"Spread to the third marking line," Christian said, his fingers pointing to the pale scratch in the sand near Ryan’s left heel. "Do not step past the grid intersection, no matter how close the vanguard gets."Ryan adjusted his grip on his iron shortsword, his palm sweating against the leather wrap. "Christian, there are sixty of them. The official roster listed a single platoon of thirty instructors. Why did the gate release a double deployment?""Because the Senior Elders are desperate to fix their ledger before the audit closes," Christian replied, his voice a flat, level murmur against the rising noise of the crowd. He did not look up at the high glass windows where the academy administrators sat. "They believe that by doubling the physical mass on the eastern flank, they can crush our positioning before we find an exit vector. They are trying to overwrite a structural error with raw numbers."Across the sand, the heavy iron boots of the Academy Guard instructors hit the ground in

The internal counter in Christian’s mind hit zero, and the connection snapped.The sixty heavy iron spears locked into the sand did not explode. Instead, the amber light glowing along the metal shafts turned instantly black. The kinetic energy the Academy Guard instructors had poured into their enchantment had nowhere left to go. The library tower’s reservoir was full, the valve had closed, and the remaining force bounced straight backward through the iron weapons like a physical recoil.A sharp, metallic cracking sound rippled down the sixty-man line.Captain Vane let out a choked grunt as the gravitational feedback slammed into his chest plate. The heavy steel armor became a trap, multiplying the weight of his gear by four and dragging his knees into the sand. Around him, the other fifty-nine instructors dropped simultaneously, their shields clattering against the stone. They weren't bleeding, but their muscles were completely paralyzed by the sudden vacuum of mana in their channels

The temperature dropped by exactly one degree for every twelve stone steps they descended into the dark. Christian kept his right hand pressed flat against the rough obsidian wall to maintain his balance, using the sharp friction of the cold stone to keep his mind from slipping into unconsciousness. The dark gray blocks of the central library tower had long since given way to raw, unhewn bedrock, covered in a thick layer of white frost that didn't melt under the blue glow of Lyra's lantern.His internal clock was running a strict countdown. Thirty-eight minutes. That was the absolute limit his current physical container could endure before the micro-fractures in his primary mana pathways became permanent structural defects. Every breath he took felt like inhaling cold iron filings, the sharp pain spreading from his chest down to his fingertips. The unrefined mana core in his lower belly was spinning out of control, creating a violent friction that threatened to dissolve his meridian l

Six iron warships hung in the sky like execution blades.Their massive hulls cast long shadows over the academy, turning midday into artificial twilight. The royal standard—a golden sun split by a black sword—flew from the lead ship's main mast.The Crown Prince had arrived.Down below, the student body stood frozen on their balconies. They knew those ships didn't move unless the empire was facing a rebellion.Christian sat at the small wooden desk in his D-Class quarters, fingers resting lightly on the plain table.His new core pulsed steadily in his lower abdomen, cold and heavy like a drop of mercury. The void inversion had changed him. He didn't just see the world anymore; he felt its physical parameters. He could feel the exact weight of every iron hull floating above the valley. He felt the displacement of air, the subtle pulling of gravity, and the precise coordinates of heavy boots approaching his cabin.Ryan burst through the doorway, his chest heaving. He had left his linen

The low rumble of steam vents faded as the six iron warships rose another hundred feet into the air.They didn't leave the valley. They anchored themselves above the high stone peaks, a permanent metal ceiling over the academy. The artificial twilight remained, stretching long, thin shadows across the dirt road of the ravine.Inside the cabin, the heavy air finally returned to normal.Ryan dropped to his knees, his hands pressing flat against the cold floorboards. His face was slick with sweat, his breathing loud and erratic. "We're alive. I thought he was going to drop his hand. I really thought he was going to kill every single one of us.""The Prince calculates risk," Christian said, sitting back down at the desk. He picked up his bone stylus. "Killing us gives him a clean ledger, but it leaves his northern army without bread. A king cannot fight a war with an empty stomach. The math didn't favor an execution."Lyra didn't sit down. She stood by the window, her eyes fixed on the sh
