The walk from the city gates to the Tower felt like traversing a continent. Every step sent a jagged shockwave through my left shoulder, where the Cinder-Hound's teeth had turned my flesh into a blackened crater. My collarbone grated with a sickening, wet sound—a physical reminder that I was a scientist who had brought a ruler to a knife fight.
I was operating on the barest fumes of life. My mana pool sat at 2/100—a flicker so dim it was practically a rounding error. The only thing keeping my nervous system from total collapse was the needle-sharp thread of Pure Mana the Stone had left behind after processing the hound's soul.
As I crossed the threshold into the Tower, the sensation changed. The air here was pressurized with the ambient mana of a thousand mages. To a "Blank Slate" like me, it felt like walking into deep water.
The Stone didn't just take mana; it reacted to the environment. The higher the ambient mana pressure in the Tower, the more Work the Stone had to perform to keep the Library's internal state isolated. The Tower's density made the Stone hungry, and I was the only thing it could eat.
I was ten feet from my door when a shadow stretched across the stone floor.
"You're late, student."
Akhtar. He was leaning against my doorframe, his arms crossed. His eyes weren't just looking at me; they were glowing with Mana-Sight.
I froze. In a place like the Tower, Mana-Sight drowned in static. To a mage like Akhtar, the world was a collection of energetic flows and absences—not torn muscle or burned bone. It was a high-frequency scan that prioritized energetic anomalies over biological gore.
I had 2 units of mana. I couldn't hide the smell of sulfur or the blood on my cloak, but I could manipulate the Signal-to-Noise ratio. I channeled my remaining energy into a Surface Tension trick—stretching the pure mana across my skin to "smooth" the energetic ripples of my injury. I didn't try to look healthy; I tried to look empty.
"I was in the lower archives," I rasped. The lie felt like lead. "Lost track of time with the... thermal conductivity scrolls."
Akhtar stepped forward, his boots clicking. I could feel the heat of my fever radiating off my shoulder, but I used the Stone to dampen the thermal signature, trapping the heat beneath the mana-tension.
"The archives were locked an hour ago," Akhtar said, his Mana-Sight narrowing. "And your signature... it's erratic. Almost non-existent. What have you done to yourself?"
"I tried to force a cycle," I lied, my voice trembling with genuine pain. "I wanted to reach Tier 2 faster. I think I blew out a conduit. I'm empty, Akhtar."
Akhtar stared at me for a long, agonizing minute. To his sight, I looked like a blown-out fuse—a common casualty of student arrogance. He saw the "absence" of mana and the instability of my signature, but the massive necrosis of my shoulder remained a physical detail lost in the Tower's magical glare.
"Arrogance," Akhtar finally spat, his eyes dimming. "You 'Blank Slates' think you can shortcut the laws of the world because you have no bias. Go. Recover. If you aren't at the training grounds by sunrise, I'll assume you've given up."
I stumbled into my room and bolted the door before collapsing. I pulled back my cloak, and the sight was grim. The physical trauma was severe—blackened, necrotic edges where the hound's fire had lingered.
I closed my eyes and sank into the Library. I didn't go for a miracle; I went for a Heat-Sink.
Thermodynamics forbade me from reversing entropy. I couldn't "heal" the cells—that was re-ordering a disordered system. But I could arrest the decay. I used my last unit of mana to act as a Maxwell's Demon, sorting the high-energy molecules of my fever and pumping them out of the tissue.
Phase One: Endothermic Arrest. I began to draw the heat out of the infected area, dissipating it into the room. The air around me grew warm; my shoulder grew deathly cold.
Phase Two: Stabilization. By lowering the temperature, I slowed the chemical reactions of the rot. I wasn't fixing the bite; I was cryogenically stabilizing it, preventing the necrosis from propagating further.
The bleeding stopped as the vessels constricted in the cold. It wasn't "fixed," but it was no longer dying.
I slumped against the wall, my body shivering violently as my core temperature dropped. The Stone settled, its maintenance draw leveling off as it finished re-calibrating to the Tower's pressure.
[Mana Pool: 1/100]
The sun was touching the spires. In an hour, I had to stand before Akhtar and pretend I wasn't a walking corpse. I had the blueprints of an Architect, but I was currently held together by a single unit of mana and a frozen wound.
The Rogue Path was no longer a secret. It was a countdown.
