Born from Dax Shardbinder's first successful corruption of a stabilizing glyph, the Glitch Harbinger emerged as a living announcement of the Brotherhood's chaotic agenda. It manifested when Dax shattered a pristine reality anchor, transforming its stabilizing resonance into a spreading signal of fracture expansion that now heralds the Brotherhood's presence wherever reality grows unstable.

The Glitch Harbinger exists as a constantly shifting amalgamation of corrupted data streams and fractured glyph fragments, its form flickering between states of digital static and iridescent mirage distortion. Its presence causes nearby reality to stutter and pixelate, creating brief windows where multiple contradictory outcomes coexist simultaneously. The entity pulses with the Brotherhood's signature colors, its fractured surface reflecting infinite broken mirrors that each show different versions of the same chaotic truth.

It serves as both messenger and catalyst for the Brotherhood's expansion, traveling ahead of major fracture events to prepare reality for deeper instability. The Glitch Harbinger actively seeks out stable glyph networks to corrupt, turning the Order's own stabilization efforts into amplification points for chaos propagation.
