Listen is a command to listen (or stop listening) to one of many communication channels.
In Game Description
Syntax: listen <channel> listen ravens listen wolves Listen is used to turn on and off the various player communication channels. To turn off a channel, listen to it again if it is already on. In addition to players, various mobs also communicate on the channels. For trollocs, crows/ravens/rats broadcast information, as do wolves on the human side (although only Wolfbrothers can hear the wolf reports). To turn off these mob reports, use listen ravens/wolves, depending upon your race. Example: > listen narrate > listen all > listen none > listen chat
