Also in terms of the other 3.

Mistlands I don't think so. Ground cover is kind of insane.
Ashlands people have found metal and some stuff in code for it.
Far North I don't believe anyone found anything to mine there either. If that is the last one we may need to bring everything with us.

So in the end out of 8 it may be 4 and 4
Right now 3 of 5 need a pickax
