An elf who ventures outside in winter has a lot of daring. Elf ears are very, very delicate, and the winter cold can really mess them up. So if you see an elf adventuring in winter, know that that particular elf is a really daring dude.
The amount of daring you'd need is about equal to the amount Genghis Khan (かん) had. And he was really daring!
