Two reasons why I didn't block the mithril mines.
 * 1) When I burnt their farmland, instead of putting out the fires or foraging them legitimately, they would instead drag away burning objects. They also took the opportunity of me not having a bluesteel spear to take back the castle they gave me. To put it bluntly, they were not the most honourable people, and would have seatglitched through or something. Perhaps used some of the gunpowder they foraged when I was lighting it.
 * 2) So sail to several far apart islands, make some medieval walls, then place them into position in their hard to reach entrances? You clearly do not know me, I am far to lazy for that. I only made bluesteel because I had most of the ingredients on me.
