 These lesser torcs allow for control of the wearer by any gold torc wearer.Silver Torcs give operancy equal to that of the gold, but unlike the gold torc they also incorporate control circuitry.This allows a gold torc wearer to compel obedience in the silver torc wearer, allows for punishment or reward of the silver torc wearer via so-called pleasure-pain circuitry, and act as a means of mentally tracking the wearer.
