Your Grace, Your Highness, Your Eminence, Your Excellency, these are words that I often use to greet people who titled themselves in monarch when it comes to RP in any game.
But considering that I have not joined any faction, meeting 'Kings' such as Reinhardt, Trebor, or UGBERT without serving under them got me hesitant whether or not to use Your Highness whenever responding to them in-game, and calling out my King is just not appropriate for a freelancer, I suppose?
Just wondering, if any English gurus out there can clarify these for me I'd be grateful.
