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. He is well respected both inside and outside the prison, having been one of the few individuals to be given a noble title from the Palais Mermonia, something which is considered rare and a privilege in Fontanian society. Outside of his duties he enjoys tea. He used to be a prisoner.
