The tunnels breathed.
It wasn't air or wind—just the slow, inaudible pulse of pressure, as if the whole world exhaled once every few minutes. Each beat set the crystalline walls quivering, faint waves of light rippling through them like veins under translucent skin.
They had been walking for what felt like hours. Time was impossible to measure down here; watches ran erratically, compasses spun uselessly, and even the Resonant Compass glowed only when it chose to. The deeper they went, the less the world above seemed to exist.
Seren walked ahead, her lantern cutting narrow gold arcs across the passage. Aron followed, muttering about signal loss and magnetic anomalies. Taren trailed a few steps behind, eyes half unfocused, listening.
The silence wasn't empty anymore—it carried texture, flavor, a weight that pressed against his mind. Somewhere beneath it, faint murmurs coiled like dreams spoken in another room.
When they reached a widening in the passage, Seren halted. "We camp here," she said. "Before the air turns thinner."
They set their gear down among the glass ridges. The floor was warm underfoot, as if the desert's sun had seeped all the way down. Aron crouched by the wall, tapping gently with a metal probe. The sound was clear, bell-like.
"This stuff isn't natural," he said. "The frequency response is too uniform. It's grown, not formed."
Taren knelt beside him, running his hand along the glass. It was perfectly smooth, yet it thrummed faintly under his fingers—a slow vibration that seemed to match his pulse. "It's listening to us," he whispered.
Aron laughed uneasily. "If it is, I hope it likes lullabies."
But then the vibration changed. The frequency shifted upward, turning the surface translucent. Beneath the glass, shadowy shapes stirred—indistinct outlines, faces maybe, half-frozen mid-expression.
Seren drew her weapon. "What did you do?"
"Nothing," Taren said. "It's responding on its own."
The faces solidified, then dissolved again, leaving only faint smears of light. For a long moment, no one breathed.
Aron finally broke the silence. "Okay, I officially hate this place."
Taren didn't answer. His reflection in the glass had begun to move again—but this time, not quite like him. The mirrored Taren turned its head a heartbeat late, then smiled faintly, a motion he hadn't made.
He stumbled back. "Did you see that?"
Seren looked up sharply. "What?"
"The reflection. It—" He stopped. The glass was blank again, only his own pale face staring back.
Seren stepped closer, scanning the wall. "Nothing now. Maybe the light—"
"It wasn't light." He rubbed his hands together. They were trembling. "It spoke."
Aron frowned. "You're hearing things again."
"No. It said my name."
The silence seemed to deepen, almost waiting for confirmation. Seren's voice was quiet but firm. "We don't say names down here. Not unless we have to. Understood?"
Taren nodded mutely.
They ate in uneasy quiet. The food packs tasted metallic, as if the air had tainted them. The lantern's glow flickered along the walls, painting long wavering shadows.
After they finished, Seren told Aron to take first watch. She lay back against her pack, eyes half open. Within minutes, her breathing slowed.
Taren stayed awake, sitting near the wall. The glass pulsed faintly, and this time the whispers were clearer—not words, but rhythms, patterns. He reached out with his mind the way the Guild had taught him to listen to the Pattern: without demand, without judgment.
And slowly, the murmurs aligned.
He could almost make out words. A woman's voice, low and distant.
Don't follow the hum. Follow the hollow.
He stiffened. "Who are you?" he whispered aloud.
The answer came like a sigh. You know me.
The face returned, faintly visible now—a woman's silhouette, features indistinct, but the shape of her eyes, the curve of her mouth—familiar. Too familiar.
"Mother?"
The image smiled sadly. You shouldn't have come here.
Taren's heart pounded. "Why? What is this place?"
A memory that remembers itself.
The light flickered; the image began to dissolve. Desperate, Taren pressed his hand to the wall. "Wait!"
The glass turned black. For an instant, he saw something vast reflected behind the fading face—an expanse of darkness threaded with veins of light, moving like breath.
Then the image vanished, and the whisper was gone.
He staggered backward, gasping. Aron jerked awake. "What happened?"
Taren shook his head. "Nothing. I just—dreamed."
But he didn't sleep again.
When Seren woke a few hours later, she found him still sitting there, staring at the glass. "You look worse than before," she said.
"Maybe I am," he murmured.
She studied him a moment, then softened. "Drink some water. We move soon."
As they broke camp, Aron ran another scan along the wall. "Getting strange readings," he muttered. "There's resonance in the structure—low frequency, like it's… singing?"
Taren froze. "You hear it too?"
"I don't hear it. The instruments do. But yeah, there's harmonic fluctuation through the entire tunnel system. Like it's alive."
Seren tightened her gloves. "Then we keep moving until it stops being alive."
They descended deeper. The tunnels grew narrower, the walls smoother. The whispers returned, fainter but omnipresent, like a thousand people murmuring just beyond comprehension.
Eventually, they reached a chamber that opened into a vast hollow dome. Light filtered down through cracks in the ceiling, diffused into soft blue haze. In the center stood a pillar of translucent stone, rising from the floor like a frozen fountain.
Aron approached it cautiously. "Looks like a data core. If I can tap its vibration—"
"Don't," Taren said sharply.
Aron hesitated. "Why not?"
"It's not dead."
Seren frowned. "Explain."
"The glass up there—it showed me faces. My mother's. It said this place is memory. If that's true, then everything we touch down here is alive with what used to be."
Aron rolled his eyes. "You're turning superstition into science."
Before Taren could reply, the pillar began to glow.
At first, it was faint—a shimmer running through the crystal like breath fogging glass. Then came the vibration, deep and steady, rising into a hum that filled the dome.
The sand on the floor began to move, swirling in patterns around their feet.
"Taren," Seren warned.
He stepped closer, unable to resist. The hum resolved into a voice—multiple voices, layered and echoing.
We were the listeners. We became the listened.
The words vibrated through his bones.
Seren raised her rifle. "Back away!"
Taren ignored her. "What do you want?" he asked.
We want you to remember.
Light flared from the pillar, engulfing them in white radiance. In that light, Taren saw fragments—images that weren't his but felt carved into his soul: the old Guild towers shining over oceans of mist, Anaya's hand tracing maps of living light, crowds standing in shared silence as the world first learned to listen. Then—darkness, confusion, collapse.
The voices grew mournful. They wanted harmony. They found obedience. They silenced themselves.
Taren fell to his knees. "What are you saying?"
Silence is mercy, the voices whispered again, echoing the words from before. But mercy becomes forgetting.
The light dimmed. The pillar's hum faded into stillness.
For a long moment, no one spoke. Only the faint echo of Taren's ragged breathing filled the dome.
Seren approached slowly. "Whatever that was, we're leaving."
Taren nodded numbly, though his eyes still glowed faintly from the reflected light.
As they made their way back through the tunnels, Aron whispered, "It said 'we.' Who's 'we'?"
Taren didn't answer.
At the final bend before the surface tunnel, he glanced back one last time. The pillar was dark again—but something new marked its surface. His name, faintly etched into the crystal, as if written from inside.
The desert above awaited, endless and shimmering. But when he looked up through the fractured ceiling, he realized the light wasn't coming from the sun.
It was coming from the sand itself—millions of grains glowing faintly, whispering together.
And beneath their feet, the ground whispered his name once more.
