The Void Disciple prestige class (Complete Divine) gains an ability called Sense Void as their primary class feature. This ability allows them to observe an "area, person, or thing" at a distance.
A previous GM ruled that if I used Sense Void to target a person or object, then I could sense that person or object, but not the things around it. For example, I could sense a genie's lamp, but I couldn't see the person that was carrying it.
Is my previous GM's interpretation correct? Can a Void Disciple using Sense Void not see anyone around the person or object they Sense?
