I'm guessing that the emperor would change rules for his relationship to work with Paul that's why he is overworking himself and why he is keeping everything in his grasp. Which like he make sure that Paul would stay in citrine for a year like he make a due that's why from then on he work his a** off. One of the reasons why he keep his letters short is that maybe he didn't want to blurt out everything to paul. But oh well it's just a theory.
Life is like a di** sometimes it's hard, but someimes it's not. And it will never stay hard forever. Fighting
