As the guttural resonance deepened, Zephyr reacted instantly, unleashing a torrent of brilliant orange light that solidified into a wide, shimmering barrier before the swirling vortex.
The Radiant Flow pulsed with a fierce protective energy, a defiant shield against the encroaching darkness.
"Now, Einar!" Lyra commanded, her white lightblade crackling with energy as she stood ready to support them.
Focusing all his will, Einar reached deep into his core, drawing upon the vast emptiness of the Void within him.
He channeled that raw absence, shaping it into a focused wave of pure nullification. With a surge of intent, he unleashed it at the heart of the swirling grey vortex.
The Void energy slammed into the nexus of Gorok's corruption. There was an immediate and violent reaction. The deep resonance screeched into a discordant wail, and the swirling grey vortex bucked and writhed as if struck by an invisible force.
Cracks of pure darkness erupted from the vortex, lashing out like whips.
Lyra's lightblade danced, deflecting the dark energy strikes that threatened to overwhelm Zephyr's barrier.
The air crackled with conflicting energies, the vibrant orange of the Radiant Flow battling the oppressive grey and black of the Void.
Einar maintained his focus, pouring more of his Void power into the vortex, feeling a strange resistance, as if Gorok's will was actively fighting back.
The ancient energy signature beneath the corruption pulsed erratically, reacting to the chaotic influx of Void energy.
Suddenly, the swirling grey began to dissipate, revealing a form within. It was immense, its shape vaguely serpentine, composed of pure, shimmering white light that pulsed with incredible power.
Sealed within layers of intricate, energy-woven chains that seemed to be dissolving under the impact of Einar's Void energy, it had been the source of the ancient resonance.
But Gorok's influence was still present, tendrils of dark energy snaking around the luminous being, trying to maintain its hold.
The guttural resonance shifted into a piercing shriek of rage.
"The seal is weakening!" Lyra projected urgently.
"Gorok was trying to corrupt it! Einar, Zephyr, we need to sever the connection completely!"
Zephyr, pushing his Radiant Flow to its absolute limit, reinforced his barrier as more violent bursts of dark energy erupted from the exposed being.
Einar, seeing the tendrils of darkness clinging to the white light, focused his Void energy with pinpoint accuracy, targeting each corrupted connection.
With a series of sharp, focused pulses, Einar's Void energy severed the last of Gorok's hold on the luminous being.
The shrieking stopped abruptly, replaced by a deep, resonant hum that echoed through the chamber, a pure, untainted sound of immense power.
The swirling grey vortex vanished completely, leaving only the radiant, serpentine form suspended within the dissolving remnants of its prison.
The heart of the Silent Labyrinth, long dormant, had begun to awaken.
