Grimgor Ironhand, or as he is more commonly known "That fat dwarven bastard", is not very good with people. Although jovial and friendly, his quick wit and short temper tends to get him into almost as much trouble as his physical abilities get him out...
He doesn't speak about his family or home, and it's pretty obvious there's something dark he left behind in his past, and possibily at the bottom of every tankard of ale he agrees to drink.
