If you were going to hide where best than to do it than right in front of the tower? And I will never trust the speaker as I have never seen his face! Nor does his tone sit well with me. Plus he's condescending. Also with most evil doers they spend hours working on ways with which to execute their evil plan, and what a better place to do this than the area he occupies most. I mean come on seriously and these ghosts are simply a way to control us. At least all guardians have the decency to take their helms of when at the tower!
