The fog didn't just hang over the water. It crawled.
It was a grey, sickly vapor that smelled of salt, rotted fish, and industrial waste. Solar stood at the edge of Pier 13, his leather coat snapping in the biting wind. Aethelgard's harbour wasn't a place for travel. It was a throat. A massive, rusted gullet that swallowed resources and spat out black bile. Below him, the dark water of the bay slapped against the barnacle-crusted pilings with a wet, rhythmic THUD.
"The shipment is late, sir. Three hours."
Elias was shivering. His breath came in ragged, white clouds that vanished into the fog. The boy looked like he was made of glass, ready to shatter under the weight of the cold. He held a rusted lantern that flickered—a dying yellow eye in the gloom.
"Time is a debt that the sea doesn't honor, Elias," Solar muttered. His voice was a cold rasp, barely audible over the groaning of the rusted cranes. "But the captain? The captain honors me. If he's late, it's because he's either dead or he's trying to hide something in the hull. Either way, someone is going to pay the penalty."
He looked out into the void. A massive silhouette emerged from the mist. The Leviathan's Ledger. A freighter that looked more like a floating fortress of scrap metal than a ship. It didn't glide; it labored. Every churn of its massive propellers sounded like a scream of tortured iron.
CLANG. CLANG. CLANG.
The docking bells rang out, a heavy, discordant sound that echoed through the empty warehouses. Solar didn't move. He waited until the massive steel hull ground against the pier, sending a shower of sparks into the dark water.
"The Manifest, Elias," Solar whispered. "Now."
Elias handed him a damp stack of papers. Solar didn't need a light. He could feel the ink. He could smell the desperation on the parchment. "Souls, Elias. That's what's in the hold. Not just 'migrant labor'. Not just 'contracted workers'. Souls. Debt-slaves who traded their sunlight for a chance to breathe the smog of Aethelgard. And according to this... three are missing."
"The crossing was rough, sir," Elias stammered, his teeth chattering. "The life-support in Steerage B... it failed. They say the air turned to water."
Solar turned, his eyes two shards of frozen slate. He grabbed Elias by the collar, pulling the boy close until their foreheads touched. Solar's breath was cold. Sterile. "Failed? Air doesn't 'fail', Elias. It's withheld. If they died, it's because the Captain decided their oxygen was worth more than their lives. He sold my assets to the atmosphere. That's theft."
He pushed the boy back and walked toward the gangplank. The Captain was waiting there—a bloated man with skin like wet parchment and eyes that darted everywhere except at Solar.
"Solar," the Captain grunted. He tried to smile, but it looked like a wound opening. "The sea was a bitch this time. Lost a few 'units'. Nothing to worry about."
THWACK.
Solar didn't use his fist. He used the heavy, iron-bound ledger he always carried. He caught the Captain across the jaw with the metal corner. The man dropped to the wet wood of the pier, clutching his face.
"A 'unit' is an entry in my book, Captain," Solar said, his voice dropping to a terrifying, quiet hiss. "And my book is never wrong. You owe me three lives. Three contracts. Three hundred years of potential interest. Do you have that in your pocket? Or should I start harvesting the organs of your crew to make up the difference?"
The Captain started to crawl away, his boots slipping on the fish-scales and grease. "Solar, please! The filters... they were old! I'll pay! I'll double the next shipment!"
"There won't be a next shipment," Solar whispered, stepping on the man's hand. CRUNCH. Solar heard the small bones snap. He didn't flinch. "The Harbour of Souls has a very simple rule: you enter with a debt, and you leave when I say so. You? You're staying. Indefinitely."
He turned to the guards waiting in the shadows. "Liquidate the ship. Every crate. Every lung. Every drop of fuel. The Captain stays on the pier. Tie him to the pilings. Let the tide decide what his interest rate is tonight."
Solar walked back toward the city, the fog swallowing the screams behind him. He didn't look back. He never did.
CLINK. CLINK.
He flipped his gold sovereign. The metal felt warm against his cold palm. The harbour was quiet again, save for the lapping of the black water. Another audit. Another soul trapped in the port with no exit.
He poured a glass of water from a flask. It was clear. Perfectly filtered. Cold. Somewhere in the hold of that ship, a child was gasping for air that didn't exist. Solar drank it slowly, feeling the chill settle in his chest. He didn't feel a thing. No pity. No regret. Just the weight of the gold.
The interest never sleeps. And in the Harbour of Souls, the debt is eternal.
