#havent watched season 1 in a while

It really bothers me that we know so little about the other kingdoms in Etheria. Like Bright Moon has a Queen but have we ever heard of Kings/Queens in other kingdoms or are the rest of them all Princessipations? Principalities? And if so, who is in charge of Dryll since Entrapta moved to the Fright Zone? Like do any of the other princesses even have parents? I mean 11 year old Frosta was left to host the ball on her own, maybe because it’s a tradition specifically for princesses but it very much seemed like she was the ruling monarch. For that matter, what is Dryll even like when its citizens aren’t hiding from deranged robots? Did anyone else live in the castle besides Entrapta and her 3 kitchen staff (because presumably robots can’t make human food, based on season 3)? Give us more world building in season 4 please!
