Hey so I was a mercenary captain for the Khuzaits for I'd say at least a month so I figured there wasn't a contract like Warband so I figured I could just go to a lord and absolve my mercenary contract. They asked me if I'm sure which I said yes. Then gave me dialogues for if I was leaving the faction as a vassal. I said yes to all of them then got -20 relations with everyone in the Khuzaits.
