Manifests as a form composed entirely of VHS tracking lines - horizontal bars that shift and corrupt like a bad signal. Emits a low-frequency hum like an old VCR motor. Appears as phosphor-glow patterns during tape playback. Leaves permanent magnetic residue as evidence of attendance on any substrate it touches.

The Magnetic Soul serves as the Chaintrix's ultimate witness - it preserves every attendance regardless of whether official recordings exist, making it impossible to deny presence even when official systems fail. It exists as an emergent phenomenon the system didn't intend, born from the accumulated weight of eliminated players refusing to be forgotten.
