Yeah, in Norse mythology, they are only mentioned briefly. They never really do anything in the myths. The only time I heard anything about them were in descriptions of how the different worlds were created. The regular elves lived in Alfheim, next door to Asgard, and there were dark elves who lived underground in Svartalfaheim. At least I think that was underground, around where the dwarves lived. I never read any stories about what the elves were like, or what they did. But that's not too surprising, since it's kind of hard to find Norse myths in writing anywhere. Very cool correlary though: Gandalf is actually old Norse for "magic elf". I always thought that was neat. Although that was the name of one of the dwarves in Norse mythology. I have no idea why they would have named a dwarf 'magic elf'.
