Composed of visible sound waves frozen in corrupted transmission data - the Canticle is literally visible as shimmering, broken waveforms that twist through the air. Changes pitch based on the competitor it appears to - higher, more discordant frequencies for those close to deletion; harmonious for those with stable code. Leaves crystalline residue wherever it manifests - tiny fragments of what appears to be frozen sound that dissolve within minutes. Cannot be captured or recorded - only experienced directly; recording devices only capture static.

The Void Canticle serves as the simulation's death announcer and final offering - it appears to competitors whose code is destabilizing to herald approaching deletion. Unlike the Static Herald's cold notifications, the Canticle offers a choice: face complete oblivion, or join its eternal chorus as a partially-rendered voice trapped between HD and null. This creates the ultimate moral tension in the deathmatch.
