Everyone leaned slightly closer.
Roderick pulled out a small object.
It wasn't large, and it wasn't obvious at first glance, but it stood out in a way that was hard to explain. It was a fragment—dark, dull, and strangely out of place.
Seraphine stepped forward, her eyes narrowing.
"…That's not normal."
The fragment didn't glow like mana circuits, nor did it reflect light properly. It seemed to absorb attention rather than attract it, as if it didn't belong in the same system as everything else around it.
Thalia leaned closer but didn't touch it.
"…What is it?"
Sylwen's gaze sharpened slightly.
"Not from the academy," she said.
That much was clear.
Alaric straightened.
"So this is our lead."
Sylwen nodded.
"Yes."
Liora exhaled quietly.
"…And probably our only one."
For now.
Sylwen's gaze drifted back toward the arena, her thoughts clearly moving ahead.
The student was gone, but whatever he had been part of was still active. The system hadn't stopped. It hadn't even slowed down.
They hadn't ended anything.
They had only uncovered a piece of it.
And now—
They had something to follow.
They didn't linger in the corridor any longer than necessary.
The body would be reported, handled, and investigated by the academy authorities soon enough. But whatever they had just found—whatever that fragment was—didn't feel like something they could simply hand over without understanding it first.
Sylwen made the decision without saying it aloud.
"Move," she said quietly.
No one questioned it.
Alaric took the lead, guiding them toward a quieter section of the academy, away from the main corridors and the steady flow of students. Roderick followed with the fragment still in hand, though even he handled it more carefully now, as if instinctively aware that it wasn't something to treat casually.
They stopped in an empty training room.
The moment the door closed behind them, the atmosphere shifted again.
This time, it wasn't tension.
It was focus.
Roderick placed the fragment on a nearby table.
"Alright," he said, crossing his arms. "What exactly are we looking at?"
No one answered immediately.
They all looked at it.
The fragment was small, irregular in shape, and completely unremarkable at first glance. But the longer one looked at it, the more something felt… off. It didn't reflect light properly, and its surface seemed to absorb attention rather than draw it.
Seraphine stepped closer.
"Don't touch it yet," she said.
Roderick raised an eyebrow.
"I already touched it."
"I didn't examine it," she replied calmly. "There's a difference."
Thalia moved beside her, her gaze analytical.
"…It's not emitting mana," she said.
"That's not the strange part," Seraphine replied.
Thalia glanced at her.
"What is, then?"
Seraphine crouched slightly, lowering her gaze to align with the fragment.
"It's interfering," she said.
That caught Sylwen's attention.
"With what?" Liora asked.
Seraphine didn't answer immediately. Instead, she closed her eyes briefly, focusing.
Then she opened them again.
"Perception," she said.
A brief silence followed.
Alaric frowned.
"Explain."
Seraphine straightened slightly.
"When I look at it directly, it seems normal," she said. "But the moment I stop focusing, it becomes… harder to remember."
Roderick blinked.
"…What?"
Thalia's expression shifted slightly.
"…She's right."
That drew everyone's attention.
"I tried to recall its exact shape just now," Thalia continued. "But I couldn't. Not clearly."
Liora frowned.
"That doesn't make sense. It's right there."
"Yes," Thalia said. "And yet…"
She didn't finish the sentence.
Because she didn't need to.
Sylwen stepped closer, her gaze sharpening as she observed the fragment more carefully.
"…A concealment construct," she said.
Seraphine nodded.
"Not a physical one," she added. "A cognitive one."
Alaric crossed his arms.
"So it hides itself… by messing with how we perceive it?"
"Yes," Seraphine said. "Or more accurately, how we process it."
Roderick let out a low whistle.
"That's… annoying."
Sylwen didn't react to that.
Instead, she asked, "Can it be traced?"
Seraphine shook her head slightly.
"Not directly," she said. "But it's not independent."
Thalia picked up on that immediately.
"…It's part of something."
"Yes."
Liora looked between them.
"Part of what?"
Sylwen answered.
"The system."
That word carried more weight now than before.
Alaric's expression hardened.
"You mean the one in the arena?"
Sylwen nodded.
"This isn't just a tool," she said. "It's a component."
Roderick glanced at the fragment again.
"…So we just found a piece of whatever they're building."
"Yes," Sylwen said.
Thalia's gaze sharpened.
"Then we can use it."
Seraphine nodded slowly.
"Maybe," she said. "If we understand how it connects."
That was the problem.
Understanding.
The fragment wasn't giving anything away easily. It didn't emit mana, didn't react visibly, and actively resisted being remembered clearly.
It was designed to exist without being noticed.
Sylwen studied it for a moment longer, then spoke.
"We don't analyze it here," she said.
Alaric looked at her.
"Then where?"
Sylwen's answer was immediate.
"With someone who can."
Liora blinked.
"You mean a professor?"
"Yes."
Roderick frowned slightly.
Sylwen met his gaze.
"We don't have a better option."
That was true.
As much as they wanted to handle it themselves, this was beyond a simple student-level problem now. Whatever they were dealing with had already crossed into something far more complex.
Seraphine stepped back slightly.
"If this is part of a larger construct," she said, "then there's a risk in keeping it."
Thalia nodded.
"It could be linked to something else," she added. "Or trigger under certain conditions."
That settled it.
Alaric exhaled slowly.
"Then we take it to a teacher."
Sylwen nodded.
"Yes."
But before anyone moved, she spoke again.
"Remember this," she said.
They all looked at her.
"This isn't the main piece."
Silence followed.
Roderick frowned.
"…What do you mean?"
Sylwen's gaze remained on the fragment.
"This is just a fragment," she said. "Which means the full structure…"
She didn't need to finish.
They all understood.
It was already in place.
And whatever it was meant to do—
Was still waiting.
For the right moment.
They didn't waste time after that.
The decision had been made, and for once, none of them argued. Whatever this was had already gone beyond them. Acting quickly now mattered more than trying to solve everything on their own.
Alaric took the fragment from the table, wrapping it in a piece of cloth to limit direct contact. Whether that would actually help against something that interfered with perception was unclear, but it felt better than carrying it openly. The group moved together, their pace steady but urgent as they headed deeper into the instructor's wing.
This time, no one spoke lightly.
Even Roderick remained quiet.
The weight of what they had learned pressed on all of them. The fragment wasn't just a clue—it was proof. Proof that something had already been built inside the academy, piece by piece, without anyone noticing.
And now—
They were walking toward someone who might finally see the full picture.
They stopped outside a secured chamber.
Alaric knocked.
A moment later, the door opened.
Professor Kael stood there.
His gaze moved over them quickly, sharp and observant, before settling on their expressions.
"…Something happened," he said.
Sylwen stepped forward.
"Yes."
She didn't waste time explaining everything at once. Instead, she spoke concisely, giving only the necessary details—what they had discovered, the traitor, the death trigger, and finally—
The fragment.
Alaric unwrapped the cloth and placed it forward.
For a brief moment, nothing changed.
Then—
Kael's expression shifted.
Not dramatically.
But enough.
"…Where did you get this?" he asked.
"From the student," Sylwen replied.
Kael didn't touch it immediately. Instead, he observed it carefully, his eyes narrowing slightly as if trying to perceive something that refused to be seen.
"…I see," he said quietly.
That was not reassuring.
Roderick crossed his arms.
"You know what it is?"
Kael exhaled slowly.
"I know enough," he said.
That answer was worse.
Alaric stepped forward slightly.
"Then tell us."
Kael's gaze shifted to him, calm but firm.
"No."
The word landed heavily.
Liora frowned.
"Why not?"
Kael's expression didn't change.
"Because this is no longer a student matter," he said. "You've already done more than expected."
That didn't sit well with them.
Thalia spoke next.
"So we're just supposed to walk away?"
Kael didn't respond immediately. Instead, he picked up the fragment carefully.
For a moment, it looked like nothing.
Then—
The air around it shifted.
Subtle.
But noticeable.
Seraphine's eyes widened slightly.
"…It reacted."
Kael nodded.
"Yes."
He placed the fragment on a nearby surface, his gaze sharpening.
"This is a relay piece," he said. "Part of a larger construct."
They already knew that.
But hearing it confirmed—
Made it worse.
Alaric clenched his jaw.
"Then where is the rest of it?"
Kael didn't answer immediately.
Instead, he looked at them.
One by one.
As if weighing something.
Then he spoke.
"It's already active."
Silence fell.
Roderick frowned.
"…Define active."
Kael's voice remained calm.
"It means whatever it was meant to do—"
He paused briefly.
"—has already begun."
That settled heavily.
Liora stepped back slightly.
"Then we need to stop it."
Kael shook his head.
"You won't."
Alaric's eyes narrowed.
"We just found it. Why can't we—"
"Because you're already late," Kael said.
His tone didn't rise.
But it didn't need to.
The words carried enough weight on their own.
Seraphine's expression darkened slightly.
"…Then what does it do?"
Kael looked at the fragment again.
For a brief moment, something in his expression changed.
Recognition.
Concern.
Then it was gone.
"It destabilizes control systems," he said. "Specifically—mana regulation structures."
Thalia's eyes widened slightly.
"…The arena."
"Yes."
