Its my opinion (Just my opinion), that Odin was a lover of legends. He seems to both create the heroes’ obstacles and patron of heroes. He also seems to hold a particular favor towards language and poetry, which was used to tell stories. Also, he is a god of magic, and I’ve tended to think that magic draws from the creative process as literature. So above all, Odin could be a representative of the right hemisphere of the brain.
Today, I’d think Odin would expand his interests to all forms of media within the fantasy genre. Anything that can be used to tell stories of heroism, Odin would enjoy. I believe he’d have an affinity for games in particular, like mtg or dnd, where not only can stories be told but players can interact with the story.
Odin was a ruler, but he was also a breaker of social norms. I’d believe he wouldn’t enjoy traditionalists among modern day heathens. He’d much rather seek new and innovative traditions, practices, and avenues for magick. He may ask to be followed outside the Norse pantheon as simply a god of magic, creativity, and story telling. He’d come in the form of a jovial old man, perhaps working in a game store or comic shop. He’d encourage the innovative spirit of who ever he comes across, perhaps even to rebel a bit from whatever stifles their creativity.
