the true antagonist= mother and Johannes

You can add the emperor too

well he is a cause of frustration but instead of an antagonist I consider him a stupid obstacle.. hes gonna die anyway he should just DO IT HAHAHAHAHAHAHAHAHA

I think he's more of an antagonist for Rebecca, since he's forcing her marriage, and pretty much the entire empire cause if he does give the throne to his dumbass of a son, than the empire is doomed to ruin
