I had a guy named Dharg The War-Bringer, was a crossbow guy who had this really creepy laugh. He never spoke. He just laughed and screamed. I bet he killed me 5 or 6 times because he was only really vulnerable to stealth but was always surrounded by followers. I finally killed him last night by ambushing his recruitment drive and shooting him a few times. Then the guys he was trying to recruit ganged up on him and massacred him and his crew. God, I hope he doesn't come back.
