Royalty in your setting

Who sits on the throne? And are the PCs ever likely to be in a room with them?

Where might they fit in a big show of pageantry like a coronation or jubilee? Part of the ceremony itself or the show around it, in the massed ranks, in the crowd, holding up placards and being moved on by police?

(Call back to the Star Wars RPG adverts pointing out an extra in a key scene and asking “What’s this guy’s story?” To which the answer is whether we care. But here I’m thinking established characters dealing with some big event.)
