I'm also a puppet. Remember that you can't join the World Assembly with 2 nations at once, but you can remove your main nation from the WA and put your puppet in for you.
"Puppet" simply means that two or more different accounts are owned by the same person. You can play this game with many accounts, but you cannot use puppets to join the World Assembly ("WA multiing") or sidestep forum/telegram/RMB bans.
