Born from Veyra's first deliberate corruption of a harmonic convergence, the Venom Echo emerged when she poisoned a stabilizing resonance with fragmented memory splinters. What began as a single corrupted note spread through the harmonic network, transforming every echo it touched into an agent of chaos. Now it serves as the Fractureborn Echoes' primary tool for infiltrating and corrupting the very foundations of reality's harmonic structure.

The Venom Echo exists as a semi-corporeal spectral entity that can phase through harmonic barriers and infiltrate resonance networks with ease. Its corrupting influence spreads through contact, transforming stable echoes into chaotic variants that actively work against harmonic restoration. Once it infects a harmonic structure, it creates a self-perpetuating cycle of corruption that's nearly impossible to cleanse without destroying the entire network. The entity feeds on the chaos it creates, growing stronger as it spreads its influence across multiple realms.

It serves as the Fractureborn Echoes' primary infiltration weapon, spreading corruption through harmonic networks to prevent reality stabilization. The Venom Echo actively hunts stable resonance patterns, poisoning them from within to create cascading failures that amplify existing fractures and generate new sources of chaos.
