Daomei (atys)
Jungle even more strict: must be Kamist and Zorai citizen (min Initiate, for higher service Awakened), more liberal admission granted previously by the theocracy of Leanon challenged and fought by Aniro Zorai.
I have to correct you on this, but first : what do you call nation RP ? If it is attending to the assembly and being able to speak, it is not so strict as you think.
Assemblies are not reserved to Zoraï kamist citizens, we of course accept ambassadors, but even anybody who come and sit down. (except marauders maybe)
Speaking may be a matter if something openly against Kami is said : hey, it's a Theocracy !
The fact that there have been rules to follow is not preventing peoples to participate.
If now you include the rights to "vote" , then yes, of course it's reserved to citizens, official citizens, that is Initiates. I put you in the challeng of finding an IRL land where foreigners have a voice to decide the future of the country.
This is just logical, as would say my hero Spock ... or Sheldon Cooper
