They’re just interested in bear fighting as a violent pastime and a way to make some money. There’s nothing deeper to it than that, though you could of course make something up if you have a better idea.
Thanks! That's very helpful. My next question is: the 'd8 tributes' that are in The Giving Tree hex? I only see 6 options. Do you roll a d6 on this table d8 times, or is it just meant to say 'd6 tributes'? Also, there's no #2 on that list of options...
