The house grew quiet after sunset.
Terrava's twin moons rose slowly above the mountains, their pale light spilling across the mining terraces below.
From his bedroom window, Kael could still see lanterns moving along the ridge where the miners worked to stabilize the collapse.
They were taking it slow.
Too slow.
Which meant the shaft would remain blocked for days.
Kael sat on the edge of his bed, staring at his hand.
The rune had faded slightly since the afternoon, but the faint emerald lines were still visible beneath the skin of his palm.
He turned his hand over.
Still there.
"Definitely not a concussion," he muttered.
The strange vibration returned again.
Soft.
Barely noticeable.
But it was there.
A faint hum beneath his skin.
Kael closed his hand slowly.
The feeling eased.
His eyes drifted toward the window again.
Toward the ridge.
Toward the place where the earth had swallowed him.
He exhaled slowly.
If the crystal had done something to him…
If that chamber really existed…
Then the answers were still down there.
And no one else even knew it was there.
Kael stood.
His ribs protested, but the pain was manageable now. Years of working in the mines had made him used to bruises and strains.
He crossed the room and opened a small wooden chest near the door.
Inside lay his work gear.
Tools.
Mining lamps.
Harness straps.
And a pair of worn fingerless leather gloves.
Kael picked them up and pulled them onto his hands.
The leather was cracked and darkened from years of stone dust and sweat. His hands were thick with calluses from hauling equipment and working drills since he was barely tall enough to lift them.
Even without elemental affinity, Kael had always kept up with the other miners through sheer stubborn effort.
Being Groundless had only meant he had to work harder.
He flexed his fingers.
The rune remained hidden beneath the leather.
Good.
Then he paused.
If something had been making those scraping noises in the tunnels…
Going down there unarmed would be stupid.
Kael knelt beside the chest again and dug through the tools until he found what he wanted.
A steel survey rod.
The rod was nearly a meter long, solid steel with a worn grip where years of use had polished the metal smooth. Miners used them to test unstable rock or probe loose ground before drilling.
Kael lifted it and spun it once in his hand.
The weight felt good.
Solid.
Reliable.
If anything down there decided to attack him, it would think twice about getting close.
He grabbed his mining lamp from the shelf beside the door and clipped it to his belt.
The beam flickered briefly when he switched it on.
Still working.
Kael hesitated for a moment.
If his mother caught him leaving tonight…
That conversation would not go well.
But the pull toward the cavern was growing stronger.
Not physical.
Something else.
Like a quiet voice in the back of his mind.
Come back.
Kael slipped outside.
The night air was cool against his skin.
He moved quietly along the edge of the house and down the slope toward the mining ridge.
The settlement lights faded behind him as he approached the sinkhole.
Most of the miners had gone home for the night.
Only a few lanterns remained near the excavation equipment.
Kael circled wide around the work area, keeping to the shadows.
When he reached the ridge, he crouched and looked down into the shaft.
Moonlight revealed the collapsed slabs wedged halfway down.
The same narrow gap he had been pulled through earlier.
Still unstable.
Still dangerous.
But now Kael knew something the others didn't.
There were tunnels down there.
And they connected to something ancient.
He secured a rope to one of the equipment anchors the miners had left behind.
Then he lowered himself slowly into the shaft.
Loose gravel shifted beneath his boots as he descended.
The air grew cooler the deeper he went.
When he reached the gap between the slabs, Kael hesitated.
This was where he had felt it earlier.
The vibration.
He turned sideways and squeezed carefully between the stones.
For a brief moment the sensation returned.
The same deep hum inside the rock.
Like distant thunder rolling through the mountain.
Kael froze.
The stone pressed around him felt alive with movement—tiny stresses and shifts deep within the earth.
It was the same feeling he had experienced earlier.
Like the mountain was speaking.
Then it vanished again.
"Okay," he whispered.
"That's definitely not normal."
He dropped the last few meters and landed lightly on the cavern floor.
Darkness swallowed him.
Kael switched on his lamp.
The beam cut across the massive cavern.
Everything looked the same.
The towering pillars.
The branching tunnels.
The distant silence.
But now he knew what lay deeper inside.
Kael pulled the steel rod from his belt and held it loosely in one hand.
"Just going to look," he said quietly.
"No crystals. No glowing explosions."
He stepped toward the tunnel leading back to the chamber.
The sound came almost immediately.
Scrape.
Kael froze.
Another noise followed.
A faint scurrying sound against stone somewhere deeper in the darkness.
Kael tightened his grip on the rod.
"Right," he murmured.
"Forgot about the locals."
The sound came again.
Closer this time.
Something was moving through the tunnels.
And it was heading toward him.
Kael swallowed.
"Well," he muttered.
"Guess we're doing this."
He raised the steel rod slightly and stepped cautiously into the tunnel.
The darkness ahead shifted.
And something down there was coming to meet him.
