"Near, far, wherever you are..." - Lyrics from the popular Tauren bard, Celine Dioff.
No matter the distance you can sense the presence of a specific person in the world. This person needs to have gone to the Eyes of the Gods at the same time as you, and the effect goes both ways. No matter the illusion you both have the ability to sense each other's whereabouts to an exact margin regardless of distance.
(As of the writing of this notation there is no known way to remove this effect.)
