The Hero's Path

I understand everything now. Thanks again. I didn't touch the hero in the cave; he's too strong. So, I don't have any bugs, which is good. Question: As far as I know, in Heroes, magic wands with spells are charged in cities where mage guilds are built. But how do I charge wands with spells in this campaign, or is it not possible? And also, where can I find workers for the mine that I cleared of undead, using the method I was taught by the monks? Or should I just sell the mine?
