Thanks. I was going to put something in that the babie's cries were disrupting the legion, and that's why they were playing nice, but this seemed... better.
He clairifies that the elf tortured his daughter at one point. The elf just cut her really bad, didn't sink to that level, but hurting a man's daughter is generally lethal once dad finds out. Regardless of how you go about doing the hurting.
I wouldn't call it a fight. A young dark elf noble with no combat training vs a grizzled veteran dwarf guild lord is going to be one sided no matter how you look at it. He wasn't fighting him, he was expressing a point, before removing the threat to his family permanently.
