Crossing the first island proved easier than anyone expected. Aside from a few scattered ambushes along the coral ridges, the sahuagin resistance had been weak, disorganized and frantic without their real number, nothing like the coordinated assault they’d seen on the bridge.

The Lionsguard and Ironhand Syndicate cut through the scattered stragglers in minutes, advancing across black sand and mana-lit coral until the jungle thinned and the sound of the surf returned.

Ten minutes after landfall, they broke through the last ridge, and the view ahead explained everything. The archipelago stretched as far as the eye could see.

Hundreds of islands dotted the horizon, their cliffs jutting from the sea like shards of obsidian. Some were small, barely enough space for a dozen men to stand, while others rose high into the mist, draped in jungle and glowing veins of coral-blue light. The farther out they went, the larger and darker the islands became, until the horizon blurred into a jagged wall of stone and mist.

Lucius stepped forward, his boots sinking slightly into the damp sand. “There,” he said, pointing to a larger island a few kilometers ahead. It stood out from the rest, taller, rougher, and faintly pulsing with mana. “That’s our next objective. The path to the labyrinth starts there.”

Ludger and Gaius exchanged a look. They didn’t need to say anything.

Both touched the ground. The grains glowed faintly as mana pulsed through them, and the sea began to rumble. With synchronized movements, they pressed their palms forward.

The ocean floor obeyed.

Massive slabs of stone and coral rose from the depths, locking together piece by piece until they formed a wide, uneven pathway that stretched toward the next island. Each section solidified with a low, thunderous crack, sending plumes of mist spiraling upward.

By the time they finished, a bridge wide enough for three squads to march abreast connected the two shores.

“Path’s ready,” Gaius said, wiping his hands.

“Move out,” Lucius ordered.

The inland teams surged forward once again, the Lionsguard in front, Ironhand units following close behind with their mages in the middle ranks. The moment the first boots touched the new bridge, the sea below stirred.

A ripple spread across the water, then another, and within seconds, sahuagins began to surface. They came in waves, dozens at a time, leaping from the depths like spearfish. The water around the stone bridge churned with movement as they climbed and lunged with their tridents gleaming.

“Contact! Both flanks!” one of the scouts shouted.

Rathen didn’t even flinch. “Ironhand mages—handle it.”

At once, a line of robed casters stepped forward from the center ranks. Their hands moved in near-perfect unison, each forming complex sigils that flared in the air above them.

“Fire formation—volley!” their leader shouted. A heartbeat later, the sky erupted.

Flaming spheres and lightning arcs rained down from above, slamming into the sea with explosive force. The first barrage vaporized the front ranks of sahuagins instantly, scattering the survivors in a panic. Another volley followed, lighting up the ocean in brilliant orange and blue flashes that turned the air into steam.

Ludger watched from the front line as the mages pressed the attack, the air crackling with mana discharge. “Not bad,” he muttered. 

Lucius smirked. “Told you Ironhand members weren’t all muscle.”

The barrage continued, coordinated, efficient, ruthless. Every time the sahuagins tried to breach the bridge, they were met with walls of fire and shattering stone spells that hurled them back into the sea.

The fleet in the distance added its own voice to the battle. Magic cannons thundered again, targeting clusters that tried to regroup farther out, the concussive blasts sending fountains of seawater high into the air.

“Keep moving!” Lucius called out. “Don’t stop until we hit the next island!”

Ludger led the vanguard across the stone path, the bridge vibrating under the constant bombardment. Spray and fire mixed around them, mist and heat painting the world in motion. Viola stayed close behind him, eyes sharp, blade gleaming as she struck down the few sahuagins that made it through the mages’ barrage.

Ahead, the next island loomed closer, larger, darker, its cliffs streaked with glowing coral veins. Behind them, the sea boiled with the remains of the enemy.  Above them, smoke curled into the clouds.

The second island was different the moment they set foot on it.

The air felt heavier here, thick with mana and humidity. The trees weren’t quite trees at all, but twisted coral trunks and moss-covered stone growths, their roots merging with the black sand like veins crawling up from the ground. The canopy was dense, turning the sunlight into shifting streaks of gold and green.

The moment Ludger’s boots touched the soil, he knew. The faint tremor of presences there, but distinct. He closed his eyes and let Seismic Sense spread outward like ripples through still water.

At once, the island came alive in his mind’s eye. The vibrations painted a map beneath the surface: the pulse of the waves, the steady rhythm of marching troops behind him… and something else.

Still shapes. Too still. Dozens of them. Hidden in the coral thickets just ahead.

He opened his eyes. “They’re here.”

Beside him, Gaius had done the same, his expression grim. “Same readings on my end. Thirty, maybe more. Staying low, waiting for us to advance.”

Ludger straightened, brushing dust from his gloves. “Figures. The smart ones always wait for someone else to walk in first.”

Arslan, standing at the front of the Lionsguard column, turned at his tone. “What did you find?”

“The troublesome ones,” Ludger said flatly, nodding toward the tree line. “They’re hiding behind that coral ridge. Waiting to ambush when we push forward.”

Arslan cracked his neck, rolling his shoulders. “Good. Saves us the trouble of chasing them down later.”

Viola frowned. “So what’s the plan?”

Arslan drew his sword with a clean shing, the steel gleaming in the filtered light. “Simple. We handle it.” He turned to Ludger and Gaius. “You two save your mana. You’ll need it when the real fight starts.”

Ludger raised an eyebrow. “You sure?”

“Very sure,” Arslan said with a grin that was half confidence, half battle-hunger. “If we can’t handle an ambush, then we won’t accomplish anything.”

That earned a low chuckle from Gaius. “I almost feel sorry for the monsters.”

Arslan gestured for the formation to split, their two squads flanking wide, one holding center. The Ironhand mercenaries adjusted instantly, shields raised, bows drawn. Viola shifted beside her father, mana gathering faintly at the edge of her sword.

“Hold position,” Arslan commanded quietly. “Wait for them to show themselves.”

Ludger stayed back, arms folded, watching the area. The vibrations in the ground sharpened, he could feel the sahuagins tightening their muscles, preparing to spring.

The moment came a heartbeat later. The jungle erupted.

Sahuagins burst from the coral cover with shrieks that cut through the humid air, tridents raised, claws flashing. But before they could even close the distance, arrows and spells tore through them. Ironhand mages unleashed volleys of compressed flame and force; Lionsguard followed them with their speed and power..

Arslan met the first wave head-on, blade flashing as his Overdrive ignited. Each swing was a storm, cleaving through flesh and coral trident alike. Beside him, Viola darted through the gaps, her strikes heavy and precise, sending the sahuagins that tried to block her flying.

Kharnek and Freyra grinned from ear to ear as they used their axes to cleave through the armed sahuagins as well. Harold, Selene, Aleia, and Cor covered for them as well, trying to keep up and making sure that those morons wouldn’t trip and hit their heads in the coral.

Ludger watched it unfold with that faint, analytical calm that never left him. The tremors under his feet began to fade as the presences dwindled, one by one, until the island’s pulse settled again.

When the last sahuagin hit the ground, he nodded. “Clear.”

Gaius crossed his arms. “Not bad. Didn’t even need us.”

Arslan wiped his sword clean on the nearest corpse and smirked. “Told you.”

Ludger gave a faint shrug. “Guess I’ll save the big tricks for later.”

“Good,” Arslan said, gesturing for the troops to regroup. “Because something tells me this island wasn’t meant to slow us down, it’s meant to wear us out.”

Ludger glanced toward the dense interior of the island, where the coral trees grew darker and the mana in the air felt heavier. “Yeah,” he muttered. “And whoever’s running this show… they’re watching how fast we burn through our mana.”

Gaius nodded grimly. “Then we won’t give them the satisfaction.”

The group advanced again, tighter now, quieter—but sharper than before. The second island was no longer just terrain. It was a warning.

The second island proved more stubborn than the first. The terrain was uneven and treacherous, riddled with coral ridges, sinkholes, and jagged stone that crumbled underfoot. Every few steps, the ground shifted from damp sand to hard basalt, then to slick coral plates that gleamed faintly in the half-light. More than once, the soldiers had to slow their march just to find footing.

It wasn’t dangerous, just slow, frustratingly so. By the time they reached the far side, even Ludger’s patience was thinning. He glanced back toward the path they had carved across two islands now, temporary bridges of stone and coral, improvised routes that would eventually crumble to the tide.

“We’ll need to build a proper road here,” he said, brushing the grit from his hands. “Something that lasts beyond this expedition. A real connection to the bridge. Probably on the sea”

Gaius grunted his agreement. “If the Empire wants to keep this place, they’ll need more than boats and hope.”

Lucius came up beside them, cloak snapping in the wind. His eyes followed the coastline ahead, then lifted to the horizon. “There,” he said, pointing.

The third island, the one housing the labyrinth, rose from the sea like a continent in miniature.

It dwarfed everything they had crossed so far. Massive cliffs of black stone ringed its perimeter, streaked with luminous coral veins that pulsed like arteries, glowing faintly blue against the gray sky. From the center of the island, mountains jutted upward in fractured spires, their peaks lost in a shroud of mist.

And somewhere within that mist—hidden from view, was the entrance they sought.

Even from this distance, Ludger could feel the pull of mana emanating from it. A slow, rhythmic pulse that throbbed in the ground beneath his boots, steady as a heartbeat. 

Lucius’s expression hardened. “That’s it. The labyrinth’s island.”

They began preparing for the next bridge. Ludger reached to the ground and  Gaius did the same, both focusing in tandem to raise the next span of stone.

That’s when they heard it. A distant thoom, deep and resonant, like thunder rolling underwater. Then another.

Ludger froze mid-spell, head turning toward the sound. “Cannon fire?”

The next second, the sky to the south lit up with streaks of flame.

“Those are our ships,” Lucius said, eyes narrowing. “They’re firing at something.”

But from where they stood, they couldn’t see the fleet directly, the islands obscured the view, only flashes of light visible between the cliffs. The muffled echoes of explosions rolled through the air, vibrating faintly through the ground beneath their feet.

Then, over the horizon, they saw the cannonballs—massive glowing arcs of mana-charged projectiles, soaring high before crashing into the distant ocean. The detonations sent columns of spray dozens of meters high.

Something was wrong. The pattern wasn’t coordinated fire—it was panic fire. The next explosion confirmed it.

One of the cannonballs never reached the sea. Instead, it struck something, something moving. A massive wall of black shadow rising from the depths, its surface slick and scaled, large enough to blot out the light for a moment before the ocean swallowed it again.

And then came the counterstrike. The water surged violently, a wave like a mountain rising where the shadow had vanished. Then, impact.

A shape, too fast, too large, slammed into one of the warships near the rear of the formation. The explosion of water and splintered wood that followed was deafening even from kilometers away.

The ship cracked, a sickening sound that carried over the wind. Its hull split open like a wound, smoke and steam billowing as the crews scrambled to stabilize it.

“By the gods…” Viola whispered.

The water around the damaged ship churned violently, and for a moment they saw it clearly, a colossal shadow, serpentine in shape but wrong in every way. Multiple fins broke the surface, not aligned like a single creature’s but staggered, twisting. For an instant, Ludger thought he saw an eye, a vast, faintly glowing orb beneath the waves, reflecting the light of the burning ship.

Then it was gone again, sliding beneath the sea, leaving only the wreckage and the chaos of cannon fire. Lucius’s voice snapped through the silence. “That’s not a sahuagin beast… that’s something else.”

Ludger clenched his jaw. “It’s the same thing we saw under the bridge last time. The shadow that never surfaced.”

“Whatever it is,” Gaius said grimly, “it’s awake now.”

They could still hear the cannons in the distance, firing in desperate rhythm. The sound of their warships, their lifeline, being battered by something older and larger than any of them wanted to imagine.

Lucius’s grip tightened on his saber. “We need to move. If that thing breaches again, we’ll lose half the fleet.”

Ludger glanced toward the glowing cliffs of the labyrinth’s island, then back at the smoke on the horizon. The wind carried the scent of salt and fire between the two.

“Then we better finish what we came for,” he said. “Fast.”

And as the next tremor rippled through the ground beneath them, he realized something terrifying,  the pulse of mana coming from the labyrinth below was synchronizing with the rhythm of the sea beast’s movements. It wasn’t just a monster.
