Kael reached the work zones as the first groups were already forming, the low murmur of voices blending into the constant noise of Racines, a dull, familiar mixture of movement, fatigue and routine that never truly stopped, only shifting from one form to another as the day unfolded. He slowed slightly as he approached, recognizing a few faces, people he had seen often through the years.
A man stood apart from the rest, a slab of hardened bark pressed against his forearm as he marked assignments with quick, precise movements, his gestures efficient without ever appearing hurried. He was dressed in fine layered silks, fabrics far too clean and too well-kept to belong in Racines, their muted colors catching what little light filtered through the roots, and even here, in the damp and filth, they retained a quiet sheen that set him apart more than any badge of authority ever could.
The overseer.
He did not belong to Racines. Men like him came from Trunk, from the levels where trade flowed and wealth accumulated, where the air was said to be cleaner and the ground no longer swallowed every step. He worked under the direct authority of the Trunk administrators, those who managed the movement of goods, labor, and resources between the lower strata and the higher reaches of Ygdrasil, ensuring that everything taken from below was accounted for, measured, and redirected upward without loss.
Here, he was not one of them.
He was above them.
And everyone knew it.
His posture remained perfectly straight, and there was in the way he held himself a kind of effortless distance, not imposed but assumed. A thin mask covered the lower half of his face, crafted from pale treated wood and lined with cloth, a barrier against the air of Racines that he refused to breathe directly, and though it concealed his mouth, nothing softened the expression in his eyes, which moved over the workers with quiet, undisguised disgust. He did not need to raise his voice or look up to be obeyed; it was enough that he stood there, untouched by the mud, by the smell, by the lives that moved around him, a reminder to all that he did not belong to Racines—and never would.
"Conduits," he said without looking up.
Kael exhaled quietly and stepped forward with the others assigned to the same task, joining a group of six that formed without discussion, each of them already knowing what awaited them below.
Kael adjusted the strap of his tool, the rough leather digging slightly into his shoulder as he shifted its weight into a more comfortable position. The instrument itself was little more than a long, reinforced handle ending in a flattened, hooked edge, its surface darkened by repeated use, its metal worn dull where it had scraped against hardened residue for years. It had no elegance, no refinement, only function, built to break, pull, and clear whatever clogged the conduits below, and like most things in Racines, it had been repaired more times than it had ever been replaced.
"Could've been worse," he said in a whisper. "Waste pits."
A few quiet chuckles followed, short and without real humor.
"Name's Daren," A man behin Kael said after a moment. "You've done conduits before?"
He looked about Kael's age, maybe a year older at most, taller by a head and broader through the shoulders, the kind of build that should have suggested strength if it hadn't been worn down by years of labor and too little food. His frame was solid, but there was something uneven in the way he carried it, as though his body had grown faster than it had ever been properly sustained. His face bore the marks of that same life, skin rough and slightly hollow at the cheeks, lips often pressed tight without realizing it, and faint scars crossing his jaw and brow where the work had left its traces.
"Yeah."
"Good," Daren said, the corner of his mouth lifting slightly as his grip loosened on his tool. "Then you already know it's just mud, stink, and a good way to lose half your day for nothing."
Kael glanced at him.
"Sounds about right."
Daren let out a quiet breath that could almost pass for a laugh.
"Only thing you gotta watch for is not slipping and drowning face first in it. Wouldn't be the worst way to go, but still."
The woman rolled her eyes faintly.
"Yeah, real comforting."
"What?" Daren shrugged. "At least it'd be quick."
Kael held his gaze a second longer.
"Could be worse."
Daren nodded once.
"Always is."
They kept walking, the air growing heavier as they descended, the humidity thickening until it clung to the skin and settled in the lungs, making each breath feel denser than the last. The ground beneath their feet shifted gradually, from unstable mud to a darker, more compact surface where water had pooled and receded countless times, leaving behind layers of residue that never fully dried.
The entrance to the conduits appeared between two massive roots, reinforced with old wood and hardened resin, the structure uneven but holding. From the outside, it looked like a simple opening carved into the earth, but everyone knew what lay beneath it stretched far deeper a network of tunnels dug under the base of Ygdrasil, extending outward and inward in equal measure, first carved generations ago in search of anything the surface could no longer provide, minerals, dense stone, fragments of hardened sap said to carry traces of the Tree's deeper properties, but over time, as the upper strata claimed the most valuable veins for themselves, what remained below had been repurposed into something far less noble, a hidden infrastructure meant to carry away waste and runoff, leaving those in Racines to maintain passages that had long ceased to benefit them..
They stepped inside one after the other, and the light changed immediately, dimming into something flatter. The tunnels were narrow, just wide enough for two people to pass if they turned sideways, their surfaces slick with moisture and lined with faint veins of sap running beneath the packed earth, emitting a dull, uneven glow that pulsed weakly through the walls. It was not enough to truly illuminate the space, only to outline shapes and movement, leaving everything else swallowed in a half-darkness that never fully settled into night nor allowed anything to feel clear. These conduits ran beneath Racines like a second, hidden structure, carrying away everything the upper levels refused to see, waste, runoff, organic decay, the byproducts of a city that fed constantly and discarded just as much. Left unattended, they clogged quickly, thickening into dense, immobile masses that flooded the lower areas and rotted everything they touched, which was why people like them were sent down here every day, tools in hand, to break, drag, and clear what no one else would.
Kael adjusted his grip on the handle as they moved deeper, the air growing warmer and heavier with every step until it felt less like something he breathed and more like something that coated the inside of his lungs. The tunnel widened slightly before opening onto their assigned section, and the smell reached them before the sight did, thick and sour, a layered stench of rot, stagnant water, and decomposing waste that clung to the back of the throat and settled there.
The channel ran along the center of the passage, clogged with a dense accumulation of dark sludge that barely moved anymore, its surface broken only by slow, reluctant bubbles that rose and burst with soft, wet sounds. The sap veins embedded in the walls cast a faint, uneven glow over the scene, just enough to reveal the texture of it all: fibrous residue tangled with hardened deposits, fragments of bone and refuse caught in the mass, everything pressed together into something that no longer resembled the individual things it had once been.
Water dripped intermittently from the ceiling, falling into the channel with dull splashes that barely disturbed the thickness below, and the ground around it was slick, layered with a paste of mud and organic decay that shifted underfoot if you placed your weight wrong.
"Smells worse today," someone muttered.
"That's because it is," Daren replied. "Hasn't been cleared properly."
"You always say that."
"Because it's always true."
The conversation faded as they reached their section and spread out, each taking position along the clogged channel.
For a few hours after entering the lower tunnels, Kael forced himself into a steady rhythm and let the monotony of the work dull the unease that had settled in his chest. The conduits were always unpleasant, always heavy with rot and mineral dust, but today the air seemed thicker, harder to swallow, as though the earth itself had decided to press a little closer against their lungs. He adjusted his grip on the handle of his scraper and tried to focus on the task at hand, reminding himself that thinking too much down here only made the hours longer.
The tunnels beneath Ygdrasil extended outward like a second root system carved by human hands, a network dug generations ago when Racines had first learned that survival required more than faith. Mineral veins ran beneath the base of the tree, rare deposits hardened by centuries of pressure, and those veins were the only reason Tronc still tolerated the existence of the lower strata. The ore extracted from these depths traveled upward, refined and traded, feeding the wealth of merchants who had never once set foot in mud. Without the conduits, Racines would be nothing more than a liability.
It was an odd comfort to know that even the highest levels depended on filth.
Daren worked a few paces to Kael's left, his movements efficient despite the confined space. Up close, the damage to his face was more apparent; faint scarring marked his jaw and cheekbones, the kind left by splintered stone or poorly handled tools, and his skin bore the grey undertone of someone who had grown without enough food and too much labor. Still, there was strength in him, the kind forged rather than inherited.
"You ever think about how much they'd panic up in Tronc if this place collapsed?" Daren muttered, dragging his tool through a clogged channel with deliberate force. "All that fine silk and polished floors sinking straight into the mud."
Kael allowed himself the faintest smirk.
"They'd finally understand what we've been walking on our whole lives."
The woman behind them snorted softly. "Careful. If the overseer hears that, he'll have you reassigned to latrines for a month."
"Worth it," Daren replied. "I'd like to see him try digging for once."
For a brief moment, the shared irritation eased the weight in the air. It was always like this before exhaustion set in, small jokes, quiet rebellion disguised as humor.
The scraping of tools resumed, steady and repetitive. Water dripped somewhere deeper in the conduit, echoing softly along the walls where faint veins of sap pulsed beneath the soil, casting a dull, uneven glow that barely outlined their silhouettes. The light did not brighten the space so much as prevent it from becoming absolute darkness, and over time the eyes learned to rely on contrast rather than clarity.
Kael wiped sweat from his temple with the back of his wrist and shifted his footing carefully. The ground here was less stable than it appeared; centuries of runoff and excavation had hollowed certain pockets beneath the surface. One misstep could mean a collapsed section, and collapse meant burial.
He was about to resume scraping when he noticed the vibration.
It was subtle at first, so faint that he assumed it came from the repeated impact of their own tools. The metal in his hands hummed slightly, a tremor traveling along the handle into his palm, and for a second he thought it was simply the echo of Daren's heavier strikes against stone.
Then Daren stopped.
The humming did not.
They all paused instinctively, as if some unspoken instinct had aligned them. The dripping water continued. Their breathing filled the space. The vibration lingered beneath it all, low and irregular.
"Feel that?" the woman asked quietly.
Before anyone could answer, the sound followed.
It was not loud. Not at first.
A dragging noise, slow and uneven, coming from deeper within the upper conduit that ran above their heads. It resembled metal scraping stone, but there was something organic beneath it, a wet undertone that did not belong to tools or shifting soil.
Kael frowned, glancing upward.
The upper channel had been abandoned years ago after a minor collapse. It should have been empty except for runoff.
The sound came again, longer this time, accompanied by a faint crumble of packed earth. Small fragments fell from the ceiling, scattering across their shoulders and tools.
Daren forced a short laugh. "Great. Something finally decided to fall apart."
But he did not resume working.
None of them did.
The dragging moved closer, deliberate rather than chaotic, as if whatever produced it understood exactly how much force was needed not to give itself away too quickly.
The crack appeared gradually along the seam of the upper conduit, thin and jagged, widening under pressure from within. More earth crumbled down, followed by a brief silence that stretched too long to be natural.
Kael's pulse quickened.
He told himself it was a minor collapse. He told himself the tunnels shifted all the time.
Then something pressed against the opening from the inside.
Claws broke through first.
Long, segmented appendages forced their way through the fractured earth, their surfaces slick and dark, the hooked tips biting into the edge of the conduit with controlled precision.
The crack widened further as the claws pulled.
The head that followed did not resemble anything Kael had ever seen. It was not cleanly formed. It looked assembled from overlapping plates of hardened flesh, layered and misaligned, opening and closing slightly as though testing the air. Between the plates, thin tendrils writhed and recoiled, glistening in the dim sap-light.
For a heartbeat, no one moved.
Then the creature dropped.
It landed among them with a heavy, wet impact that sent sludge exploding outward in a dark spray, and for a heartbeat its mass remained compressed against the ground as though the earth itself had struggled to contain it. Then it began to unfold.
What had seemed like a single body separated in layers, plates of hardened flesh sliding over one another with a slow, grinding friction, exposing glimpses of raw tissue beneath that glistened in the dim sap-light. Its surface was neither scaled nor skinned but something in between, fibrous and ridged, as though bark and muscle had been forced into the same shape and never properly agreed on the result.
Limbs emerged gradually from beneath its bulk, not symmetrically but wherever there was space, jointed appendages forcing themselves outward with a series of sickening adjustments, each articulation bending too far, then snapping back into alignment. Some ended in elongated, serrated ridges that pulsed faintly, their edges wet and dark, while others were thick and segmented, lined with small, twitching barbs that scraped against the tunnel floor as it shifted its weight.
Where its head should have been, a crown of overlapping plates parted slowly, revealing a cavity lined with quivering tendrils that recoiled at the faint glow of the sap veins along the walls. There were no eyes at least none that resembled anything human, but beneath the plates small, pale nodules flexed and contracted, reacting to movement with unsettling precision.
A thin strand of viscous fluid stretched from its underside to the ground as it lifted itself fully upright, and when it moved, the sound was not a roar or a hiss but a wet, dragging friction, like flesh sliding over stone.
The first worker did not even have time to scream.
One limb struck across his torso with a force that lifted him off his feet and hurled him against the wall. The impact produced a dull, cracking sound that did not belong inside a living body. Before he could slide down, another appendage drove forward, piercing through him and pinning him in place, blood spreading across the packed earth in a dark bloom.
Kael felt his legs refuse to move. His hands began to tremble. The tool slipped from his grasp and struck the ground with a dull, useless sound that felt far too loud in the enclosed space. Heat surged into his face while cold crept down his spine at the same time.
Daren shoved him hard.
"Run!"
The paralysis shattered.
They surged toward the exit in chaotic desperation, boots slipping in sludge, shoulders colliding, tools abandoned where they fell. The creature did not make any noise; it moved with frightening efficiency, its limbs striking in swift, controlled arcs that severed flesh as easily as butter.
A man stumbled beside Kael, his foot caught in uneven ground, and before he could regain balance, a hooked appendage swept low and sliced through his calf. He collapsed with a scream that echoed violently through the tunnel, clawing at the mud as the creature descended upon him.
Kael did not look back.
He ran.
The vibration intensified behind them, traveling through the ground and into his bones, a reminder that the thing was faster than it appeared. A shadow fell across him briefly as one of its limbs struck the wall inches from his shoulder, carving through packed earth with effortless strength.
He slipped.
His foot plunged into a soft pocket of sludge, and he pitched forward, hands sinking into the foul mixture as the stench filled his lungs. Panic surged, sharp and suffocating.
The ground trembled again.
He felt the displacement of air behind him, the rush of something massive descending.
Daren grabbed the back of his tunic and yanked him upward with brutal force, nearly choking him.
"Move!"
Kael stumbled forward just as a serrated limb crashed down where his head had been moments earlier, gouging a trench in the earth deep enough to swallow his arm.
They ran together now, shoulder to shoulder, the exit a dim, distant shape ahead of them.
Behind them, another impact sounded, followed by a wet tearing noise and a scream cut short.
Kael's mind struggled to reconcile what was happening. Creatures like this were supposed to remain beyond the thorn barrier. That was the purpose of the wall. That was what the Church preached.
The dragging sound resumed behind them, closer than it had any right to be.
How had it gotten inside?
And if one had managed to reach Racines:
how many more were already beneath their feet?
