M&B: Warband - Do male husbands roam the map?
Solution 1:
Yes, husbands roam the map. As i was in the same faction as my husband i cannot tell you if you can fight against or with him.(I always fighted alongside with him).
Marriying will increases the relationship with all the relatives of your partner, it also increases your right to rule(but as you are trying to become a sole emperor that doesnt have any advantage).
