The Dainty China Country and its ruler, the China Princess. In the Oz book series, Glinda has created all of these little kingdoms in the land of the south (a kingdom of rabbits, a paper doll kingdom, etc.) and so I imagine she created this kingdom as well. The wall of the country is made to look like ruins to keep people out (it’s also very tall), but the occasional traveler gets in.
I wanted it to be really idyllic and picturesque. The designs of the Princess and her handmaidens are inspired by Marie Antoinette and her friends.
