Original sentence: Charles IX's claim can thus be seen as "king of the Kvens",
Edited sentence: Again, the ethnicity of the kings is not directly discussed.Charles IX's claim can thus be seen as "king of the Kvens", that is, of Kvenland.Charles IX's use of it is seen as related to the construction of the Kajaani castle in 1604 close to Sweden-Finland's border with Russia.Despite the fact that the legendary title "King of Kvenland" appears widely used in various contexts, it is mentioned only once in that particular form/spelling in sagas:.For instance, according to Hversu Noregr byggðist the Kvens made sacrifices to Thorri.He also appears to have been a Kven himself.However, interpretations of their ethnicity have been made based on other information provided.This, along with similar pieces of information from other sources, has led many experts to believe that Thorri, who ruled over Kvenland, was himself of Kven origin as well.Unlike Egils saga, Orkneyinga saga does not provide clues about the ethnicity of Fornjót or any of his descendants
