purpose? it's a nice view. and perhaps something more was intended for it someday.
what is fun is playing around with a friend up there. it's hard to notice what the large sphere up top is for. if you take a friend there and play with the controls in the pyramid you can see what happens up top from outside, even from the roof.
my thoughts, like the teledahn stone, perhaps a relto page was meant to be found atop the kadish pyramid once upon a time. that stone isn't to be found in CC though. the teledahn stone is.
edit: @kaveman ya know, i think i've noticed that too! far too convienent to be happenstance. i wonder if the game can recognize when the word "bahro" is spoken. yes! i've heard screams after that word is uttered in chat as well! it always seem to occur durring the course of natural conversation, so i beleive the game is somehow tailored to make it appear that way. parlor tricks. makes me wonder about the inginuity of our wizards at cyan!
