The Conduit is a mystical place where one can speak with incorporeal voices said to be the voices of The Powers that Be. To get there, one must perform an advanced magic ritual, and the spell itself is extremely hard to find.
Once performed, the subject will be dropped into a mystical chamber, devoid of time and space. The conduit (currently the slain "Oracles" now incorporal) itself has no form and cannot be seen. The conduit also has the power of extreme telekinesis.
The conduit can kick a person out of this realm when ever they chose - it could be because they feel they are done talking with the person or they feel the person is unworthy to talk to them in the first place. Sometimes this very fact prevents the magic ritual from working.
