Finnish name for Germany is "Saksa" and the name for Austria is "Itävalta" (Itä = east, valta = power
) I don't know the person what you mentioned, but Oxenstierna is quite famous noble family from Sweden. I just googled that Erik Graf fellow and noticed that he has wrote some norse related book, but it have not published in here.
There is about 3600 people in my home municipality de.wikipedia.org/wiki/Rautj%C3…
but over half of the population live quite small area close to big paper mill where is also some schools, shops, library, church, health center, apartment buildings and so on.. Most of the 401.89 square kilometres area in this municipality are forests and fields and my house is located in much smaller countryside village called Änkilä about 8 kilometers from that "paper mill town" Simpele. There is some pictures from my farm in my scraps-section.
I know one youtuber from Austria called "Survival Lilly" and she has made a lot of outdoor videos where Lilly makes different things in the middle of woods. Your forest scenery look quite similar than in here, but we have more spruces and pines so the nordic forests are at least more dense than in your country.
