I've been playing the Swedish version since it released and it is one of the few role playing games I really enjoy and it is all because of absolutely immaculate artwork from bonner and specifically from tapia.
And exactly like you I can't contain myself until thus release, that is how hyped I am!
Why don't you translate "lyktgubbe" to something like lanternwisp or lanternimp, maybe even go so far to actually call them for what they are "will-o-wisp?
