The Iron Resolve’s mechanized carts rolled through the narrow tunnel, wheels skimming smoothly over the stone as the roar of a distant forge rumbled to life. A rising heat washed over the adventurers, sharp and dry like the breath of a great beast. Sparks and glowing embers floated through the air like deadly fireflies, the faint sound of metal being hammered resonating in the distance.

Jake gripped the wheel of his cart, eyes narrowing as they emerged into the cavernous expanse of the next room. The Molten Forge sprawled before them—massive, imposing, and alive with the heartbeat of fire.

The room was vast, a titanic forge dominating its center. An enormous metal anvil, blackened and cracked from centuries of use, sat beneath a spiraling column of lava cascading from the ceiling like a molten waterfall. The liquid fire pooled around the room’s edges into bubbling pits, casting a flickering orange-red glow across the stone walls. The track looped in a wide circle around the forge, weaving close to the lava at some points and arching over stone bridges at others.

Hanging above the track, suspended by heavy iron chains, were several treasure chests swaying gently in the heat. Beyond their reach for now, they seemed both enticing and foreboding—just another piece of this deadly puzzle.

Gouts of flame erupted intermittently from vents in the walls, shooting out across sections of the track. It was as if the forge itself breathed fire, alive and angry at their intrusion.

The carts rolled to a stop without warning as an ominous clang rang out, louder than any forge hammer, and echoed throughout the room. The ambient heat intensified, waves of shimmering air distorting the adventurers’ vision as a towering figure stepped into view from behind the massive anvil.

Vulcanis.

The Molten Forgemaster loomed over them, a mechanical juggernaut of smoke, steel, and fire. His broad, iron-plated chest was engraved with glowing orange runes that pulsed rhythmically, like a forge's bellows. His dual hammers, each as large as a man, glowed with molten fury, leaving faint trails of embers in the air as he swung them with casual ease.

His head tilted slightly, the arcane symbol on his metal brow blazing like a sigil of dominance. His molten eyes, burning like twin furnaces, regarded them with interest as his booming voice filled the cavern.

“Well, well…” Vulcanis said, his tone both heavy and mocking, a sound like steel grinding against stone. “What have we here? More little invaders come to test their strength?”

The adventurers sat frozen in their carts, weapons at the ready. Even the flickering flames around the room seemed to pause, as if listening to his words.

Vulcanis took a single step forward, the ground shuddering beneath him as molten slag dripped from his hammers. “I know you,” he rumbled, pointing a hammer toward the party. “You were there. You fought alongside the dungeon’s keepers when the beasts dared to invade.”

He let out a deep, mechanical chuckle, smoke billowing from the vents across his back. “Your steel was strong, your fire resilient. For that, you have my thanks.” He bowed his head slightly, the motion strangely formal for such a monstrous being.

Jake exchanged wary glances with Bell and Sarah, unsure whether this was genuine or merely part of the dungeon’s design.

“But do not mistake gratitude for mercy,” Vulcanis continued, his tone shifting to a harsher edge, like tempered steel. “I am Vulcanis, the Molten Forgemaster, protector of this forge and the workers who serve the Dungeon Core.” He raised his hammers high, fire coursing along their length as he continued. “And my duty remains unchanged.”

He planted his massive hammers into the stone floor with a deafening boom. “If you wish to leave this place, you will earn it. There is no escape without proving your mettle.”

As if triggered by his proclamation, the track beneath the adventurers rumbled to life. Sparks danced along its length as the mechanical carts jolted forward, engines humming in protest as if eager for the challenge ahead.

Vulcanis stepped back toward the anvil, his burning gaze never leaving them. “Run, fight, survive… or be forged into ash.”

The words lingered ominously in the air as Vulcanis raised both hammers and slammed them down onto the anvil. The resulting shockwave rippled outward, the forge erupting with renewed fury. Lava surged higher, flame vents spewed arcs of fire across the track, and the treasure chests hanging from the ceiling rattled ominously.

The carts lurched forward.

“By the gods…” Phil breathed, sweat beading on his elven brow. His fingers hovered nervously near the crossbow strapped to his back as his cart gained momentum.

“Did that… thing just thank us?” Bell grunted, his tone disbelieving as he gripped the steering wheel tightly. The heat was oppressive, even for the sturdy dwarf.

“Only to say he’s still going to try and kill us,” Sarah muttered, scanning the forge anxiously. “Classic dungeon logic.”

Carah squinted up at the hanging chests swaying above them. “Those are not there for decoration,” she said, an edge of excitement in her voice. “And I’ll bet whatever’s inside them will help us survive.”

“Great,” Jake said, steering his cart into line with the others as they approached the start of the forge’s first loop. “So now we’re fighting a metal giant in a fiery death room while trying to hit targets out of flying treasure chests? This dungeon hates us.”

Mitch, who had been whistling nervously to himself, let out a weak chuckle. “At least it’s a memorable way to go, right?”

“Not helping, Mitch,” Parker grunted, his eyes locked on the massive Vulcanis as they looped closer to his position. The forge master’s molten eyes followed their movements, his hulking form framed by the glow of lava pouring behind him.

The track curved upward slightly, bringing the carts closer to the treasure chests. The adventurers could now reach the tantalizing targets. The chests dangled low as the carts whizzed beneath them.

“Okay,” Jake called over the noise of the carts and the roar of the forge. “You see those chests? Grab what you can when we pass under them!”

Swinging up at the chests, Jake and Bell managed to hit their targets and they shattered under the force of their blows. Into their laps fell hand crossbows with a small quiver of bolts.

Bell grumbled, “Crossbows. Why does it always have to be crossbows?”

“Because you’re short and can’t reach anything else,” Carah shot back with a smirk.

As the carts picked up speed, Vulcanis’ deep laughter echoed through the cavern once more. With a sudden motion, he lifted one of his hammers and hurled a fireball across the room. It crashed into a section of the track, erupting in flames.

“WATCH OUT!” Sarah screamed as the carts swerved to avoid the blaze.

The adventurers had no time to breathe. The forge was alive with fire, Vulcanis was preparing another attack, and another set of treasure chests came into view.

Jake shouted, “Get ready! Aim for the targets—move, move!”

The carts raced forward, weaving through the forge’s oppressive heat, Vulcanis’ fireballs streaking dangerously close. The adventurers who hadn't hit any before reached for the treasure chests, bracing for the chaos to come.

And all the while, Vulcanis’ booming voice taunted them again:

“Let us see if your steel is strong enough to endure the fires of the forge!”

The roar of Vulcanis’ laughter echoed through the molten chamber, mingling with the grinding wheels of the mechanized carts.

“Let us see if your aim matches your courage!” Vulcanis bellowed, raising one of his glowing hammers high. A fireball erupted from its surface, arcing across the forge and crashing onto the track with an earth-shaking explosion.

Unauthorized tale usage: if you spot this story on Amazon, report the violation.

The adventurers barely swerved their carts in time to avoid the blaze, their faces glistening with sweat from the oppressive heat.

Jake and Bell each gripped their newly acquired hand crossbows tightly, the weapons lighter than they expected but sturdy in their design. Bell grumbled under his breath as he reloaded.

“Crossbows… these cursed things never shoot where I want ’em.”

“You’re doing fine,” Jake shouted back, keeping one hand on the wheel and the other ready on the crossbow. “We’ll need every shot we’ve got for this room!”

The others weren’t so lucky yet. Carah’s cart weaved under another hanging chest, her eyes narrowing as she reached up.

“Come on… come on!” she muttered, fingers just grazing the bottom.

With a wild lurch of her cart, she reached for the chest and struck the bottom with her dagger. The chest shattered, scattering splinters, and a sleek hand crossbow tumbled neatly into her lap.

“Got one!” Carah whooped, spinning the weapon experimentally.

Parker, the ranger, wasn’t far behind. His cart jostled sideways as he ducked under another chest. Using his hand axe to smash one to bits. A crossbow clattered onto his cart floor.

“I’ll take that,” he said smugly, grabbing the weapon.

Phil, the elven mage, scowled as his own attempts failed miserably. “Am I the only one not playing fetch with these things?”

Sarah, driving her cart just behind him, offered a dry laugh. “Maybe the dungeon doesn’t trust you with sharp objects.”

Phil’s response was cut short as Vulcanis unleashed another wave of fireballs, each one crashing perilously close to the adventurers as they rounded another bend in the track.

The track twisted sharply, hugging the curve of the lava-filled room. As they emerged around the anvil’s far side, one of the four massive anvils scattered throughout the chamber suddenly flared to life.

The anvil’s head glowed bright orange, a circular target sigil appearing and pulsing in rhythm with the forge’s heartbeat.

Jake’s eyes widened. “There! That’s the target!”

Carah, quick to realize, spun her crossbow into position. “We’re supposed to hit those!”

Without hesitation, she fired. The bolt streaked across the forge, striking the glowing center of the target with a satisfying crack. The target shattered in a burst of sparks, and the anvil’s glow extinguished.

Vulcanis froze mid-swing. For a single heartbeat, silence fell over the room.

And then Vulcanis’ booming voice reverberated with renewed fury. “You think you can defy my forge? Then face its wrath!”

He slammed both hammers onto the ground, sending shockwaves across the room. Segments of the track shook violently, molten sparks raining down like fiery hail. Flame vents hissed, their blasts of fire growing longer and more erratic.

“Uh, great. He’s mad now,” Mitch groaned as he ducked his head to avoid a spray of embers. “Way to go, Carah!”

The adventurers sprang into action, the race now a frantic loop of dodging fire, aiming, and surviving.

“Next target’s gotta be on another anvil!” Jake called out, his cart veering around a sharp curve. “Eyes open!”

Phil gritted his teeth, glaring at the treasure chests still hanging above them. “Forget the chests—we need to hit the targets!”

“You’re just mad you didn’t get a crossbow,” Parker shot back as he scanned the room. “There! Next anvil—right side!”

A second anvil ignited, its sigil pulsing ominously.

Jake steadied his cart as he lined up the shot. Steering with one hand, he aimed the crossbow with the other. “Come on… hold steady…”

He loosed the bolt. It struck home, the target exploding into sparks just as the first had.

Vulcanis roared again, hurling a massive fireball with terrifying accuracy. It splashed across the track, forcing Jake and Bell to swerve violently, their carts narrowly avoiding the flames.

Bell cursed under his breath. “He’s gettin’ faster with those damn hammers!”

The track’s loops grew tighter, the speed of the carts increasing as the heat intensified. Flames hissed, lava bubbled, and Vulcanis’ attacks became relentless. The forge felt alive—angry and chaotic, as if testing them at every turn.

Sarah wiped sweat from her brow, glancing up just in time to see the third anvil blaze to life near the far wall. “Next target! Far side!”

“Got it!” Parker shouted, loading his crossbow.

He turned in his seat, one hand on the wheel and the other raising the weapon. His shot rang true, striking the third target dead center. Sparks erupted, and the sigil vanished.

Vulcanis’ laughter turned into a furious growl. “You dare defy me again?! I will break you!”

With alarming speed, Vulcanis slammed a hammer into the ceiling, dislodging chunks of molten rock that rained down onto the track. Jake swerved hard to avoid a falling boulder, his cart skidding dangerously close to the edge of a lava pit.

“This is insane!” Mitch cried, his voice high-pitched as he dodged a flaming projectile. “What kind of blacksmith has a death trap for a workshop?!”

The adventurers’ carts rocketed around the final stretch of the track, their pace frantic as Vulcanis’ hammer strikes became deafening. The fourth and final anvil lit up near the center of the forge, its sigil pulsing like a beacon.

Carah shouted, “Last one! Finish it!”

Bell, who had been quiet up to this point, raised his crossbow, muttering under his breath. “Never liked these blasted things…”

He steadied his aim and fired. The bolt struck the center of the final target, shattering it in a burst of brilliant sparks.

The forge rumbled ominously as Vulcanis froze, his hammers falling to his sides. For a moment, all was still. The fire vents hissed one last time, then sputtered out.

The adventurers slowed their carts instinctively, hearts pounding.

Vulcanis raised his head slowly, his glowing molten eyes meeting theirs. Instead of anger, there was something else in his gaze—respect.

“You… have passed the trial,” he rumbled, his voice echoing with grudging approval. “The forge yields to those who prove their mettle. But mark my words…”

He pointed a hammer at them, embers swirling in its wake.

“The fires of the forge do not forgive the weak. The next round will not be so easy.”

With that, Vulcanis stepped back toward his massive anvil. The room’s temperature began to drop slightly, the lava retreating just enough to expose the path forward.

A massive stone door at the far end of the room groaned open, revealing the exit.

“Let’s get out of here before he changes his mind,” Jake muttered, pushing his cart forward.

As the adventurers exited Vulcanis’ molten forge, the oppressive heat finally began to dissipate, and the tunnel ahead offered a momentary reprieve.

“Let’s keep moving,” Jake said, his voice firm but wearied. “Something tells me it’s not getting any easier.”

Their carts rolled forward, the dim glow of flickering torchlight guiding them through the tunnel. Then the passage opened up, and the team skidded to a stop, jaws slackening as they took in the scene before them.

A distant clang sounded, and somewhere deep within the chamber, the low whir of unseen mechanisms began to hum.

Jake’s knuckles whitened on the wheel. “Oh, you’ve gotta be kidding me…”
