Circle of Thought
When these rings are forged, a ritual prepares the molten metal itself, forming a link between a set of rings. At least two must be made at once, and they are often produced in sets of three or four. A command word activates each ring, and allows the wearer of a ring to transmit his thoughts to the other ringbearers until deactivated, as the spell telepathic bond. Any message sent is sent to all active rings in the set, and distance is no object (although they do not allow interplanar communication). Of course, if you happen to find a pair of these rings, it’s possible that there are others in the set that you don’t know about — in which case someone could be listening in on your mental conversations.
