I am getting sick of all the NPCs showing up just to check on how I am doing. I ran into FOUR in one room. To make matters worse, characters like Brother TShober have about 5-6 screens of preparation dialogue before you can tell them to go away. How badly will I screw myself if I just start killing these guys for some peace and quiet?

Kill them. NPCs of that race might be less friendly to you (and their enemies more friendly) but it's worth ending the suffering.

I like the way you think. I'm killing Brother Tshober first. It shouldn't take him long to show up again...
