Echoes on the Breeze

No destination is beyond the reach of the wind. With a simple prayer to the kami, you can send your words across the span of the Empire, whispering into the ear of anyone you need to send a message. The person must be someone you know, and the spell will establish a link between you two of you only as long as you concentrate. You may communicate with one another, although you only hear each other's voices as whispers. Both participants are instantly aware when the connection is forged, and either can end it at any point.
