There should be a prequel game to the series that follows Ragnar Lothbrok. In the game we should see a young Ubba, Ivarr, and Bjorn as well as the other kings from his time like Aella and a young Aelfred who hopes that Ragnar would help him with the order. To make it interesting, make Ragnar a sage, which in turns explains his motivations for coming to England and knowing the past, present and possible future yet he has no idea till near the end of his life. Pretty cool too if he had actually met Eivor’s Parents long before the events of AC Valhalla.
