I was taking my sorc through the bridge district one rainy night, when i couldn't help but notice that door (you know the one, next to the entrance to the elemental lich, protected by the disintegrate trap and the message that says "this is dark, you would be foolish to enter" or something). Out of boredom/curiousity i went up and clicked on that door and, to my pleasant surprise, i am presented with a save game screen and whisked off to another plane where i wreak a little havoc and come back with a tasty little staff for my trouble.

My question is this: Is there anywhere else in Soa/ToB where a rogue stone, or something similar, is used to gain access to an area? If not for the fact that i just happened to have a rogue stone in my possession at the time, i would still be thinking that it was just another message from the designers to cover up a doorway/stairway/passage that they didn't have time to put something on the other side. It pisses me off that I had walked past there a hundred times and the only clue to there being anything more than a dark space was a single line in the RS description stating that it is used in the gem jump spell.

sorry for the long winded sentences. this has got me worked up.
