Location: Gaia HQ – War Room
The grand hall hummed with tension. Flickering holograms displayed the spreading instability in Sector 17, where the echoes of a recent Abyss incursion continued to distort space. Though the breach had been sealed, faint frequencies lingered—ones only a Sound Knight could interpret.
Thea Synthesis 0 stood at the head of the table, arms folded, eyes sharp. "We need a specialist. These resonant anomalies aren't naturally decaying."
Her gaze turned to Sylvia.
"You once told me the world speaks in vibrations. What is it saying now?"
Sylvia's fingers traced Orisha's glimmering edges. "It's not speaking, Commander. It's… humming. Like something's waiting for a response."
Cyg, seated at the corner console, tapped keys quickly. "Data confirms faint sonic distortions. Echoes forming patterns—but not random."
"Or musical," Sylvia added. "They're harmonizing into something. It's not Abyss. It's… old."
"Ancient frequency?" Irene Synthesis 3 asked from across the room.
"A resonance predating the Gaia Grid," Sylvia said, rising. "If it's responding to Orisha's frequency, I have to go in."
Thea nodded. "Very well. You lead this operation. Take Cyg and Mia with you."
"Wait—Mia?" Sylvia blinked.
"Her Creation Force can stabilize harmonic fields. If something within is trying to rebuild, she can aid the process."
Mia, who had been quietly doodling notes on her grimoire beside Elaine, looked up and smiled sweetly.
"Yay~ I get to go on a resonance adventure!"
Sylvia chuckled, but her fingers clenched slightly. She liked Mia. A lot. But there was something about Mia's closeness to Cyg lately…
Location: Sector 17 – Ruins of the Harmonic Crypt
The trio descended into a shattered dome of crystalline ruins. The moment they entered, the air grew thick—like sound itself had weight.
Cyg scanned the walls. "Old sonic runes. Pre-Gaia dialect. Same structure from your Bell Cathedral training."
"This was a Resonant Sanctum," Sylvia whispered, running her hands along the engraved etchings. "Velan once spoke of it… but I thought it was lost."
Suddenly, the floor beneath them vibrated. A pulse, like a heartbeat, echoed through the chamber. Sylvia's earrings flared, resonating not in defense—but in harmony.
"It's calling me," she said.
"I can hear it too," Mia murmured, holding her grimoire close. "But it feels… sad."
"Stand back," Sylvia said, stepping into the sanctum's heart.
She raised Orisha, letting the frequency flow through her. Waves of past emotions flooded her senses—love, hope, despair, and betrayal.
Then, a voice—Velan's—echoed faintly.
"Sylvia… if you've come this far… then you're ready."
A burst of harmonic light shattered the chamber's illusions. The echo revealed a preserved relic—The Harmonic Core, once sealed by Velan himself.
"It's his final composition," she breathed.
"And probably encrypted," Cyg noted. "Like a locked symphony."
Sylvia stepped forward, and without hesitation, began to sing. Not a chant, not a battle cry—just a soft melody. The same lullaby Velan taught her long ago. The Core responded. Glowed.
"She's syncing," Mia said, eyes wide.
Orisha burst into pure white sound, engulfing Sylvia. For a brief moment, her body lifted, her soul merging with the song.
Sylvia's Mindscape – Inside the Harmonic Core
She stood in a world of endless strings and notes, each connected like a vast, living instrument.
Velan's spirit appeared—not a ghost, but an echo.
"I knew you'd find this place," he said gently.
"Why did you seal this away?" she asked.
"Because the world wasn't ready to listen. But you are. The Divine Symphony lies not in power—but in understanding all voices."
Sylvia reached out—and Orisha transformed. Sleek bands of sonic light wrapped around her body, harmonizing with her armor.
Divine Assimilation Unlocked: Orisha – Resonantia LuxAbility Gained: Ethereal Chorus – allows manipulation of emotional frequency to heal, strengthen, or disarm targets through sonic resonance.
Location: Sector 17 – Return to Reality
Sylvia gasped as she landed. The crystal ruins pulsed with vibrant light. The harmonic field stabilized.
Cyg knelt beside her. "Pulse rates normal. You did it."
"We did it," she whispered, smiling weakly.
Mia clapped softly. "That was beautiful."
"Velan... he left me his final symphony."
Sylvia stood shakily, then turned to Cyg.
"You've always heard my silence, even when I tried to bury it."
She paused.
"So hear this too."
And before Cyg could speak, she kissed him—gently, but undeniably.
Mia's eyes widened slightly but didn't speak. Instead, she turned away, her hands tightening around Lexigra.

Shadow stared at a waveform projection.
"The Song of Resonance has begun."
"Let it play," Erebus said darkly. "We'll write the final verse."
