Ludger let his senses press outward again, deeper this time, searching not just for bodies or mana clusters, but for patterns. Reactions. Threads. Anything linking the spread of moss to the structure around them.

He still found no clear monster presence close by. But the absence itself was starting to feel less like safety and more like stage-setting. He slowed slightly and lifted a hand. The group halted with him.

He crouched near the wall and studied one of the recently harvested sections more carefully. The fireball lowered a little, bathing the area in warmer light. The exposed stone beneath was scratched. The remaining moss around it looked harmless enough at a glance, but the texture varied too much. Some parts were lush and soft. Some were coarse. Some had tiny pale filaments running through them in web-like patterns so fine they almost disappeared unless the light hit just right.

Ludger did not touch it this time.

“Don’t brush against the walls unless you have to,” he said.

Rowan immediately shifted a half-step away from one side of the corridor.

Jennifer mirrored it. Eclaire had already been keeping distance. Luna adjusted her line without comment. Viola rolled one shoulder and muttered, “That instruction would have been more comforting before the explanation.”

“It still works now,” Ludger said.

Then he rose again and continued forward, slower than before.

The corridor seemed tighter all of a sudden, despite not changing shape. The moss no longer looked merely damp or medicinal. It looked present. Observant in its own passive, spreading way. Every patch of green clinging to the stone had become suspect. Every hanging strand now carried the possibility that it was not just growth, but interface. Not just a resource, but a sensory organ.

Behind them, the fireball’s glow trailed over the walls in flickering pulses.

Ahead, the passage bent deeper into the labyrinth. And with each step, the feeling of being watched did not fade. It sharpened. The deeper they went, the worse the feeling became.

It did not spike all at once. There was no obvious trigger, no sudden roar in the dark or flash of hostile mana to mark the change. It simply kept building step by step, corridor by corridor, until the pressure of being observed stopped feeling like a passing instinct and started feeling like a fact.

Something knew they were here. Something had known for a while. And if Luna and Eclaire had sensed it earlier, now the entire group could feel the shape of it pressing at the edges of their nerves.

The moss got thicker too.

At first it had merely covered the walls heavily. Now it was beginning to dominate them. Great layered mats of it spread over the stone in overlapping growths, dense enough in places that the original wall could barely be seen beneath. Some patches bulged outward like damp flesh. Others draped down in hanging green curtains that brushed the edges of the corridor. The color varied as they descended farther, dark green in some places, almost black in others, with streaks of pale jade and sickly yellow threading through the thicker sections.

The passage itself grew wetter. Not flooded. Not yet. But the air had changed.

It clung to the skin now, damp and cool enough that each breath felt heavier going in. The fireball Ludger kept floating ahead no longer just illuminated the corridor; it sent faint trails of steam from the warmer pockets where heat touched slick stone and soaked growth. The smell of wet earth, medicinal rot, and old trapped moisture thickened until it felt like the labyrinth was trying to crawl into their lungs.

Then they started noticing the droplets. A soft sound at first. Tick. Then another. Tick.

Water falling from the ceiling in scattered spots, hitting the floor, moss beds, or exposed stone with quiet little impacts that somehow made the silence around them worse instead of better. In some places the droplets were infrequent, little more than lingering seepage gathering in cracks before finally letting go. In others, they fell often enough to form dark wet patches on the ground or small threads of water sliding down the wall before vanishing into the moss.

Viola tilted her head slightly as another drop struck stone nearby. “That’s new.”

“It’s increasing,” Luna said.

Eclaire looked upward toward a cracked section of ceiling where moisture had gathered around the roots and moss growth. “There should be a pond nearby,” she said after a moment. “Or a stream. Maybe even an underground river.”

Ludger’s gaze moved over the walls, then the ceiling, then the heavier moss beds that seemed to drink half the corridor’s dampness and exhale the rest back into the air.

“Maybe it’s the humidity,” he said.

Viola looked at him. “The humidity?”

“The moss,” Ludger said. “This much growth traps moisture. If it’s feeding on both ambient mana and the water in the air, then the corridor itself could be staying saturated. Enough for water to gather in cracks and low points until it condenses and starts dripping.”

Luna glanced at a thick wall patch, expression faintly displeased. “So the walls are sweating.”

Stolen from Royal Road, this story should be reported if encountered on Amazon.

Ludger’s mask turned slightly toward her. “That’s one way to say it.”

“A disgusting way,” Viola muttered.

Ludger let the others talk while he focused harder.

His senses had already been working constantly since they entered, but now he pushed them deeper, more deliberately, ignoring the easy surface readings and pressing farther into the structure of the place itself. Mana Sense spread outward through the corridor and into the surrounding stone, separating what belonged to the growth from what belonged to the labyrinth.

He slowed. The fireball drifted ahead. Then he frowned. That got everyone’s attention immediately.

“What?” Jennifer asked.

Ludger’s eyes remained on the corridor ahead, but his focus was clearly elsewhere now, buried in the readings beneath and around them. “The mana is thick here.”

Eclaire folded her arms. “That much is obvious.”

“No,” he said. “I mean the composition.”

He touched the wall lightly with two fingers, more to orient himself than because he needed the contact.

“The earth mana is strong. That’s normal. It’s a labyrinth.” His voice stayed low and distorted through the mask. “The water mana is strong too. Stronger than it should be this close to the outer section.”

Luna’s brows drew together. “Because of the moss?”

“Maybe partly.”

He kept reading. The sensation was strange enough that it irritated him. The elemental patterns were not wrong exactly, but they refused to settle into a clean arrangement.

“They’re almost converging,” he said.

That drew a full pause from the others.

Jennifer frowned. “Earth and water?”

Ludger nodded once.

“Too close together. Too blended.”

Viola frowned at the walls like they had personally offended her. “That sounds weird.”

“It sounds abnormal,” Rowan said quietly.

That was the better word.

Earth and water were not enemies in the strict sense, but they were not naturally close partners either. Earth favored structure, density, support, resistance, mass. Water favored flow, adaptation, erosion, movement, saturation. They could coexist in terrain, obviously. Mud existed. Swamps existed. Underground rivers cutting through stone existed. But for their mana patterns to feel this tightly layered, this interwoven, without a clear natural source like a major body of water nearby…

That was wrong. Or engineered. Or mutated. Ludger’s eyes narrowed.

“Earth and water shouldn’t be this compatible,” he said. “Not in a place like this. Not unless something is forcing the interaction.”

“The moss?” Luna asked.

“Possibly.”

“The guardian?” Eclaire added.

“Also possible.”

Jennifer looked down the corridor, her expression growing tighter. “Could the labyrinth itself be doing it?”

Ludger did not answer right away. Because that possibility was the most annoying one.

Labyrinths were not just underground spaces full of monsters and resources. The deeper or stranger ones developed internal logic over time, warped by mana density, repeated harvesting, resident creatures, environmental adaptation, and whatever original purpose had shaped them. If this place had spent years, maybe longer, growing medicinal moss under heavy water and earth influence while hidden behind a noble barrier, then the whole structure might have begun changing into something that did not obey ordinary elemental expectations anymore.

Which meant assumptions would become less useful the farther in they went. Wonderful. A droplet struck the ground near his boot. Then another fell from a hanging patch of moss farther ahead. The sound felt louder now.

Ludger rose fully and looked down the corridor where the fireball’s light kept catching on wet stone and thick green growth, making the passage shimmer faintly in places. It would have almost looked beautiful, if beauty had not been entirely ruined by the fact that the walls might be sensing them and the mana composition was behaving unnaturally.

The group resumed moving after that, but even more carefully than before.

It had only taken them about half an hour of steady movement through the first stretch of corridor to reach it, and during that entire advance they had not run into a single true dead end. No maze loops. No sealed side passages meant to waste time. No false branches designed to split intruders apart. The first section had been almost offensively direct.

Which was useful. And also suspicious.

A sealed labyrinth tied to noble interests should not have let them move that cleanly unless either the outer route had been curated for repeated use… or the real difficulties began deeper in.

Ludger slowed at the threshold leading into the second section and let his senses sweep ahead again.

The corridor widened briefly before narrowing into a darker descent with rougher stonework and thicker mana saturation. The moss spread over the entrance frame itself, clinging to the carved stone edges in layered bands that looked more deliberate than natural growth had any right to be.

He clicked his tongue once behind the mask. Half an hour. Too slow.

Safe by normal standards, perhaps. Careful by infiltration standards, certainly. But not enough for what they were doing. Ludger opened his mouth, already preparing to say it.

They should split here. No, more accurately, they should stop pretending this was a group pace problem. He would advance faster alone, map the section, identify the threat, and come back if necessary. It was the obvious answer.

Before the words could leave him, Viola spoke.

“Don’t even think about it.”

Ludger turned his masked face slightly toward her.

Viola folded her arms and gave him the kind of stare that suggested she was already offended by the argument he had not yet made. “Whatever stupid variation of ‘I’ll go ahead alone because I’m faster’ you were about to say,” she continued, “save it.”

Luna, standing just behind her, said nothing, but the look in her eyes made it very clear she agreed.

Viola pointed a thumb toward the next section. “We can all go in running and face whatever is ahead together. That was the point of bringing a team, remember?”

Ludger stared at them for a moment. Not because he lacked a counterargument. He had several. All of them reasonable. Most of them irritatingly correct.

He was faster. Harder to pin down. More capable of surviving the kind of sudden escalation that killed other people.

All true. Which was exactly why they were already glaring at him like they expected him to say something troublesome. He sighed. The sound came out through the mask in that warped, hollow way that made resignation sound vaguely threatening.

“All right,” he said at last. “Keep up.”
