to a mirror world.  Weird Harold  00-00-0000, 00:00 AM  It is my theory that the pillar ter'angreal used to initiate Wise Ones and Clan Chiefs has an (in-built??) function to glimpse into a mirror world, the definition of which mirror world is determined by the identity of the user.  We know that going through the pillars reveals the genealogical history of the user - ancestor to ancestor, moving along the history line backwards.  Why would the Columns be constructed with two modes of operation. We know that the Columns showed an absolute past -- whether it followed threads or read the ancestry from the candidate's blood. In other words, there is absolutely no reason to believe that the original function had any connection to the Mirror Worlds, Worlds of If, Parallel Worlds or anything except the candidate's actual, absolute, ancestry.  Expecting a connection to mirror worlds or anything except the actual, absolute, bloodline of the candidate is like expecting your car to fly because you put the transmission in reverse.
