Born from the violent collision of a thousand shattered memories during the Arcane Fracture's initial eruption, the Splinter Daemon gained malevolent sentience by feeding on the concentrated trauma of forgotten experiences. Veyra discovered this writhing mass of corrupted recollections and bound it to her will, transforming it into her most effective weapon against harmonic stabilization.

The Splinter Daemon exists as a semi-corporeal entity of shifting spectral energy, its form constantly fragmenting and reforming as memories flow through its essence like liquid chaos. Its touch corrupts stable memories into jagged psychological weapons, while its presence causes reality to flicker between past and present, creating temporal distortions that prevent harmonic synthesis. The daemon can phase through solid matter but becomes substantial when engaging with memory-based phenomena, allowing it to physically manipulate and shatter organized recollections.

The Splinter Daemon serves as Veyra's primary hunter-killer, actively stalking courses where Harmonic Binders attempt to organize memories into stable patterns. It transforms successful recollections into fragmented nightmares that spread chaos through player experiences, ensuring that no memory remains pure enough to contribute to reality restoration.
