A two-meter weighted chain with shaped striking links at both ends, constructed from case-hardened carbon-lattice steel. The Serpent is an ancient weapon type rebuilt with modern materials — each link is individually forged and case-hardened to resist deformation on impact, and the terminal striking weights are machined from solid Ablonite-KR ceramic for maximum impact damage and the material's characteristic thermal reaction against ferrous targets.

The Forge-Smith Collective's chain fighters represent one of GLMZ's oldest continuous martial traditions — chain fighting predates the city's corporate era and has been passed through community lineages for generations. The weapon's appeal is its versatility: it can strike, wrap, disarm, entangle, and control space. A skilled chain fighter in a corridor is a moving perimeter of steel that can engage threats from multiple angles simultaneously.

The Serpent's ceramic terminal weights add a modern edge to the traditional weapon. On impact with cybernetic components, the Ablonite-KR's reactive properties generate localized heating that damages sensitive electronics and causes pain responses in biological tissue adjacent to implant housings. Chain fighters have adapted their techniques to exploit this property, targeting the joints and connection points of augmented opponents where ceramic-on-metal contact causes maximum disruption.
