I envision Cedeira’s culture as, essentially, Theme Park Germanic Medieval Europe with some actual historical tidbits. It’d be more accurate to say that it’s analogous to northern half of Europe in general (including northeastern), but dominated by a minority of quasi-Anglo-Saxon elite from northern Cedeira.
(That is, they’re concentrated in northern Cedeira now. Originally, they weren’t from there at all; their ancestors lived in what is now central Marelia, and were driven out first by dragons, and later by dryads and Elentians.)
One of the things I did to underscore the association was to use Anglo-Saxon or Anglo-Saxon-inspired names for the Cedeiran characters, usually with an eye to meaning. So, the children of the Poldan family:
Ormod: sad, despairing, hopeless
One of these is not like the others.
