The following days flowed with quiet precision. The Fangs of Shadow had settled into routine—morning training, afternoon drills, night patrols. For the rest of Insomnia, the peace felt ordinary. For them, it was the calm between missions, the brief stillness before another shadow stirred.
Inside the Citadel's lower training hall, the air shimmered faintly from heat and magitek residue. Four figures moved across the floor in synchronized rhythm—silent, focused, relentless. The hum of energy blended with the dull echo of boots and the whisper of steel slicing air.
Sirius Blake stood at the center, the black katana and the Leonis heirloom crossing in his hands, both blades still humming from the previous strike. Sweat dripped down his temple, caught in the pale glow of the training lights. Around him, Kael, Rhea, and Darius reset their stances, waiting for his next signal.
This was no ordinary spar. It was synchronization training—a combat drill designed not to test strength, but timing. Cor Leonis had called it "the heartbeat test." Sirius called it "breathing in rhythm."
Every motion had to flow like a shared pulse—attack, defense, evasion, all executed in harmony.
Failure wasn't punished by wounds, but by the silence that followed when one motion lagged behind the rest.
And failure was something Sirius no longer tolerated.

"Again," Sirius said quietly.
Kael groaned, wiping sweat from his jaw with the back of his arm. "You're actually trying to kill us this time."
Rhea shot him a sidelong glance. "At least it's not daemons doing it."
"Yet," Kael muttered.
"Focus," Sirius said, voice calm but sharp enough to slice the tension. "Formation Delta. No talking, no hesitation. Move with intent."
Darius cracked his knuckles once, the faint hum of his gauntlets sparking. "Understood."
Rhea took a breath and centered herself, the faint shimmer of aether gathering around her hands. Kael twirled his daggers once, rolling his shoulders, his grin a mask for fatigue.
Sirius lowered his blades into stance. The moment the tips aligned, the others followed instinctively.
"Begin."
---
The floor erupted with motion.
Kael struck first—fast and erratic, a blur of silver arcs and shadowed momentum. Darius intercepted, absorbing impact with sheer mass and converting defense into counter. Rhea weaved between them, illusions flickering at the edge of their strikes, bending angles and light to confuse their rhythm.
Sirius moved through them like a current—no wasted motion, no noise. His black katana clashed with Kael's knives in bursts of dark light, his silver blade sweeping through Rhea's mirrored illusions without disturbing a single projection.
The clang of weapons echoed in quick succession. The rhythm was close—almost perfect—until Kael overextended, cutting through an illusion that wasn't real.
The formation broke apart instantly.
Sirius caught Darius's punch with the flat of his sword, redirected it, and stepped back, breathing steady.
"Reset," he said softly.
Kael scowled. "You know, you could say something like, 'Nice try,' or 'Good effort,' once in a while."
"I could," Sirius said, lowering his blades. "But it wouldn't be true."
Rhea laughed despite her exhaustion. "He's learning sarcasm. That's new."
Darius simply rolled his shoulders again. "Ready when you are."
---
They tried again.
And again.
The training stretched into hours, broken only by the faint crackle of magitek energy cooling along the walls. Sweat pooled beneath their feet. Every mistake echoed louder in the silence than any sound of combat.
But each attempt brought improvement.
Kael's movements grew sharper, less reactive.
Rhea's illusions shifted seamlessly between offense and defense.
Darius's strikes became smoother, precise rather than brute.
And Sirius—he began to feel the rhythm between them, the invisible thread tying their motions together.
When they faltered, he adjusted with them, letting their rhythm dictate his own.
He wasn't their superior in that moment—he was their center.
Cor had once told him: "A commander who stands above his soldiers commands their fear. A commander who stands with them commands their faith."
He understood now.

Above the dome, Cor Leonis and Crowe Altius watched from the observation deck. The faint reflection of the training lights danced across the glass.
Crowe tilted her head slightly. "They're getting faster."
Cor grunted. "And quieter."
Crowe smirked. "That's high praise coming from you."
"They've stopped fighting the rhythm," Cor said. "They're listening to it."
Crowe's eyes flicked toward Sirius below. "He's changed. He moves different now. Not like a boy copying his mentor—more like a man building his own style."
Cor's gaze softened briefly. "He's learning the difference between leading and carrying."
Below, the clang of synchronized strikes rang out once—perfect, unified. The four moved as one entity: shadow, steel, and silence.
Crowe's smirk widened. "You think he's ready for a real mission?"
Cor's eyes didn't leave the field. "He's already leading one."
---
Sirius stopped the exercise with a raised hand. The others froze mid-motion, panting, sweat gleaming against the low light.
Kael dropped to one knee, gasping. "We… getting close?"
"Closer," Sirius said.
Rhea brushed back her hair, strands sticking to her cheek. "You know, I think I'm starting to hate that word."
"Good," Sirius replied. "That means you'll remember it."
Darius leaned against the wall, catching his breath. "You always this relentless?"
"Only when I care about the outcome."
Kael smirked faintly. "He's definitely Cor's nephew."
---
They resumed one final time.
And this time—it worked.
Kael's knives moved first, crossing paths with Rhea's mirrored illusions. Darius struck through one reflection, the real blow meeting Sirius's blade and glancing off harmlessly.
Rhea adjusted her timing, shifting her illusions to match their movements, creating overlapping echoes of light and shadow that danced like smoke around them.
Sirius moved within their pattern, guiding the flow with barely perceptible gestures.
When Kael struck, Darius blocked.
When Darius advanced, Rhea covered the blind spots.
Every motion built into another.
Four different fighting styles. One rhythm.
When the final strike landed—a coordinated assault that sent shockwaves through the chamber—they all stopped in the same heartbeat.
Silence.
No hesitation.
No imbalance.
Just stillness and the faint hum of four synchronized heartbeats.
---
Cor nodded once from above. "That's it."
Crowe folded her arms, eyes gleaming with pride. "Took them long enough."
"It's never about speed," Cor said quietly. "It's about trust."
Below, Sirius looked at his team. Kael was grinning through exhaustion. Rhea leaned on her knees, laughing breathlessly. Darius stood steady but allowed himself the faintest smile.
Sirius exhaled, lowering both blades. "Well done."
Kael blinked. "Did you just—"
"Yes," Sirius interrupted.
Rhea grinned. "Mark the date. He complimented us."
Darius's tone was deadpan. "End of the world confirmed."
Sirius shook his head. "Get cleaned up. We start again at dawn."
Kael groaned. "There it is."
---
That evening, they stood together on the Citadel's terrace. The wind was cool, the city lights painting their faces in pale glow.
Rhea leaned against the railing. "You ever think about what happens after all this?"
Kael shrugged. "We keep fighting. Or we finally sleep."
Darius said nothing for a long time, then murmured, "Maybe both."
Sirius rested his hands on the rail, eyes following the faint shimmer of the barrier above. "If we do our job right, maybe no one else ever has to fight the way we do."
Kael smirked. "That sounds like something Cor would say."
Sirius didn't deny it. "Maybe he's finally right."
---
They stood there, four shadows beneath a city of light, wind tugging softly at their cloaks. No words followed, no speeches or vows. They didn't need them anymore.
Their rhythm didn't live in orders or commands—it lived in trust.
For the first time since their formation, Sirius realized the truth Cor had known all along:
The Fangs of Shadow weren't defined by silence or secrecy.
They were defined by the quiet bond that made them whole.
