The gold torc is a ring-shaped necklace or torc with gold plating manufactured for use by the Tanu and their favored, trusted human cohorts. When properly integrated with Tanu or human mind, it can raise previously latent metapsychic ability to operant equivalency. However, once worn and integrated, removing the torc can cause irreparable psychic damage and madness.
Unlike the silver torc, it has no control circuitry. A properly trained gold torc wearer can communicate metaspychically with (limited farspeech/telepathy), exert control over, or give pleasure stimulation to a wearer of a silver or gray torc.
There are no known instances of a firvulag adapting to or wearing a gold torc.
