The roaring, metallic heartbeat of the Sub-Basin faded into the distance. Still, the underworld’s heavy heat clung to them as Samar limped slowly and rhythmically down the tracks, his boots crunching through the wet coal dust. Every few steps his right hand would instinctively twitch toward his left breast pocket. His fingers would brush against the outside of his long grey coat searching for the smooth, round shape of his silver pocket watch.
But there was nothing there. Only the flat, stiff fold of the grease-paper map Gideon had given him.
The pocket felt incredibly light. It was a cold, empty sort of lightness that seemed to pull at his chest. For three years that watch had been his anchor, a quiet, ticking reminder of a life that had been stolen from him. Now the ticking was gone. The silence in his pocket was louder than the distant crash of the steam pumps.
Beside him Ira walked in silence. She kept her hood pulled low, but the faint blue glow of her crystallized arm still managed to escape the folds of her wet cloak, casting long pale shadows on the rough stone walls. She kept glancing at Samar her amber eyes filled with a quiet heavy sorrow.
"You are thinking about the watch," she said softly, her voice barely louder than the dripping water above.
Samar did not look at her. He kept his eyes locked on the rusted mining rails stretching into the dark ahead. "I am thinking about the directions," he lied. "We need to make sure we do not miss the turn."
"You do not have to lie to me, detective," Ira said. She reached out with her right hand her fingers gently touching his grey sleeve. Her left arm remained stiff and lifeless against her ribs. "I know what that watch meant to you."
"The watch was just metal and gears Ira," Samar said, his voice flat and hard. "Metal can be bought. Gears can be replaced. Your life cannot."
"But it was the last thing you had of Esha," she whispered. "I saw the way you held it. You were holding onto her. And you gave it to a corrupt, greedy broker in the dirt just so I could live. I do not know how to carry that kind of debt Samar."
Samar stopped walking. He turned to face her, the dim orange light of a distant, flickering gas line catching the deep lines of his scarred face. "Then do not carry it," he said, his voice dropping to a low, serious rumble. "I did not trade the watch to put a burden on your shoulders Ira. I traded it because I chose to. In my life, I have let too many people slip into the dark because I was too slow or because I was following the Ministry’s rules. I am not doing it again. If we find this Alchemist, and we find a way to stop this glass from crawling up your shoulder, then the trade was worth it. That is the end of it."
Ira stared up at him, her lips parting slightly as if she wanted to argue. But as she looked into his tired, stubborn eyes she saw the absolute certainty in his face. Slowly she nodded, pulling her cloak tighter around her small frame.
"Gideon's map said we must take the third left branch," she said, shifting her focus back to the dark tunnel. "We have passed two side tunnels already. The next one should lead us straight into Sector 4."
"Then let's find it," Samar said, resuming his heavy, determined stride.
They walked for another five minutes before they found the opening. The third branch was narrower than the main line, the stone walls are rough and unfinished. Giant, jagged teeth of black bedrock hung low from the ceiling, forcing Samar to keep his head bowed. The ground here was steep, sloping downward into a deep yawning throat of absolute darkness.
The air was changing. It was no longer just hot and damp; it was growing thick and heavy carrying a strange, sweet pressure that made Samar’s ears pop. The metallic smell of sulfur was incredibly strong, mixed with the sharp, smell of raw, unrefined Aetheria.
Samar pulled the folded grease-paper from his pocket. He held it close to the faint blue light radiating from Ira’s arm, his eyes scanning the rough hand-drawn lines.
"This is Sector 4," Samar said, his brow furrowing as he read Gideon's messy handwriting. "The deepest excavation shaft of the old Ministry lines. Gideon wrote a warning here. Watch the steam valves. If they are venting green, you wait. If they are venting white, you run."
"And what if they are not venting at all?" Ira asked, her eyes scanning the dark pipes running along the ground.
"Then we pray the pipes aren't about to burst," Samar muttered, tucking the map back into his coat.
As they descended deeper into the narrow tunnel, a low pulsing sound began to vibrate through the soles of their boots. It was not the rhythmic mechanical thud of the Sub-Basin pumps. This was a deeper more organic sound—a low, hollow hum that sounded like a massive sleeping beast breathing deep within the earth. It was a sound that seemed to vibrate inside Samar's very bones, making his teeth ache and his chest feel tight.
"Do you hear that?" Ira whispered, her hand instinctively grabbing her crystallized elbow. The blue veins beneath her dark glass skin were starting to pulse faster, glowing with a sudden, restless intensity.
"The hum of the deep lines," Samar said, his hand sliding into his coat to grip the cold wooden handle of his revolver. "The closer we get to the raw veins, the stronger it gets."
"It is not just a sound, Samar," Ira said, her voice trembling slightly. Her amber eyes looked wide and glassy, the small blue rings around her irises flaring with light. "It is a voice. It is... it is so loud down here. It is like a million people are whispering directly into my ears but they are all speaking at the exact same time. They are crying."
"Do not listen to them, Ira," Samar warned, his voice sharp. "Focus on my voice. Keep your mind here with me. The raw fluid can play tricks on your mind if you let it in."
"I am trying," she gasped, her steps becoming slightly uncoordinated. "But the air... the air is so heavy."
Suddenly, a distant, terrifying sound echoed through the tunnel.
It was a sharp, high-pitched scream. It was followed immediately by the sound of scrambling footsteps and the desperate echoing shouts of men in absolute terror.
Samar instantly pulled his heavy revolver from his pocket his thumb pulling back the iron hammer with a sharp mechanical click. He pushed Ira behind his tall broad shoulder, his eyes locking onto the dark curve of the tunnel ahead.
"Someone is coming," Samar whispered.
Through the darkness, three figures burst around the corner. They were miners their faces completely black with coal dust, their heavy leather aprons torn and covered in wet mud. They were running blindly, their eyes wide with a wild terror. One of them had dropped his brass lantern, which dragged behind him on a copper chain, clattering loudly against the iron rails.
"Run!" the lead miner screamed his voice cracking with hysteria as he saw Samar and Ira. He did not even slow down. He scrambled past them, his hands clawing at his own neck as if he were trying to tear his skin off. "The red! The red is coming! The god is bleeding!"
"Wait!" Samar shouted, reaching out with his left hand to grab the second miner’s shoulder. "What happened? What is ahead?"
The miner twisted violently out of Samar's grip, his face twisted in a mask of pure madness. He stared at Samar but his eyes were not focused on the detective’s face. He was staring at the empty air behind Samar, his teeth bared in a silent, terrified scream.
"The fingers!" the miner screamed, pointing a trembling, mud-stained hand into the dark. "The glass fingers are coming out of the walls! They are pulling us in! They are pulling us into the furnace!"
With a desperate wild heave, the miner broke away and sprinted after his companions, their frantic footsteps quickly fading into the dark toward the Sub-Basin.
"They are out of their minds," Samar muttered, his grip on his revolver tightening. "That wasn't just fear. That was delirium."
"The Crimson Vapor," Ira whispered, her voice filled with sudden realization. She pointed her right hand toward the bend in the tunnel ahead.
A faint, ghostly light was beginning to creep around the corner. But it was not the cold, electric blue light of refined Aetheria. This light was different. It was a thick, purplish-crimson glow that crawled along the ceiling like a living glowing fog.
The air in the tunnel instantly grew sweet—sickeningly, intensely sweet, like the smell of rotting fruit mixed with burning copper.
"A leak," Samar said, his mind quickly analyzing the danger. "High-pressure unrefined Aetheria reacting with the sulfur and the copper-heavy moisture in this sector. The miners call it the Crimson Vapor. It’s a highly concentrated hallucinogenic gas."
"We cannot go back, Samar," Ira said, her breath coming in short, panicked gasps as she watched the red fog slowly roll toward them. "If we turn back to the Sub-Basin, the Ministry’s enforcers will have the exits sealed. We have to go through."
"Pull your cloak over your mouth," Samar ordered, ripping a clean, dry cotton handkerchief from his inner pocket and wrapping it tightly around his own nose and mouth. "Do not breathe it in deeply. Keep your steps steady and whatever you see, remember it is not real."
"I... I do not think the gas affects me the same way," Ira said, her eyes fixed on the approaching crimson mist. "My arm... it is already part of the dream. But you... Samar, your mind is vulnerable."
"I have survived thirty years of the city’s poisons, Ira," Samar said, his voice muffled by the cloth. "I can survive a little fog. Move."
They stepped forward, entering the swirling crimson cloud.
The moment the red vapor enveloped them, the world changed.
The transition was not sudden; it was a slow, terrifying warping of reality. The rough stone walls of the mining tunnel began to shimmer, the dark rock face turning smooth, glossy, and wet. The coal dust on the ground began to glow with a faint, pulsing red light, looking like hot, dying embers.
Samar felt a sudden sharp pressure behind his eyes, a localized throb that made his vision blur. The sweet smell of the gas penetrated the cotton cloth, coating the back of his throat with a warm, metallic film.
Tick-tick-tick.
Samar froze.
The sound was small, steady, and incredibly clear. It was the sound of his silver pocket watch, ticking away inside his coat pocket.
He reached his hand down, his fingers instantly brushing against the pocket. His heart hammered against his ribs as his fingers felt the distinct round shape of the silver case. He pulled it out. The tarnished silver case caught the red light of the fog, the delicate leaves engraved on the metal looking like real, living vines wrapping around the silver.
He clicked the case open. The tiny, gold-plated gears inside were spinning in perfect, mechanical unison. But as he watched, the white paper face of the watch began to turn wet. A dark, crimson fluid began to seep from behind the metal hands, pooling over the numbers and dripping onto his leather glove.
"No," Samar muttered, his voice shaking. "I gave it to Gideon. I do not have it."
"Samar!" Ira’s voice sounded incredibly distant, as if she were speaking to him from the bottom of a deep well. "What are you doing? Why did you stop?"
Samar looked up, but the tunnel was no longer there.
The stone ceiling vanished. In its place stretched a vast, endless vault of solid black glass. Above, millions of tons of dark crystal pressed down—heavy, silent, and suffocating. The rusted mining rails beneath his boots had turned into giant, skeletal iron arms that reached up from the ground, their metal fingers twitching as they tried to grab his legs.
From the walls of the cavern, thousands of silent, frozen statues of black glass stared at him. They were the miners who had vanished, the poor whom the Ministry had buried in the dark. And in the center of them all, stood a tall elegant figure with long, dark hair that smelled of lavender.
"Esha," Samar whispered, the handkerchief slipping from his face as his hand dropped to his side.
The figure turned slowly. Her face was soft and beautiful, exactly as he remembered it from the rainy autumn night she had walked out of his life. She wore her simple, faded blue wool coat, her small hands tucked into her pockets. She looked at him with a quiet, gentle smile that made his chest ache with a sudden, overwhelming wave of grief.
"Samar," she said, her voice a soft, beautiful whisper that cut through the heavy hum of the deep lines. "You found me."
"Esha, I... I have been looking for you," Samar gasped, taking a step toward her. His bad leg did not hurt anymore; the pain had vanished replaced by a strange, weightless warmth that made him feel like he was floating. "I have been in the dark for so long."
"I know, my love," she said, holding out a pale, warm hand toward him. "But the dark is over now. You can let go. You do not have to carry the weight anymore. Come with me."
Samar reached out his right hand, his fingers trembling as he tried to touch her warm skin. He wanted nothing more than to step into her shadow, to let the empty, cold ache in his chest finally heal. He wanted to close his eyes and let the ticking of the watch fade away forever.
"Samar, no!"
A sudden, violent shockwave of blue light shattered the vision.
Ira’s crystallized left arm was glowing with a blinding, electric intensity, the pulsing blue veins inside the black glass casting a sharp, cold light that cut through the crimson fog like a knife. She had grabbed Samar’s right arm with her small human hand, pulling him back with all her strength.
"It is not real!" Ira screamed, her amber eyes wide with panic as she stared at his blank, glassy eyes. "Samar, look at me! She is not there! The gas is rewriting your mind!"
Samar stumbled, his boots catching on the real, rusted mining rails. He looked at the space where Esha had been standing, but there was only a thick, swirling column of purple-crimson mist, venting violently from a cracked copper pipe on the wall.
The black glass vault was gone. The skeletal iron arms were gone. The heavy, suffocating pressure of the stone ceiling returned, pressing down upon his shoulders like a physical weight.
His bad knee buckled, a sharp, white-hot needle of pain shooting straight into his hip, reminding him with brutal clarity that he was still alive, still broken, and still in the dark.
"Esha," Samar muttered, a single tear cutting a clean path through the black soot on his cheek.
"We have to move, Samar!" Ira gasped, her voice strained as she struggled to support his heavy weight. The blue light of her arm was flickering violently, her body shivering from the intense magical output. "The pressure in these pipes is rising. If we stay here, the gas will choke us to death. Close your eyes! Trust me!"
Samar closed his eyes, his chest rising and falling in shallow, ragged gasps as he forced his mind to focus on the cold reality of the pain in his leg. He wrapped his right arm around Ira’s shoulders, letting her guide him through the blinding, glowing fog.
Ira walked slowly, her steps steady and deliberate. She did not look at the warping stone walls, and she did not listen to the whispering voices that rose from the red mist. Her crystallized left arm seemed to act as a compass, the blue veins inside the glass pulsing in harmony with the flow of the energy in the tunnel. She could feel the raw currents of the Aetheria, navigating them through the dense pockets of gas as if she could see the clean paths in the dark.
"Almost there," Ira whispered, her teeth clicking together. "The air... the air is clearing ahead."
They turned a final, sharp corner, and the sweet, suffocating aroma of the unrefined fluid began to fade. The swirling crimson fog grew thin, dissolving into a cold, damp draft that blew from a wide, open cavern ahead.
Samar opened his eyes and let out a long, ragged breath, sliding down the rough stone wall to sit heavily on the dry coal dust. He pulled the wet cotton handkerchief from his face, his lungs aching as he breathed in the cool, sulfurous air of the clean sector.
"Are you alright?" Ira asked, kneeling beside him in the dark. The blue glow of her arm was dimming, retreating back beneath her wet sleeve, but her face was incredibly pale and covered in sweat.
Samar did not answer immediately. He stared down at his empty, leather-gloved hands. The silver pocket watch was gone; the crimson blood was gone. His hand in his pocket found only the dry grease-paper map.
"She was so real, Ira," Samar whispered, his voice cracking with a raw, vulnerable grief he had kept hidden for three years. "I could smell the lavender in her hair. I could see the way her coat folded. For a second... I wanted to stay there. I wanted to let the glass take me."
Ira looked down at her own crystallized hand, her fingers tracing the hard, cold surface of the black glass. "I know," she said softly. "The dream is beautiful, Samar. It promises you everything you have lost because it wants you to stop fighting. It wants you to become a vessel so it can wake up. But if you stay in the dream, you die."
"I am not going to die in this dirt," Samar said, his voice hardening as the cold, sharp focus of the detective slowly returned to his eyes. He grabbed a rusted iron pipe on the wall and pulled his weight up, forcing his bad leg to carry him. "And I am not going to let this city turn you into a statue. Let's find this Alchemist."
"Look," Ira said, pointing her hand toward the center of the massive cavern ahead.
The cavern was silent. Only the distant roar of a high-pressure steam valve echoed through the dark. But in the center of the dark space, a colossal bone-white structure emerged from the shadows, like a pale, petrified monster lurking in the dark.
It was the calcified skull of a giant prehistoric sea beast, buried in the solid stone of the underworld millions of years before the city of Oakhaven was even built. The massive, hollow eye sockets of the creature stared out into the dark, and its giant, jagged jaw was frozen in a permanent, terrifying yawn.
Deep inside the hollow nasal cavity of the ancient skull, a single, dirty glass lantern flickered weakly, its blue flame casting long, dancing shadows across the bone-white walls.
"The Alchemist’s laboratory," Samar whispered, his hand sliding back into his coat pocket to grip his heavy revolver.
"We made it," Ira said, her amber eyes bright in the dark.
They stepped onto the crumbling stone path that led toward the giant skull, leaving the crimson fog and the whispers of the past behind them, ready to face the creator of the mutated strain at the very bottom of the world.
