Wriothesley is the "Duke" of the Fortress of Meropide, serving as the prison's administrator and overseeing the facility's overall status. Despite his appearance, Wriothesley is fairly calm and collected, not worrying too much about the prison's infamous reputation as he only sees himself as a "leader" of sorts to oversee the population and ensuring they have the "tranquility" they desire. He sees the prison as a place of rebirth and is willing to protect that way of life.
