The transition from the roaring chaos of the Drowning Pool to the absolute, suffocating silence of the hollow glacier was like stepping into a tomb.

The *Ember* limped through the narrow, ice-slicked channel, her steam engine idling in a low, rhythmic wheeze that sounded dangerously like a dying breath. Every revolution of the propeller vibrated through the dented copper hull plates, sending a dull, shuddering ache directly up the wooden tiller and into Cormac Reed’s left arm. His right arm, wrapped in a rigid, mud-crusted bandage that had frozen into a heavy, stone-like cast, hung uselessly at his side. The raw blisters beneath the wrapping screamed in protest against the sub-zero dampness, but Cormac kept his jaw clenched, his eyes fixed on the pale-blue light reflecting off the glacier walls ahead.

Base Camp One was nothing more than a skeletal timber cabin built into a natural cavern of hollowed ice, a relic of his father Kieran’s early surveys decades ago. The structure hung over a sluggish side-pool of the frozen river, its pine beams black with age and coated in a thick, glittering rime of frost.

"Devin, Colm’s rope!" Cormac commanded, his voice a gravelly rasp that barely carried through the freezing air. "Get him onto the shelf. Garrick, kill the boiler before the condensation freezes the pistons solid."

From the bow, Devin scrambled onto the slippery basalt shelf, his hands shaking violently as he threw the heavy, oil-soaked mooring ropes around the rusted iron pitons. The ropes, treated with volcanic wax to repel the freezing water, thudded against the stone with a dull, heavy sound.

On the deck, Dr. Fiona Glenn was already working in a frenzy of clinical desperation. She and Toby Miller had wrapped Colm in three layers of dry caribou-skin insulation pads, but the young deckhand was shivering so violently that his teeth clicked together like dry bones. His face was a sickly, translucent white, his lips a dark shade of bruised purple.

"He’s slipping, Cormac," Fiona said, her breath coming in thick, rapid plumes of white steam. "The cold-shock has seized his chest. If we don't get his core temperature up, his heart will stop before the lanterns burn out."

"Move him into the cabin," Cormac ordered, his left hand gripping the wooden gunwale to steady himself as he stepped off the boat. "Liam, get the copper warming pans ready. Use the remaining dry driftwood to build a localized fire in the stone hearth. Maura, audit the cargo. I want a strict tally of what we lost."

The crew moved with sluggish, mechanical movements, their bodies stiffened by the bone-chilling cold. They carried Colm into the drafty cabin, where the air was so cold it stung the lungs with every breath.

Cormac stood in the center of the dark room, watching Fiona work. She had opened her silver-plated case of surgical tools and was rapidly mixing a thick, gray paste in a stone mortar. The smell of sulfur and wet clay filled the tight space—warm Geothermal Mud, scooped from the hot spring vents near the chasm mouth before they descended.

With practiced, steady hands, Fiona applied the warm clay directly to Colm’s chest, spreading it thick over his shivering ribs. Almost instantly, a thin wisp of steam rose from his skin as the mineral-rich mud began to draw out the deep tissue chill, forcing the sluggish blood back to his vital organs. Colm let out a low, rattling groan, his eyes rolling back as his body fought the agonizing transition from freezing numbness to burning warmth.

"It will save his fingers," Fiona muttered, her silver-streaked hair falling loose from her hood as she turned her sharp eyes to Cormac. "But what about you? Let me see that hand."

Cormac stepped back, tucking his rigid right arm deeper into his caribou-skin coat. "Treat the boy first. I can still walk."

"You won't be walking anywhere if gangrene takes the bone, Reed," she snapped, her clinical bluntness cutting through the quiet cabin. "The mud on your bandage is cracked and black with frozen blood. The nerves in those fingers are already dying. If you keep pushing that tiller with a dead hand, you’ll lose the arm before we reach the Fjord."

"We have three days of river left before the Fjord, Fiona," Cormac said quietly. "And right now, we don't even know if we have enough oil to keep the lanterns lit for one."

As if on cue, Maura Lynch entered the cabin, her keys jingling at her waist with a cold, metallic ring. Her sharp-featured face was grimmer than usual, her fingers clutching a dry piece of charcoal and a grease-stained ledger.

"The audit is done," Maura said, her voice flat, devoid of any comfort. "Six canisters of refined Old-World Kerosene are gone. Pulverized by the glacier block or swallowed by the pool. We have three left in the primary lockers. At our current burn rate, keeping the Hearth-Lantern’s heater active to prevent the oil from freezing will give us exactly thirty-six hours of light. If we use the secondary lanterns, we cut that in half."

A heavy, suffocating silence fell over the cabin. Toby Miller, who had been huddling near the cold hearth, looked up, his brass-rimmed spectacles fogged with rime.

"Thirty-six hours," Toby whispered, his voice trembling. "But the coordinates in Kieran's journal... the ones Alistair translated... they show the first geothermal vent is at least forty-eight hours downstream. If the light fails before we reach it, we'll be drifting blind in the dark. We won't even see the ice-spears before they shear the hull."

"We ration," Cormac said, his tone leaving no room for argument. "Maura, cut the daily rations of Salted Lake Trout to half. We use the Hearth-Lantern only when we are moving through the rapids. When we are moored, we rely on the coal hand-warmers and the natural light of the bioluminescent algae walls. We don't waste a single drop of refined oil."

"And what about the crew?" Silas Vance’s voice cut through the shadows from the cabin doorway.

The bitter second-in-command stood with his hands tucked into his fine, fur-trimmed coat, his cold gray eyes scanning the room with a calculating intensity. His manicured beard was white with frost-rime, but his face was flush with a nervous, defensive heat.

"The deckhands are already whispering, Cormac," Silas said, his voice dripping with a soft, venomous concern. "They saw the raft split. They saw Colm almost drown. They’re cold, they’re hungry, and they’re starting to remember your last expedition. They’re starting to think the Reed name is a curse that brings nothing but frozen graves."

"The raft didn't split because of a curse, Silas," Cormac said, turning slowly to face him. He stepped forward, his rugged, weather-bitten face inches from the navigator’s. The jagged frostbite scar across his right jawline tightened. "Seasoned pine doesn't shear cleanly along the grain in calm water. It takes a tool to make a cut like that."

Silas didn't flinch, but his fingers twitched slightly near his coat pocket, where his private copper fuel flask was concealed. "Are you accusing the ice of malice, Cormac? Or are you just looking for someone to blame for your own failed leadership?"

"I'm looking for the truth," Cormac said, his voice dropping to a low, dangerous whisper. "And I usually find it in the dark."

Before Silas could answer, Aidan, the young scribe, caught Cormac’s eye from the far corner of the cabin. The boy was pale, his ink-stained fingers trembling as he gave a subtle, almost imperceptible nod toward the dark passage leading back to the docks.

Cormac turned away from Silas without another word, stepping out of the cabin and into the freezing, blue-shadowed corridor of the hollow glacier. Aidan followed him quietly, his boots making no sound on the hard-packed ice.

Once they were deep in the shadows, away from the prying eyes of the crew, Aidan reached into his heavy wool coat. His hands were shaking so violently that he almost dropped the object he was holding.

"I... I found it, Cormac," Aidan whispered, his voice cracking with terror. "In the bilge of the *Ember*, wedged right under the secondary frame where the tow line was anchored. The water was already freezing around it, but the copper didn't rust."

He handed Cormac a heavy, specialized tool. It was a custom copper auger, its handle wrapped in a cross-hatched leather grip. The tip of the drill was dark with a mixture of grease and fresh oak shavings.

Cormac held the tool in his left hand, turning it over in the weak, blue light of the ice walls. His eyes narrowed as he recognized the distinct, three-ring weld on the brass collar.

"This belongs to the Oakhaven harbor guild," Cormac muttered, his voice cold as the ice beneath his boots. "Only three men had access to this style of tool before we cast off."

"It’s Gideon’s," Aidan whispered, his eyes wide with a desperate fear. "I checked his ledger records. He signed out this exact auger from the harbor workshop two days before launch. Cormac... the holes in the secondary raft weren't accidental. Someone drilled them from the inside, below the waterline, before we ever left the docks. They wanted the raft to sink. They wanted us to lose the fuel."

Cormac’s mind raced, the pieces of the puzzle falling into place with a terrifying, logical precision. The silent drilling. Gideon’s nervous glances toward Silas during the rescue. Silas’s immediate, frantic demand to cut the tow line and abandon the fuel canisters. It wasn't just survival panic; it was a deliberate, coordinated sabotage to force the expedition to turn back to the surface.

"Who else knows about this, Aidan?" Cormac asked, his voice low and steady.

"No one," the scribe said quickly. "I came straight to you. But... Silas has been talking to the deckhands. He’s telling them that the engine is failing, that we don't have enough coal to fight the lower currents, and that we should turn back before we reach the Silent Fjord. If they find out someone is actively destroying our gear... there will be a mutiny, Cormac. They’ll seize the boat and run."

"We don't tell them," Cormac said, his left hand locking around the copper handle of the auger. "Not yet."

"But Gideon—"

"Gideon is a tool, Aidan. If we arrest him now, Silas will panic. He’ll trigger the mutiny before we can secure the remaining fuel or find a safe path through the rapids ahead. We are three days from the Silt-Walker hunting grounds, and we have no alternative oil. We need Gideon to think he succeeded, and we need Silas to think we are still blind."

Cormac tucked the auger into his inner coat pocket, adjacent to Kieran's encrypted journal. "Go back to your ledger. Keep recording the fuel consumption, but keep a separate, private tally of every hour Silas spends near the cargo hold. And tell Bredan to place a secret guard on the remaining kerosene. If anyone goes near those lockers without my direct written order, they are to be detained silently."

"I understand," Aidan said, his face still pale but his gaze turning resolute as he nodded and slipped back toward the cabin.

Cormac stood alone in the dark corridor, the cold of the glacier wall seeping through his heavy caribou-skin suit. Every breath was a struggle against the dull, burning ache in his chest and his dead right hand. He had promised his sister Nora that he would bring the warmth back to Oakhaven, that he would make the Hearth burn again. But now, the greatest threat wasn't the freezing river or the blind predators of the deep.

It was the rot inside his own crew.

He walked back to the entrance of the cabin, his boots crunching softly on the ice. Through the half-open timber door, he could hear the low, hushed voices of the deckhands.

Silas was standing near the weak, blue-burning Hearth-Lantern, his face illuminated by the flickering, cold light. The shadow of his sharp jawline stretched long and distorted across the frost-covered wall, looking like a dark, predatory beast waiting to strike.

"How many more of us have to freeze before we admit the truth?" Silas was whispering to the huddling men, his voice smooth, carrying a false, sympathetic warmth. "Cormac’s brother died in the dark. Now we’ve lost half our oil, and Colm is barely breathing. We are following a dead man’s ghost down a river that has no end. If we don't turn back now, we'll all be nothing but frozen statues in this glacier before the week is out."

The deckhands muttered in agreement, their hollow eyes staring into the weak blue flame, the seeds of doubt and terror planting deep in their cold-ravaged minds.

Cormac stood in the shadows, his hand resting on the heavy copper tool in his pocket, watching the silent mutiny build in the dark.
