Hi, Rossco. Come check out Atravia and speak with Jarl Kaleva Värracht. While we're not straight up Norse or viking focused, we do take a lot of inspiration from Norse culture and lore, among others, such as Germanic, Slavic, etc. (with our own lore building flavor). Many of us in Atravia are rather history nerds and can geek out over these periods and areas with you.
Edit to note that no one attached to a kingdom currently can promise a certain biome or tribe until after domain selection, but we can share individual preferences. Neran is my first, Brudvir would come second for me above all the others by a good measure.
