The air in the Citadel was beginning to turn crisp, a herald of the approaching autumn. For Matthew, time had become a strange, distorted thing. Between the brutal midnight sessions with Lyra, the frantic late-night study marathons with Andrew, and the constant mechanical fine-tuning of his gear with Andre, weeks had slipped by like sand through his fingers.
But today, the Academy gates opened for a different reason. It was "Family Visitation Day"—a tradition designed to remind the students of the kingdom they were sworn to protect. For most, it meant noble carriages, fine silks, and political posturing. For Matthew, it was the first time he had been granted official leave to visit the Convent of the Silver Lily since the incident in the Whispering Woods.
"You're pacing again," Andrew said, leaning against the doorframe of Room 402. He was dressed in his formal Elite attire, waiting for his own parents to arrive. "She's going to be fine, Matt. You've sent her letters every week."
"Letters aren't the same as being there," Matthew muttered, adjusting the collar of his grey tunic. He checked the Aegis Dampers on his hands. They were hidden beneath a pair of ordinary-looking leather gloves, but he could feel the silver wiring humming against his skin.
"Take this," Andre said, popping up from under a pile of scrap metal. He handed Matthew a small, beautifully carved wooden box. "It's a music box. I infused it with a minor wind-core fragment. It plays a lullaby from the Southern Isles. It doesn't need mana to run—it works on a mechanical spring. Totally safe for her to have."
Matthew took the gift, a lump forming in his throat. "Thanks, Andre. Truly."
The Convent of the Silver Lily was a place of profound peace. White stone walls were draped in climbing jasmine, and the sound of a nearby waterfall provided a constant, soothing rhythm. As Matthew walked through the archway, he felt the heavy, suffocating pressure of the Academy's mana-veins begin to lift.
He saw her almost immediately.
Emily was sitting on a stone bench in the center of the garden, a sketchbook open on her lap. She looked smaller than he remembered, her blonde hair tied back with a simple blue ribbon. She was drawing a picture of a bird, her tongue poking out in concentration.
"Emily," he called out softly.
The girl froze. She looked up, her eyes wide, and then she let out a scream of pure joy that echoed off the white walls. She scrambled off the bench, her sketchbook fluttering to the grass, and sprinted toward him.
Matthew caught her, lifting her high into the air as she wrapped her arms around his neck. For a moment, he wasn't a Null, a weapon, or a student. He was just a brother.
"You're late!" she scolded, burying her face in his shoulder. "You said you'd be here when the lilies bloomed, and they've been out for three days!"
"I'm sorry, Em. The teachers... they had a lot of tests for me," Matthew said, setting her down but keeping his hands on her shoulders. He looked at her closely, checking for any sign of sadness or illness. She looked healthy, her cheeks pink from the sun.
They sat together on the bench, and Matthew presented Andre's music box. Emily's eyes lit up as the delicate melody began to play, the tiny mechanical gears whirring inside.
"It's beautiful, Matt," she whispered. "Is this what they teach you at the Academy? How to make pretty things?"
Matthew's smile wavered. "Some people learn that. I'm mostly learning how to... stay strong. So we can find a place of our own one day."
"The Sisters say you're going to be a hero," Emily said, looking at him with a sudden, piercing seriousness. "Like the ones in the stories. But sometimes... sometimes I have bad dreams. I dream about the fire in Oakhaven. I dream that the black smoke is coming back for us."
Matthew felt the violet spark in his chest thrum with a protective fury. He pulled her closer, his gloved hand resting gently on her head. "The smoke isn't coming back, Emily. I promise you. I'm going to make sure of it."
"But your eyes," she whispered, pulling back just enough to look at him. "They look different. They look like the sky before a thunderstorm."
Matthew froze. He hadn't realized the "bruised" violet ring around his pupils was visible in the bright sunlight. He forced a laugh, tucking her head back under his chin. "That's just the reflection of the Academy's magic, Em. It happens to everyone who studies there."
As they spent the afternoon together—drawing pictures, eating the honey cakes the Sisters had prepared, and walking through the shaded groves—Matthew realized how much he had changed. The peaceful world of the Convent felt fragile to him now. He looked at the white stone and saw how easily it could crumble. He looked at the Sisters and realized they had no defense against a Shadow-Stalker, let alone a Blight-Walker.
He realized that the 55 chapters of his life in the Academy weren't just about his own survival. They were about building a fortress around this little girl.
"Matthew?" Emily asked as the sun began to dip below the horizon, signaling the end of his leave.
"Yeah?"
"Don't become a hero if it means you have to leave me again," she said, clutching the music box to her chest. "I'd rather have a brother who is a Zero than a Hero I never see."
The words cut deeper than Lyra's sword ever could. Matthew knelt and kissed her forehead, his heart heavy with the weight of the secrets he was keeping.
"I'll always come back for you, Emily. No matter what."
As he walked back toward the looming spires of the Citadel, the peace of the garden was replaced by the cold, familiar hum of the Aegis Dampers. He saw the Elite carriages passing him by, the noble families laughing and celebrating their power.
He didn't hate them anymore. He just understood them. They fought for their legacies; he was fighting for a music box and a sketchbook.
And as the violet light in his eyes flared in the gathering dusk, he knew which one was stronger.
