okay i have a long answer, if you're at all interested haha
my characters were originally in a nordic setting too, and I half-picked it for the meaning, but they've since been transplanted into a modern post-apoc fantasy setting but as it goes with their backstory, they've picked their own names (or her brother's picked their names) and a name that means 'always' is absolutely perfect for what he'd name her. (Mikael, however, is derived from Michael which means 'one who is like god', which sums up his total narcissism perfectly)
so this is a really extreme example of me picking names based on what they mean hahaa
and now after my mass of comments, recapping the current word - uselessgoddess has picked: altar
