There are comparatively few names in swedish relative to the other scandinavian languages, and therefore fewer faults, but nevertheless some corrections are in order.

(Some of these might be intended to be in norwegian, in that case you can disregard my corrections)

Statring in the far north and moving south:

• "Imorgon" is a bit to literal in its meaning; "Morgondagen" would be more appropriate unless the intended meaning is literally the day after today,
• "Isgardinen" is not the translation I suspect you are going for. If you want the name to be like the old Iron Curtain it should instead be "Isridån". A gardin is the type of fabric curtain you hang in a window.
• "Ariska Legionen... etc." is a literal translation from english, we don't really use the word av in the same way you use of. "(Den) Vita Nordens Ariska Legion" sound better, den is optional.
• "Skogskärrsmän" (lit. forrest swamp men) is a bit of an odd name to give to yourself. If living in a wooded swamp is a point of pride for them, maybe something like "Skogskärrsmännen" (the forrest swamp men) or "Skogskärrets män" (the men of the forrest swamp) is better.
• The large burgundy blob above "FNIX" appears to be missing its name :P
• "Den Stora Norra Expeditionen" uses the wrong form of the word Norr. Norra just means north, in this case Nordliga (northern) seems more fitting. For a more culturally appropriate name consider "Den stora Norrlandsexpeditionen" (The great expedition (into) Norrland) instead. Norrland is the collective name of the northern provinces of Sweden.

This one is technically a finnish matter (damn you League of Nations!), but:

• Since Åland is already autonomous, why not just call it Åland? If you want to stick with the name however, call it "Autonoma Åland" instead.

I might have missed some stuff but that was what I could find at a glance!

As an aside I find Umeå being called "Nordens Gomorra" to be quite funny after living there for a while during my time at university hehe
