At least no one turned full out into a cat. I'd rather stick to just fish people.
Emperor, huh? Those seem to be pretty popular here. I guess history is pretty regulated in your time?
Unfortunately there doesn't seem to be any history books at the library, or I'd point you that way, but that's probably for the better. Too many different universes around and all. I'd probably start to get confused if I was looking up something of my own but was really reading some other world's history where Hannibal never marched elephants over the Alps and Hitler stayed an artist. Though that could be interesting to read in itself.
You can probably track down some of the names in an encyclopedia or dictionary to learn a little bit though. Not much cultural context about the Norse, but you'd at least get to pick up a few things about them. Or maybe Acumen will loan you a nice big archive.
