I made a model edit that replaces the current Kharazan with the original (you know the one everyone likes to explore)! Anyhow the tower can only be acessed one way. Which I will link you the thread that explains the route to follow plus some additions. Also it is unlikely that someone will see you after all no one ever goes to the town of kharazan. Oh and I will link the speech2.mpq in my next post in this thread.
