What's the origin of this name, I know that one of its first appearances where in the book "The Five Songs of King Wulfharth," but why was he called this?
-He wasn't a hybrid, that's pretty much impossible since you always take the race of your mother.
----Was his father an Orsimer?
-Was it only a title that the Nords gave him because of his strength/ferocity? <- Most likely IMO
-Did he have bad teeth?
