Leaders are, otherwise, similar to other Sims. They can be dueled/sparred with or even sent to the Pit of Judgement. A good relationship with these Sims will not affect the loyalty of the territories they command, although if befriended they will never decline to say what edict they are planning on voting for. Foreign leaders tend to make good marriage candidates for the monarch, as unlike many other characters they can always be found in or around the castle.
