He showed up suddenly at the Vareth Magic Institute and soon became an assistant professor. No one knows much about his past, but he is in fact of the same race as Nyx. He has no conscience and feels no compunction about betraying or lying to others. A self-centered man who thinks only of his own career.
Although his race being listed as human in the friend book, Ardoph is in fact of the same race as the fearsome Nyx despite the fact that they don't necessarily look similar.
Some people believe Ardoph corresponds to Frankenstein's monster, just as Sonata corresponds to a werewolf, and Nyx to a vampire.
