Also known as "The Lord of Ruin", Ione is the granddaughter of Michael Saldana, once the Crown Prince of the Saldana Royal Family and creator of the Tranquillity habitat. The Saldanas had been staunch defenders of the Adamist culture for centuries, and Michael's betrayal caused a considerable scandal which led to the exile of himself and all of his descendants. Ione is the absolute ruler of Tranquillity, with complete dictatorial power over every aspect of life. She kept her presence on the habitat secret for some years, concerned that her youth and seeming inexperience would cause a crisis of confidence amongst the economic community if she revealed herself. Joshua Calvert is one of Ione's lovers and the father of her unborn children.
During the mission to locate the Sleeping God made by Oenone and the Lady Macbeth Ione placed personality copies of herself in the Serjeants that provided tactical support. The Serjeants she controlled later proved invaluable during the infiltration of Tanjuntic-RI
