He is probably plotting to steal her away and make her the pricess or smthing so the royal blood can yield the sacred sword or shit like that to make the Kalisto Dukedom lose power and stuff
That makes sense. Though I feel like they just want to create a scandal against the Kalisto. The duke's action to save her was not entirely against the law, but really improper for someone of nobel birth. So if she were proven to not be a Kalisto, the duke will lose face and might affect the power/influence of the dukedom. Vice versa, if she was proven as a Kalisto, people will talk about it. Thus, increasing their popularity that can later on increase the dukedom's influence.
But still, the emperor, himself, is involved. Based on how they sabotaged the results, it makes me think that they're making a huge deal out of it just to maximize the potential lost and damage to the dukedom :C
These bitches, really.. :C
It's kind of pathetic how the fucking emperor sides with the count and gets involve in such a 'small' matter (I meaaan, come on, he's an emperor so there should be more important things to work on right). Does he not have anything better to do??? He looks like shit and acts like shit to. CAN WE HAVE SOMEONE TO ASSASSINATE THE EMPEROR PLEASE? I reallyyy really wanna stab him a million times uwu
