I've got my eyes on grabbing a chunk of vaegirs for myself, but to do so alone would be suicide. So I devised the ingenious plot to help a couple claimants take their thrones first, establishing concrete allies. But then I found you have to swear fealty? Wtf? My contingecny is to worrk mercenary in several countries, using chivalry to win hearts and minds of those I defeat, but this isn't my preferred method. Are there any other ways?
