Ion Fortuna (イオン・フォルトゥナ) is the Earl of Memphis. He is a Methuselah of a high-ranking Imperial noble family and a favorite of the Empress. In the novels, it was stated that he has been appointed Chief Imperial Sword Bearer, and has been promised a future post in the State Secrets Institution. In the series, he was first introduced as a secret envoy sent by Empress Augusta Vradica to Cardinal Caterina Sforza. He is rather young and feminine in appearance, but is actually about the same age as his "tovarisch" and distant relative, Radu Barvon.
