I wonder what skills we would use if we chose to bluff/intimidate?

I tend to agree that we should stick to things we've already learned here and try to finance our way out of this. Keep in mind that our funds are not unlimited and millionaire-princess Bruce Wayne would be better-trained by now, sadly. I am concerned that offering money for a section of land we're not familiar with will do two things: Overvalue the land (to our detriment) and set a precedent that the kingdom is full of appeaseniks who can be intimidated into emptying the treasury at even the slightest hint of resistance.
