Humanoid Card #0724 from the XMAQUINA Genesis Collection. SILK-XIII draws steady power from its reinforced iron core, endurance at 67 providing the longest operational window among Iron SILK units. The porcelain has cracked along the sternum where the core hums, and the silk cable wraps have stiffened, but the power still flows. Special Ability: IRON CORE. Reinforced power cell for sustained operation.
