Bozjan lore is properly scuffed.

[Iscah]

For two, Radovan made it clear that he served the queen of Bozja within his lines throughout his introduction.

Having checked the first two quests, he says that he served as "personal guard to [his] queen" (not the queen of Bozja, just his queen), and then separately that his clan are "the descendants of Gunnhildr's royal guard". That still doesn't clear up the distinction of the different types of queens, but says nothing about Gunnhildr being a present queen. If anything it suggests that the tradition of a central Queen Gunnhildr may have been replaced by individual tribal queens, but we still have no clear answers on this.
