The lecture hall was already full when Luke arrived.
Not crowded—packed. Students leaned against the stone balustrades, perched on window ledges, and filled the aisles with restless energy. Conversations overlapped in low, brittle tones. When Luke stepped inside, the noise thinned—not into silence, but into something more deliberate.
Attention.
He took a seat near the back. No one sat beside him.
At the front, Professor Caldrin adjusted the lectern's sigil array with careful fingers. An old man, spine straight, eyes sharp enough to cut glass. His reputation preceded him: Foundations of Arcane Structure. The class most first-years failed. The class everyone pretended they understood.
Caldrin looked up.
His gaze paused on Luke for half a breath too long.
"Settle," the professor said.
The hall obeyed.
"Yesterday's assessment," Caldrin continued, voice level, "produced an irregularity. You will not discuss it."
A ripple of restrained disappointment passed through the room.
"You will," Caldrin added, "observe."
Luke felt it then—the ward. Not heavy. Not aggressive. A thin, precise constraint woven into the air like punctuation. It did not suppress mana. It annotated it.
Observation, Luke thought. Again.
Caldrin traced a simple diagram in the air. Lines formed, intersected, stabilized. "Magic," he said, "is not power. It is structure. Power is merely what structure permits."
A few students nodded. Others copied the diagram as if speed might substitute for understanding.
"Today," Caldrin said, "we review the First Constraint."
He snapped his fingers.
The diagram collapsed into a lattice—tight, elegant, familiar. A standard. The room's mana aligned to it instantly, compliant as a trained animal.
Luke did not flinch.
Caldrin's eyes flicked back to him.
"Mr. Ardentis," the professor said, conversationally, "tell me why the lattice holds."
Every head turned.
Luke measured the room—the ward's pressure, the lattice's assumptions, the watchers he could feel but not see. He chose the safest truth.
"Because it excludes alternatives."
A murmur spread.
Caldrin smiled, thin and pleased. "Correct. It defines acceptable behavior and rejects variance."
The word landed like a pin.
Caldrin gestured. "Demonstration. Ms. Frostveil."
Elowen stepped forward without hesitation. Her mana rose cleanly, slotting into the lattice with surgical precision. The construct brightened—stable, efficient, unimpeachable.
Applause followed. Earned.
Caldrin nodded. "Control."
He turned. "Mr. Ardentis. Observe."
Luke stood.
The ward tightened—not to restrain, but to record. He felt it indexing him, preparing margins for notes.
"Do not cast," Caldrin said. "Simply observe."
Luke looked at the lattice.
He did not touch it.
He listened.
The structure hummed with certainty, its rules confident, its exclusions absolute. Luke traced the edges—not with mana, but with attention—mapping where the lattice refused to look.
A quiet ache formed behind his eyes.
It'sincomplete, he realized. Notwrong. Incomplete.
Caldrin's gaze sharpened. "You may sit."
Luke did.
The class exhaled as one.
Caldrin continued the lecture, but the rhythm had changed. Examples followed—clean, orthodox, unassailable. Yet every time the lattice appeared, Luke felt the ward's attention flicker toward him, as if asking a question it could not phrase.
At the break, students surged toward Elowen. Questions. Admiration. Relief.
Luke remained seated.
A voice cut through the noise. "You didn't even try."
Luke looked up. A tall student stood before him, crest pinned to his collar—upper cohort. Confident. Curious in the way predators were curious.
"I was told not to," Luke said.
The student smirked. "Or you couldn't."
Luke considered the lattice again. "If I had," he said evenly, "it wouldn't have helped."
The smirk faded. "What's that supposed to mean?"
"It would have changed the room," Luke replied. "And you wouldn't like how."
Silence pooled between them.
The student scoffed and walked away, laughter following him like cover.
Elowen approached once the crowd thinned. "You felt the ward," she said quietly.
"Yes."
"They're calibrating," she added. "Today was a baseline."
Luke nodded. "They're waiting for deviation."
Elowen studied him. "Don't give it to them."
"I won't," Luke said. Then, after a pause, "Not yet."
The bell rang.
As the hall emptied, Caldrin lingered by the lectern. "Mr. Ardentis," he said, without looking up. "You will submit a written analysis tonight."
"On the lattice?" Luke asked.
"On what it prevents," Caldrin replied.
Luke felt a smile threaten and pushed it down.
A written analysis, he realized. Words lasted longer than spells—and did more damage when read by the wrong people.
"Yes, Professor."
Caldrin finally met his eyes. There was no hostility there. Only interest.
"Be precise," the professor said. "Imprecision is how accidents happen."
Luke inclined his head.
As he left, the ward loosened—just enough to confirm it had been watching the entire time.
Observation, Luke thought, steady now.
They wanted to see how he would behave inside their definitions.
That was fine.
He had learned where the margins were.
