Gasping for breath, Clara leaned her back against the freezing metal wall of the corridor.
Air inside the sealed bypass was rapidly turning toxic, tasting of bitter copper and old rust.
Every single inhalation felt like pulling heated glass into her chest, burning her throat and making her ribs ache with a dull, throbbing pain.
Condensation from their breath had frozen onto the walls, forming a thin, treacherous glaze of black ice that mirrored their desperate faces.
Across from her, Jaxon knelt before a massive, circular brass hatch.
His fingers trembled against an intricate network of pneumatic tubes and pressurized valves.
A pale blue glyph flickered on his fingertips, but it sputtered and died as he shuddered, his magic failing to hold its shape in the thin air.
Frost magic required focus, and focus was a luxury his oxygen-starved brain could no longer afford.
"Focus," Jaxon muttered, his voice cracking into a dry, pathetic wheeze.
He slammed his palm against the bronze casing, desperate to spark his magic and force the locking mechanism to engage.
Sweat dripped from his chin, freezing into tiny, white beads on the icy floorboards before he could even wipe it away.
His chest rose and fell in frantic, shallow jerks, like a fish caught on a frozen riverbank.
Panic, raw and ugly, was unraveling his usual cold composure.
He was a creature of pure logic, but logic required oxygen to burn.
Without it, his brilliant mind was spinning in useless, terrifying circles, unable to grasp the complex mathematics of the lock.
His vision was beginning to fray at the edges, dark shadows creeping inward to swallow the brass hatch.
Clara watched him, her own head spinning as black spots danced across her vision.
Guilt gnawed at her stomach, heavier than the physical weight of the suffocating air.
Once again, her clumsy stumbling had dragged them into a deadly corner, sealing them in this airtight tomb.
Her family's harsh, mocking voices echoed in her mind, reminding her of her uselessness and the curse she carried.
They had always told her that she was a burden, a walking disaster who brought ruin to everyone around her.
"Let me help," Clara whispered, her voice barely a dry rasp in the quiet corridor.
She took a step forward, but her knees buckled, sending her sliding against the cold, frost-covered pipes.
"Stay back," Jaxon snapped, though the command lacked any of his usual biting arrogance.
His eyes were bloodshot, pupils dilated so wide they looked like pools of ink in his pale face.
He stared at the interlocking brass rings of the lock, trying to calculate the mathematical sequence of the pressure valves.
Three glass cylinders sat embedded in the center of the brass plate, each filled with a swirling, luminescent blue fluid.
Blue fluid surged violently, bubbling up to the red warning line at the top of the tube as Jaxon tapped it.
Warning chimes echoed through the narrow corridor, sounding like a slow, rhythmic death knell.
Pressure was rising in the wrong chambers, threatening to seal the hatch permanently and leave them to suffocate.
Jaxon's fingers slipped from the brass plate, his strength failing him as his body began to shut down.
Clara felt a cold dread settle in her stomach, sharper than the bite of the frost.
She remembered the day she had tried to help her father with the village well.
She had only wanted to pull up the heavy bucket, but her hand had slipped, breaking the wooden crank and dropping the bucket into the dark depths.
Her father's eyes had filled with a silent, cold fury that hurt worse than any physical blow.
"You are a plague, Clara," he had told her, his voice flat and dead. "Everything you touch breaks."
Now, she was doing it again.
She was going to kill Jaxon with her clumsy, useless existence.
He was going to die in this dark corridor because she couldn't even walk without tripping.
Desperation lent her a sudden, wild strength.
She had to do something, anything, to make things right and keep him from looking at her with that same cold hatred.
Slowly, she crept closer, her limbs feeling like lead weights.
Her knees scraped against the icy floor, but she ignored the pain, her eyes locked on the grimy brass pipes.
Dirt and icy grime coated the metalwork surrounding the lock, obscuring the tiny runes engraved upon them.
Perhaps if he could see the symbols clearly, his brilliant mind would find the answer.
"Maybe if they're clean, you can read them," Clara murmured, her voice thick with unshed tears.
Using the hem of her heavy woolen sleeve, she began to vigorously polish the metalwork.
Rubbing the tarnished brass gave her a singular purpose, a way to drown out the terrifying silence of their dying room.
She scrubbed at the dark frost, trying to make the ancient runes shine.
"Stop... touching things, Clara," Jaxon groaned, his vision tunneling into a narrow pinprick of light.
He reached out to pull her away, but his coordination was completely gone.
His hand slipped off her shoulder, his fingers limply scraping the cold metal before dropping to his side.
Rubbing harder, Clara leaned her entire weight into the pipe to scrub away a stubborn patch of black frost.
Her boot heel caught on a raised rivet in the floor.
With a startled cry, she pitched forward, losing her balance entirely.
Her hands flew out to catch herself, grabbing onto a thick, protruding brass lever.
Falling hard, her entire body weight pulled downward on the ancient metal handle.
*Snap.*
Heavy metal groaned as the lever broke off entirely at the base, leaving a jagged, hollow stump.
Clara tumbled onto the floor, clutching the broken piece of brass to her chest in absolute horror.
"I'm sorry!" she sobbed, tears freezing on her cheeks instantly. "Jaxon, I'm so sorry, I didn't mean to break it!"
A deafening hiss drowned out her apologies.
Pressurized air erupted from the broken stump with the force of a screaming gale.
Cold, sweet, pure oxygen rushed into the suffocating corridor, blasting over Clara's face like a physical wave.
Jaxon gasped, his chest expanding fully as his lungs drank in the fresh air.
He inhaled greedily, his eyes snapping open as color returned to his pale face.
Sudden rush of pure oxygen revived his failing senses in a matter of seconds, clearing the fog from his mind.
"You... you broke the auxiliary bypass," Jaxon muttered, staring at the rushing air in utter disbelief.
Pressure from a secondary tank was venting directly into the chamber, saving their lives.
But their relief was short-lived.
Heavy iron gears began to grind deep within the walls, triggered by the sudden, massive shift in pressure.
Floor plates beneath them shuddered violently, then swung downward like a trapdoor.
Gravity took hold of them instantly.
Clara screamed, her hands clawing at empty air as she plunged into the darkness.
Jaxon fell right beside her, his dark cloak billowing around him as they plummeted.
Cold wind rushed past Clara's ears, smelling of ancient soil and wet rot.
Plummeting through a vertical shaft for several terrifying seconds, they crashed through a thick canopy of frozen glass and brittle leaves.
They land in a forest of frozen, carnivorous vines that begin to twitch and reach for them, stimulated by the sudden rush of fresh oxygen.
