Chapter Seventeen: The First Siege

The first siege of the dungeon began before dawn.

They came in the hundreds. Men and women from the city’s broken edge, carrying torches made from pipes wrapped in cloth. Their boots clattered across the hollow streets, through fog and rubble, drawn by a scent that mocked the starving: smoke, fruit, and clean water.

They moved like a tide, their voices rough and desperate. Some sang old war songs to keep their fear at bay. Others muttered prayers to gods long buried under ash. Children clung to their parents, eyes wide, while raiders carried guns that hadn’t been cleaned in years. Every one of them had heard the same story: of meat that grew from vines, of rivers that ran sweet, and a paradise waiting below the ruin.

No one believed it was a dungeon.

The Sapling had felt them coming for hours. The tremor of their steps rolled through the soil like a growing heartbeat. It remembered fire, remembered the screaming of the dead, and it braced itself. The wolves stirred first. Thorn raised his massive head, fur prickling, eyes glinting pale green. The air grew heavy.

At the mouth of the labyrinth, the first group stopped.

They stood before a hole ringed by vines and glowing moss, the air beneath it faintly warm. The one in front, a man named Rook, leaned on a metal spear wrapped in tape. He had been a scavenger captain once, before his crew starved in the wastes. His face was a map of old cuts and sunburns. Behind him came thirty others, carrying packs, ropes, and a handful of guns that clicked when checked.

“Smell that?” said a woman behind him. “That’s food. I can smell it from here.”

Rook nodded slowly. “Stay close. We go in quiet. Take what we can carry. Don’t eat until we’re back out.”

They descended.

The air changed with every step: cooler, wetter, alive. The moss along the walls pulsed with slow light, breathing in rhythm with something deeper. Shadows rippled, not from their torches, but from movement in the walls themselves.

“Feels like it’s breathing,” muttered one of the younger men.

They passed into a cavern shaped like a ribcage. The path forked five ways. To the left, faint light glimmered. To the right, the sound of running water echoed softly. Rook motioned his people to spread out.

That was their first mistake.

The moment the first team entered the left tunnel, the floor gave way. A scream cut the air. Rocks shifted. Then silence. The others turned their lights toward the hole—only to see thick roots squirming in the dark below, wrapping around what remained. A spray of red hit the walls, then vanished as the moss drank it in.

“Pit trap,” Rook growled. “Watch your feet. Step where I step.”

This tale has been pilfered from Royal Road. If found on Amazon, kindly file a report.

They pressed on.

In the distance, they could hear others entering—the second and third groups—shouting orders, hammering metal, firing shots into the dark. Their lights flashed like fireflies through the maze.

The labyrinth had awakened.

A hiss came from ahead. A cloud of dust burst from a hole in the wall. One of the women screamed, clutching her face as stinging nettles erupted across her skin. Her torch fell, setting off a series of small, sharp pops as pods in the walls exploded and hurled shards of rock. A man stumbled, his throat torn open by a splintered fragment.

“Back!” Rook shouted, but the tunnel behind them had shifted. The way they’d come was now gone—closed by a curtain of vines thick as rope.

They were inside now.

The Sapling watched from its roots. It didn’t hate them. They were hungry, as all creatures were. But it had built the labyrinth for this: a defense, a lesson, a living reminder that paradise was not meant for the greedy.

Rook’s group turned right, following the sound of water. The air grew thick with mist. A cavern opened before them, lit by faint blue mushrooms. Pools of clear water gleamed on the ground.

“Water!” Someone yelled, breaking rank.

Before Rook could stop him, the man fell to his knees and scooped a handful to his mouth. He didn’t scream—his jaw simply melted away. Flesh sloughed off into the pool as if it were wax. The rest stumbled back in horror as the water began to bubble, releasing a sharp, acrid scent.

“Acid,” Rook rasped. “Don’t. Touch. Anything.”

They skirted the pools and moved deeper, passing under archways of stone veined with roots. Ahead, the tunnel split again—one wide, one narrow. The wide path seemed safer, smoother.

Rook chose the narrow one.

Behind them, the second group poured into the wide passage, their lights bobbing like stars. For a moment, Rook looked back and saw their silhouettes vanish in a flash of orange. A roar of fire followed. When the smoke cleared, the tunnel glowed red-hot, molten from within.

The dungeon was learning.

Hours passed, or days, it was hard to tell. The deeper they went, the more the walls pulsed with faint light. The sound of movement echoed through every corridor: claws scraping, wings beating, something heavy dragging across stone.

They stumbled into a forest underground.

Roots hung like curtains from the ceiling, brushing their faces. The air smelled of moss and fur. Rook raised his torch and froze. Eyes gleamed between the trees—dozens of them. Wolves.

“Don’t run,” he whispered. “Don’t—”

The first one leapt. It tore through a man’s throat before he could even aim. The others followed, silent and fast, ripping through the ranks like smoke through leaves. Gunfire lit the dark for only seconds before the wolves vanished again, leaving bodies twitching on the ground.

Rook fired blindly, backing away. His boots sank into something soft. He looked down and saw the ground itself breathing. The floor was not earth but a layer of thick roots, and they were moving.

“Run!”

They crashed through the undergrowth, wolves snapping at their heels. The trees thinned. The smell changed: sharp, chemical, wrong. Ahead, light flickered blue and white.

They had entered the thunder grove.

It was beautiful. Dozens of trees stood in a ring, their branches humming with power, crackling arcs dancing from trunk to trunk. Sparks leapt through the mist, hissing like serpents. At the center stood the electric tree—the heart of the grove—its trunk split by light.

The moment they stepped closer, the air screamed. Lightning struck the ground inches from Rook’s feet, turning stone to glass. Another flash hit the man beside him. He fell without a sound, smoke curling from his body.

“Back!” Rook shouted, but the wolves had driven them forward, and behind the wolves came something far larger.

Thorn stepped from the shadows.

The bear’s fur shimmered faintly, veins of green light running under its skin. Its eyes glowed like twin moons. It moved slowly, as though pitying them, then reared up and roared. The sound rolled through the grove, shaking the ground.

Rook raised his gun. The barrel quivered. The bear took one step—and lightning struck again, this time through Thorn, through the ground, through the men. The world went white.

When Rook’s vision returned, he was alone. Smoke and ash drifted around him. The trees hummed quietly, satisfied.

He staggered backward, half blind, and found the path behind him gone. The vines had sealed again, silent and patient.

He dropped his weapon. His knees hit the wet soil. For a moment he thought he saw shapes moving in the fog—people, perhaps the others—but they were only shadows, half-formed things the labyrinth had taken for itself.

In the distance, he could hear screams—other groups still fighting, still running through unseen traps and shifting corridors. But even those sounds began to fade, swallowed by the endless hum of the electric forest.

Rook crawled until he could no longer move. The moss beneath him pulsed faintly with warmth. He looked up, saw the faint glow of the ceiling roots, and smiled a broken smile.

“Paradise,” he whispered. “You really are alive.”

Then the ground opened beneath him, and the labyrinth took him too.

Above, the surface was silent again. The air smelled of rain and sap. The vines that sealed the entrance swayed softly in the wind.

Deep below, the Sapling listened. It felt the last of the intruders fade from its tunnels, their lives sinking into its roots like dew. There was no triumph in it, only quiet necessity.

The first siege was over.

The labyrinth had endured.
