Im quite interested in the vikings too, its something I'd like to read up on more.
I always watch the documentry's when they are on but I think I might get a book or look elsewhere for more info.
Something interesting to add is when I was in Ireland I went over to a small island by boat on my own, there was an old church and barracks made of stone, about half of them left from the bottom up.
You can see marks the Vikings left there all those centuries ago on rocks, Im never that interested in anything academic but this is the sort of thing that makes me want to know more.
My favourite God is Loki, I dont know if he is considered a minor god?
