Ok, I went ahead and added some stuff to the wiki, going with option #2:
Valhyr
Surtyr
Surtyr, the Ean colony, is also northern and cold and Viking, but volcanic. So it's like Iceland.
I like this because although the story of Valhyr is very cool and it seems like a great inspiration for adventures, it seems a little limited for use in PC backgrounds. You can be a refugee from there, but if you came originally forty years ago, you're kind of old. If you're one of the "born on the boats" types (which I called "Seaborn"), that's an interesting story but it seems like you'd be somewhat cut off from the Viking culture. And if you come directly from modern Valhyr, well then you're probably an insane berserker who kills everyone on site, probably not welcome in most parties.
Not to say that clever people won't be able to fit in some interesting backgrounds around that, but a straightforward "I was born in a Viking land and I'm basically a Viking" is kind of hard. You can do that easier with Surtyr, which though under serious threat from the gith war, has not completely fallen yet.
I haven't edited some of the character creation material yet, like to put in notes for goliaths and bladelings. I also haven't come up with backgrounds for these locations. Since those actually affect game rules, I assume they require a proposal?
