I plead the fifth
I've been wondering about this for some time now but how do you reckon Mewman nobility works? Because from what I understand Star is the princess of ALL of Mewni, and Moon and River are the absolute monarchs of Mewni, but there are still sub-kingdoms? Are those titles of "queen" and "king" (King Ponyhead, Queen Spiderbite, etc) just honorary and do they actually signify positions such as "count" or "duke"? Or is there information I'm missing?
