The school building is not much bigger than it was originally.  It's mostly the shape that different.  The outdoor yards are gone, the tracks, the tennis, the baseball diamonds all subsumed into this eerie gray toned fortress.<br/><br/>Going around reveals that the outer wall is made from the outdoor halls that connected the original structures, but stretched upwards and connecting to four large towers.  And only one way in.<br/><br/>But that's not the creepiest part.  At no time does the moon ever move from 'behind' the castle, no matter what angle, no matter where one looks at it, it's still there.
