They have a sadistic and morbid personality. The dungeons, that they have kept secret from others, is filled with vivisection and dissection tables, cages to hold patients in, and a pit to throw the bodies when they are no longer useful. They aren't above torture, and note that they don't need a reason for torture because what they do stems from a love for science and that they take a pride in their work. They are fascinated by the plague, and are sad to see it is gone. Kyan notices their eyes shine with a fell glee when they talk about corpses. They are the most independent of the courtiers and refuse to listen to Countess Nadia and Volta multiple times.
