I could do without the three prologues tbh or having just one would be the best. 3 is overkill.
Knight or Duchess... such a tough choice buuutt Duchess. lol At a time where power is important and a title gives that to you, I think it's smarter to take the title. BUUT if she is to end up with Aquila, that title would be better off with the bro when she marries as to keep the title within the family.
