Chapter 18: Chapter 18: The Maw’s Heartbeat

The fog didn’t clear after the fight—it only thickened, as if the Shroud itself was drawing closer to see who dared disturb its silence. The air stank of black ichor and scorched metal. Every breath burned.

Bright leaned against a half-collapsed wall, his blade dripping with crawler blood. The tremor underfoot hadn’t stopped. If anything, the heartbeat had grown stronger—faster.

Ba-thump.

Ba-thump.

Ba-thump.

Duncan spat on the ground. “We can’t stay here. The next wave will find us.”

Link crouched near the corpses, cleaning his daggers. “Assuming there’s even a safe direction left.”

Adam stared down at the crawler carcasses, fingers twitching. “They’re converging. All of them. Toward one point. If we head back, we’ll run straight into the horde.”

Bright’s eyes flicked toward the dense fog to the east—the direction the sound came from. “Then we go forward.”

Duncan’s head snapped toward him. “Forward? Toward that thing? You’ve lost your mind, Bright.”

“Maybe,” Bright muttered. “But whatever’s making that sound—it’s not a nest. It’s a call. And if the Shroud wants us closer, it’s because we’re near something it doesn’t want us to find.”

The air pulsed again, making the loose stones around them tremble. Somewhere beyond the mist, something moved in response.

They began walking.

Every step deeper into the fog made the world twist a little more. The ruins around them didn’t stay still—walls bent at odd angles, broken windows reflected movement that wasn’t there, and the ground sometimes dipped even though it looked flat.

Link whispered, “The air’s thicker here.”

Adam nodded, voice low. “The fog isn’t natural gas—it’s particulate. Organic. The Shroud’s… breathing it out.”

Duncan scoffed, but his eyes never stopped scanning the shadows. “You’re saying the air’s alive?”

“I’m saying everything here is,” Adam replied quietly.

Bright’s Danger Sense pulsed faintly—too faint. Normally, it warned him like a whisper in the back of his skull, an itch of incoming danger. Now, it pulsed irregularly, flooding him with false alarms that made his muscles twitch for no reason.

He winced, gripping his temple. “It’s… noisy. I can’t tell what’s real.”

Duncan looked back at him. “Noisy?”

“It’s like the whole place is… vibrating in my head. Too many threats. Too many moving things.”

They all fell silent after that.

The deeper they went, the more they found evidence of others—crushed helmets, discarded blades, burned-out lanterns. They stumbled across a half-collapsed barricade manned by corpses in tattered uniforms.

Roegan’s insignia gleamed faintly on one of their armor plates.

Duncan knelt beside the body, eyes grim. “Iron Circle squad. Looks like they fought to hold this line.”

Bright crouched near a scorched patch of ground. “They were buying time.”

“For what?” Link asked.

“To retreat—or to lure something away.”

As if in answer, the fog around them trembled.

Then came the sound—slow, dragging, heavy footsteps echoing through the hollow city.

Everyone froze.

“Form up,” Duncan hissed.

They hid behind a wall of rubble, peering through the cracks. A shape emerged from the mist—a massive crawler, larger than the others, its body fused with fragments of armor and bone. It dragged a shattered spear in one claw, Roegan’s spear, and its chest glowed faintly with a red, rhythmic light.

The heartbeat.

Duncan’s breath caught. “That’s it… the source.”

“No,” Adam whispered, eyes wide. “That’s a carrier. The pulse isn’t its heartbeat—it’s resonating from something inside it.”

The crawler moved slowly, methodically, as though searching for something. With each step, the heartbeat grew louder—vibrating through the ground like thunder.

Bright gripped his blade, though his wrist still ached from before. His Danger Sense flared uncontrollably, screaming of death and suffocation and something deeper.

Link whispered, “We can’t fight that thing.”

But Bright didn’t answer. He watched the faint crimson light pulsing inside the crawler’s chest. Something about it drew him in—like it was calling to him.

The crawler stopped suddenly. Its head turned, eyes glowing faintly.

It was staring right at them.

“Move!” Duncan barked.

The creature roared, the sound splitting the air like shattering glass. It charged, smashing through the wall that hid them. Bright dove aside as debris exploded around them.

Link fired, bullets sparking uselessly off the monster’s plated skin.

Duncan met the charge head-on, spear glowing faintly with bone-guard energy. He struck at the crawler’s leg, forcing it to stagger but not fall. The creature retaliated with a sweep that sent Duncan flying into a pile of stone.

Bright lunged, blade slashing across the crawler’s arm. It barely flinched. The red glow from its chest intensified—heartbeat now roaring like war drums.

Ba-thump.

Ba-thump.

BA-THUMP.

The vibrations made Bright’s head spin. His Danger Sense became a chaotic blur of motion, no longer warning him—just screaming.

Adam grabbed the fallen bag of cores, shouting, “Its chest—aim for the chest! The resonance is unstable!”

Duncan, coughing blood, planted his spear into the ground. “Then make it open up!”

Link darted left, firing into its face. The crawler flinched, distracted, and Bright took the opening. He sprinted forward, one arm trembling, and jammed his blade into a seam in its armor. The creature shrieked, backhanding him away.

His body hit the ground hard—his ribs screamed—but he saw it then: cracks forming along the crawler’s chest, the red light spilling out like molten fire.

“Duncan—now!” Bright roared.

Duncan’s spear glowed bone-white as he slammed it into the creature’s chest. The sound that followed wasn’t a roar—it was a detonation of flesh and light.

The crawler convulsed and collapsed, the red glow flickering weakly before fading.

Silence followed.

The fog around them pulsed one last time, and then—for the first time since entering the Shroud—the heartbeat stopped.

Adam stumbled closer to the corpse. “The core…” he murmured. He reached into the creature’s shattered chest and withdrew a crystal unlike any they had seen before—dark red with streaks of black lightning running through it.

Link exhaled shakily. “We actually killed it.”

Duncan leaned on his spear, panting. “No,” he said quietly. “We survived it. There’s a difference.”

Bright stared at the core, the way it shimmered faintly even in the fog. “Whatever that is,” he said, “it’s not just another power. It’s a piece of the Shroud itself.”

Adam met his gaze, eyes reflecting the eerie glow. “Then maybe we just cut out its heart.”
