Nirkhuz have designed a bunch of lists for playing Brytenwalda battles during the age of the viking raids.
This mod includes lists for Scandinavians (Danish, Swedish and Norwegians), Hiberno-Norses, and Orkeneyinga and kingdom of the isles.
All credits for Nirkhuz, who is also working on a Brytenwalda fantasy mod for Tolkien's Middle-Earth.
