From Ardrana

Mindlink allows the user to communicate wordlessly with any intelligent creature he can contact. This is two-way communication. It is not the same as mind-reading because the psionicist only receives thoughts which the other party wants to send. Language is not a barrier. Distance affects the telepath's ability to make contact, but it has no other effect.

Note: Mindlink originally appeared in this form in the Complete Psionicist's Handbook for the AD&D game from TSR. Its use here is for the purposes of providing context for the campaign only.
