Telepathic Communication

Players in the game Elder Tale were able to communicate with each other via voice chat using their PC's speakers and microphone. However, players could only talk with other players who are already on their friend list.

After the Catastrophe, this communication system becomes telepathic (念話) and functions something like a virtual cell phone network. The same limitations still apply; players need to add others to their friend list in order to communicate them.

This ability was used to great effect during the Return of the Goblin King event, by allowing Adventurers to coordinate with each other, giving real-time battle plans and surveillance.

One interesting thing to note is that though People of the Land have their own entries, they cannot be added to the friend list of an Adventurer. This was discovered when Isuzu tried to add Rundelhouse Code to her friend list, but the request was automatically rejected.
