Born from Veyra's most cunning manipulation of the Arcane Fracture, the Echo Thief emerged when she discovered how to steal rather than simply shatter harmonic resonance. Forged in the moment she first turned a Harmonic Binder's own echo against them, it became her perfect instrument for corrupting order from within.

This spectral entity possesses the unique ability to infiltrate harmonic fields undetected, absorbing beneficial echoes and instantly corrupting them into chaotic frequencies. Its form shifts between translucent stealth and violent spectral flares, allowing it to move unseen through stabilized areas before striking. The stolen echoes become part of its essence, growing stronger with each theft while leaving behind only discordant silence.

The Echo Thief serves as Veyra's most strategic weapon, actively sabotaging the Harmonic Binders' restoration efforts by stealing their progress and converting it into fuel for further chaos. It represents the Fractureborn Echoes' evolution from simple destruction to sophisticated corruption.
