I have been pondering but I can't see a reason. She is half djinn/demon and her appearance is very expensive of that fact yet she only has the king trait as extra.
Could A knowledgeable lore enthusiast enlighten me ?
For Europa I think I could understand in term of technicality. I believe she was considered a princess not a ruler per say. For Marie Antoinette I really don't know either. In her type moon description they say that she reigned during where monarchy was no longer absolute. It might be that the king trait relate to the essence of ruling over titles?
Nevermind it's actually simpler. You need to be the ruler to qualify for that title. Marie Antoinette was the spouse of the ruler, not the ruler itself.
