Norse gods are fascinating, whenever You look through a book or a site about them, they are very vivid deities. They were very human-like in personality, with their tempers and jealousy.  And they would  appear, even if they were immortal, like a  crowd of Vikings, for the most part, which makes them different then Aztec and Egyptian gods where their gods were more animal than human. And plus, their immortality came from golden fruit, it wasn't born with them, which is very interesting, because this was a major weakness, because you could steal the fruit, and they would expire of old age.  These Gods are very interesting, because of their human-like tendencies, and their not-so humanlike qualities.
