The next morning broke clear and bright, the sky washed in pale gold as the tide rolled calmly against the shore. The storm from the day before had passed, leaving the sea deceptively peaceful,  the kind of silence that made people forget how quickly it could turn violent.

Before the sun had fully risen, Gaius and Varik were already flying on an earth platform back to the continent..

Ludger stood nearby, watching as they flew away. Gaius gave him a nod, calm as ever, while Varik stood beside him in his polished armor, already thinking of the logistics of contacting the Senate and securing Imperial resources.

This was their next phase: Gaius would coordinate with the mainland engineers to expand from the other end. Varik, meanwhile, would push for Senate funding, the heavy equipment, spell engines, and military reinforcements needed for a full-scale expedition.

They were heading back to the continent to prepare for war, just not the kind fought with swords. When they finally disappeared over the waves, Ludger turned back toward the worksite. The sound of hammering, shoveling, and geomancy echoed across the beach as dozens of workers, mages, and Lionsguard recruits moved under the rising sun.

His task for the day wasn’t simple. The bridge they’d started months ago still stretched for dozens of kilometers over the southern sea, but there were vast gaps remaining, places where the foundation had to be rebuilt from scratch. So Ludger worked on this side of the archipelago, raising new coral pillars to extend the bridge toward the islands.

He pressed both palms against the sand, feeling the pulse of mana through the earth beneath the waves. The ocean’s floor shifted under his control, stone and coral twisting together, forming massive cylindrical supports that pushed upward until they breached the surface. The sunlight caught their slick surfaces, painting the coral in hues of rose, gold, and pale blue.

Each pillar was massive, ten meters thick and dozens tall,  built to resist both the waves and the weight of future reinforcements. It was exhausting, delicate work; every formation had to be balanced against the others to prevent collapse. But Ludger moved with practiced ease, shaping the seafloor as if it were an extension of his own body.

Behind him, Arslan, Kharnek, Viola, Freyra, Lucius and Rathen stood watch. All of their heavy hitters were here today, the best fighters the expedition had left. The labyrinth team had been reduced to a skeleton guard posted near the entrance, but the main strength of their forces was focused on this beach.

They weren’t taking any chances. If the giant sea monster decided to strike again, it would find the Lionsguard, Ironhand Syndicate, and even the Northerners ready and waiting for it.

The mages patrolled the shoreline, keeping barrier wards active over the water, while archers stationed themselves atop half-finished coral pillars. Every few minutes, one of them would scan the ocean with mana-sense, searching for even the faintest disturbance.

Ludger stood waist-deep in the surf, sweat running down his temple despite the cool morning wind. He lowered his hands, focusing his mana into the final structure.

“Stoneflow,” he murmured.

The seafloor responded, coral and rock twisting together in a smooth spiral until it locked into place. The ocean around him rippled from the surge of released mana.

Arslan called out from the shore, “That’s the fifth in one hour. You trying to rebuild the entire bridge by yourself?”

Ludger didn’t look back. “If it keeps things stable, maybe.”

He wasn’t joking. Because until the others returned from the continent, the safety of this place,  the bridge, the islands, and everyone left behind,  depended on them holding the line here. And Ludger wasn’t planning to let anything rise from the depths again without being ready to crush it back down.

Another pillar rose from the depths with a low, grinding roar, sending sprays of seawater across the workers on the shore. Ludger stayed perfectly still, both hands pressed to the wet sand, eyes half-closed as he channeled mana deep into the earth beneath the waves.

His mana spread outward like ripples through the sea floor, dozens of kilometers wide, mapping every tremor, every pressure shift, every hint of life moving in the dark below. Seismic Sense.

The world unfolded in his mind as shapes and vibrations — fish schools fluttering like soft static, the distant groan of tectonic plates, even the rhythmic swells of the tide brushing against coral. He filtered it all, focusing on that one familiar pattern,  the colossal, rhythmic pulse he remembered from before.

But there was nothing. He opened his eyes slowly, exhaling a faint breath through his nose.

From behind him, Arslan called out, “Well? Anything down there?”

Ludger shook his head. “No. Nothing that size. The whole area’s dead quiet.”

Cor, standing a few meters away with his staff resting in the sand, lowered his hand from a blue sigil still glowing in front of him. “Same here. Mana Pulse came back empty.”

That made everyone pause. The sea was calm, almost too calm,  and the silence stretching across it didn’t feel natural.

“Could it have left?” Freyra asked, one hand shading her eyes as she scanned the horizon. “A creature that massive doesn’t just disappear.”

“It doesn’t make sense,” Viola said, her brows furrowed as she leaned on her sword. “That thing attacked the warships, wrecked five of them, and then… nothing? No sign of it since?”

Ludger didn’t answer immediately. His gaze stayed locked on the water, on the faint ripples that spread from the newest coral pillar. “Creatures like that don’t usually leave their territory without reason,” he murmured. “If it’s gone quiet, it’s either moved deeper… or it’s waiting.”

Lucius, who had been standing beside Rathen watching the reinforced the pillars, finally turned toward them. “Or,” he said slowly, “it might never have been working with the sahuagins in the first place.”

That drew everyone’s attention. He continued, “Think about it. You all said before that the creature appeared under the bridge long before the expedition started, when the sahuagins ever showed up in force.”

Ludger and Cor exchanged a brief glance, then nodded. “That’s true,” Ludger said. “It surfaced beneath us while we were still laying the pillars. Just watched us for a while… then sank back down. Didn’t attack. Didn’t even come close during the fight.”

Lucius spread his hands. “Exactly. Then maybe it wasn’t an ally at all. Maybe the sahuagins and that thing just crossed paths, and we got caught in the middle.”

Viola frowned. “You’re saying it just… got in their way?”

“Or they got in its,” Lucius replied. “If the labyrinth’s mana overflow is affecting the sea, it might’ve drawn that creature here by accident. Creatures that size are sensitive to mana fluctuations. The bridge, the pillars, even geomancy, all of it could have stirred it up.”

For a moment, no one spoke. The ocean stretched out before them, gleaming like polished glass under the afternoon sun, calm, silent, hiding its secrets well.

Finally, Arslan grunted. “Whether it’s friend or foe doesn’t change a thing. If it shows up again, we kill it.”

Ludger smirked faintly. “Agreed.”

He pressed his hand to the sand once more, sending another pulse through the seabed. Still nothing. Only that same quiet void below.

“Let’s hope it really did just swim off,” he muttered. “But I’ll keep checking.”

Because if that thing wasn’t gone, if it was just waiting beneath the still surface,  Ludger wanted to be the first to know.

Getting rid of the giant sea monster would make everything easier.

Ludger knew it the moment he heard Lucius and Arslan discussing logistics behind him. how much faster the bridge construction would progress, how the trade routes could finally open safely once the threat beneath the waves was gone. No more shattered hulls, no more sleepless nights wondering if the ocean would rise up and devour another ship.

It all sounded good. Too good. If the sea was safe, more people would come. Merchants, explorers, opportunists. And with them would come attention, especially from the Empire.

Ludger stood near the edge of the scaffolding above the surf, staring out at the glimmering horizon while the coral pillars rose in steady intervals behind him. His reflection wavered in the water, distorted by the gentle ripples of the tide.

“Once that beast’s gone,” he murmured, “they’ll pour in like vultures.”

And the Empire never missed a chance to tighten its hold. He could already picture it, Imperial inspectors, Senate delegates, “advisors” from the capital arriving under the pretext of aiding the project. Within a few months, the bridge wouldn’t just be a symbol of frontier unity. It’d be Imperial property, with banners and soldiers stationed on every pillar.

Lucius would probably resist, of course, he wasn’t the type to let bureaucrats take control. But even Lucius couldn’t fight the tide of politics forever.

Ludger’s gaze drifted back toward the mainland where Varik had departed that morning with Gaius.

The Imperial commander’s calm, collected demeanor came to mind, every conversation precise, deliberate, and frustratingly polite. In all the time they’d worked together, Ludger could count on one hand the times Varik had slipped emotionally. Even in the chaos of battle, when the sahuagins had attacked from below and the golems from ahead, Varik’s expression had barely changed. And that was the problem.

He couldn’t recall any moment where Varik had truly seemed off-balance. No subtle hesitation, no flicker of deceit, no misstep that gave away an ulterior motive. He’d acted exactly as a loyal Imperial officer should, competent, methodical, and cautious about information. Almost too cautious.

Ludger frowned slightly. “Either he’s one hell of an actor…”

The wind blew against his green scarf, tugging faintly at the fabric as he narrowed his eyes at the waves below.

“…or he really believes what he’s doing.”

It wasn’t impossible. Varik might genuinely be loyal to the Empire, doing what he believed was right,  not for money or ambition, but to keep the balance of power intact. Making sure no guild, no noble house, no frontier militia grew powerful enough to challenge the capital’s authority.

That kind of loyalty made him dangerous. Because if Varik was just another schemer, Ludger could predict him. Manipulate him. Break him if needed. But a man who believed wholeheartedly in order,  that kind of man wouldn’t hesitate to burn half the continent if he thought it kept the peace.

Ludger sighed and looked back toward the bridge under construction, the coral pillars gleaming pale in the sunlight.

For now, there was no proof, only instinct. Still, he’d keep an eye on Varik when he returned.

The labyrinth below was one kind of danger, but the kind that wore armor and smiled in meetings? That was worse.

In the end, a full month passed.

The days blurred together, long hours of construction, shifting tides, and the dull rhythm of chisels and magic echoing across the sea. The bridge stretched farther now, a chain of pale coral and stone pillars rising from the ocean, all the pillars had been finished. The work crews had grown more confident, their pace steady and uninterrupted. And through it all, there hadn’t been a single sign of the giant sea monster.

Not a ripple. Not a shadow beneath the waves. No vibration on Ludger’s Seismic Sense, no flicker on Cor’s Mana Pulse. The ocean had remained perfectly, eerily calm, as if nothing had ever lurked beneath it at all.

It should have been a relief. The crews laughed more, the guards relaxed their stances, and even Lucius began speaking of supply chains and completion dates instead of contingency plans. It was as if the monster had simply been a nightmare that faded with the morning light.

But Ludger didn’t believe in that kind of luck. He stood at the far edge of the latest completed section, boots planted on freshly shaped coral, eyes fixed on the water below. The sea glistened like polished glass, endless and deceptively still. It reflected the sky perfectly — a mirror so clean it looked fake.

And yet, he couldn’t shake it. Those eyes.

The memory flashed clear as the day it happened, when he and Gaius first saw the creature rise beneath the unfinished bridge. The water had glowed faintly around it, mana currents swirling in slow, deliberate motion. It hadn’t attacked. It hadn’t even looked angry. It had just watched.

Two colossal, unblinking eyes staring up through the depths,  intelligent, ancient, almost curious.

Ludger clenched his jaw. Even now, he could still feel that presence brushing against his mind, that cold, alien awareness. He’d faced monsters, men, and labyrinth horrors, but nothing had unsettled him like that one look.

He tried to tell himself that it was gone. That the ocean was just quiet now, that they’d imagined the weight of that gaze. But deep down, he knew better. Things that massive didn’t just vanish. They waited. They watched.

And no matter how peaceful the waves looked, Ludger couldn’t forget those eyes — not their size, not their color, not the strange sense that it had understood him in that brief moment.

Even if he tried, that memory wasn’t something time could wash away.

It wasn’t fear that lingered. It was certainty.

That thing was still out there, somewhere beneath the endless blue —

and sooner or later, it would look up again.
