Months had bled into a singular, agonizing cycle of grey dust and rhythmic violence. In the lightless throat of Sector Four, the passage of time was no longer measured by the rising sun of Caelum , but by the layer of grime that thickened on Elian's skin and the increasing sharpness of his collarbones.
Yet, for the small unit known as the Crows, the atmosphere had shifted. The paralyzing dread that had gripped them during the first week had settled into a grim, mechanical competence. Even the cold shrills that had once raced down Elian's spine—the phantom sensation of being watched by something or someone—had gone silent. The crevice opened by the vault-slip remained a dark, yawning mouth in the wall, but nothing had emerged. The mountain, it seemed, had gone back to sleep.
"Rhythm, Baraq . Don't fight the stone, let the Siphon find the fault," Elian murmured, his voice sounding older than his twelve years.
He didn't need to look up to know the other slave units were watching them. Over the last few days, the Crows had transformed from a group of dying "runts" into one of the most efficient mining team in the sector. While other units saw men collapse daily from the Siphon-exhaustion, Elian's group returned to the lift every evening with a basket brimming with shards.
It wasn't magic—not yet. It was Elian's presence of mind. He had spent the months analyzing the rock faces not as obstacles, but as structural puzzles. He had mapped the thermal vents and the way the Aether-dust settled, identifying the "Soft-Veins" that ran parallel to the reinforced Hard-Cap. By his direction, they were mining about same amount the yield but with half the physical exertion. The envious gazes of other slaves followed them like daggers in the dark, but Elian ignored them. He was busy building a map of a world he had only just joined.
During the long, low-humming hours of shifts, Elian had began to dig for a different kind of ore: information.
"Talin," Elian said, his pickaxe striking a rhythmic clink against a cooling vein. "The guards talk about Aura-Knights and Mana-weavers like they're gods. If they all come from Aether, why are we down here digging it up for them?"
Talin paused, wiping a mixture of sweat and obsidian dust from his brow. He looked at Elian with a sort of confusion. "Because Aether is the breath of the world, boy. It's the spark. But us... well, most of us are born like leaky buckets. We can't hold it."
He leaned on his pickaxe, his voice dropping to a gravelly low. "Aether has two faces. Aura is the physical side—it's the Aether made heavy, woven into the muscles and the blood. That's the path of the Knight. They use it to turn their skin to iron and their swords into pillars of light. Then there's Mana, the spiritual side. That's for the Mages. They refine the Aether in their hearts to command the elements. Both come from the same well, but it takes a 'Core' or a 'Circuit' to use it. Without those, you're nothing or worst a sapper, letting a piece of iron drink your life to break a rock."
Elian processed this, his Kaito-brain comparing Talin's words to the fragmented, hazy memories of the original Elian. In his mind, he saw flashes of a white-haired man—his father—moving with a speed that defied physics. That was Aura. He remembered a woman's hand glowing with a soft, blue light . That was Mana.
"And the crystals we find?" Elian asked, gesturing to the flickering blue shards in their basket. "Are they all the same?"
Talin spat into the dust. "Hardly. What we find here in the Outskirts is Low-Grade. It's dirty, flickering, and barely holds a charge. It's the scrap used to power streetlamps and slave-tools. Mid-Grade crystals are denser—they glow like a captured summer sky and hold ten times the energy. Those are found deeper in the Lawless Zone, where the Aether-pressure is high enough to crush a normal man's lungs. And High-Grade... well, those are the 'Hearts.' They're found in the Inner Circles, near the roots of lawless zone. They don't just glow; they pulse like a living heart."
Talin's eyes drifted to the dark tunnel behind them. "We're just scratching the skin of the world here, boy. The deeper you go, the more the world tries to kill you for being there."
"Is that why the beasts are there?" Elian asked.
Talin nodded grimly. "The beasts are just Aether given claws. They follow the Tiers, lad. From the Feral Tier 1s that are just oversized wolves, all the way up. You get to Tier 3, the Mutated, and they start breathing fire. By Tier 4, the Terrors, they grow an Essence Stone in their chest—a Core of their own. That's the threshold. Anything higher, like a Tier 6 Behemoth or a Tier 7 Ancient, and you aren't looking at an animal anymore. You're looking at a walking disaster."
Elian listened intently as Talin described the Mystics of Tier 8, who could speak and take humanoid forms, and the legendary God-Eaters of Tier 9, whose very existence was said to rival the World itself.
As Talin spoke, Elian's silver-grey eyes didn't show fear; they showed calculation. He was comparing the "God-Eaters" to the corporate titans of his past life—entities so powerful they changed the landscape just by existing. But here, the power wasn't in stocks or contracts; it was in the Aether.
"We are in the Outskirts," Elian repeated, his voice quiet. "Which means the Tiers here shouldn't exceed Tier 2 or 3."
"Usually," Talin grunted, turning back to the wall. "But the mountain is restless, Elian. When the veins bleed, things move from the Deep to the Shallow. Keep your eyes open, and your pickaxe ready."
The conversation ended as the heavy, humid silence of the mine settled over them once more. Elian raised his tool, but his gaze remained fixed on the pitch-black tunnels stretching into the unknown. The shivers had stopped, but the cold realization in his gut was just beginning to grow.
