They didn't follow him.
That was the first decision they held onto without wavering. Even as the second-year student disappeared into the flow of volunteers, none of them made a move to chase. It went against instinct, especially for Alaric and Roderick, but they understood the risk now. Chasing the person meant losing him again. Following the pattern meant uncovering something bigger.
Sylwen shifted her attention back to the circuit, her expression calm but focused.
"We need all confirmed points," she said.
Liora nodded immediately and began organizing their findings.
"Four locations," she said after a moment. "Possibly five if we include the unstable one Thalia found earlier."
"That's enough," Sylwen replied.
Thalia stepped closer.
"For what?"
Sylwen turned slightly, her eyes sharper now.
"To see the shape."
Seraphine moved beside Liora, glancing at the rough layout.
"Mark them properly," she said.
Liora quickly sketched the arena, placing each confirmed point. It didn't take long before the pattern started forming, and once it did, none of them could ignore it.
Alaric leaned forward slightly.
"…That's not random."
He was right. The points weren't scattered across the arena. They were narrowing, forming something structured rather than chaotic.
Thalia studied it for a moment longer before speaking.
"…It's converging."
Sylwen nodded.
"Yes."
Seraphine traced a line between the points with her finger.
"They're not just connected," she said. "They're being directed."
Liora looked between them.
"Directed where?"
There was a brief pause before Sylwen tapped the center of the layout.
"Here."
The central platform.
They had already suspected it, but now it wasn't a guess anymore. Everything pointed there.
Alaric straightened slightly.
"So everything leads to the center."
"Yes," Sylwen said.
Roderick frowned.
"Then why didn't he finish it?"
The question hung in the air.
Seraphine answered first.
"Because he's not done," she said. "Or because he's waiting for the right moment."
Thalia added quietly, "This isn't something meant to activate immediately."
Sylwen nodded.
"Timing matters."
Alaric crossed his arms.
"So this is something that triggers later."
"Yes."
Liora's expression tightened.
"During the event?"
Sylwen didn't answer, but she didn't need to. The implication was clear.
If they were right, then whatever the intruder was building wasn't meant for now. It was meant for the Third-Year Event, when the arena would be filled with students, instructors, and spectators.
Roderick let out a slow breath.
"…That's a big problem."
"Yes," Sylwen said calmly.
Thalia's gaze hardened.
"Then we stop it now."
It was the obvious answer.
But Sylwen shook her head.
"No."
Alaric frowned.
"Why not?"
"Because we don't understand it yet," Sylwen replied. "If we destroy it without knowing how it works, we might miss something important."
Seraphine nodded.
"And if this is part of something bigger, then removing it blindly could make things worse."
Liora hesitated.
"But waiting is risky too."
"It is," Sylwen admitted. "But acting without understanding is riskier."
That was difficult to argue with.
Alaric looked back at the layout again.
"…So we keep watching."
"Yes."
Roderick shook his head slightly.
"You really like waiting."
Sylwen didn't react.
"It works," she said simply.
There was a moment of silence before Thalia spoke again.
"He'll come back."
Sylwen nodded.
"He has to."
Seraphine added, "If this is unfinished, then he'll return to complete it."
Alaric glanced toward the volunteers.
"…Then next time, we don't just observe."
Sylwen's gaze sharpened slightly.
"No."
Her tone was steady, but there was intent behind it now.
"Next time, we catch him."
The arena continued moving around them as if nothing had changed. Students worked, mana flowed, and the structure of the event slowly took shape.
Everything appeared normal.
But now they knew the truth.
Something was being built beneath that normalcy, something deliberate and controlled. It wasn't rushed, and it wasn't random. It was patient.
And when the time came—
It wouldn't be small.
Understanding that everything led to the center was one thing, but acting on it without fully grasping the purpose behind it was another. Sylwen didn't rush, and the others followed her lead. Instead of reacting impulsively, they shifted their focus again—this time toward understanding how the system was being maintained.
Because if the setup was incomplete, then someone still needed to return and continue it.
"Watch the timings," Sylwen said quietly.
Alaric glanced at her, slightly confused.
"Timings?"
She nodded, her gaze still fixed on the circuits.
"He's not moving randomly," she explained. "He's returning at specific intervals."
Thalia understood immediately.
"…So there's a pattern."
"Or a trigger," Seraphine added, her eyes narrowing slightly as she observed the mana flow.
Roderick smirked faintly.
"Either way, that means he's coming back."
"Yes," Sylwen replied calmly.
Liora looked around more carefully now, her unease growing as she scanned the volunteers.
"Then we just wait for him again?"
Sylwen shook her head slightly.
"No. This time, we don't just wait."
Alaric raised an eyebrow.
"…We force it?"
Sylwen gave a small nod.
That changed the approach entirely. If the intruder was following a pattern, then disrupting that pattern at the right moment could force him to act before he was ready. It wouldn't just expose him—it would give them control over the situation.
Thalia stepped forward, her focus returning to the circuit.
"If I disturb the flow again," she said, "it should trigger a reaction like before."
Seraphine considered that for a moment.
"But if we do it at the wrong time, he might ignore it," she said. "Or adapt."
Sylwen nodded.
"Exactly. That's why timing matters."
Roderick sighed.
"Everything with you is about timing."
Sylwen didn't respond to that. Instead, she watched the circuit closely, waiting for the mana flow to settle completely.
Seraphine spoke again after a few seconds.
"The system is stabilizing," she said. "It's almost back to its original state."
Thalia nodded.
"Then this is the moment."
Sylwen didn't hesitate.
"Do it."
Thalia moved immediately. Her hand hovered over the circuit before making a precise adjustment—small enough to avoid suspicion, but enough to disrupt the flow.
The mana pulsed.
Once.
Then again.
Stronger than before.
Alaric's posture tightened.
"He'll notice that."
"Yes," Sylwen said.
This time, they didn't wait passively. Their attention shifted outward, watching not just the circuits, but the people around them.
At first, nothing happened.
Then—
Seraphine noticed it.
"That one," she said quietly.
Her gaze locked onto a student near the edge of the arena. He wasn't the same one as before, but his reaction was familiar.
A slight pause.
A moment too long.
Then movement.
Sylwen followed her gaze.
"…Second-year," she said.
Thalia narrowed her eyes.
"Another one?"
That changed everything.
Alaric's expression hardened.
"So it's not just one person."
"No," Sylwen said.
Her voice remained calm, but there was a deeper realization behind it now.
"It never was."
The student began moving toward the circuit. His steps were steady, controlled, blending naturally with the surrounding activity.
But now, they could see it.
The intent.
Roderick smirked slightly.
"Looks like we've got another one."
Sylwen shook her head.
"No."
She took a step forward, her gaze steady.
"Not another one."
She paused briefly.
"Part of the same system."
That realization settled heavily over the group. They weren't dealing with a single traitor anymore. This was something structured, something coordinated.
Thalia stepped forward, her posture shifting into readiness.
"Then we stop him here."
This time, Sylwen didn't object.
They moved as one.
The student reached the circuit, his hand moving toward it as if to continue the work that had been interrupted earlier.
But before he could act—
Alaric moved.
Fast.
His hand shot forward, grabbing the student by the shoulder and pulling him back.
The student reacted instantly, twisting his body to break free. But this time, he wasn't facing a single opponent.
Roderick stepped in, blocking his path. Thalia moved to his side, cutting off another escape route. Liora stepped back slightly, keeping the area clear while maintaining awareness of their surroundings. Seraphine observed closely, her eyes already analyzing every movement.
The student froze.
Only for a moment.
Then he smiled.
"…So you figured it out," he said.
Sylwen stepped forward, her expression unchanged.
"No," she replied calmly.
"Not everything."
The student's smile widened slightly.
"That's good," he said.
"Because it means you're still behind."
The moment the student spoke, the tension shifted.
This was no longer just a simple confrontation. It was confirmation that they were dealing with something far more organized than they had initially assumed. The person in front of them was not just a student who had been caught—he was part of something structured, something deliberate.
Alaric tightened his grip on the student's shoulder.
"You're not going anywhere this time," he said firmly.
The student didn't resist immediately. Instead, his eyes moved briefly across the surroundings, as if checking something unseen. That moment of stillness was subtle, but it did not go unnoticed.
"That's unfortunate," student said calmly.
Then he moved.
His body twisted sharply, slipping partially out of Alaric's hold as he dropped his center of gravity and drove his elbow backward. The movement was fast and efficient, not wild or desperate. Alaric reacted instantly, blocking the strike, but the force was enough to break his grip.
Roderick stepped in without hesitation, reaching to restrain him, but the student ducked low and pivoted, slipping past the attempt with surprising control.
"…He's trained," Thalia said, already moving.
She didn't rush in blindly. Instead, she adjusted her position, stepping into his path rather than chasing him. Her stance shifted just enough to cut off his forward movement, forcing him to choose another direction.
He reacted quickly, changing course—but that was exactly what she expected.
"Left," Thalia said.
Roderick moved instantly, closing that opening before it could be used. The student's options were shrinking, his movements becoming tighter as the space around him closed in.
Seraphine's voice came from behind, calm and analytical.
"His movements are efficient," she said. "He's not trying to win."
Alaric stepped forward again, this time more controlled.
"He's trying to reach something."
That was the key.
Sylwen's gaze shifted briefly toward the circuit.
"Don't let him get there," she said.
The student's eyes sharpened slightly at those words, his reaction subtle but unmistakable.
