The sword's blade vibrated in his grip, the energy from the Core Fragment flowing through him like an unstoppable current. Echo's body shuddered with the strain as he unleashed the full might of his new power.
A beam of radiant energy erupted from the blade, cutting through the air with the force of a thousand storms. It collided with the descending Void Sovereign, the impact sending shockwaves that cracked the sky itself.
For a moment, Echo thought he saw something flicker within the shadowy form of the Sovereign—something alive.
But the Void Sovereign did not waver. Instead, it absorbed the energy with terrifying ease. The beam of light vanished into the entity's form as if it were nothing more than mist, and the Sovereign's voice filled the air once more, colder and more monstrous than before.
"Your light is fleeting, Echo. I am eternal."
