The transition wasn't a clean break; it was a slow, agonizing leak.
Leaving the Tower felt like being a deep-sea diver rising too quickly toward the surface. Within the Tower's walls, the mana was thick, heavy, and structured—a high-pressure atmosphere that had been crushing my "unstable" pathways for weeks. But as the iron-shod wheels of the Soot-Eater transport rattled across the bridge and into the shadow of the outer peaks, that pressure vanished.
In any other world, this would be a relief. For me, it was a biological emergency.
My abdominal core was currently a pressurized tank filled with supercritical mana. Inside the Tower, the high external pressure had helped hold that energy in place. Now, out in the Grey Barrens, the "air" was thin and empty. My internals were pushing out against a vacuum. I felt like a soda bottle that had been shaken vigorously and was now being opened in the middle of a desert.
"Easy," I hissed, leaning against the wooden slats of the cart. I closed my eyes and sank into the Library.
The Library hummed, though the sound was fainter out here. The "Speed of Thought" kicked in, allowing me to visualize my internal state.
The "Mana Air Pressure" in the Barrens was near zero. My core, currently sitting at roughly 1,100 units of pressure, was straining against my ribs. I had to manually tighten the "valves" of my mana-veins, using the Analysis function to pinpoint the exact spots where the energy was trying to leak through my skin.
If I let the pressure drop too fast, I'd undergo what Earth divers call "The Bends"—my mana would bubble in my blood, shredding my nervous system from the inside out. I had to descend slowly, even as the cart bumped along the jagged, ash-covered road.
"You alright, Hero?" Akhtar's voice was low, cutting through the rattle of the transport. He was riding a gaunt, mana-depleted horse beside the cart, looking every bit as miserable as I felt. To him, the Barrens were a tomb. His own mana-circuits were flickering, struggling to find enough ambient energy to keep his basic protective spells active.
"I'm... adjusting," I managed to say.
"Don't adjust too much," he muttered, eyeing the horizon. "The Barrens aren't just empty. They're hungry. The things that live out here don't have a steady diet of Tower-mana. They see a mage as a walking feast."
I nodded, pretending to be weak, but my mind was already scanning the horizon. This "hunger" was exactly why I was here.
The "nominal mission" was a stroke of bureaucratic genius. The Tower needed Resonance Salts—crystalline mineral deposits that formed where the world's ley lines had frayed and bled into the soil. These salts were the only things that could stabilize the "clouding" lenses of the portal device—the very clouding I was currently inducing with my nightly thermal-cycling sabotage.
The Soot-Eaters were the bottom rung of the Tower's ladder. They were "duds," failed apprentices, or criminals serving a sentence. They were sent into the ash-fields with brushes, filters, and heavy lead-lined buckets to scrape the salt from the underside of blackened rocks.
When we reached the "Extraction Camp"—a collection of sun-bleached tents huddled in a ravine—I was handed my gear.
A wide-brimmed hat to keep the caustic ash out of my eyes.
A filter mask made of cheap, mana-treated silk.
A heavy iron scraper.
The camp supervisor, a scarred man who looked like he'd been chewed on by a rock-worm, didn't even look at me. "Akhtar says you're here for 'acclimatization.' I don't care if you're the King of Earth. You don't scrape, you don't eat. The quota is three pounds of salt a day. Don't touch the blue crystals with your bare hands unless you want your skin to turn into glass."
He gestured toward the vast, grey expanse of the Barrens. "Go. Stay within the bell-radius. If the camp bell rings, it means a storm is coming."
As the other Soot-Eaters shuffled off toward the salt-flats, I headed in the opposite direction—toward the jagged foothills where the Earth Behemoths were rumored to roam.
Akhtar watched me go, his hand resting on the hilt of his sword. He was supposed to be my guard, but the low-mana environment was already making him sluggish. He stayed near the camp's central ward-stone, the only place where a mage could feel "normal." He thought I was just looking for a quiet place to breathe.
As soon as I was out of sight, I dropped the "sickly hero" act. I moved with a predatory efficiency, my boots crunching on the volcanic soot.
"Library: Initiate Environmental Scan," I commanded.
This was a skill i invented by combining the analysis, the photographic memory and the speed of thought functions.
By feeding the surroundings too the analysis quickly , I could let the Library build a model of the area.
The Stone in my mind hummed, drawing a trickle of mana from my core to power the calculation. Even in this "empty" zone, the Stone was greedy. It needed a constant intake to maintain the Library, and since there was no mana in the air, it was drinking directly from my pressurized reservoir.
I could see the "Failure-Tolerant" path the Architect had laid out for me. My left shoulder—the Dead Zone—was acting as a perfect ground. Whenever my internal pressure became too much to handle, I pushed the excess energy into the obsidian. It didn't store it; it annihilated it, acting as a "Safety Valve" that kept my heart from exploding in the low-pressure environment.
"The Dead Zone isn't a handicap out here," I realized, looking at the black graft. "It's my regulator."
I spent the first few hours actually scraping salt—mostly to keep up appearances and to test the "Analysis" function on the local geology. But my eyes were on the "fault lines" in the earth.
According to the Bestiary I'd scanned, the Earth Behemoth wasn't a biological creature in the way we think of animals. It was a "Litho-Elemental"—a living pile of mana-saturated rock and carbon. It was slow, nearly blind, and incredibly defensive.
A Tier-3 mage would try to blast it with high-pressure water or lightning. But I didn't have the mana to spare, and my magic was still too "noisy." I had to hunt like an engineer.
I found a set of tracks near a sulphur spring. They were massive—six-toed indentations pressed deep into the hardened ash. Each footprint was the size of a dinner table.
"Analysis: Calculate mass and gait," I whispered.
Subject: Earth Behemoth (Juvenile) Estimated Mass: 4,200 kg Armor Composition: Sedimentary rock reinforced by mana-latticed carbon. Vulnerability: The 'Core-Stem' located at the junction of the third and fourth vertebrae.
The Behemoth was a walking fortress, but it had a fatal flaw: Inertia. Because it was so heavy and moved on such thick, rigid legs, it couldn't change direction quickly. On Earth, we use this against heavy machinery all the time. If you can tip a tractor past its center of gravity, it doesn't matter how much horsepower the engine has—it's not getting back up.
I didn't need a sword. I needed a Lever.
I spent the next four hours preparing the "Kill Zone" in a narrow canyon. I used my iron Soot-Eater scraper to dig into the base of a towering, precariously balanced rock spire.
I wasn't digging a hole; I was creating a Structural Failure Point. I used the "Analysis" function to find the exact "stress-line" of the stone. I packed a small, highly compressed "bead" of my own mana into the crack—a primitive thermal detonator.
If the Behemoth walked past this spire, the vibration of its footsteps would trigger the mana-bead. The expansion of the heat would snap the remaining "tether" of the rock, and four tons of granite would come down like a guillotine.
But I needed one more thing. I needed the Anchor.
The Architect's plan required the Earth Core to be used as a structural brace for my spine. To do that, I had to harvest the core while it was still "warm"—while the mana-lattice was still active and flexible. If I waited too long after the kill, the core would crystallize and become useless for "growing" into my bones.
"This is going to hurt," I muttered, looking at my left shoulder.
I began to route a thin, needle-like stream of mana from my core, through the "Bypass" pathways I'd been building, and into my fingertips. I was creating a "Thermal Lance"—not a spell, but a focused, high-pressure jet of energy that could cut through rock. It was incredibly inefficient, but it was the only way to get through the Behemoth's armor once it was pinned.
As the sun began to dip behind the jagged peaks of the Tower, the ground began to tremble.
It wasn't a fast vibration. It was a deep, rhythmic thump that rattled the salt-bucket at my feet. The Behemoth was coming. It smelled the "leak" of mana I had intentionally left at the mouth of the canyon—a trail of "bread crumbs" made of my own supercritical fluid.
I ducked behind a ridge, my heart hammering against my ribs. Out here, in the thin air of the Barrens, every breath felt like fire. My "Dead Zone" shoulder was cold, a black weight that reminded me I was asymmetric, broken, and dangerously unbalanced.
The creature rounded the corner. It was a nightmare of grey stone and moss, its eyes glowing with a faint, dim amber light. It moved with the slow, inevitable force of a landslide.
"Come on," I whispered, my hand hovering over the "trigger" bead in my mind. "Just three more steps."
The Behemoth paused. It sniffed the air, its massive head swinging toward my hiding spot. It sensed the "Supercritical" energy inside me. To a starving elemental in a low-mana wasteland, I wasn't a hero.
I was the most high-calorie meal it had ever seen.
