@DeadWeatherDrums: no, you don't want to become its suzerain . be carefull to not achieve quests by mystake. this is basically the idea behind my "negative city-states" (I made several like this).

Good for military training.Thanks!

Forgive me for sounding dumb or insulting, but why would anyone want this in their empire?

Now if you say, "Well, Jon, it's a wildcard; you just might end up with it after enough random Quests are fulfilled," then I'd say, 'Oh, that's pretty cool. I like wildcard features.'

Alternatively I could see a feature where by its bonus is something like "Nations you are at war with suffer -15% Gold." Not that'd be worth spending Envoys on. Especially if you got the subtracted Gold.
