From the shadow of the mysterious person I think he is
Spoiler!
The Emperor since he is the villain. When Camilla was already back home, she attends the Emperor's birthday banquet and she got shocked when she saw the Emperor, because there are many ghost behind him, and the ghost isn't normal because they only bowed their head and didn't react even when MC's ghost friend try to interact with them. The Emperor right now is actually only one soul who keeps to continue living throughout decades by transferring his soul to his descendant that is the next emperor.
Even Dorman and Havel can't do anything about ot because they don't know the real name of the soul possessing Emperor and it's been 500 years since that person is possessing people.
