The "Echo" was a place of barter, where life was measured in grams of copper and the potency of stabilized mana-cells. To get the medicine Liora needed, Marcus and Kael couldn't just go to a pharmacy; they had to visit the Vault, a fortified bunker deep in the ruins where the "Merchant of Souls" held
Chapter 10: The Merchant of Souls
The Vault was a relic of the Old World, a massive hemispherical structure of reinforced lead and Dead-Stone that had once served as a fallout shelter for the high-ranking scientists of the ruins. Now, it was draped in flickering neon tubes and guarded by two men with cybernetic arms and heavy-gauge kinetic rifles.
"Copper is up, Marcus," one of the guards grunted, eyeing the heavy bags Kael was carrying. "The Sanctum is squeezing the supply lines above. Silas is in a foul mood. Keep your hands where he can see them."
Marcus nodded, his hood pulled low to hide the black veins that had begun to pulse rhythmically against his jawline. Inside, the Vault smelled of ancient air and expensive tobacco—a jarring contrast to the sulfur and rot of the Low-Grid.
At the center of the room sat Silas, a man who looked like he had been stitched together from a dozen different corpses. He was ancient, his skin a translucent parchment, and he sat in a hovering chair that hissed with pressurized steam. Behind him, rows of glass jars filled with glowing liquids and preserved monster organs lined the walls.
"Ah, the Little Shadow and the Mechanic," Silas wheezed, his voice sounding like dry leaves skittering across pavement. "You bring me scrap, and you ask for the blood of the gods."
Kael stepped forward, slamming the bags of high-grade copper onto the metal table.
"It's top-tier, Silas. Pulled from the 4-B ventilation hub. No oxidation. Clean as a whistle."
Silas reached out a skeletal hand, his fingers dancing over the coils. He closed his eyes, sensing the conductivity.
"Acceptable. But the price of Liora's stabilizers has tripled. The Sanctum's 'Project Omni-Reach' is demanding every drop of refined gravity-serum for their own... experiments."
Marcus felt the shadows beneath his feet grow cold.
"Triple? We risked our lives for this, Silas. You're price-gouging refugees."
Silas opened one eye—a milky, clouded thing that seemed to see right through Marcus's hood.
"I am a businessman, 00560. I do not gouge. I survive."
Marcus froze at the mention of the number. He didn't move, but the air in the room suddenly grew heavy. The shadows didn't spike; they deepened, turning the light from Silas's neon tubes into a sickly, dim flicker.
"How do you know that number?" Marcus
asked, his voice a low, vibrating growl.
Silas chuckled, a wet, rattling sound.
"I've lived in these ruins since before your father was a 'Zero,' boy. I've seen hundreds like you come through these pipes. Numbers etched into their souls, gifts that feel like gods, and eyes full of a fear they can't name."
He leaned forward, the steam from his chair hissing.
"You think you're special? You think the Shadow Creator chose you because of your 'potential'? You are a variable in an equation that was written before the city of Oakhaven was a blueprint. I've seen 00550, 00551... I even remember 00400. He was a fire-bringer. He burned for three days before the heat turned his own bones to ash."
Marcus felt his heart hammer against his ribs.
"What happened to them? The others?"
"They failed the grind," Silas said, reaching into a hidden compartment in his chair and pulling out a small, pressurized vial of violet liquid—the medicine for Liora. "They tried to be heroes. Or they tried to be villains. They didn't realize that the Creators don't want a king. They want a perfected result. When a subject stops being useful, the Creator simply... deletes the file."
Silas tossed the vial. Marcus caught it with a reflex that was too fast for a human, his shadow snapping up to cushion the glass.
"That vial will keep the girl's gravity from collapsing for another two weeks," Silas said. "But the copper only pays for the medicine. If you want the truth about the 'Experiment,' you'll have to bring me something more valuable."
"What?" Marcus asked.
"There is a sector deeper than the Low-Grid. The Core-Well," Silas whispered, his eyes gleaming with greed. "A probe from the Creator of Light, Rial, crashed there three days ago. It carries a 'Data-Shard.' Bring me that shard, and I will tell you the name of the being who is currently watching you from the stars."
Kael gripped Marcus's arm. "Marc, no. The Core-Well is suicide. The pressure alone will crush us, and the guardians there aren't Husks. They're 'Old World' automatons."
Marcus looked at the vial in his hand. He thought of the dream—Liora being pulled apart by the vortex. He thought of Subject 00561 and the golden, mocking eyes.
"I'll do it," Marcus said.
"Marcus!" Kael hissed
"I need to know, Kael," Marcus said, turning to his friend. His eyes were no longer brown; they were a dark, bruised violet that seemed to swallow the light of the room. "If I'm just a number, I need to know why. Because the moment I understand the rules of the game, I can start breaking them."
As they turned to leave, Silas called out one last time.
"A word of advice, 00560. The 'Spatial' girl you met last night? She isn't here to help you. She's a 'Scout.' Every Creator has their own eyes in the dark. Do not confuse a 'Rival' with a 'Teacher.'"
Marcus didn't look back. He walked out of the Vault and into the cold, damp air of the ruins. The weight of the medicine vial felt like a lead weight in his pocket.
The "Grind" had just taken a sharp turn. He was no longer just scavenging for food; he was scavenging for his own identity.
"Kael," Marcus said as they navigated the dark pipes back toward the Echo. "Take the medicine to Liora. I'm going to the Core-Well tonight."
"You're going to die, Marc," Kael said, his voice cracking with emotion. "You can't even hold your sword without your shadows helping you now. You're changing. Every time you use that power, you become less like the Marcus I grew up with."
Marcus stopped. He looked at Kael, the boy who had stayed by his side even when he was a "Zero."
"Then I'll be the monster that keeps you safe," Marcus said.
He didn't wait for a reply. He stepped into the shadows of a massive support pillar and simply... vanished. It wasn't a teleport; he had "slipped" into the space between the shadows, a trick he had learned by watching Elara.
Kael stood alone in the dark, clutching his tools. "I'm not letting you go alone, you idiot," he whispered to the empty air.
Deep in the cosmic laboratory, a bell chimed.
