Mizha is a bit long overdue for a reality check, but there was no reason to be so blunt about it.  Sheesh.

Mizha and her sister Azhari are NOT princesses.  The Rethuii simply don't have words to describe non-royal nobility.  In fact, they only have words for royals because of old stories they pass down since the North is not a formal kingdom or anything.  The girls were RAISED like princesses and lived in a big house with many servants, but they weren't actually princesses.
