The mine wasn't groaning.
It was breathing.
Kael opened his eyes in the dark, his heart already pounding. He hadn't heard anything—there had been no footsteps, no wind. Just that subtle shift in pressure, like someone had exhaled behind his eyes.
Across the sanctum, the others were still asleep, but the Codex beside him was awake.
Its surface shimmered beneath the low glow of the coals. Not glowing, not pulsing—shifting, like scales adjusting to a new temperature.
Something was stirring beneath them.
Kael reached out slowly, resting his palm on the cover.
It felt warm.
Too warm.
Renn stirred next, half-asleep and already grumbling. "Why do I feel like something decided we're tonight's special?"
Kael nodded toward the Codex. "It felt the tremor too."
Renn sat up. "Tremor?"
Kael hesitated. "I don't know if that's what it was."
"You're telling me we've got haunted stone now?"
"No," Kael said, then corrected himself. "Maybe."
By the time Brenn and Mira awoke, the air in the sanctum felt heavier, like the stone itself was pressing closer.
"It's colder," Brenn said, cracking his neck. "Colder than it should be."
Kael stared at the wall. "The resonance changed."
"Resonance?" Mira asked.
He nodded. "The mine has a rhythm. Most places do—magical feedback in the stone. This one just shifted."
"You mean the mine's alive?" Renn asked, only half-joking.
Kael didn't laugh.
Instead, he said: "Something beneath it is."
They geared up quickly.
Kael carried the Codex. Renn shouldered his trap pack. Mira wrapped her arm again to hide the glowing glyph on her skin. Brenn moved in silence, but Kael noticed he didn't stray far from Mira.
They returned to the shaft by mid-morning.
And the moment they reached the lip—
One of Renn's traps pulsed.
Faint. Subtle. Like a whisper in still air.
Renn knelt, pressing his palm to the glyph's edge.
His face tightened.
"It's moving. Fast."
"What is?" Brenn asked.
Renn didn't look up.
"It."
Kael dropped to a crouch beside him. "Describe it."
Renn's voice was calm, but there was a tremor in it. "It's not walking. It's not flying. It's… crawling. But not like anything I've felt. It's skimming the walls. In and out of crevices like water."
Mira stepped forward. "One of the Vault creatures?"
"No," Kael said quietly. "Worse. This one's… new."
"New?" Renn repeated. "As in freshly born? Out of what, glyph dust and bad ideas?"
Kael stood slowly, eyes locked on the shaft. "I don't know."
They descended together, cautiously.
The traps deeper in hadn't gone off—yet. The second layer remained stable. Renn was tense, marking every junction they passed.
When they reached the bottom, the silence hit them like a wall.
Kael's boots touched stone, and instantly he felt it—the glyphs were watching.
Not active.
But aware.
The pillar in the center of the cavern still stood untouched, but its surface was different now. Some of the glyphs had faded.
Others had moved.
Kael stepped closer, slowly. "They're rearranging."
"Glyphs can do that?" Mira whispered.
"Not unless they've been—"
He froze.
She caught it. "Unless they've been learned."
The first trap triggered with a sharp crack.
Renn jumped. "That was Trap 2."
They all turned.
Kael cast Veilcut—☿↯⟆⟹—and blinked as his vision sharpened.
He saw it.
Just for a second.
A shape, low to the ground. Crawling like a centipede made of glass. Its body shimmered with lines that pretended to be glyphs. Symbols slashed and stitched into unnatural patterns.
It wasn't alive the way a beast is alive.
It was animated thought.
"It's mimicking our glyphs," Kael said.
Mira stepped back. "How is that even possible?"
"It's not supposed to be."
Brenn stepped forward, hammer raised. "Then let's kill what's not supposed to exist."
"No," Kael said quickly. "Not yet."
"Why not?"
Kael glanced at the pillar. "Because it's learning. If we fight it now, it'll survive better next time."
"You're assuming it won't kill us first."
"I'm hoping my math is better than it instinct."
Renn snorted. "Good to know we're betting on logic against crawling glyph-things from the forbidden deep."
Another trap went off—closer, this time.
The creature had adapted to the first wave.
"It's reading me," Renn said. "It knows I'm the trap maker."
Mira stepped toward the stone wall, eyes distant. Her hand brushed the surface.
And she began to hum.
It wasn't the lullaby she usually sang.
This was lower. Sharper.
Like a war song buried in silence.
The moment her voice left her throat, the glyph on her wrist ignited -♬⧬⟡☾ – Elaria's Aria—but it changed color.
Not violet now. Not silver.
Crimson.
Glyphs along the cavern wall shimmered, flickered, then answered.
Kael turned to her. "What are you doing?"
Mira didn't stop humming. "I don't think I'm unlocking anything…"She hesitated, then glanced at the wall. "It feels more like I'm helping it remember."
Suddenly, more glyphs flared across the walls. Old. Unreadable. But connected. Like veins beneath skin.
Kael stared.
"They're not glyphs from the Codex."
"No," Mira said. "They're older."
And then they heard it—
A voice.
Not words. A sound carried through the glyph lines like breath through pipework.
Kael turned to Renn. "It's not alone."
Another trap exploded.
This one didn't trigger silence.
It triggered with a scream.
The creature reeled back, wounded.
Kael saw it writhe, its glyphs flickering.
And then—it spoke.
Not with language.
With repetition.
Kael's own voice echoed from its body:
"I don't know what it is.""I don't know what it is.""I don't know…"
Kael took a step back.
"It's learning from us," he whispered.
Brenn raised his hammer again. "Then let's teach it pain."
Kael lifted his hand.
Eidon's Vein flared—🜂⟁☉Ϟ⟴
He forced memory into the glyph, feeding it the burn of fear, the heat of watching his village die.
The glyph pulsed—
And the creature screeched.
Its body twisted violently.
Kael staggered as something inside it broke.
Then—silence.
It vanished into the dark.
Escaped.
But not before taking something with it.
Kael felt it go.
A sliver of thought. Torn from him.
Back at the sanctum, Kael sat alone beside the Codex.
It opened without touch.
A new glyph flickered into place beside Mindbrand:
⧬⟁⟡⚝ — Echobind
Not a weapon.
Not a shield.
A glyph that tied Kael's thought to others. For better or worse.
Beneath it, a phrase:
"You have been heard.What listens may now answer."
Kael closed the Codex slowly.
Because something had heard him…
And it was speaking back.
