My favorite is about this guy named Paul who carved out the great lakes for his ox, Babe.One of my favorite is the Chinese legend that there used to be ten Sun Raven, one for each hour of the day, but one day they all came at the same time, threatening to burn the world. A legendary archer then shot down 9 of them.
Paul Bunyan doesn't make a good model for D&D. Many mythical figures do not.
