Well, if you look at it, in each game we've been destroying the towers one by one. We destroyed Red Mountain, we destroyed the Whit-Gold Tower (presumeable, but there's an alternate theory that the Avatar of Akatosh replaced the Amulet of Kings), and the Snow Tower is unkown as to what the Stone truly is. Some say it's the Thu'um itself, so as long as there are those that practice it (the Grey Beards) then it will stay intact. However, I don't think it was Paarthy because you have a choice to destroy him or not, therefore it wouldn't make good sense within lore to make him the Stone. The other running theory is Alduin is the stone, in which case we destroyed yet another tower! It would seem that if the Aldmeri want the towers destroyed, they just have to sit back and wait. . . we're doing it for them!

However, we've strayed dangerously off topic, we were discussing the joining of the Psijic Order. There are a few threads out there for the Towers, plus the talk page linked to the Wikia Article. I would ask that any further discussion be taken to one of those venues, or perhaps a new thread if you have new theories.
