There's a lot of loose ends to tidy up. Of course they could just be an artifact of ad hoc writing - just starting up threads so they have something to do next week, then uh oh, the essential protagonist is killed for some unrelated reason. It's not a good way to tell a story.
In any case the Rus never invaded Norway so they're not even making historical fiction anymore. It's just a sword and sorcery soap opera.
The Rus were Swedish Vikings who travelled down the rivers of eastern Europe and built up a settlement at what became Kiev. I don't know why they have to make up fictional stories of these times as the historical events are quite entertaining.
