The
Silver Mine is where you start your first expedition. There's not
much danger here, just a few rats and some skeletons. The skeletons
are easy to defeat if you know how to Turn them, but if not, they can still
be beaten by the tried and true method of whacking on their skulls with
an axe or two.
The
mine changes slightly some time after you clear it out. Jorax starts
mining it again and there will be Ork miners in there tapping a new vein
of silver. I had hoped that I could kill some of the miners or take
the silver (expecially after I killed Jorax and became chief) but as yet
they just brush me off : ).
