Restraint Muzzle Vest

The Restraint Muzzle Vest debuts in Iron Gold as a brutal two-part restraint device, combining a head muzzle with crawling metal fingers and an expanding rubber tongue-pin to silence and immobilize captives, while an inflating plastic vest hardens into dark polymer armor that pins arms to the chest. This sinister invention exemplifies the saga's escalating technological oppression in the Society's arsenal, marking a chilling evolution in crowd control and prisoner management amid the escalating war between Golds and their foes. Though appearing only in the fourth book, it underscores the series' progression toward ever more dehumanizing tools of dominance.
