Mylin,
As you are probably aware the entire building appears to have collapsed. We had started clean up efforts but over night the structure weakened - it was good no cleaning crews were there at the time.
We will need to rebuild from scratch and I have a coupleof ideas for warding the entries to prevent this kind of occurance happening again.
There is not much more that can be done except to clear and rebuild - mayhaps we could look at using some of the abandoned structures in Upper rather than rebuilding in lower.
I shall await your instructions, Chell
