Professor Hecate's POV :
The High Tower Academy was a place of absolute, measurable data. Mana-density, vein-conductivity, elemental resonance—everything could be quantified. As a Professor of Combat Theory and a High-Mage of the Silver Circle, I had spent forty years categorizing talent. I knew a genius when I saw one, and I knew a "Dud" when they stepped into my classroom.
But Cassian Valerius was defying the math.
I sat in my private study, the blue light of the scrying mirrors illuminating the silver hair that cascaded over my shoulders. On the screens, the footage of the afternoon's Tactical Maneuvers played on a loop. I slowed the playback down to 10% speed.
"There," I whispered, tapping the glass.
On the screen, Kaelen Voss was unleashing a lightning bolt. It was a Grade-4 strike, moving at speeds a non-mage shouldn't even be able to track. Cassian, looking like a boy on the verge of a heart attack, tripped over a stone.
At normal speed, it was a pathetic stumble. But at 10%?
Cassian's foot didn't catch on the stone. He placed his foot behind the stone and used the momentum to drop his center of gravity exactly 0.4 seconds before the lightning occupied the space where his head had been. It wasn't a trip. It was a localized spatial evasion disguised as a catastrophe.
"And here," I muttered, switching to the Nova Pulse footage.
When Kaelen's electrical wave hit him, the sensors in the arena should have registered a massive bio-electrical spike in Cassian's nervous system. A Null should have been cooked from the inside out.
I pulled up the data-log.
Bio-Sensor Log: Cassian Valerius (First Year)
Impact Force: 400 Newtons (Confirmed)
Electrical Conductivity: 0.0001% (Mathematically Impossible)
Mana Absorption: Null.
The lightning had hit him. The physical force had sent him flying into the wall—I had seen the bruises myself—but the energy had simply ceased to exist the moment it touched his skin. It didn't ground into the sand. It didn't arc through his body. It just... vanished.
I leaned back, my eyes narrowing. Either Cassian possessed a high-level ancient artifact that could negate S-Rank spells—which the Headmaster's initial scan had disproven—or the boy was something much more dangerous than a "Null."
He was playing us.
He was using the Fragility Draught—I recognized the sickly yellow tint in his sclera immediately—to mask a level of combat intuition that shouldn't exist in a fifteen-year-old.
"But why?" I wondered aloud. "If he has this power, why hide in the basement? Why let Kaelen Voss treat him like a footstool?"
The answer arrived with a soft knock on my door.
Elara Valerius walked in. She was the "Perfect Twin," the pride of the first-year cohort, but today her silver aura was jagged, flickering with an anxiety she couldn't hide.
"Professor," she said, her voice tight. "I've reviewed the footage of the spar. I'm an Elite, and even I... I couldn't have timed those 'accidents' that perfectly."
I looked at her, seeing the same doubt in her eyes that was gnawing at my own mind. "You noticed it too, Elara. The 'Lucky Stumble' that happens four times in a row isn't luck. It's a pattern."
"He's my twin," Elara said, her hand tightening on the hilt of her training saber. "We shared a heartbeat for nine months. I know his rhythms. The boy in that arena... he moved like someone who was bored. He wasn't afraid of Kaelen. He was afraid of being caught."
I stood up and walked to the window, looking down at the moonlit courtyard where the First-Years practiced. "The High Priest of the Voss Clan arrives tomorrow for the Blood Appraisal. He brings the Eye of Truth. If Cassian is hiding an artifact, or if he is truly Corrupted by the Rift, that stone will find it."
"And if he isn't?" Elara asked, her voice wavering. "If he's just... different?"
"Then we are looking at the greatest architectural failure in the history of the Valerius line," I said, turning back to her. "Or its greatest weapon. Elara, I want you to be ready. If the Eye of Truth flares red, the High Priest will execute him on the spot. If it flares purple... I want you to be ready to contain him."
Elara's face went pale, but she nodded. As she left, I turned back to the mirror. I zoomed in on Cassian's face as the healers carried him away. For a single frame, just before his eyes closed to feign unconsciousness, he wasn't looking at the sky.
He was looking directly at the scrying camera.
And for that one, brief moment, he wasn't a dying boy. He was a predator watching a bird in a cage.
"You're not a Dud, Cassian," I whispered, a chill running down my spine. "You're a hole in the world."
