The Iron Lung did not glide; it marched.
The massive supply train pounded the frozen tracks of the Trans-Siberian Arterial Line with a rhythmic, bone-shaking violence that made sleep impossible. Inside the rear cargo car, the Swahili Pack huddled around a small, scavenged heater, listening to the wind howl outside the armored plating.
"We have been moving for six hours," Upepo whispered, vibrating his leg to keep the blood flowing. "And we haven't seen a single guard. It's quiet. I hate quiet."
"It's automated," Bahati said, his eyes glued to the holographic schematic of the train he had pulled from the rear console. "The first ten cars are just raw ore and supplies. But car eleven..."
He tapped the screen. A section of the train was highlighted in pulsing red.
"Car Eleven is shielded," Bahati muttered. "Lead-lined walls. Independent power supply. And look at the thermal signature."
He projected the heat map. The rest of the train was blue (freezing). Car Eleven was a deep, angry crimson.
"It's hot?" Sia asked, leaning in. "Like the Firebird?"
"No," Bahati shook his head. "The Firebird is dry heat. This is... biological heat. Wet heat. And it's massive. Whatever is in there is generating enough metabolic energy to power a small city."
"Maybe it's livestock?" Chacha suggested, chewing on a piece of dried ration bar. "The Tsar needs to eat."
"The Tsar eats hope, not cows," Yelena said darkly. She was cleaning her plasma rifle, her movements sharp and angry. "The Iron Lung brings the 'Blood of the Earth' to the Kremlin. But the miners in the deep pits... they talk about other shipments. Shipments that scream."
Amani stood up. The mention of screaming shipments settled heavily in his gut.
"We need to move forward anyway," Amani said. "We can't take control of the engine from the caboose. We have to clear Car Eleven to get to the locomotive."
"Darius," Amani turned to the guide. "You know the Giza protocols. What transports biological heat in a supply train?"
Darius was sitting in the shadows, his eyes closed. "Many things, Amani. Bio-Fuel. Genetic experiments. Or... prisoners."
Darius opened his eyes. They were cold. "We should prepare for the worst. In the Tundra, the worst is usually the truth."
The Walk of Steel
They moved out.
Crossing between the cars of the Iron Lung was a death wish. The train was moving at two hundred miles per hour. The space between the carriages was an open-air platform exposed to the freezing wind and the deafening roar of the wheels.
"Watch your step!" Amani yelled over the wind, grabbing a frozen handrail.
They leaped across the gap, the tracks blurring beneath them like a grey river. They entered Car Ten—a munitions depot filled with crates of Cryo-Shells.
"Don't touch anything," Bahati warned. "These shells are unstable. One spark and this whole train becomes a crater."
They crept through the munitions car, the tension palpable. Every rattle of the tracks made Chacha flinch, eyeing the explosives stacked to the ceiling.
They reached the door to Car Eleven.
It was different. It wasn't the standard rusted iron of the other cars. It was a sleek, heavy slab of Titanium-Alloy, etched with warning runes in glowing red light.
"RESTRICTED. BIO-HAZARD CLASS 5. AUTHORIZED PERSONNEL ONLY."
"Class 5?" Bahati whispered. "That's the same classification they used for the Deep-Striders."
"Stand back," Chacha grunted, raising his hammer.
"No!" Bahati stopped him. "If you hit this door, the anti-tamper mechanism will vent the car into space. We need a key."
They all looked at Darius.
Darius stepped forward. He looked at the keypad. It wasn't digital. It was a Genetic Scanner. It required a drop of blood from a High-Ranking Officer.
"I cannot open this," Darius lied smoothly. "My clearance was revoked when I 'died' in Cairo. My blood is not in the active database."
"Then we hack it," Bahati said, cracking his knuckles. "I need five minutes."
"You have two," Yelena said, pointing to a camera in the corner. "The security sweep is cycling."
Bahati worked fast. He jammed his Null-Engine gauntlet into the panel. He didn't try to crack the code; he tricked the sensor. He used a synthesized loop of data he had recorded from the White Wolf back in the train yard.
BEEP.
"IDENTITY CONFIRMED. WELCOME, COMMANDER."
The massive door hissed. The pneumatic seals unlocked with a sound like a dying breath.
The door slid open.
The Carriage of Ghosts
The smell hit them first.
It wasn't the smell of rot. It was the smell of Preservation. Formaldehyde, sterile ozone, and copper blood.
They stepped inside.
The car was huge—much longer on the inside than it appeared from the outside, expanded by Giza spatial-folding tech. It looked like a laboratory.
Lining the walls, stacked three high, were hundreds of transparent, cylindrical pods.
Inside each pod was a person.
They were floating in a thick, amber liquid. Tubes were connected to their spines, their chests, and their temples. Their eyes were open but unseeing, glazed over with a milky white film.
And they were glowing.
A faint, blue light pulsed from their bodies, traveling up the tubes into a central conduit running along the ceiling.
"Ancestors preserve us," Sia whispered, clamping a hand over her mouth.
"They're... batteries," Bahati said, his voice shaking as he read the data on a nearby console. "Look at the flow rate. The train is draining their Mana. Their life-force. It's siphoning it directly into the engine."
Yelena walked slowly down the aisle. She looked at the faces in the pods. Men. Women. Children.
She stopped at a pod near the center.
Inside was a young man with a scar on his cheek. He was thin, emaciated.
"Ivan," Yelena whispered. She placed her hand on the glass. "This is Ivan. He was my lieutenant. He went missing three months ago during a patrol."
She looked at Amani, tears of rage freezing in her eyes. "We thought they killed him. We thought he was dead."
"This is worse than death," Darius said quietly. He walked up to a pod containing an old woman who was clearly a Shaman of the old ways. "The Tsar uses the Fragment of Body to make himself invincible. But invincibility requires fuel. The Fragment consumes entropy. To stop his body from aging, he has to feed it... life."
"So he's eating them?" Upepo asked, looking sick.
"He is burning them," Darius corrected. "Like coal."
Suddenly, the liquid in Ivan's pod bubbled. His eyes moved. They focused on Yelena.
His mouth opened. No sound came out, but his lips formed a word.
Run.
The Warden
From the shadows at the far end of the car, a figure emerged.
It wasn't human. It was a Giza Bio-Warden.
It looked like a surgeon's nightmare. It floated on anti-gravity repulsors, having no legs. Its torso was a mess of robotic arms, each holding a different medical instrument—scalpels, saws, syringes. Its head was a glass dome filled with the same amber liquid as the pods, containing a floating human brain.
"UNAUTHORIZED BIOLOGICALS DETECTED," the Warden's voice buzzed. It sounded like a swarm of flies. "THE HARVEST IS NOT COMPLETE. YOU ARE EARLY."
"We aren't the harvest," Chacha growled, stepping in front of Yelena. "We're the demolition crew."
"INCORRECT," the Warden droned. "ALL LIFE IS HARVEST. PREPARE FOR PROCESSING."
The Warden raised its four arms.
From the ceiling, automated turrets dropped down. But they didn't fire bullets. They fired Paralysis Darts.
"Cover!" Amani yelled.
He grabbed a metal medical trolley and flipped it over, creating a makeshift shield just as the darts pinged off the steel.
"Sia! The brain!" Amani ordered.
Sia popped up and fired an arrow. The shaft struck the Warden's glass dome.
PING.
The glass didn't break. It was reinforced diamond-glass.
"INEFFICIENT," the Warden mocked.
It surged forward, its repulsors whining. It lashed out with a robotic arm tipped with a monofilament saw.
Chacha blocked with his Cryo-Hammer. Sparks flew. The saw cut deep into the hammer's head, screeching like a banshee.
"It cuts through Giza iron!" Chacha yelled, straining to hold the machine back.
"Bahati! Can you hack it?" Amani shouted.
"It's organic!" Bahati yelled back. "The brain inside is controlling the tech! I can't hack a human brain with a Null-Engine!"
"Then we burn it!" Darius said.
Darius didn't use shadow magic this time. He grabbed a canister of the amber preservation fluid from a shelf.
"Upepo! Catch!"
Darius threw the canister into the air above the Warden.
"Sia! Fire arrow!"
Upepo blurred. He didn't catch the canister; he punched it. The canister exploded, showering the Warden in the flammable amber liquid.
Sia fired a "Fire-Gazelle" arrow.
WHOOSH.
The liquid ignited. The Warden was instantly engulfed in blue flames.
"ERROR! TEMPERATURE CRITICAL! COOLING SYSTEMS FAILING!"
The machine shrieked. It spun wildly, its saw arms flailing.
"Now!" Amani roared. "Chacha! Smash the dome!"
Chacha roared. He swung his hammer with everything he had. The heat from the fire had weakened the glass.
"SIMBA!"
CRASH.
The hammer shattered the glass dome. The brain inside, exposed to the freezing air and the fire, pulsed once and then died.
The machine collapsed to the floor, twitching.
The Choice
Silence returned to the car. The only sound was the bubbling of the pods and the crackling of the small fire, which Darius quickly smothered with his cloak.
"It's dead," Chacha panted, kicking the wreckage.
Yelena ran to Ivan's pod. She grabbed the release lever.
"I have to get him out," she cried. "I have to save him!"
"Stop!" Bahati yelled, grabbing her hand.
"Let me go!" Yelena screamed.
"Look at the monitor, Yelena!" Bahati pointed to the screen. "His vitals are tied to the machine. His heart isn't beating on its own. The amber fluid is the only thing keeping him alive. If you open that pod... he dies in seconds."
Yelena froze. She looked at Ivan. He was staring back at her, his eyes pleading.
"We can't save them here," Bahati said softly. "Not on a moving train. We don't have the medical equipment to wean them off the system."
"So we leave them?" Upepo asked, horrified. "We leave them to be eaten by the engine?"
"No," Amani said. He walked up to the central conduit—the pipe sucking the energy from the pods.
"We cut the feed," Amani said. "Bahati, can you bypass the drain? Can you put the pods into 'Stasis Mode' so they stop feeding the engine but keep the people alive?"
Bahati looked at the console. "I can loop the system. I can make the engine think it's getting power while keeping the prisoners in suspension. But..."
"But what?"
"If we cut the power to the engine," Bahati said, "the train slows down. The Tsar will know something is wrong. We'll lose the element of surprise."
Amani looked at the hundreds of people in the pods. He looked at Ivan.
"Screw the surprise," Amani said. "We don't trade lives for tactics. Do it."
Bahati nodded. He typed furiously.
"SYSTEM OVERRIDE. INITIATING STASIS PROTOCOL."
The blue light in the tubes dimmed. The pulsing stopped. The people in the pods relaxed, drifting into a deeper, safer sleep.
The train lurched. The hum of the engine dropped an octave. They were slowing down.
"We bought them time," Amani said. "But now the clock is ticking for us. The automated defenses will be alerting the Kremlin right now."
The Oath
Yelena placed her hand on the glass of Ivan's pod one last time.
"I will come back for you," she whispered. "I promise."
She turned to the Pack. Her face was no longer just angry. It was resolved.
"The Tsar has taken everything from us," Yelena said. "He took our sun. He took our warmth. And he took our people."
She racked the slide of her plasma rifle.
"Let's go to the front of the train," Yelena said. "I want to look him in the eye when we burn his house down."
Amani nodded. He checked his gear.
"Darius," Amani said. "How many cars left?"
Darius looked at the door leading to the next carriage.
"Thirty-nine," Darius said. "And if this car was the battery... the next ones will be the weapons."
"Good," Chacha grinned, hefting his hammer. "I was getting bored of punching glass."
The Pack formed up. They left the Carriage of Ghosts behind, moving forward into the belly of the beast.
Outside, the lights of the Kremlin Defense Grid began to appear on the horizon. A massive wall of laser towers and ice-cannons, guarding the heart of the sector.
They were driving straight into it.
