
"Have you read this?" I asked.
"No."
"Then why do you look like that?"
He swallowed.
"Because I remember writing it."
The passage seemed to grow colder.
Mara snatched the parchment from my hand.
"That’s impossible."
"I know."
"You’ve never been here before."
"I know!"
Kaelen pressed both hands against his temples.
"I don’t remember this place. I don’t remember writing anything. But I know how those words were formed. I know where the ink came from."
His voice fell to a whisper.
"And I know what happened after I wrote them."
Nobody interrupted him.
Kaelen looked at me.
"I killed the vessel."
My hand tightened around the key.
"Which vessel?"
He stared at me for a long moment.
Then his eyes dropped to the raven ring on my finger.
"You."
The system appeared between us.
\[Historical record partially restored.\]
\[Second Door: Seal integrity compromised.\]
\[Projected opening: Unknown.\]
\[Primary condition identified.\]
\[THE HEIR AND THE VESSEL MUST BE SEPARATED.\]
Far below, something began pounding against stone.
Once.
Twice.
Three times.
And from the darkness behind the wall, a child’s voice whispered my name.
