Graves are not _really_ all that terribly important, ya know. I am personally thrilled that that historic piece of engineering should come back to the ken of men after so many years. If the owner of that long decrepit skeleton was still hanging around there, worrying about his sad fate, why it was probably a favor to jar him out of his obsession so he could get on with more interesting work! It's not as though he hasn't had enough time to recover!
