The iron lift of the Deep Veins was not a machine designed for comfort; it was a vertical iron cage, a suspended gallows that groaned under the weight of its own antiquity. As the heavy, rusted gates hissed shut with a finality that echoed like a tomb door, Renji felt the first true wave of vertigo.
The cage did not begin its ascent with a smooth pull. It lurched. The massive, Aether-driven chains overhead snapped taut with a sound like a thunderclap, and the floor surged upward, forcing Renji to his knees. Beside him, Toby let out a muffled whimper, clutching at the iron bars until his knuckles turned as white as the marble below. Hana, the nurse, leaned against the back of the cage, her eyes closed, her breath coming in shallow, rhythmic rasps that betrayed the early stages of mana-lung.
Lyra Thorne remained standing. She didn't hold the bars. She didn't brace herself. She stood at the center of the cage, her Wolfsteel boots seemingly magnetized to the floor, her amber eyes fixed on the darkening shaft above. She looked like a statue of silver and shadow, immune to the violent vibrations that threatened to rattle Renji's teeth out of his skull.
"Don't look down, Sato," Lyra said, her voice cutting through the mechanical screech of the ascent. "The depth is a psychological poison. If you look at where you were, you'll never reach where you're going."
Renji, of course, looked down.
Through the gaps in the iron grating of the floor, the Deep Veins were shrinking into a miniature diorama of hell. The massive quartz pillars, which had felt like mountains only minutes ago, were now mere needles of blue light. The hundreds of workers were reduced to flickering specks of grey, their rhythmic pickaxe strikes no longer audible, replaced by the howling wind of the vertical shaft. The violet mud was now just a smudge of bruised color on the floor of a world that seemed to have no bottom.
As they climbed, the temperature began to shift. The stifling, humid heat of the subterranean pits—thick with the scent of wet stone and human sweat—was being stripped away by a rising, frigid draft.
"Three miles," Lyra said, her voice a low vibration that seemed to harmonize with the humming mana-lamps in the lift. "The Architects built the Deep Veins to be the roots of the world. But roots aren't meant for breathing. As we pass the second mile, the atmospheric pressure will drop. Your blood will feel like it's boiling. Your brand will react to the thinning Aether. If you lose consciousness, you die. The System doesn't have a safety net for the weak-willed."
Renji felt it then—the first pang of the 'Pressure-Sickness.' It started as a dull throb behind his eyes, a rhythmic pulsing that synchronized with the silver star in his palm. The brand began to glow again, not with the violent flare of the explosion, but with a steady, haunting luminescence. It was as if the star were a compass needle, and the surface of the world was its North.

"My head..." Toby groaned, clutching his temples. "Renji, it feels like my ears are going to pop out of my head."
Renji reached out, his hand trembling as he placed it on Toby's shoulder. "Just breathe, Toby. Slow breaths. Like we're on the train. Just one more stop."
"There are no more stops, Sato," Lyra remarked, her gaze finally shifting to him. She watched the way his brand pulsed through the fabric of his ruined suit. "You are attempting to comfort a soul that is already being processed by the world. It's a waste of energy. Use that Aetheric resonance to stabilize your own heart. If you don't, the transition will burst your capillaries before we hit the crust."
Renji ignored her, focusing all his will on Toby. But as they crested the second mile, the "Boiling" began.
The air in the shaft became unnaturally thin. Every breath Renji took felt like inhaling cold needles. The silver light in his palm suddenly surged, tracing lines of white fire up his arm, following the meridian of his nerves. He felt a terrifying pressure building in his chest, as if a balloon were being inflated inside his ribcage.
"The transition!" Lyra commanded, her voice suddenly sharp. She stepped forward, grabbing Renji by the lapels of his suit and slamming him against the iron bars. "Sato! Don't fight the pressure! Visualize the Aether! It isn't air—it's a fluid. Let it into your lungs. If you try to breathe like a human, you will drown on the surface!"
Renji's vision began to grey out at the edges. He saw the world through a tunnel. He saw Lyra's face—not the mask of the Captain, but the face of a woman who was seeing a valuable tool about to shatter.
He stopped fighting. He forced his mouth open and, instead of gasping for air, he reached out with his mind toward the silver star in his palm. He pulled the light inward.
The sensation was transformative. It felt like drinking liquid starlight. The pressure in his chest didn't vanish; it equalized. The cold needles in his lungs turned into a soothing, electric warmth. His vision snapped back into focus, sharper than it had ever been in Tokyo. He could see the microscopic fissures in the iron bars, the individual threads of Lyra's silver cloak, and the tiny, glowing runes etched into the wolfsteel of her armor.

Lyra released him, her eyes narrowing as she watched the silver light recede into his skin. "Better. You've taken your first breath of the new world. Most Earth-born take weeks to trigger that reflex. Many die before the first mile is done."
The lift hit a final, violent lurch, and the mechanical screeching reached a crescendo. Then, silence.
The heavy iron gates hissed open, and Renji was blinded.
It wasn't a flash; it was a deluge. After months of the monochromatic blue and violet of the pits, the sheer spectrum of the surface was an assault. He shielded his eyes, his heart hammering against his ribs.
As his pupils finally adjusted, Renji stepped out onto a platform of white, polished marble that seemed to hang in the sky itself.
He was standing on the Great Wall of Newhaven.
It was a structure of impossible scale, a rampart of stone and Adamantine that stretched to the horizon in both directions, curving with the arc of the planet. It was wide enough to house entire cities within its battlements. Above them, the sky was not the bruised purple of the cavern, but a deep, crystalline sapphire.
And then he saw them.
Two suns hung in the firmament. One was a massive, roaring furnace of brilliant gold that cast long, sharp shadows across the world. The other was smaller, a hauntingly beautiful orb of ethereal rose-pink that softened the edges of the horizon. They didn't move like the sun back home; they seemed to be locked in a slow, celestial dance, their light intermingling to create a sky of shifting, iridescent colors.
"The Gold and the Rose," Lyra said, standing beside him, her silver cloak snapping in a wind that smelled of pine, snow, and something ancient. "One for the body, one for the soul. They are the Architects' eyes. They watch everything we do, Sato. They see the crimes we commit in the name of survival."
Renji looked down from the Wall.
To the South, the world was a paradise. A lush valley of silver-leafed trees swayed in the wind, their branches heavy with fruit that glowed like embers. Stone cottages with thatched roofs were nestled beside winding rivers of sapphire water. It looked like a painting from a storybook, a world of peace and plenty.
But then he looked North.
The North was a scar. Beyond the Wall, the land was a jagged wasteland of obsidian spires and black, smokeless fire. The clouds there were thick and sluggish, looking like bruised flesh, and beneath them, things moved—massive, multi-limbed silhouettes that defied the laws of biology. A dark, oily fog clung to the ground, and even from this height, Renji could feel the "Static" of the Corruption Tundra, a low-frequency hum that made his brand throb with a warning heat.
"That is the Abyss," Lyra said, her hand resting on the hilt of her sword. "And this Wall is the only thing keeping it from swallowing the valley. The Iron Covenant maintains the barrier. The Silverwind Collective studies the rot. And the Vanguard... we are the ones who go out there to die so the valley stays green."
She turned away from the vista, her expression returning to its habitual coldness. "Toby, Hana, Darius—you will be taken to the Processing Hub. Sato, you are coming with me to the North Tower. Commander Draven is waiting to see the 'miracle' I pulled out of the mud."
Renji looked at Toby, who was staring at the two suns with tears streaming down his face. "Go with them, Toby. I'll find you soon. I promise."
"Promises are heavy things in Aetheria, Sato," Lyra remarked as she began to walk down the marble rampart. "Don't make them if you aren't prepared to pay for them in blood."
As Renji followed her, his ruined dress shoes clicking against the pristine white stone, he looked back at the North. He realized then that the five years he had been given weren't a gift. They were a countd
