The Forbidden Sector – Northreach Underground Mine. 500 Meters Below the Castle.
The air at this depth was thin and arid, carrying a biting scent of oxidized metal that stung the nostrils. The small Sudrath party navigated a narrow corridor of an abandoned excavation site, a place that had been left to the shadows for over a century. Rusted and twisted minecart rails were their only guide through the impenetrable darkness.
They moved in a tight, disciplined formation. Sir Riven led the way as the vanguard, hoisting a massive shield and a torch whose flame flickered wildly against the underground drafts. In the center, Sir Rianor and Lady Rumina walked side by side—one clutching a ledger, the other holding a detection device. Duke Lucian and Lady Rhea brought up the rear, their eyes scanning the darkness for any sign of movement.
"I swear, this atmosphere takes me right back to those night bravery tests at Scout camp," Riven whispered, his voice echoing softly against the damp stone walls. "The only difference is, back then, we were just scared of some counselor in a cheap ghost costume. Here, we might actually bump into the real deal."
"Don't talk about ghosts in a place like this," Rumina protested, her grip tightening on the hem of Rianor's cloak. "I've already got the creeps."
"Focus," Lucian's gravelly voice cautioned from the back. "The Sudrath ancestral records state this mine wasn't closed because the ore ran dry. It was closed because the miners accidentally 'unveiled something' that cost them their sanity."
Rianor paused, lifting a small canary cage to eye level. He observed the bird intently.
"The canary is still breathing normally," Rianor murmured. "Oxygen levels are safe. No trapped methane or carbon monoxide. We can proceed."
"You brought that bird just as a gas indicator?" Rhea asked, a hint of amusement in her voice. "I thought you just wanted a travel companion."
"It's called science, Rhea. Pure science," Rianor replied as he resumed his stride.
They trekked for the next hour, plunging deeper into the earth's crust. The temperature plummeted. Suddenly, the narrow tunnel opened up into a cavern of staggering proportions. Every one of them froze.
The cavern walls weren't dark. Instead, the stone itself was... radiant. Electric blue veins of metal snaked across the rock surface like a gargantuan nervous system. The light pulsed in a slow, hypnotic rhythm, bathing the cavern in a mystical, ethereal glow.
"Woah..." Riven slowly lowered his shield. "It's beautiful."
Rumina let go of Rianor's cloak. As a craftsman, she felt a pull at her very soul. She approached the wall, reaching out to touch one of the glowing veins with her fingertips.
"It's cold," Rumina whispered. "But it feels like... a tiny electric hum."
"Mithril," Lucian breathed, his voice thick with reverence. "The metal of the gods. Harder than steel, lighter than a feather, and capable of conducting magic a hundred times better than gold."
Rianor immediately pulled out his ledger, his eyes sparkling as if he were staring at a literal mountain of gold. "A deposit of this size... it's insane. If we manage to excavate all of this, House Sudrath's wealth will surpass the annual budget of the entire kingdom."
"But look at that..." Rhea pointed toward the center of the cavern with the tip of her dagger. "Who built that?"
Amidst the forest of Mithril crystals stood a massive metallic gate. It bore no resemblance to the timber or wrought-iron gates typical of the medieval era. Its surface was made of seamless, polished metal with a sleek, futuristic geometric design. It looked more like a bunker door from a sci-fi film.
"That wasn't made by humans or Dwarves of this era," Rianor said, approaching with extreme caution. "The precision of that craftsmanship... it was made by a machine."
As their footsteps drew closer to the gate, the cavern floor suddenly shuddered.
ZIIIING...
The blue radiance on the walls instantly shifted to an ominous, threatening red. A heavy mechanical groan echoed from behind the gate's shadow, followed by the sound of grinding gears and the hiss of high-pressure steam. HISS...
Something rose from the darkness. It wasn't a dragon or any organic beast, but a massive suit of armor standing four meters tall. Its body was a fusion of black stone and Mithril. Its eyes ignited with a harsh crimson light. In its right hand, it gripped a spear with a chainsaw-like tip that began to rotate slowly.
THE SENTINEL – Mechanical Golem.
"Get back!" Lucian barked.
"DEFENSIVE SYSTEM ACTIVE," a stiff, distorted robotic voice boomed from within the Golem. The language was archaic, yet intelligible. "INTRUDERS DETECTED. EXTERMINATE."
The Golem lunged with speed that defied its massive frame. Its whirring spear aimed directly for Rianor.
"RIVEN!" Rianor shrieked in panic.
CLANG!
Riven leapt just in time, catching the lethal strike with his heavy shield. However, the Golem's power was overwhelming. Riven was shoved back five meters, his boots plowing through the cavern floor as dust billowed.
"Damn! This thing is heavy!" Riven roared through gritted teeth. "Father! Help!"
Duke Lucian surged forward, his greatsword already shrouded in sharp, blue Aura. "Down you go, you old tin can!"
Lucian unleashed a powerful horizontal slash toward the Golem's legs.
CLANG!
Lucian's blade ricocheted off. There wasn't so much as a scratch on the Sentinel's leg.
"What?!" Lucian gasped. "The plating is an Adamantite alloy!"
The Golem spun, batting Lucian away with its massive backhand. Lucian was sent flying, slamming hard into the cavern wall. THUD!
"Father!" Rhea cried out. She immediately blurred into motion, searching for an opening. Rhea danced along the Golem's frame with the agility of a dervish, stabbing her daggers into its neck, armpits, and knees.
Tink. Tink. Tink.
Every strike was futile. Her rapier even bent slightly against the sheer hardness of the Golem's material.
"Impenetrable!" Rhea shouted, leaping back. "This is like trying to destroy a tank with a dinner fork!"
The Golem redirected its spear toward Riven. The saw at the tip roared louder. WIRRRRR.
Rianor, taking cover behind a Mithril cluster, forced his mind to work at hyper-speed. This is mechanical. It's a robot. There has to be a power source or a core. He watched the Golem's attack patterns. Every time it executed a heavy strike, a small panel on its back opened slightly to vent steam.
Heat exhaust vents. And inside... a glow of bright blue light.
"Riven! Hold it for ten more seconds! Don't you dare die!" Rianor yelled.
"Easy for you to say!" Riven grunted. He tossed aside his mangled shield and gripped his axe with both hands. "Come on, you oversized washing machine!"
Riven engaged in a contest of raw power with the Golem. Muscle against hydraulics.
"Rhea!" Rianor called out again. "Its back! There's a heat vent! Pierce the blue glow the moment it attacks Riven!"
"Understood!" Rhea vanished into the shadows.
Riven let out a primal roar, bracing the saw-spear against the shaft of his axe. His knees buckled under the strain. "Hurry up! My bones are about to snap!"
The Golem hoisted its weapon high for a finishing blow. The panel on its back hissed open completely. Psssht.
Rhea plummeted from a stalactite above with lethal precision. She gripped a Mithril dagger she had just scavenged from the floor.
"Die!"
Rhea drove the dagger deep into the exhaust vent, piercing straight into the core of the machine.
CRACK!
Blue electrical sparks sprayed wildly. The Golem began to seize, its internal mechanisms let out a discordant, grinding screech.
"ERR... OR... SYS... TEM... FAIL... URE..."
Its red eyes flickered several times before going dark. The massive frame collapsed forward with a deafening crash that shook the cavern.
BOOM.
Dust billowed high. Riven fell to his seat, gasping for air, sweat pouring down his face. "Hah... hah... that was too close. I was almost a Riven-pancake."
Lucian walked over with a limp, clutching his bruised shoulder. "You all... did an incredible job."
Rumina, who had been hiding in terror, ran toward the Golem's carcass. "Rianor... look at this."
She pointed to the Golem's chest, which had burst open from the internal overload. Embedded there was a glowing blue cube-shaped crystal. Rianor retrieved it. It felt warm in his palm.
"This isn't just common magic," Rianor murmured. "This is technology. Magitech."
Rianor stared at the mysterious metallic gate behind the Golem. "This cavern isn't just a mine, Father. It's a facility. Perhaps a laboratory from a lost civilization that's been erased from history."
"And it seems we've just become the rightful owners of the key."
The Great Hall (Family Mode: ON). Midnight.
They sat in a circle around the massive wooden table. In the center lay a chunk of Mithril ore and the faintly glowing Golem Core.
"Alright," Rianor said, his face serious but his eyes dancing with ambition. "We are officially the most dangerous family on the continent."
"How so?" Roland asked, who had stayed behind to manage the soap distribution.
"Because we have the raw materials to create weapons that can pierce any armor," Rianor pointed at the Mithril. "And we have a pure energy source that can run machines without electricity or human mana," he pointed at the Core.
"If Rumina can study how this core works," Rianor continued, looking at his sister. "We can build our own Golems. Or even crazier... Magic-powered trains. Automatic streetlights. Even firearms."
Everyone fell silent, their imaginations running wild. From a family on the brink of bankruptcy, they now had the potential to become the Industrial Kings of this world.
"However," Lucian interjected with a warning tone. "For now, keep your mouths shut. Seal off the mine. No one enters but us. If Morvath finds out we have Magitech, he won't just send assassins. He'll send the entire royal army."
"Agreed," Riven said. "I'll put Garrick on guard at the entrance. He's crazy enough to not ask too many questions."
"Speaking of assassins..." Rhea played with her dagger deftly. "Their deadline is in four days. They want 'That Item.' They probably think we're hiding Mithril haphazardly."
Rianor smirked—a malicious expression that made Roland shiver. "They want Mithril? Fine. We'll give them the 'Mithril' they're looking for."
"What? You're just going to hand over our treasure?" Riven asked, confused.
"Of course not," Rianor replied calmly. "We'll give them a special 'gift.' A booby-trapped package. When they come for it... they'll regret the day they were born."
Rianor turned to Rumina. "Rumi, can you make a flashbang using magnesium powder?"
Rumina grinned wide. "I certainly can. Do you want them temporarily blinded, or blinded until the next century?"
"Give me something that leaves them blind, deaf, and traumatized all at once," Rianor answered firmly.
