Final Fantasy XII: Trapped in Pharos of Ridorana?

I can't get out :\ I;m at the end of the game but I'm doing all the hunts n stuff so I went there to do the Seer one and I realized I have no tel stones left, I tried going all the way back to the top (which took ages) but when I got to the way stone nothing happened and I can't go back 'cus its'just a dead end, wtf do I do?
