The rain hadn't stopped since we left the auction house. It drummed relentlessly against the corrugated metal roof of the warehouse, a chaotic rhythm that tried to drown out the sound of our own breathing. But it couldn't drown out the sound of the Heart.
Thump. Pause. Thump.
It sat on the central workbench, encased in its lead-glass prison. The Heart of the Chimera wasn't just an organ; it was a biological engine. With every beat, a pulse of sickly green light washed over the peeling paint of the walls, casting long, dancing shadows that looked too much like grasping claws.
Cian was sitting on a crate, staring at it. He had taken off his mask, but his face still looked pale and waxy in the verdant glow. He held a glass of whiskey that trembled slightly in his hand.
"It's alive," Cian whispered, his voice barely audible over the rain. "We just spent fifty-two thousand gold on a piece of meat that is still alive."
"It's not alive, Cian. It's animated," I corrected, adjusting the magnification on my goggles. I was already dissecting it with my eyes, stripping away the mystery to find the mechanics underneath. "It's a muscle that reacts to mana stimulus. It's no different than a pump."
"It belonged to a monster," Zane grunted from the corner. He was sharpening his sword, the rhythmic shhhk-shhhk of the whetstone providing a grim counterpoint to the heartbeat. "A Chimera. Those things eat people. Are we sure this thing won't try to eat the centrifuge?"
"If we build the containment unit correctly, it won't eat anything but raw mana stones," I said, picking up a wrench. "Now, help me open the main intake valve. We have work to do."
By the time the sun began to bleed through the grimy windows of the warehouse, the storm outside had passed, leaving behind a grey, suffocating humidity. Inside, the air was heavy with the metallic tang of copper and the ozone smell of magic.
We hadn't slept.
The centrifuge was gone. In its place stood something new. Something terrible. I had cannibalized the old machine, stripping it down to its skeleton. Around that skeleton, I had grafted the new parts we had scavenged or bought. The Heart was now installed at the core, suspended in a vat of conductive gel. Tubes and wires snaked out from it like arteries, connecting it to the distillation chambers.
It looked less like an alchemy tool and more like a torture device.
"Integration complete," I announced, wiping grease and sweat from my forehead. My hands were shaking from exhaustion, but my mind was wired, buzzing with the caffeine of pure creation. "Systems check."
Cian stood up. He looked like a ghost of the pristine noble he usually was. His silk shirt was ruined, stained with oil and coolant. He walked over to the control panel, his hand hovering over the primary lever.
"If this explodes," Cian said, his voice flat, "I won't even be mad. I'll just be relieved I don't have to explain the bankruptcy to my father."
"Optimism," I said. "Pull it."
Cian closed his eyes and pulled the lever.
For a second, nothing happened. Then, the Heart skipped a beat. THUMP-THUMP. The green light intensified, turning from a dull glow to a blinding flare. The conductive gel in the vat began to boil. A low hum started, deep and resonant, vibrating through the soles of our boots.
The pipes hissed. The gears engaged. Clack. Whirrrr.
The machine didn't just turn on; it woke up. Raw mana stones in the hopper were crushed instantly, dissolved into vapor, and sucked into the core. The Heart pumped, forcing the vapor through the refinement coils at a speed that defied physics.
Drop by drop, the blue liquid began to fall into the collection beaker. But it wasn't the slow drip of our old machine. It was a steady stream.
"Look at the purity," I whispered, checking the gauges. "98%. It's refining the impurities almost instantly."
Zane walked over, his eyes wide. "How fast is it going?"
I did the math in my head. "At this rate... we can produce a hundred vials an hour. Two thousand a day."
Cian stared at the stream of Aether Tonic. He did his own math. The merchant math. "Two thousand vials," he murmured. "At 150 gold each... that's 300,000 gold a day. In revenue."
He looked at me, and for the first time in twenty-four hours, the fear left his eyes. It was replaced by a hunger that matched the machine's. "We're going to be richer than the King."
"Only if we can sell it without getting caught," I reminded him, shutting down the intake to prevent the beaker from overflowing. "This kind of production volume creates waves. The Guilds will notice. The market will fluctuate. We need to be careful."
The reality of our new life hit me hard during the History of Magic lecture three hours later. I was sitting in the tiered lecture hall, my body aching, my eyes burning. Professor Silas was droning on about the Goblin Wars of the Second Era, his voice a perfect lullaby.
I looked across the room. Cian was in his usual seat in the front row. He was immaculate again—clean uniform, styled hair, perfect posture. No one looking at him would guess that six hours ago he was covered in grease, staring into the heart of a monster. But I saw the slight tremor in his hand as he took notes. I saw the way he kept checking his pocket watch.
He wasn't thinking about Goblins. He was thinking about the machine.
A crumpled piece of paper landed on my desk. I unfolded it. Valerius is absent today.
I looked at the empty seat usually occupied by Torian. It was true. Torian wasn't there. And neither were his usual lackeys. That wasn't good. Torian was vindictive, but he was also disciplined. For him to miss class meant something major was happening at House Valerius.
I scribbled a reply: Wounded animal. Dangerous. Keep your head down.
I flicked the note back to Cian with a puff of air magic. He caught it without looking, read it, and burned it in his palm.
The bell rang, signaling the end of the torture. As I gathered my books, a shadow fell over my desk. I looked up to see a girl standing there. She had messy red hair, thick glasses, and ink stains on her fingers. She wore the uniform of the Artificer track. Elara Vance. (No relation to my fake identity).
"You're Aren, right?" she asked. Her voice was fast, nervous. "The guy who built the gauntlet?"
I tensed. The Spell-Driver was supposed to be a secret, or at least, a mysterious anomaly. "I don't know what you're talking about."
"Oh, come on," she rolled her eyes, adjusting her glasses. "I saw the scorch marks on Torian's armor in the infirmary. Kinetic impact, thermal discharge. That wasn't a spell. That was a shaped charge. A mana-accelerator."
She leaned in, her eyes gleaming with obsessive curiosity. "I want to know how you stabilized the containment field. Did you use copper or mithril for the coils? The thermal expansion alone should have blown your arm off."
I stood up, slinging my bag over my shoulder. "I think you have me confused with someone else, Elara. I'm just a theory student."
"Liar," she grinned. "I checked your library records. You checked out 'Thermodynamics of Mana' and 'Advanced Metallurgy'. Nobody reads those for fun."
She blocked my path. "Look, I don't care about the politics. I don't care that you blasted that jerk Torian. I just want to see the tech. I'm... stuck. I'm trying to build a mana-battery, but I can't get the storage density high enough."
I looked at her. [Name: Elara Vance] [Class: Artificer (B-Rank)] [Trait: Technophile]
In the game, Elara was a minor NPC who sold upgrades. But here, she was a genius held back by traditional magic theory. We needed an engineer. I knew the theory from Earth, but I lacked the hands-on crafting skills for the finer details. I couldn't build the automaton bodies alone.
"I can't help you," I said, walking past her.
"I have access to the Scrap Yard," she whispered behind me.
I stopped. The Scrap Yard. The Academy's graveyard for failed magical experiments. It was a treasure trove of rare metals and parts that couldn't be bought on the open market. I turned back slowly.
"The Scrap Yard is restricted to Faculty," I said.
"My uncle is the Groundskeeper," she smirked. "I have a key."
I looked at Cian, who was waiting for me by the door. He raised an eyebrow. Is she a threat? I looked back at Elara. She wasn't a threat. She was a resource.
"Meet me behind the old clock tower at midnight," I said quietly. "Bring the key. And if you tell anyone, I'll tell Professor Silas you're the one who enchanted his chair to squeak every time he sits down."
Elara's jaw dropped. "How did you know that?"
"I know everything," I said, and walked out of the room.
That night, the warehouse felt different. The machine was humming steadily, filling crate after crate with glowing blue bottles. Zane was asleep on his makeshift cot, the noise acting as white noise for him.
Cian was pacing. "Elara Vance," he said, rubbing his temples. "You invited a stranger to our secret base?"
"Not here," I said, checking the straps on my gauntlet. "I'm meeting her at the tower. We need parts, Cian. The Chimera Engine is powerful, but it's fragile. We need mithril shielding. We need heat sinks. She can get them."
"She's a loose end."
"She's an Artificer. She cares about the how, not the why. She won't sell us out to the teachers; she'd be too afraid of losing access to our tech."
Cian sighed, defeated. "Fine. But if she talks, you deal with her."
"Understood."
I opened the warehouse door to leave, but stopped. The night air was cold. But there was something else in the wind. A smell I recognized from the slums. Smoke. And alchemical fire.
"Cian," I said, my voice sharp.
"What?"
"Look at the sky."
Cian walked to the door. Over the skyline of Babylon, towards the East—where the Noble District lay—a pillar of green fire was rising into the clouds. It wasn't a normal fire. It was Wildfire. Magical arson.
"That's... that's the Valerius Estate," Cian whispered, his face going pale.
We watched as the flames danced, consuming one of the oldest mansions in the city. "Torian wasn't in class," I murmured. "His father was desperate."
"Who did this?" Cian asked. "Did we do this? Did the crash ruin them so badly that their enemies attacked?"
"No," I said, watching the green flames twist into the shape of a skull. "Enemies don't use Wildfire. It destroys the loot." I realized what was happening. "This isn't an attack, Cian. It's an exit strategy."
"What?"
"Lord Valerius is faking his death," I said, the pieces clicking into place. "He couldn't pay his debts. He couldn't face the shame. So he burns the house, claims everyone died, and runs away with whatever assets he has left."
"But... Torian..."
"Torian is probably with him. Or..." I hesitated. "Or Torian was the sacrifice."
The explosion echoed across the city, a dull boom that shook the ground beneath our feet. The game had changed again. We weren't fighting a rival House anymore. We were fighting ghosts. And ghosts were much harder to kill.
"Lock the door," I ordered, stepping back inside. "No meeting tonight. We go dark. Until we know who survived that fire."
The Chimera Engine beat in the background. Thump. Thump. It sounded less like a heart now, and more like a ticking clock.
