Dawn came slowly, like it wasn't sure it was allowed.
Caelith went to class anyway.
Routine made you blend in. Routine dulled the Codex's hunger.
But after last night, blending in was a story she could no longer sell.
Her name had been flagged.
Her steps would be watched.
──────────────────
The Trial Board in the main hall updated at breakfast.
Students lined up in front of it like it was a shrine.
They read their categories the way people read their fate.
Caelith didn't plan to look.
Her eyes did it anyway.
CAELITH DIANARA — CLASS NULL
No trial date.
No placement.
No explanation.
Just a label that should not exist.
Null wasn't a rank.
Null was what the Codex used when it couldn't compute something.
A placeholder. A warning. A box for the unboxable.
Liora appeared beside her fast.
"Don't stare," Liora whispered.
"I'm not staring," Caelith said.
Liora's tone was tight. "You are."
Caelith finally looked away.
Because Liora was right.
And because the board felt like it was looking back.

In Codex History, Professor Voss paced the amphitheater like he was trying to wear calm like armor.
He tapped his cane once.
One beat.
Then another.
Then another.
Echoes. Perfect. Clean.
"Echoes don't lie," Voss said.
His voice carried like a judge's verdict, but his eyes looked tired in a human way.
"Echoes remember laws even when we forget them," he continued. "So today we begin with something you are not supposed to recall."
Students activated their ledgers. Thin glyph screens floated above desks.
Seven beats.
Pause.
Seven beats.
Voss stopped at the front.
"Law 7.13.9," he said. "Recite it."
Only one hand rose.
Not Kael's.
Not Caelith's.
Liora's.
Her voice was steady.
"Law 7.13.9: No memory shall persist beyond approved harmonic frequency. Echoes that deviate must be silenced."
Voss gave a small smile.
It didn't reach his eyes.
"Correct."
He drew a sigil in the air—seven lines forming a heptagon.
It bled slightly at the corners, like the shape itself was tired.
"Now," Voss said, "what if an echo refuses silence?"
Caelith said nothing.
But her finger traced a hexagon on the edge of her desk.
Six sides.
Stop.
The room flickered—not lights-out, not dramatic. More like a camera losing focus for half a second.
Liora's head turned.
She watched Caelith's finger.
And for the first time, her expression sharpened in a way that wasn't just worry.
It was calculation.
In the corner, Ysa shifted in her seat.
Her ledger screen glitched.
For one blink, it showed a six-sided glyph.
Then corrected itself.
Ysa's curls shimmered, like her illusion almost failed.
Her reflection smiled a fraction too early.
Then everything snapped back to seven.
Caelith pretended she hadn't seen it.
Because seeing was dangerous.
And letting people know you saw was worse.
──────────────────
After class, the doors sealed behind them with a hiss.
The hallway felt wrong.
Not loud.
Just… pressed.
Like the air had been instructed to keep secrets.
Kael caught up to Caelith near the Reflection Wing.
"I know what it means," he said.
Caelith didn't look at him. "What does?"
"Class Null."
Her mouth twitched. Not a smile.
"You're a law the Codex doesn't recognize," Kael said. "It can't place you. It can't name you correctly."
Caelith stopped. "So I'm a flaw."
Kael stepped beside her. "No. You're a start."
Caelith glanced at him then. "And you?"
Kael didn't answer directly.
"My mirror wrote something last night," he said. "After you left."
He handed her a folded page. The ink was warm. The paper was cold, like it had been stored with a corpse.
Caelith unfolded it.
Six words. Handwritten.
My name is not what they kept.
Caelith looked up. "Your sister."
Kael nodded.
"She hummed six notes where seven were required," he said. "The Codex flagged her as defective. I forgot her name."
His voice cracked, just slightly.
"I didn't mean to," he added.
Caelith handed the page back without comment.
But her eyes stayed on the words longer than she meant to.
──────────────────
That night, Liora paced their dorm like a storm contained in skin.
"I don't trust Ysa," she muttered. "She watches Kael like she's memorizing him. Her ledger glitched today. I saw it."
"She's dangerous," Caelith said.
Liora stopped. Looked at her.
"She's not the only one," Liora said softly. "You've changed."
Caelith raised an eyebrow. "Have I?"
"You used to trace hexagons under the table," Liora said. "Now you do it in front of everyone."
Caelith's mouth tilted. "Maybe I'm starting a trend."
Liora flopped onto the bed in dramatic defeat. "Yes. Rebellion couture. Very you."
"I always had taste," Caelith said.
"In both fashion and treason," Liora replied.
Caelith looked at Liora—ink-stained fingers, messy braid, stubborn eyes—and something in her face softened.
"I'm not just a problem anymore," Caelith said quietly. "I'm an exception."
Liora sat up again. The humor faded.
"She doesn't fit either," Liora said. "Ysa. I think she's hiding something in the Spire Archives."
"Then we look," Caelith said.
Liora's voice dropped. "We're going to get erased, aren't we?"
Caelith didn't blink.
"Not if we get there first."
In the back of Caelith's mind, she thought she heard something—Liora's voice, but frayed, like it came through static:
Don't let them see you see.
Caelith's shadow twitched.
Just once.
──────────────────
In the hallway outside, a mirror flickered.
A glyph formed on its surface—seven lines trying to close a loop.
It failed.
At the center, a hexagon pulsed once.
Not erased.
Just remembered differently.
Haiku (5–7–5):
A law wants her boxed.
Six corners break the rhythm.
Mirrors learn new shapes.
