STORIES. PROFESSOR THORNE GAVE THEM TWO WEEKS AND ONE WORD. EVERY VERSION AGREES ON THE WORD.
The House Book of Opus.
The air pressure dropped.
It happened in the space between one breath and the next, a sudden vacuum, as if the room had inhaled. Then the thunderclap hit.
BOOM.
It shook the safety pillars in their housings. It vibrated in Silas’s teeth, sternum, and the welds of the railing he was gripping. The murmuring died as if someone had cut a wire.
The silence that followed was absolute.
Standing on the central dais was a man who looked like he had walked out of a hurricane and not bothered to clean up afterward.
Professor Thorne was tall, with skin the color of tanned leather and shoulder-length hair that looked wind-whipped, gray at the temples and darker everywhere else. He wore the standard instructor’s robes, but he wore them as a ship captain wore a coat, open at the collar, sleeves pushed back, the garment shaped by the body beneath it rather than the other way around. The collar gap revealed a chest scarred with fern-like burn patterns from lightning strikes that branched up his neck and disappeared into his hairline, pale and raised against his darker skin, like a river delta mapped onto flesh.
He checked a pocket watch. Snapped it shut.
“Seventh bell. Precision.”
His voice cut, static electricity given words, carrying to the top tier without amplification, arriving at each ear with the sharp clarity of a blade laid flat against skin.
“I am Professor Thorne. My affinity is Storm, bonded to a Typhoon Roc. A volatile triad of Air, Water, and Lightning. In this hall, you will learn the difference between being a conduit and being a victim.”
He paced the dais, hands clasped behind his back. His eyes scanned the rows, lingering on the bored faces of the nobles on the first tier and the terrified faces of the Undrafted on the upper rings.
“The objective is simple. You are all Wood Tier. Your cores are soft, permeable. You leak what mana you have like a cracked cup. Two weeks from today, you will stand for the Copper evaluation. You will condense your cores. You will seal the cracks. You will become solid. Those who do not go to Remedial, and Remedial has until the end of term to save you from the Warden’s promise.”
He stopped pacing.
“He knew the number before he came in,” Silas said, low, to Kent. “Watch him. He’s already counted who goes.”
“Those who fail to do so will be removed from my class. If you cannot conquer the low bar of the very basics in that time, you do not deserve my teaching.”
Thorne raised a hand.
“Some affinities are malleable, like Water, they flow into the shape you give them. Some are projective, like Fire, they want to leave the body, to strike and burn. Some infuse, like Earth, they harden what’s already there, turning flesh to stone and bone to metal. These are the three fundamental modes of mana expression. Water, Fire, Earth. All mana can do all forms, but yours will naturally flow easier to one of the three. A fire user can armor herself, and an earth user can strike at range. Each pays double for working against the grain.”
He snapped his fingers. A ball of mana materialized in his palm, a miniaturized storm. Tiny arcs of blue lightning crackled around a sphere of compressed, howling wind, dampened by a swirling layer of water. It spun fast enough to blur, humming like an angry hornet.
“Control,” Thorne said.
He flicked his wrist. The ball screamed upward, so fast it blurred, and exploded against the reinforced ceiling wards with a deafening CRACK-HISS, dissipating harmlessly. The shockwave ruffled hair on the upper tiers.
“That was Blasting,” Thorne said into the ringing silence. “Raw projection. You form a construct, you launch it. It’s the crudest form, pure force expelled from the core through the channels and out through the extremities. Every first-year wants to blast. It’s dramatic. It’s satisfying. It’s also the least efficient use of mana you will ever learn. You lose sixty percent of your energy to waste heat and dispersal. Blasting is a hammer. Sometimes you need a hammer. Most of the time, you need something sharper.”
He held up his right hand. Lightning crawled across his knuckles in a sheath, a crackling glove of blue-white energy that hugged his fingers and extended past his fist in a tapered point. The air around his hand ionized, the smell of ozone cutting through the ambient mana like a blade through cloth.
“Armament,” Thorne said. “You don’t project the mana outward, you hold it. You shape it around your body, a weapon, or a limb. The energy stays in contact with your channels, which results in less waste and more control. A Fire user doesn’t throw a fireball, she coats her blade in flame. An Earth user doesn’t launch a boulder, he hardens his skin with stone until it can stop a spear. Armament is the close combat warrior’s form. It requires sustained output and fine motor control. Most Copper-tier students spend weeks learning basic Armament before they can hold a shape for more than five seconds.”
This novel's true home is a different platform. Support the author by finding it there.
The lightning glove dissolved. Thorne lowered his hand.
“And the third form.” He didn’t demonstrate this one. He stood still, and the air around him changed.
It was a subtle shift in pressure, a faint electric taste appearing in the back of Silas’s throat. The mana-lanterns on the nearest pillars flickered. The hair on Silas’s arms rose. The ambient temperature dropped by two degrees, a pervasive, even chill that seemed to emanate from Thorne in all directions like a field of influence that didn’t care about walls or distance.
“Area,” Thorne said. “You don’t project and you don’t armor. You saturate. You push your mana outward in a field that alters the conditions around you. A Fire user can raise the ambient temperature until the air itself ignites. A Water user increases the humidity until it rains indoors. An Earth user can change the ground density until it becomes quicksand.”
He let the field dissipate. The temperature normalized.
“Area is the rarest form for a reason. It requires the largest mana reserves, the finest control, and the most sophisticated understanding of your affinity’s interaction with the physical world. These are just the beginning. True masters of their mana affinities can make the miraculous look mundane at higher tiers.”
Walking to the center of the platform, he raised his arms and his eyes turned the crackling white of lightning. Gasps rose from the tiers as arcs of lightning danced around his arms and up toward the domed ceiling, spinning faster and faster until a tornado of pure electricity hummed in the center of the room. He clapped his hands with a BOOM. The tornado dissipated, the students visibly exhaling as the bright white left his eyes. Silas caught sight of Malachai and they were both wide-eyed with fear and awe.
Professor Thorne turned and walked slowly up the ramp to the fourth tier. The students held their breath as he passed. He stopped directly in front of Silas’s platform.
Thorne looked at him. Piercing, electric-blue eyes that held the attention of a man who had read a file and found something in it that didn’t fit.
He tapped the railing with a scarred finger.
“Some affinities follow different rules entirely. The Academy provides leverage for the known variables, Mr. Riccard. Your intake file says ‘Unknown Classification.’ You are an outlier.” The word was delivered without inflection, a clinical statement of fact. “You will have to build your own path, I’ve not experienced an unknown affinity before.”
He turned back to the class.
“Today you begin. Initialize Affinity Aids.”
He pressed a heavy red button on the brass console as a siren began.
The room roared.
Malachai’s platform hissed open first.
A small, bubbling cauldron of viscous green liquid rose on a pedestal, acid-sharp, chemical, the smell stinging Silas’s eyes from two platforms away. Malachai leaned over the fumes and inhaled deeply. “Yes,” he whispered, his eyes closing, the green light behind his lids flaring. “That’s it.”
Alice’s railing ignited. A ring of six smokeless blue-fire torches erupted around her platform, the heat shimmering in the air, distorting the view of anyone trying to watch her work. She didn’t flinch. She spread her hands and let the fire warm her palms, her expression the satisfaction of someone reuniting with something that had always belonged to them.
Along the walls, shutters snapped open, revealing high-speed turbines that blasted directed air currents at the wind-aligned students. On the lower tiers, piles of raw ore rose from the floor with grinding crunches for the Earth artists. Water pools materialized in shallow basins for Aquarius bonds. Green light pulsed from crystalline grow-lamps for the Naturis students as affinity-specific plants were dropped off by attendants, and on the far side of the Silo a platform began emitting a deep, subsonic vibration that made the air around it feel heavy, a gravity aid for one of the rarer affinities.
One hundred and fifty platforms, each one reading the core standing on it. One hundred and fifty loops, each feeding on the core it read. The room was a din of bubbling, burning, blowing, and grinding, a sensory assault that was also a tool. The aids were mirrors. Each one reflected the student’s affinity back at them, creating a resonance that accelerated the cycling process. The fire burned hotter near Alice because Alice burned hot. The acid bubbled stronger near Malachai because Malachai’s toxicity fed it. The system amplified what was already there.
Silas waited.
He could feel the pull of the aids around him, each one tuned to its student. The element called to the element, and the core answered, and the cycling ran faster toward Copper under that pull.
He heard a mechanical clicking beneath his feet. Gears ground together. Something in the platform’s mechanism was searching, cycling through a catalogue of known affinities, looking for a match. Silas felt the floor plates shift, testing configurations, the system trying to produce a stimulus.
Then, silence. The gears stopped. Nothing rose. The floor remained smooth, black stone.
A vacuum of stillness in a hurricane of elemental feedback. One hundred and forty-nine platforms active. One dark. The system had searched its catalogue and found no match for whatever the Tardigrade had left in Silas’s chest, and so it had done the only honest thing: nothing.
Nearby students glanced over. A Geomacus boy on the next platform smirked. On the second tier, the Margrave’s son noticed the empty platform and nudged his neighbor, whispering something that made them both laugh.
Silas kept his face blank. Unknown Classification. The system didn’t have an aid for him. It didn’t know what a Tardigrade needed. Vacuum? The cold between stars? A pressure so deep it bent light?
“Sit,” Thorne boomed from the dais, his voice cutting through the elemental noise. “Begin cycling your mana. Visualize your core. Collapse it. Squeeze the space between the mana particles until they lock together. You are looking for the snap, the moment the core transitions from Wood to Copper density.”
The room dropped into a focused hum, one hundred and fifty students cycling simultaneously, the combined draw on the ambient mana creating a current that Silas could feel tugging at his chest.
He sat cross-legged on the cold stone and closed his eyes.
His core was there, the sphere of shifting silver sand suspended in the hollow behind his sternum. It looked wrong. The cycling manuals Kent had been studying described a smooth, gem-like seed. This was a distortion, a region where the mana moved at multiple speeds simultaneously, the grains of silver sand accelerating and decelerating in patterns that defied every cycling technique Silas had read about.
He tried to apply pressure, mentally wrapping his will around the sphere and squeezing, treating the mana like iron on an anvil, the only metaphor his body understood. He looked for the place to strike; the sweet spot where compression would create density, where force would produce structure.
But every time he swung the hammer, the anvil moved.
