For the upgrade of shar and the dragon discussion I will respond next time (when I am on a real comp)
The souledge user was the old GM so he wont appear anymore

and the is a valid reason for the Guardian idea to not attack humans
2 even
One is the things hiden in these ruins are meant by legend for the humans
as humans dobt exist originally, the ones that would show up would be the rightfull owners/ hairs for the hidden stuff (if they would find it)
Second, the guardian would have to be immortal due ti the ages, so a golum would be a good option, but golums with a job like this needs to be 'programmed' and humans as a non existing presences would be a blind spot, something the golum would not even be able to see as a sentiant race
