I rather enjoy the story where Odin is hung from the world tree, and pierced with his own spear, so that he can gain the knowledge of the runes, and use them to possess power within the various realms.
I enjoy Norse mythology for varying reasons. One, because I am Norweigan. Two, too many people picture all the Norse gods running around with hammers and leather skirts, drinking all the time. I just like to expand the view a little. There are so many fascinating stories.
