Chapter 20: The House of Rot and Relics

The Buntu estate did not rise from the jungle; it was slowly being consumed by it.

Rangga stood at the edge of the clearing, his boots sinking into a carpet of necrotic ferns that seemed to shy away from the house's foundation. It was a sprawling, colonial-era structure of dark, termite-riddled teak, strangled by thick, emerald vines that looked more like serpents than flora. A heavy, cloying scent of wet earth and ancient dust hung in the stagnant air, thick enough to taste.

"This is it?" Rangga asked, his voice barely a whisper. He felt the mountain’s heartbeat beneath his own ribs—a heavy, rhythmic thump-thump that synchronized perfectly with the swaying of the vines above the porch. "My family lived here?"

Arung didn't answer immediately. He was standing a few paces ahead, his eyes tracing the jagged lines of the roof, his expression unreadable. He looked like a man standing before a tomb he had helped build but refused to acknowledge. He adjusted his grip on the stolen surveyor’s tablet, his knuckles white.

"They didn't just live here, Rangga," Arung said, his voice clipped and cold. "They anchored here. There is a difference."

"What does that mean? 'Anchored'?"

Arung finally turned to look at him. His eyes were hard, the color of a bruised twilight. "It means they traded their longevity for the silence of this mountain. Look at the architecture. Do you see the symmetry?"

Rangga looked. The house was built on a series of stone stilts that weren't merely functional. They were etched with the same amber, web-like patterns that were currently burning beneath his own skin. "The sigils. They’re everywhere."

"They are circuits," Arung corrected, stepping onto the sagging porch. The wood groaned under his weight like a dying animal. "And this entire house is the motherboard. Come on. If the mercenaries followed our trail through the high pass, we have exactly forty minutes before they track our heat signatures to this location."

"You talk like we’re playing a game of chess, but we’re standing in the middle of a graveyard," Rangga snapped, his frustration boiling over. He followed Arung, the floorboards screaming in protest. "My grandfather, my mother—they died because of this place, didn't they? And you knew. You knew the whole time we were in Jakarta."

Arung pushed open the front door. It swung inward with a high-pitched, agonizing whine of rusted hinges. "I knew they were Buntu blood. I didn't know the mountain was going to choose you as its next lock. If I had, I would have burned this place to the ground before you could read the inheritance notice."

The interior was a cavern of decay. Skeletal furniture sat draped in tattered lace sheets, frozen in time. Sunlight filtered through gaps in the roof, illuminating swirling motes of dust that danced in the stagnant air. In the center of the foyer, the floorboards had been ripped away to reveal a massive, circular stone well—the source of the oily, pulsating light Rangga had felt since they crossed the threshold.

"The well," Rangga whispered, drawn to it by an invisible tether. His skin flared with a sudden, hot luminescence, the obsidian patterns on his forearms throbbing in time with the light from the depths.

"Don't touch the rim," Arung warned, slamming his hand onto Rangga’s shoulder. The contact sent a jolt of static through them both, a sharp, electric reminder of their forced merge. "That isn't water down there. It’s concentrated geopathic radiation. If you touch that stone while your blood is reacting to the pulse, you won't just be an anchor. You'll be a battery. They’ll drain you dry before you can blink."

Rangga jerked away, his chest heaving. "Then why bring us here? If this is a trap, why are we standing in the center of the trigger?"

Arung began shoving heavy bookshelves aside, revealing a hidden compartment built into the wall. "Because the answers to why your blood is doing this aren't in the logs the corporate teams are hunting. They’re in your grandfather’s journals. He didn't abandon you to hide you from the world, Rangga. He abandoned you to hide you from them."

"Who? The corporations? The mountain spirits?"

Arung pulled out a stack of leather-bound books, their covers brittle and peeling. He tossed them onto a dust-covered table. "The Buntu clan wasn't a family. It was a containment unit. Your grandfather discovered that the mountain wasn't just a geographical formation—it was a sentient, volatile entity that feeds on kinetic energy. Mining it, drilling it, even just walking on it with greed in your heart, forces it to lash out. The Buntu were the ones who kept it sedated."

Rangga walked over to the table, his fingers hovering over the yellowed pages. He picked up a photograph that had slipped from the top journal. It was a grainy, black-and-white image of an elderly man standing in front of the very same well, his hands pressed against the stone. The resemblance was haunting. It was a mirror of his own face, thirty years older, lined with the same weary burden he now felt in his own bones.

"He looks tired," Rangga said, his throat tightening. "He looks like he hasn't slept in decades."

"He hadn't," Arung said softly, his voice losing some of its razor-edged distance. "I worked with him, Rangga. Before the syndicates moved into the valley. I was his protection detail when he tried to seal the central vent. He died so the mountain wouldn't swallow the valley whole. He didn't run. He sacrificed himself."

Rangga dropped the photo. The realization hit him harder than any bullet. "You were there. You were there when he died."

"I was," Arung admitted, his gaze dropping to the floor. "And I failed to keep the seal intact. That’s why I was looking for a replacement. That’s why I found you in Jakarta. I thought if I could train a new bloodline, I could finish the work. I didn't expect the mountain to pull you in so violently. I didn't expect to care if you survived the process."

The silence that followed was suffocating. Outside, the wind whipped through the trees, carrying the distinct, grinding sound of heavy machinery. The mercenaries had arrived, and they were closer than Arung had anticipated.

"They're here," Rangga said, his heartbeat accelerating. The pulsing light from the well spiked, turning a violent, searing shade of violet.

Arung lunged for the door, bolting it shut with a heavy iron bar. "We have to lock this place down. If they get into the archives, they’ll have the coordinates to the secondary vents, and they’ll destabilize the entire region."

"Arung, wait," Rangga said, holding up his hands. The obsidian patterns were now crawling up his neck, tracing the lines of his jaw. The temperature in the room was rising rapidly; he could feel the wood beneath his feet softening, as if it were turning back into living forest. "The house... it’s not just a library. It’s a mechanism. Look at the well. It’s not just emitting light. It’s feeding."

Arung looked back, his eyes widening. The oily, black sludge in the well was bubbling, rising higher. A rhythmic, grinding sound echoed from deep within the earth—a sound like tectonic plates shifting against one another.

"The seal is failing because we're here," Arung realized, his face paling. "The mountain isn't just reacting to the drilling. It’s reacting to the bloodline being back in the estate. We’re the keys, Rangga. Both of us."

"Both of us?"

"The bloodline is the lock, but the handler is the restraint," Arung said, his voice urgent. He grabbed Rangga by the forearms, his grip vice-like. "We have to bind ourselves to the well. We have to finish what your grandfather started, right now, or this entire valley is going to sink."

"I don't know how to do that!" Rangga shouted as a loud thud shook the front door. Someone was trying to breach the house.

"I do," Arung replied, his expression shifting into a mask of grim determination. He looked past Rangga, toward the door, then back at the well. "But it’s going to cost us everything. We won't be walking out of here as the people we were when we walked in."

The door buckled. A flashbang detonated on the porch, shattering the glass windows and filling the room with blinding, white light. The mercenaries were throwing everything they had at the house.

"Arung, they're coming through the wall!" Rangga warned, seeing the teak boards begin to splinter under the pressure of an explosive charge.

Arung pulled a blade from his belt, slicing his own palm. He didn't hesitate. He grabbed Rangga’s hand and pressed their bleeding palms together. The sensation was immediate and agonizing—a white-hot surge of energy that felt like liquid lead pouring into their veins.

"Hold on!" Arung roared, forcing their joined hands down toward the shimmering, oily surface of the well.

"Are you insane?" Rangga screamed, the heat becoming unbearable. The obsidian scars on his skin were glowing with an intensity that burned the surrounding air.

"It’s not insanity, it’s a bargain!" Arung yelled back, his eyes locked onto Rangga’s. The room dissolved around them into a blur of spinning light and sound. The mercenaries were pouring through the splintering walls now, weapons raised, but they moved as if they were caught in slow motion.

The floor beneath them didn't just vibrate; it gave way entirely, the wood transforming into a swirl of black, hungry shadows. The well wasn't a hole in the ground anymore; it was a gateway to the heart of the mountain.

"They won't get the records," Arung whispered, his voice suddenly calm amidst the chaos of the collapsing house. "They won't get anything."

The house groaned as the foundations shifted. The mercenaries stopped, their weapons lowering in sudden, primal terror as the floorboards vanished into an abyss of absolute darkness.

"Arung!" Rangga cried out, his body feeling as though it were being stretched across miles of stone.

"Together, Rangga!" Arung’s voice was the last thing he heard before the world folded in on itself.

They plummeted into the well, and as they fell, the house above them didn't just collapse—it imploded, pulled into the throat of the earth, burying every secret, every journal, and every mercenary under a mountain of shifting, suffocating rock.

In the dark of the void, there was only the sound of two pulses beating as one, and the terrible, grinding silence of the mountain finally getting what it wanted.

They were no longer in the house. They weren't even sure if they were still on the surface of the world. They hung in a state of suspended agony, caught between the crushing weight of the earth above and the impossible, thrumming heat below.

Rangga blinked, but his eyes saw only light—not the flickering light of the sun or the harsh glare of a flashlight, but a deep, geological glow that seemed to emanate from the marrow of his own bones. Beside him, he could feel Arung, his presence a steady, burning anchor in the chaos.

"Arung?" Rangga gasped, his voice swallowed by the sound of rushing wind.

"Don't let go," Arung’s voice came, strained and hollow, as if he were miles away. "The mountain... it’s testing the seal. If you let go, we’re scattered, Rangga. We’ll be part of the bedrock."

Rangga felt his consciousness fracturing. Memories that weren't his—the Buntu family, the history of the seals, the blood sacrifices of a hundred years ago—flooded his mind like a tidal wave. He saw his grandfather’s face in the flash of a moment, a silent plea for forgiveness. He saw Arung, not as a handler, but as a boy who had once been just as lost, just as terrified, standing in this exact same dark, waiting for a savior who never came.

"I have you," Rangga whispered, though he wasn't sure if he was speaking aloud. He pulled Arung closer, the amber obsidian on his skin flaring one last time, shielding them both from the crushing pressure of the mountain’s awakening.

The floor beneath them slammed into solid ground. The impact knocked the breath from their lungs, and the darkness was suddenly replaced by a deafening silence.

They lay still, tangled together on the cold, damp stone of a cavern floor, their limbs trembling with the residual energy of the descent. The air here was thin, metallic, and tasted of ozone and ancient rain.

Rangga tried to sit up, but his muscles felt like they were made of lead. He looked at his arms. The obsidian scars were gone, leaving behind only thin, silver lines that pulsed with a faint, steady light. He looked over at Arung, who was lying motionless, his face buried in the dirt.

"Arung?" Rangga crawled toward him, his heart stuttering. "Arung, get up."

Arung didn't move. A trickle of blood ran from his ear, stark against the gray stone.

"No," Rangga hissed, his hand hovering over Arung’s chest. He could feel it—a slow, irregular rhythm, but a rhythm nonetheless. He slumped against Arung’s side, the adrenaline finally deserting him, leaving behind a hollow, aching exhaustion.

Above them, the earth roared—a low, distant rumble of shifting tectonic plates. The mountain was settling, the seal effectively re-established, but the cost was etched into the very walls of the cavern.

Rangga looked around. They were in a vast, subterranean chamber filled with pillars of raw, glowing mineral. It was a cathedral of stone, and they were the only living things inside.

He leaned his head against Arung’s shoulder, closing his eyes. The hum was gone. The mountain was finally quiet.

Suddenly, a sharp, rhythmic click-clack echoed through the chamber. It wasn't the sound of stone shifting. It was the sound of a boot hitting solid ground.

Rangga’s eyes snapped open. He turned his head, his body tense.

At the far edge of the light, standing at the base of the secondary industrial lift shaft they had ignored, was a figure. They were dressed in tactical gear, dusted with the pulverized wood and stone of the destroyed mansion. In their hand, they held a high-frequency jamming device, its red light blinking with a steady, taunting pulse.

It was Hendra. And he was smiling.

"I told you," Hendra’s voice boomed through the cavern, mocking and triumphant. "You can't hide from the mountain when you're the ones holding the door open."

Rangga stood up, his legs shaking, his hand instinctively reaching for the pocket where he kept his knife, but it was gone—lost in the collapse. He looked down at Arung, then back at Hendra.

"How are you here?" Rangga demanded, his voice cracking.

Hendra gestured to the lift shaft behind him, where several more mercenaries were beginning to descend, their gear heavy and professional. "We didn't need to break into the house, boy. We just needed to wait for the rats to jump into the hole. The Buntu bloodline is such a predictable thing."

Hendra stepped into the light, his pistol leveled directly at Rangga’s head. "Now, hand over the anchor. The mountain is open, and we have a lot of harvesting to do."

Rangga looked at the lift shaft, then at the unresponsive Arung, and finally at the monolith of stone that sat at the center of the cavern—the true heart of the Buntu legacy. He realized then that the trap hadn't been set by the mountain; it had been set by them, and he and Arung had walked right into it.

"Kill me," Rangga said, his voice dropping into a dangerous, low hum that vibrated the very air of the chamber. "And the seal breaks completely. You won't harvest a thing. You’ll just be buried with us."

Hendra’s smile faltered, but his finger tightened on the trigger. "Try me."

The sound of a cocking hammer echoed in the silence, and just as the first shot rang out, the monolith began to glow—not amber, but a blinding, pure, terrifying white.

Rangga didn't move. He didn't blink. He just watched the light grow, a silent question forming in his mind: If they survive this, who will be left to kill?
