I was asked to present some Finnish graphic novels for this community, and I think I cant go amiss by starting with the "grand old man" of finnish graphic novels/fantasy comics, Petri Hiltunen.
1) Hiltunen has been active since the 1980's and is perhaps most known for his Praedor fantasy world and the graphic novels, novels and ttrpg set into it.
2) Also he has done some adaptations of historic characters and fiction, like adapting Shakespeares MacBeth and ancient greek historian Xenophons work Anabasis.
3) Another good example of his style is 'trollpunk' albums with Ontot Kukkulat (Hollow Hills) in the 90's and Troll Patrol (with Tuomas Myllylä) in the 2020's.
4) He has also done a lot of strip comics for Finnish newspapers, depicting the observations of wizard Väinämöinen (from our national epic Kalevala) about modern Finnish society.
He has also done many, many more albums on different subjects and historical periods.
I'm not sure how many of his albums have been translated, but I think you can find at least some of the Praedor's and MacBeth in english.
Sorry for the poor quality images. Finn's do a lot things well and in interesting ways, but marketing themselves is not one of them. That or my search engine voodoo was not good enough.
