Royalty issue

For me the closeness of the Royal Family is still kind of strange.
I get used to the situation when a King or a Queen is a historical figure or… a character from a fairy tale.
Here on this island past time and fantasy mixed together, and this makes me wonder.
Because if there is the Queen it must be also a dragon somewhere here, no?
If there is a princess, who does her hair?
And what if the other princess is a tomboy?
