Talker

A talker is an orc who serves to transmit long-distance messages as a kind of living telephone. Blindfolded and gagged, talkers are bound to a set of wires connected to a series of intermediary towers in which, presumably, are located other talkers who continue the message to the next tower(s) until the message's final destination. Talkers are used by Beard and the Orctzar to communicate with one another (or at least, for the former to report to the latter).
