You are the Prince or Princess of a nation or a kingdom. You are one of the most influential person there is. If you ever need to make a check within the limits of your Kingdom, you get advantage and a +3 on all charisma ability checks and saving throws. If you are a Prince/Princess of a nation this doesn't take effect if you're talking to an Emperor/Empress. If you are of a Kingdom the Duke/Duchess and King/Queen are also exempted.
