(Fire & Sword) Problem with oath

[Nuke316]

Hi guys,

I have a problem in Fire & Sword, it seems I am not able to give my oath to any of the kingdoms, even if they are friendly, I go to their king and there is no dialog option where I ask to join the kingdom... I had no problems getting into a kingdom in Warband and now I'm really confused lol.

I don't get it, is it because I have -1 honor? If yes, how can I get more honor?

Or do I need to do quests before?

Thanks for answering!
