Chapter 1: Strange Noises in the Abandoned Subway Ruins

Los Angeles rainy season always carried a smell of rust. Carl Brooks stood on the underground construction site of Subway Line Four, the brow beneath his hard hat knotted into a dead tangle. Rain seeped through the collar of his work jacket, ice-cold to the bone, but he had no time to think about the cold. He stared at the broken reinforced-concrete pillar before him, fingers dragging across the rough surface, tips smeared with a slurry of mortar and moisture.

"Mr. Brooks, the foreman says you need to have the borehole back in operation within half an hour." Project manager Jack Morris walked over, a crumpled set of blueprints tucked under his arm, his leather shoes leaving deep, dark prints in the mud. The roar of the site's excavators swallowed his voice, forcing him to raise it. "The timeline up top is squeezing us. Raymon Carter's gallery opening is next week. If this line slips any further, the penalty in the contract could buy three buildings."

Carl didn't look up. He simply reached into the tool pouch at his chest and fished out a pair of thick-rimmed glasses, sliding them on. Beyond the lenses, his eyes locked onto the core exposed at the pillar's fracture face. That space should have been dense bedrock and standard precast concrete, but what he saw instead was layer after layer of grayish-white, porous foreign material. They were embedded in the concrete like stones forcibly shoved into the mold.

"This isn't granite, and it isn't limestone." Carl's voice was soft, yet it cut cleanly through the noise. "This is bone."

Jack blinked, then let out a bark of laughter that ricocheted off the vast, empty underground space, shrill and ugly. "Bro, you're pulling my leg, right? This is Los Angeles, not some Indiana burial mound. That's just impurities in the cement. You get it?"

"Impurities don't form porous tubular structures." Carl pointed to a yellowed patch at the center of the fracture face. Rain was dripping steadily from that spot. "And these 'impurities' aren't distributed evenly. They're concentrated in the pillar's load-bearing core. If we drill along the original plan, the bit will shatter at the third stratum. Worse, the stress distribution here has been altered by these foreign objects. Support capacity is down by at least forty percent. If we don't reinforce, the moment the bore is through, the soil above will liquefy and settle."

The smile on Jack's face froze, but he didn't back down. Instead, his tone took on an air of condescending charity. "You're a railway engineer, not a geologist, and certainly not a forensic pathologist. Your hunch could be wrong. I have three geological surveys on file saying everything here is normal. Take my advice: sign the paper, go home, have a cup of tea. Don't make me lose face in front of Mr. Carter. The man is particular about these things."

Carl pushed his glasses off and wiped the fog from the lenses with the hem of his jacket. He looked at Jack, his gaze as still and flat as a dead pond. "You can walk. But the work stops. I need at least two hours to recalculate the support-bracket angles. Otherwise, when it caves in, everyone gets buried. Including those expensive paintings."

Jack stared at him for five seconds, then rolled the blueprints up and hurled them into the muddy water. "Two hours, Brooks. In two hours I want that drill bit turning again. Or I'll dock every cent of your consulting fee, pull your name off the blacklist, and tell the Los Angeles Times that the engineers at the Federal Rail Bureau are all in on a conspiracy."

Jack's footsteps faded into the distance. Carl stood where he was, rain pooling and streaming off his shoulders. He looked down at the fracture face again. The pale fragments lodged in the concrete threw off a dull, murky glow under the work lights. His professional intuition hummed like a taut wire, buzzing a warning: something had been buried in the wrong place.

Deep into the night, the site was lit only by the sickly amber haze of emergency lamps. Carl hadn't left. Flashlight in hand, he slipped past the sealed-off sections into the deeper, unsealed stretch of the construction zone. The air here was thick and sticky, heavy with the stink of stale earth mixed with the sharp, mineral tang of fresh concrete.

He crouched beside the broken pillar and flicked on his phone's flashlight. The beam swept across the white fragments. They had a diseased, milky-white color, their surfaces webbed with fine cracks. Carl leaned in close and inhaled. A faint trace of formalin, mingled with dust, crept up into his nostrils.

"This can't be right," he muttered to himself. "The concrete was poured fifty years ago. Unless … these bones were mixed in before the pour."

At that moment, a sharp, grating sound sliced through the silence.

Click.

Metal scraping against metal. Low, brief, and carrying a kind of tenacity that was distinctly, unsettlingly biological.

Carl whipped his flashlight toward the source. In the deep dark, an exposed rock wall yawned open. In it was an abnormal concavity, as though some enormous claw had gouged outward from the inside.

Click. Click.

The sound grew clearer. Rhythmic. Like something digging in a hurry.

Karl held his breath and slowly backed away. His heartbeat amplified against his eardrums, as though it might shatter his ribcage. He remembered the words his father had often said before he died: "Karl, when the earth begins to groan, you must learn what it is screaming."

He pulled out his phone and dialed a number he had saved for a long time but never once called. The screen lit up, and the green glow washed across his pale face.

"Helen, it's me. Karl."

The line crackled with a dial tone, then a calm, familiar female voice answered. "Karl? It's late—where are you? I looked for you at the Federal Archives and couldn't find you."

"I'm at the Metro Line Four construction site. Twelve meters below ground, Section B." Karl kept his voice low. "I found something. Some bones that… shouldn't be there. And they're being dug up right now."

Three seconds of silence on the other end, then the rustle of paper being turned. "Bones? You mean an ancient burial site?"

"No." Karl stared at the depression in the darkness ahead, where the black seemed deeper than the surrounding gloom. "Recent. Maybe within the last ten years. Helen, the bones have drill marks, and they're arranged in a pattern… like some kind of marking system. This isn't a natural geological layer. This is deliberate concealment. And right now, something living is digging."

"Something living?" Helen's voice tightened. "Karl, are you sure about that sound? It could be groundwater flow or pipe vibrations."

"No. Claws." Karl gripped his phone, his knuckles going white. "It sounds like wolves. Or something… modified into wolves. Helen, in the Luna Covenant, the page about the 'Watchers'—do you remember it?"

A soft intake of breath came through the phone. Helen O'Brien was a Federal Archivist and the only person who held surviving fragments of that century-old knight order's history. Luna—a mysterious organization that had vanished during World War II—was said to have guarded certain forbidden histories. Karl's father had been a peripheral member of Luna, and the circumstances of his death remained a mystery to this day.

"I don't remember a page on 'Watchers' at all." Helen's voice was dry. "Karl, you're in serious danger. That construction site is near Raymond Carter's zone of interest. If you're exposed now, he'll send lawyers and bodyguards to scrub the site clean. They'll explain it all away as a construction accident."

"So I need help." Karl said. "Nora Walker knows this site has unauthorized excavation. She's been tracing Raymond's money trail. If I call the police, Nora will come. But if I tell her directly it's Luna, she'll suspect I'm involved."

"Then just tell her it's a geological anomaly," Helen suggested. "Emphasize your professional judgment. Don't mention bones, don't mention wolves. Let her think it's an environmental risk. Explain once she's on site. But I have to warn you, Karl—Luna's Covenant carries a price. If you carry out their will, or touch an archive you shouldn't have, that price starts with your family's health. Your sister's asthma—has it been flaring up again recently?"

Karl's hand trembled. A drop of rain slid from the tip of his nose and splashed open into a small flower on the wet concrete floor. He thought of Judy O'Brien—his sister, a forensic scientist who had been complaining of sharp lung pains lately, though no tests could find a cause. That was Luna's warning.

"I know." Karl's voice was hoarse. "Helen, listen—that sound… it's digging deeper. If I'm reading this right, it's found something. Or it's clearing the site, preparing to haul away all the evidence."

"Can you stop it?"

"I'm just a railway engineer." Karl let out a bitter laugh. "But I know how to collapse ground. If I can map out the void below, I can use controlled detonations to seal that section off. But if I do that, the structural integrity of the site will be compromised, and Raymond will intervene immediately. He'll send a legal team, private security. He'll pin it all on 'a terrorist attack' or 'engineering negligence.' Then he'll wipe every record."

"Then why would you even do it?" Helen asked.

"Because the bones are numbered." Karl watched his flashlight beam scatter through the dust in the darkness. "The numbering format is identical to the label on that old photograph among my father's effects. Helen, if I can recover even one of them, Judy can determine the age and origin. This could prove that Luna never disbanded—that they've been using modern infrastructure projects to move illicit artifacts, and even… to dispose of certain 'special' individuals. It's the key piece of evidence in the laundering chain."

"The risk is too great." Helen said. "And that sound… Karl, are you sure it's an animal? A wolf pack under Los Angeles? Is it some rabid stray dog?"

"No." Carl drew a deep breath. "That's the 'Watchdog.' Luna's Watchdog. They've been modified—built for underground operations. Helen, I have to go. Nora will be here in ten minutes. I need you to check something: those paintings Raymond Carter acquired recently—what are their titles? Do any of them reference 'Lunar Eclipse' or 'Iron Rails'?"

"There's no direct connection. But there's an abstract piece called *Rusted Veins*."

"That's it." Carl said. "What's hidden in that painting—coordinates, maybe. Or a cipher. Helen, take care of yourself. If I don't check in by tomorrow, hand the copy I left on the third shelf of the filing cabinet to Judy. Whether I'm alive or…"

"Carl, don't say things like that." Helen cut him off. "You're just going to halt the construction. You're a professional. Trust your instincts. Now—hang up, get to cover."

The line went dead, and the dial tone sounded unbearably sharp in the silence of the underground space.

Carl switched off his phone screen and flicked the flashlight back on. He rose to his feet and walked toward the indentation. The sound was still there—click, click—the rhythm quickening, laced with a kind of anxious, furious energy.

He reached the edge of the indentation and crouched down. The beam swept across the rock face, catching the marks in its light. They were no ordinary scratch marks. At the tip of every single scratch, a small sliver of black metal was embedded—fragments of some kind of insignia.

Just then, a low growl rolled up from the depths of the darkness, thick with the hot, coppery stench of blood.

Carl didn't run. He drew the pry bar from his hip and pressed his back against the cold rock wall. He closed his eyes and felt the vibrations traveling up through the soles of his boots. His professional instinct told him there was a massive cavity beneath this wall, and that cavity was expanding fast. Whatever was "alive" in there was digging outward from within, and it was doing it at a terrifying pace.

If it broke through, the layer of earth above would pour in all at once, burying this entire section—him along with it.

He needed time. He needed Nora Walker.

Ten minutes earlier, Nora stood at the construction site entrance, rain soaking through her trench coat. She watched the security feed—Carl's figure far below, motionless—and her brow drew tight.

"He's still in there?" Nora asked the guard beside her.

"Yes, Agent. He said he's identified a severe structural hazard and requested the area be cordoned off. Manager Morris is livid, but he can't argue with Carl's blueprint analysis. Carl said if they don't reinforce it, five meters of overburden will cave in within ten minutes."

"Five meters?" Nora let out a cold laugh. "He's stalling. He's waiting for someone—or some piece of evidence."

"Chief, do we need to pull him out by force? Morris is threatening to sue the FBI for obstructing construction."

He had to gamble. Bet that on the far side of that fracture, his father's last letter was hidden, waiting.
