"Who will be our first volunteer?"

  ?Silence fell over the lecture hall like a heavy blanket. The vast majority of the students suddenly found their desks fascinating, actively avoiding Professor Thorne's eye contact. No one wanted to test their pain threshold against a raw, volatile crystal on their first day.

  ?"I will."

  ?The voice was clear, laced with an unmistakable undercurrent of superiority. From the front row, a girl with perfectly styled hair stood up. A low murmur rippled through the male students as she moved.

  ?Alissa Valentine.

  ?She flicked her hair over her shoulder and walked down the steps toward the podium. Her posture was immaculate, every step calculated to project absolute confidence. She stopped in front of the Professor, lifting her chin to meet Thorne's gaze without a trace of hesitation.

  ?"Proceed, Miss Valentine." Thorne gave a curt nod, the corner of her mouth twitching in anticipation. "I assume you understand the protocol?"

  ?"Naturally, Professor," Alissa replied, her tone flat. "For a Valentine, channeling is as reflexive as breathing."

  ?She extended her elegant right hand and placed it flat against the jagged surface of the raw crystal.

  ?The moment her skin made contact, the crystal flared.

  ?Vzzt!

  ?A blinding blue light erupted. Alissa’s perfectly shaped eyebrows knitted together for a fraction of a second—a micro-expression of pain—before smoothing out into a mask of complete indifference. The ambient temperature around the crystal spiked, radiating a heat intense enough to visibly distort the air above her hand.

  ?From his seat in the middle rows, Marcus squinted. He noticed a faint, white mist curling around Alissa's wrist, pushing back against the heat. She’s using her internal ice-ether to counteract the thermal feedback. Even so, maintaining a localized temperature drop against a raw crystal was a massive drain. Tiny beads of sweat began to form at her silver hairline.

  ?Five seconds. Ten seconds. Fifteen seconds.

  ?She didn't flinch. She didn't pull back. Instead, her amethyst eyes flicked toward the middle rows, locking onto Marcus for a split second. It was a silent, arrogant challenge: Can you do this?

  ?"Enough," Professor Thorne ordered sharply.

  ?Alissa withdrew her hand smoothly. She didn't shake it out or inspect the damage. She simply blew a soft breath over her reddened palm, folded her arms, and resumed her perfect posture.

  ?"Fifteen seconds... maintaining direct contact with an A-Grade raw crystal while suppressing biological reflexes," Thorne noted in her ledger, a genuine glint of approval in her magnified eye. "It seems the Valentine arrogance is backed by acceptable tolerances. Excellent."

  ?"Thank you," Alissa accepted the praise with a slight nod as the hall erupted into applause. Bella, sitting nearby, was clapping so fast and hard she looked like a hyperactive metronome.

  ?"Impressive..." Thorne closed the ledger slowly. "But the demonstration is incomplete."

  ?The Professor’s cold smile returned. She gestured toward the terrified sea of first-years.

  ?"Since you volunteered and set the benchmark, Miss Valentine, I will grant you a privilege." Thorne’s voice dropped to a conversational, yet terrifying volume. "You may select the next participant. Who do you deem capable of following your example?"

  ?Alissa paused. Her eyes immediately lit up with a dangerous, calculating gleam.

  ?She turned around slowly, the movement deliberately dramatic. Every student she looked at seemed to shrink into their chairs, silently praying, Not me. Please, not me.

  ?Alissa’s gaze swept past the front rows, past Gareth's faction, past Roy's sleeping form, until it stopped dead in the middle section.

  ?The corner of her mouth curled upward into a chillingly beautiful, vindictive smile.

  ?Marcus felt a cold drop of sweat slide down his spine. Oh, hell.

  ?Alissa raised a single finger, pointing it directly at his chest like a loaded weapon.

  ?"Since the faculty deemed his group 'impressive' for their survival instincts..." Alissa’s voice carried clearly, dripping with condescension. "I would like to see how he handles a situation where he can't just scavenge trash to save himself."

  ?She tilted her head, delivering the final blow.

  ?"Marcus Eterno. If you please."

  ?The name echoed through the dead-silent hall. Hundreds of heads swiveled simultaneously to stare at him.

  ?Ethan jolted so hard his knee slammed into the desk. Vanessa instantly adjusted her glasses, her jaw tight.

  ?"That aristocratic psycho..." Vanessa hissed through her teeth. "She is actively hunting you."

  ?Marcus let out a slow, controlled breath. He felt like he had just been summoned to the gallows. He met Alissa’s mocking gaze at the front of the room.

  ?"Mr. Eterno?" Professor Thorne prompted, the monocle glinting as she stared him down. "Your peer has issued an invitation. I trust you won't disappoint a lady?"

  ?"On my way, Professor," Marcus replied, his voice deliberately flat.

  ?He pushed his chair back and stood up. His legs felt like they were filled with lead. The walk down the tiered steps felt agonizingly long.

  ?He wasn't afraid of the pain. The slums had taught him how to handle pain.

  ?He was terrified of the variable.

  ?That’s a raw, uncalibrated crystal, Marcus thought rapidly, his eyes fixed on the glowing blue stone. My ether is infected by the Fracture. What happens when an unstable source meets a raw conduit?

  This content has been unlawfully taken from Royal Road; report any instances of this story if found elsewhere.

  ?As he reached the podium, Alissa stepped back to give him space. But as he passed her, she leaned in just enough to whisper.

  ?"Try not to scream too loudly, Eterno."

  ?Marcus ignored her. He stopped in front of the podium. The raw crystal pulsed, radiating a wave of dry heat against his face.

  ?"Hand on the crystal," Thorne ordered. "And remember the parameters. No defensive wards. You absorb the Toll directly."

  ?Marcus swallowed dryly. He took a deep breath, trying to steady his erratic heart rate.

  ?Here goes nothing.

  ?He extended his right hand. His fingers trembled slightly before making contact with the jagged surface.

  ?CRACK!

  ?It sounded like a high-voltage cable snapping.

  ?The moment Marcus's skin touched the stone, the pure blue light of the crystal violently distorted. It began to flicker erratically, as if it were suffocating. Deep within Marcus’s chest, the dormant, jagged energy of the Fracture violently reacted. It surged upward, a territorial, parasitic force furious that a foreign energy signature was attempting to infiltrate its host.

  ?"Ugh—!"

  ?Marcus gritted his teeth, his jaw locking. His right arm began to violently spasm. The veins on the back of his hand bulged, turning a sickly, dark purple, the color rapidly spider-webbing up his forearm. The purple energy wasn't just resisting the blue ether; it was actively crushing it.

  ?Alissa, standing a few feet away, lost her arrogant smile instantly. Her eyes widened in absolute shock.

  ?"What... is that?" she whispered, taking an involuntary step back.

  ?Screeech...

  ?A high-pitched, agonizing sound—like glass screaming under immense pressure—emanated from the core of the A-Grade crystal. Hairline fractures, glowing with sick violet light, began to spread from where Marcus's fingers touched it, webbing across the entire stone. The brilliant blue light was being choked out, replaced by a violent, unstable purple.

  ?"Mr. Eterno! Sever contact immediately!" Professor Thorne barked, lunging forward to physically pull him away.

  ?She was too late.

  ?BOOM!

  ?The raw crystal could not contain the conflicting pressures. It detonated.

  ?Shards of crystal sprayed across the stage like shrapnel. The concussive wave hit Marcus square in the chest, throwing him backward. He hit the stone floor hard, sliding a few feet. Thick, violet smoke curled off his right hand, dissipating into the air.

  ?The Grand Lecture Hall plunged into a horrifying, suffocated silence.

  ?Every single person—including Professor Thorne and Alissa—was staring at the boy on the floor who had just overloaded and shattered an A-Grade raw crystal with a single touch.

  ?The silence broke with the sharp clack of Professor Thorne’s boots. She moved with military speed, dropping to one knee beside Marcus.

  ?"Mr. Eterno! Report your status!" Thorne demanded, her usually glacial voice tight with actual alarm. She grabbed his right wrist with her quartz prosthetic, her eyes scanning his arm for catastrophic nerve damage.

  ?Alissa remained frozen by the podium, staring at the cratered desk and the scattered crystal dust. Her mind was reeling. An A-Grade raw crystal was incredibly dense. It would take a high-tier mage hours of sustained, concentrated output to safely degrade one. Marcus had caused it to detonate purely through uncontrolled feedback.

  ?Up in the stands, Vanessa sat perfectly rigid. Her eyes were locked onto the crystalline debris. Her mind was running through hundreds of equations per second, desperately trying to categorize what she had just witnessed.

  ?That wasn't a standard overload, she thought, her fingers digging into her notebook. That was ether-reflux. His internal energy didn't just resist the crystal; it aggressively consumed and destabilized it.

  ?Marcus lay on the floor, gasping for air. The terrifying, glowing purple veins on his arm were already beginning to recede, sinking back beneath his skin as if the anomaly had never happened. The burning sensation in his chest faded, leaving behind an exhausting, hollow ache.

  ?Thorne, confirming that Marcus's arm wasn't currently undergoing necrosis, let out a sharp exhale. She stood up quickly, turning to face the panicked murmurs beginning to rise from the student body.

  ?"Silence!" Her voice cracked like a whip, instantly snapping the hall back to attention. "Is Mr. Eterno's team present? Come down here and escort him back to his seat."

  ?Ethan, who had already been halfway out of his chair, practically vaulted over the desk in front of him. He sprinted down the stairs and hauled Marcus up by his good arm.

  ?"Hey... you still with me, man?" Ethan whispered frantically. "What the hell was that?"

  ?Marcus didn't answer. He just nodded weakly, letting Ethan support his weight as they walked back up the stairs.

  ?Alissa returned to her seat. The smug satisfaction of singling Marcus out had completely vanished, replaced by a deep, gnawing confusion and a strange sense of defeat. Bella, sitting next to her, didn't look concerned at all. She was swinging her legs, a bright, manic glint in her eyes, giggling softly into her hands as if she had just watched the best comedy show of her life.

  ?Professor Thorne walked back to the podium, her boots crunching on the crystal dust. She swept her gaze over the room, actively suppressing the rising panic.

  ?"Focus, all of you!" Thorne commanded. "What you just witnessed was not a supernatural event. Raw crystals possess inherent structural fragilities when subjected to sudden, violent ether-reflux. It appears the unique signature of Mr. Eterno's... condition... caused a rapid pressurization failure within the lattice."

  ?She brushed some dust off the ledger. "We will proceed. Turn to the next chapter."

  ?To the majority of the room, the explanation sounded plausible enough. But for Marcus, Vanessa, and Alissa, the reality of the situation had fundamentally shifted.

  ?"Based on that display," Thorne continued, pacing the stage, "you should now understand that uncontrolled energy, devoid of proper exchange, leads to catastrophic failure."

  ?She raised her quartz hand, projecting a holographic image of a golden scale, tipping dangerously from side to side.

  ?"The Law of Exchange is not a bureaucratic rule invented by the Council to oppress you. It is the architectural load-bearing pillar of reality." Thorne’s voice dropped, carrying a lethal seriousness. "The ether you draw is not free-floating air. It is excess energy bleeding from dimensional friction. If you siphon it without paying a dividend, you create a localized vacuum. Nature abhors a vacuum."

  ?She stopped pacing, facing the students head-on.

  "Think of the universe as an absolute ledger. Every time you cast, you are taking out a massive, high-interest loan. The 'Pain'—the Toll—is your immediate repayment. If the universe does not receive that payment, the energy debt accumulates within your own biology. Eventually, it will consume your cellular structure until you detonate, much like the crystal did moments ago."

  ?The monocle glinted under the lights.

  ?"We embrace the pain to ensure our vessels remain human. Power without a Toll strips away humanity. It reduces you to a rabid beast, a slave to consumption. The Exchange is the anchor that reminds you that you are violating the laws of physics, and that every violation carries a tax."

  ?"Do you understand? Pain is not a punishment. It is the receipt proving you are still alive, and still in control."

  ?Marcus sat in his chair, his breathing finally stabilizing, but his mind was spinning. Thorne’s lecture was terrifyingly logical. It sounded like an absolute truth of the universe.

  ?Except it completely contradicted the cipher hidden in the library.

  ?['The universe isn't demanding a tax,'] Marcus thought, clenching his fists under the desk. ['Someone else is collecting it.']

  ?After the grueling lecture finally concluded, Professor Thorne dismissed the class. The heavy doors opened, and students flooded into the corridors. The conversation immediately shifted away from Marcus's explosion to the upcoming logistical nightmare: The Second Wave of Admissions.

  ?"Wait, they're still bringing people in?" Ethan asked, looking confused as they merged with the crowd. "I thought the academy was full."

  ?Vanessa smoothly packed her brass-nibbed pen into its case. She looked up, her mind already three steps ahead of the conversation.

  ?"Yes. The First-Year intake occurs in three waves. We were Wave One, primarily drafting from the Western and Central territories," she explained, lowering her voice so only they could hear. "Wave Two arrives this weekend. Mostly Eastern Territory recruits, and the delayed branch-family scions."

  ?"Eastern Territories..." Marcus muttered.

  ?"More importantly," Vanessa adjusted her glasses, her eyes narrowing. "This Friday, the majority of the senior faculty and the Student Council Apex will be stationed at the Spire of Testing to oversee the 'Sacred Scales' evaluation for the new arrivals."

  ?Marcus and Ethan instantly caught on.

  ?"Which means," Vanessa allowed a thin, calculated smile to touch her lips, "this Friday, internal security patrols across the rest of the campus will be operating at minimal capacity. The following day, Saturday, is when they initiate the strict License Checks for the new wave."

  ?"A blind spot," Marcus nodded slowly, the pieces falling into place. "If we're going to breach the Spire of Gears, Friday night is our only operational window."
