Nice place to show N00b's when you're on a TP run. Be great if
MA made a proper big cave system there with a few specialised mobs or an underground city or something.
They were unique until the system under that stag/moose/whatever building in NO were discovered.
If you know the trick to climbing the chimney and getting on the top of the rock, I did leave something there a while ago...though someone may have found it now (or a mini-VU could have scrubbed it from the system).
