The Mechanism Room was not a room.
That was the first thing that resolved upon entry—not a wall, not a ceiling, not the enclosed geometry that the word room had prepared 4,384 students to expect. What the double doors opened into was space. Not infinite, but vast enough that the far boundary was not a wall but a quality change in the light—the specific atmospheric edge of a constructed environment whose designers had been deliberate about the distinction between ending and horizon.
The ground was earth. Not stone, not polished floor—compressed earth with the specific density of terrain that had been walked across and fought across and left unmarked by neither, terrain that held the particular quality of ground that expected to be used. The sky above—if it could be called that—was the flat grey of early morning cloud cover, close enough to the natural article that the eye accepted it before the mind could interrogate the ceiling.
"So this is the fabled Mechanism Room of the Aetherion Academy..." Silas made a feral grin as he witnessed the vast space ahead of him. The three teammates of his winced at the slightest of his movement.
The landscape ran in every direction. Low ridges. Sparse treelines of constructed timber that cast real shadows. Open ground that funneled movement between natural corridors. Supply positions marked by the stacked geometry of crates—wood, iron-banded, distributed at intervals that weren't random. Food crates marked with a single carved line. Weapon crates marked with two.
The cohort moved through the entrance in a continuous flow and spread.
Then, the wristbands appeared.
Not distributed. Not handed across by waiting faculty. Present—the specific arrival of something that had been waiting for the correct condition and had found it. Solid mana given hardware form, each band settling at the wrist with a weight that was exact rather than approximate. On 4,384 wrists simultaneously. The cohort's forward momentum stuttered, the specific collective pause of people processing a physical event they hadn't anticipated.
"This is..." Isaac stared at the wristband that suddenly appeared on top of his right wrist.
This flow of mana... His eyes narrowed. Thorne's [Grounded Circuit].
Then, the Proctor's voice carried from everywhere and nowhere—built into the room's architecture the same way the artificial sky was built into it, sourceless and total.
"The devices on your wrists are the combined product of three skills." The acoustics gave the announcement the flat authority of something that wasn't performing authority, simply possessing it. "Master Thorne's [Grounded Circuit]. Master Andrias's [Mana Mimicry]. Mr. Raul Ignis's [Synthesis]. They are not meant to be decoratives."
Isaac turned his wrist, further inspecting the wristband.
Thorne's [Grounded Circuit] is much more stable in this band than what I observed two days ago. Isaac recalled when Thorne absorbed Jax's [Bolt Streak] which he deflected. It serves as the engine of this device's hardware, the production of Andrias's [Mana Mimicry]. They complement one another in a very profound manner such that they elongate their lifespans...
Isaac deduced that it must be the doing of the third skill mentioned, Raul Ignis's [Synthesis]. It was more than just what the name of the skill suggested.
"The Manafold Circuitry of this room is connected to every device you are wearing. The room reads your device the way it reads itself—as an extension of its own architecture. Any damage inflicted upon you beyond the established threshold will be registered as damage to the room's own system. The room will respond accordingly. Your device will disengage. You will be expelled from the assessment."
A pause with the weight of something that was going to be followed immediately.
"Disqualification."
Some students flinched at that. Some others remained composed.
"This is ridiculous," growled Tomlin. "We don't even know what this assessment is for, and now, there is disqualification?"
"...I do have an idea of what it may be." Seren then voiced, earning Tomlin's attention. Instead of finishing her words, however, she turned to Cassiopeia. "Are you thinking the same as I am, Cassiopeia?"
"High nobles must have gotten the hint by now." Cassiopeia, as she filed something in her notebook, stated without looking up from it. "Class designation."
"Huh? But—" Tomlin objected, wide-eyed. "It is widely known throughout the entire kingdom that class designation is done through a tournament-based, one-versus-one format!"
Neither Cassiopeia nor Seren replied to Tomlin, much to his awkwardness.
Isaac raised his head up at the high ceiling of the Mechanism Room as he listened to the conversations of his teammates.
"The devices also monitor physiological state. Excessive malnourishment. Dehydration. Any condition that crosses the threshold of what this institution considers an acceptable margin of physical deterioration. These conditions will trigger the same response." The voice moved across the dispersed cohort with the same quality it had moved across the grand hall—present everywhere, directed at no one specifically. "Food crates and weapon crates are distributed throughout the terrain. One carved mark. Two carved marks. You have eyes."
The grey light held. The constructed treelines cast their real shadows across the open ground.
"Your objective, again," the Proctor said, "is to find the exit."
"Three days. The assessment concludes at the seventh bell on the third day. Any student still present at that point will be evaluated on their performance within the room up to that moment."
He paused.
"Find the exit. That is all."
The voice ceased.
The Mechanism Room received 4,384 students in silence.
Isaac stood at the threshold's interior edge and held it all at full resolution.
Wristband. Exit. Class designation.
[The Prism] was already running. It was always already running.
Class designation as in... the separation of 4,384 students into four groups. 16 top class—the representatives of the grade. 84 elite class—destined to be the officers of the militia. 1,000 combat class—those with combat potentials. And the commoner class—the general stream.
Class designation involved the stratification of the entire grade. It was an assessment of enormous scale, commonly known to be held via a long series of one-versus-one tournaments, as Tomlin had stated.
If this assessment is truly about class designation, the rumor—which Elara relayed to me—that the evaluation is entirely team-based must be the false information.
Exiting his thoughts, Isaac observed his surroundings. His teammates seemed to be in thoughts of their own.
Currently, there were two motives driving students forward.
One, the exit. Two, the disqualification.
Both incentivize those who move. In other words, the evaluators want students to combat. They want to generate a situation that mimics a war.
"What now?" Tomlin was the one to break the ice. "We need to secure food before starting our search for an exit, don't we?"
It was a logical solution.
"Yes." Cassiopeia, the previously elected leader of Group 13, closed her notebook. "Three-day window is very long for a test. Expect little to no sleep. Given how we don't know the total amount of food scattered throughout the room, the safest option is to discard searching for the exit entirely and focus on stacking enough food to prevent disqualifications."
Seren nodded. "I agree. It is the safest measure that we can take."
Tomlin peeked at Isaac, who remained silent. Returning his gaze to Cassiopeia and Seren ahead of him, he voiced, "Well then, it looks like our course of action is decided. Shall we get going?"
Cassiopeia, with eyes that held a cold, calculating gleam, led the group forward by taking the first step. Seren followed immediately, and Tomlin walked behind the two, trying not to fall back.
Isaac, being the one to tail them, began moving as well.
The lower the assigned number of a group, the more danger they likely are.
After all, one user of a high-ranked skill tends to be more dangerous than four users of generic, D-ranked skills.
Silas Fulgur and Lyra Aetherion.
Isaac remembered the brief exchange between the two just before entry into the Mechanism Room.
Something is about to happen—something big.
___
Silas and his three teammates had moved northeast from the entry point within the first two minutes.
Not because northeast offered any particular strategic advantage. Because northeast was the direction Silas had chosen, and Silas had never spent more than three seconds on direction.
The three F-ranks followed in silence. The worthless bags designation had settled over them like weather—not argued against, simply carried. They moved because the alternative was being left alone in terrain they didn't understand, and that seemed worse.
He found the first weapon crate at the forty-meter mark. He didn't open it. He looked at it, confirmed it contained weapons, and kept moving. He had [Lightning Spear]. The crate had nothing that improved on that. It was the three F-ranks who cracked it open instead and took what they could carry—short blades, a buckler, a single reinforced staff. Their hands were less empty now. Whether that mattered was a different question.
"Surrender yourself, Silas Fulgur. We have the high ground."
He found them at the ridge.
Eight groups. 32 students. Arranged across the elevated terrain in a perimeter that covered the approach corridor in every direction—the specific geometry of people who had not arrived simultaneously but had converged. The draw results had been public since yesterday. They had known Group 1's composition since the tile assignments.
Silas stopped.
He looked at the perimeter.
Then he grinned.
It wasn't a pleasant grin. It was the specific expression of someone who had walked into a room expecting a meal and found a banquet—not gratitude, appetite.
"Eight groups," he said, to no one in particular. His voice carried without effort, the natural projection of someone who had never once considered lowering it. "Numbers?"
"From three to ten," one answered.
Silas laughed. He looked across the ridge with the bright, dangerous attention of someone whose interest had just been genuinely caught. "I didn't think this room had anything worth my time except group two. I'll correct that assessment—now this is unexpected."
From the ridge's center, a young woman with the composed bearing of a high noble stepped forward. A-rank: [Mystical Swords]—seven blades of condensed mana already orbiting her forearms in slow, deliberate rotation, each one trailing light the way a drawn edge trails air, their tips sharp enough that the space around them distorted faintly as they moved. This was Camilla Hedron, and she moved with the unhurried authority of someone who had never needed to raise her voice to command a room.
To her left stood a broad-shouldered young man with both palms pressed flat against the ridge's surface. A-rank: [Earthshatter]—the ground beneath Bart Ossel was already responding, fissures spreading outward from his palms in controlled fracture lines, the ridge's terrain cracking into raised slabs that tilted and locked at his direction. He could heave terrain. The ridge itself was a weapon in his hands, and he had been reshaping it since the coalition arrived.
Beside Bart, a lean young woman with close-cropped hair stood with blades extended at both sides—not ordinary blades, the specific edge of mana given a cutting geometry so fine it caught no light at all. A-rank: [Mirage Slash]—a skill that paired displacement with offensive output, each movement of its user leaving a trailing cut in the space vacated, as though the air itself remembered where the edge had been. Her name was Neve Cassin, and she had already repositioned three times in the span of this conversation, leaving invisible geometries in the air behind her.
Further along the ridge, a heavyset young man exhaled once and changed. A-rank: [Juggernaut]—a full physical transformation, the user's mass and density multiplying to a degree that made the ridge compress slightly under his feet. Pol Drevin's skin had taken on the dull, unreflective quality of something that had stopped being soft. Conventional weapons wouldn't register. A practitioner without significant output couldn't move him. He was the formation's intended anchor—not because they had assigned him the role, but because stopping him once [Juggernaut] was active was the kind of problem that required its own answer.
To the right flank, two more group leaders stood together with the proximity of people who had agreed on something before the formation assembled. The first: A-rank: [Ashfall]—a skill belonging to a quiet young woman named Sera Voss, who had already seeded the air around the ridge's right flank with a suspended field of burning cinders, each one invisible at rest and catastrophic in motion. The field waited. When she gave it direction it would descend as a curtain of accumulated fire, not a single strike but a sustained condition applied to everything within range. The second: A-rank: [Chain Labyrinth]—a restraint skill of a different order, belonging to a young man named Idris Callow, who held both palms outward with chains of compressed mana already manifested between his fingers, each link dense enough to stop a charging practitioner mid-stride. He hadn't thrown them yet. The labyrinth was the threat—not the chains themselves but the geometry they could produce, the enclosed space they could construct around a target in seconds.
The seventh A-rank was elevated at the ridge's highest point with the placement of someone whose skill had range and had been using it since arrival. A-rank: [Storm Veil]—a weather-aspected technique belonging to Oriel Fenn, and the local atmosphere above the ridge had already changed. Not subtly. The air directly overhead had the specific quality of a confined storm front—pressure differential visible in the way the constructed treelines bent without wind, lightning accumulating in the cloud layer the skill had seeded across a thirty-meter radius. When she released it, everything within that radius would receive it simultaneously.
Seven A-rank skills. Arranged across elevated terrain. Numerical advantage confirmed.
"We have seven with A-rank skills." Camilla's [Mystical Swords] continued their slow orbit, unhurried, the patience of someone who had never needed to rush. "Even you won't be able to go through all of us." Her sharp eyes narrowed as she clenched her hand in a threatening motion. "I am Camilla Hedron. Have you heard of my name?"
"A-rank: [Mystical Swords]," replied Silas, lazily.
"Good. Then you should know what I am capable of. Alone, you stand no chance against our combined skills. Silas Fulgur, we will say this once more." She gave his name with the flat authority of someone naming a problem they had already solved. "Surrender your wristband."
Silas looked at the seven A-rank signatures arrayed across the ridge. He could feel them—the mana output of skills that had been trained past the casual threshold, the specific weight of power that announced itself in the ambient air the way S-rank announced itself in his own hands.
[Earthshatter] fracturing the ridge's foundation in preparation. [Mirage Slash] threading invisible cuts through the air at every position Neve had vacated. [Juggernaut] radiating the dense, immovable output of a transformation already completed. [Ashfall]'s suspended cinder field waiting overhead. [Chain Labyrinth]'s geometry already half-constructed between Idris's hands. And [Storm Veil]—thirty meters of seeded storm front held at the threshold of release, the air above the ridge coiled with the accumulated intent of a skill that had been preparing since before the conversation began.
And Camilla's [Mystical Swords]—seven blades whose orbits had tightened fractionally since she stepped forward. Ready. Coordinated. Real.
His grin widened.
"I've been wondering," he said, conversationally, "what I can actually do."
He raised his hand.
"Let's find out."
Everyone in the formation tensed, save Silas.
The air began to crackle. The smell of burnt ozone spread rapidly. Then—in a split second—there was the monstrous calamity, the unkempt judgment of the thunder god. [Lightning Spear] arrived in his hand.
Not as a technique. As a declaration—the full, unrestrained expression of S-rank skill from a practitioner who had decided that restraint wasn't necessary for this specific moment.
At this moment, everyone in the Mechanism Room read the fluctuation. Even from long distance away, through treelines and ridges and the grey diffusion of the artificial sky, every practitioner with a functioning sense of mana felt it—the specific quality change in the air that S-rank output produced when it stopped being contained. Students mid-movement paused. Group leaders looked up. Thorne, observing from a faculty vantage point built into the room's architecture, wrote one line in his notebook without looking down at it.
Camilla's eyes widened. Her [Mystical Swords] snapped from orbit into forward formation—seven blades positioning in the layered defensive array that the skill's higher applications could produce. "Everyone, now—"
0.3 seconds. Such was the time available.
Bart Ossel's [Earthshatter] detonated upward—slabs of compressed earth rising in a barrier wall between the coalition and the source of the fluctuation. Oriel Fenn's [Storm Veil] broke from preparation into full release, the seeded storm front discharging downward in a column of accumulated lightning and pressure that reshaped the air inside its thirty-meter radius. Idris Callow's [Chain Labyrinth] launched—chains of dense mana erupting outward in a constructed geometry intended to enclose and arrest. Neve Cassin's [Mirage Slash] fired from three positions at once, the invisible cuts she had seeded throughout the conversation releasing simultaneously. Pol Drevin lowered his head and held. Sera Voss released [Ashfall]—the suspended cinder field above the right flank descending in a curtain that turned the air inside it into something that burned continuously.
The speed wasn't enough.
The [Lightning Spear] left Silas's hand.
Then, a flash.
The sheer force generated from the strike was enormous. What had been a ridge became a crater. The blast radius sent compressed earth, severed timber, and ionized air in every direction simultaneously—not the careful minimum work of a practitioner managing output, but the specific quality of someone who had opened a door they usually kept mostly closed and was now looking at what was behind it with frank curiosity. Camilla's seven blades shattered on contact—[Mystical Swords]' layered defense meeting an output that exceeded the threshold it had been built for. Bart's barrier wall of heaved earth was consumed in the same instant it rose. Oriel's [Storm Veil] discharged into the impact and was swallowed—its thirty meters of accumulated storm meeting the bolt and losing. The [Chain Labyrinth] disintegrated before its geometry closed. [Ashfall]'s curtain scattered. Pol Drevin's [Juggernaut]—the formation's anchor, the thing that was supposed to be unmovable—was carried backward by the shockwave with the specific quality of something that had been built to resist impact and had found an impact larger than the design.
The three F-ranks behind Silas, even with their arms shielding their faces, were knocked back, rolling powerlessly.
When the smoke and the dust cleared, none of the enemies remained.
With a single [Lightning Spear], all 32 were disqualified. Seven A-rank skills among them. The coalition that had taken ten minutes to assemble across a ridge had been removed from the assessment in under a second.
"Hah... hahahaha!" Silas roared as he looked beyond the crater at the terrain ahead. The artificial sky held its grey light unmoved. The constructed treelines spread in every direction with the deliberate geography of a battlefield built to generate movement. "Do you see that?! The might of the S-rank skill?!"
His voice carried across a significant portion of the Mechanism Room. Students who had already put distance between themselves and Group 1's entry vector heard it anyway. Some moved faster. Some stopped moving entirely and reassessed their direction.
Silently, almost to himself, Silas said, "There is no one who can oppose me in this test."
His grin didn't fade.
Somewhere in the grey geography ahead, Group 2 was moving.
Lyra Aetherion.
Don't you think you're going too far?
The question had been sitting in his awareness since the grand hall. Not bothering him—no, it didn't bother him at all. He simply wanted to fight the princess of the kingdom. The supposed genius who walked in the footsteps of the infamous Prince Gladius Aetherion—the royal heir, the next king, the name the kingdom said with a specific reverence it reserved for very few things.
He wanted to see what the shadow of that name actually contained.
He turned to the three F-ranks, who had not moved from their original positions. They were looking at the crater the ridge had become with the specific expression of people revising a prior understanding at significant speed.
"Keep up," Silas said. Already moving. "Or don't. I have somewhere to be."
He descended from the shattered ridge and moved into the terrain.
The hunt for Group 2 had begun.
