The air in the Citadel's training hall was still that morning, unnaturally quiet. The usual hum of aether circuits and clashing steel was absent. Only the low, rhythmic pulse of the barrier above could be heard — steady, constant, like a slow heartbeat marking time.
Sirius stood at the center of the polished floor, his black coat half-buttoned, the Leonis heirloom resting against his back, the black katana at his hip. His reflection shimmered faintly beneath his boots, warped by the traces of residual magic left from the previous day's drills.
His team — Kael, Rhea, and Darius — stood in formation before him. Each looked sharp, focused, and silent, though Kael's eyes carried the familiar spark of impatience.
They had been summoned here by Cor Leonis himself, which meant this wasn't another drill. The Immortal didn't make appearances unless something — or someone — important was about to happen.

The heavy door slid open behind them, magitek servos hissing.
Cor entered first, his coat trailing faintly in his wake, the air seeming to bend around his presence.
Behind him walked a woman Sirius had never seen before.
Her steps were light but measured. Her hair, a deep shade of violet streaked with silver, was tied in a short braid that brushed against the polished collar of her uniform. The insignia of the Kingsglaive glimmered faintly on her chest — modified, blackened, and trimmed with gold. Her posture was disciplined, her eyes calm, yet there was a faint tension there — a readiness that reminded Sirius of himself years ago.
"Commander Blake," Cor said, his gravel voice breaking the silence. "Stand easy."
Sirius nodded. "Sir."
Cor's gaze swept the four of them. "You've come far. The missions in Leide and Cleigne proved that much. You move like soldiers — no, like a single organism. That's why it's time to expand the unit."
Rhea raised a brow. "Expand?"
Cor stepped aside, gesturing toward the newcomer. "This is Lyra Aurion. Kingsglaive operative, reassigned to the Shadow Guard by order of His Majesty."
The name struck faint recognition. Aurion. The same family line as Ignis Scientia — royal advisors and scholars of light magic.
Lyra stepped forward, boots echoing softly against the floor. When she stopped in front of Sirius, she removed one glove and knelt on one knee, head bowed.
Her voice, when she spoke, was clear and firm.
"Commander Sirius Blake. I am Lyra Aurion, formerly of the Kingsglaive. I am here to serve under your command, and to uphold the creed of Lucis."
Sirius blinked, caught slightly off guard. He wasn't used to people kneeling before him — not like this, not with reverence.
"You don't need to—" he began.
Cor's tone cut through his hesitation. "She does."
Sirius paused, then looked back down at Lyra. Her expression was unreadable, but her gaze held steady when she finally looked up.
"Then rise," he said quietly. "From today forward, we walk together — unseen, but not unbound."
---
Lyra rose smoothly, meeting his gaze. "Understood, Commander."
Kael leaned slightly toward Rhea, whispering, "Great. Another one who actually listens to him."
Rhea elbowed him in the ribs. "Try it sometime."
Cor's sharp glance silenced them both. "Aurion's transfer wasn't arbitrary," he said. "Her skills with long-range aetheric control and firearms are unmatched in the Kingsglaive. The King wanted someone who could balance your unit's rhythm. You're blunt instruments, all of you. She's refinement."
Kael grinned. "So she's the one who makes us look less like animals?"
Darius folded his arms. "She'll have her work cut out for her."
Rhea sighed, muttering, "We're doomed."
Sirius suppressed a faint smirk before returning his gaze to Cor. "What's her assignment?"
"She'll act as both marksman and recon. Her orders come from you."
"Understood."
Cor's eyes lingered on Sirius for a long moment. "You've earned my trust, Blake. Don't make me regret giving you command."
Then he turned to Lyra. "Welcome to the shadows, Aurion. They bite, but they're loyal."
"Yes, sir," Lyra said.
Cor gave a curt nod and left the hall, the door sliding shut behind him with a final, metallic click.
---
Silence returned.
For a moment, no one moved. The faint hum of magitek energy was the only sound.
Then Kael stepped forward, flashing Lyra a grin. "So, the Kingsglaive sends us their best? Hope you can keep up. We don't exactly move at a courtly pace."
Lyra didn't blink. "Then I'll run faster."
Rhea snorted, folding her arms. "You might actually survive here."
Darius, ever the quiet observer, nodded once. "We'll see in training."
Sirius watched their exchange quietly. There was always a strange moment when soldiers from different worlds collided — the disciplined precision of the Kingsglaive meeting the unpredictable fluidity of the Shadow Guard. But something in Lyra's bearing told him she could adapt.
"Kael," Sirius said. "Show her the firing range."
Kael blinked. "Already?"
"She's one of us now. She trains as one of us."
Lyra nodded. "Permission to use live ammunition?"
Sirius gave a small, approving tilt of his head. "Granted."
Kael sighed. "Oh, this'll be fun."
---
Hours later, the range echoed with the sound of thunder.
Kael and Rhea stood behind cover, watching as Lyra emptied a full mag of enchanted rounds across the field. Her shots pierced every illusion target Rhea conjured, each bullet striking the heart of a phantom before it vanished.
Kael's jaw dropped. "Did you just—"
"Sixteen for sixteen," Rhea muttered, impressed. "At full illusion drift. I can't even see those when they fade."
Lyra holstered her weapon and exhaled softly, magic threads fading from her fingertips. "I trained for precision, not for spectacle."
Kael whistled. "You just redefined both."
From the observation platform, Sirius watched in silence. Her control over the aether's flow was subtle but exact — no waste, no hesitation. Every strike was efficient, perfectly synchronized with her breathing.
She fights with restraint, he thought. The way I used to wish I could.
---
When training ended, Lyra approached him, posture formal.
"Permission to speak freely, Commander?"
"Granted."
"I've heard stories about the White Fang," she said. "About the boy who rose through the Guard faster than any in its history. I didn't believe them until now."
Sirius's tone stayed calm. "Believe what you see, not what you hear."
She nodded. "Then what I see is someone who carries more than his share of weight. I won't let you carry mine."
He met her gaze, and for a heartbeat, the air between them seemed to hum with unspoken understanding.
"Welcome to the Fangs," he said simply.
Lyra smiled faintly. "Gladly, Commander."
---
That night, as the five of them stood on the terrace, the lights of Insomnia stretching endlessly beneath them, Kael grinned wide.
"So we're five now, huh? What's next — a name? A crest? Maybe uniforms that don't smell like daemon guts?"
Rhea rolled her eyes. "You'd ruin any crest we get."
Lyra chuckled softly. "I'd suggest something simpler — one word."
Darius crossed his arms. "Like what?"
"Unity," she said.
Sirius looked out toward the barrier, its glow reflected in his crimson eyes. "Not bad," he murmured.
Then, more to himself than to them, he whispered,
> "Five shadows. One heartbeat."
The others didn't hear him, but the wind carried the words across the terrace — a quiet omen of what they would become.
Beneath the shimmering barrier of Lucis, five figures stood together for the first time — bound not by blood or oath, but by purpose.
The Guard of four had become five.
And from that night forward, the shadows no longer whispered of one Fang — but five.
