Lady Franciezka was the headmistress of the spy network in Roldem and served King Carole of Roldem.
She has several sexual encounters with her counterpart in the Kingdom of the Isles, Jim Dasher, and plans to retire with him to some remote island, even though she has tried to kill him twice. She and Jim discover their love in the last book, Magician's End.
One of Lady Franciezka's main duties was protecting the Princess Stephané from being married to the son of Lord John Worthington, who sought to take over the governance of the Island of Roldem. She smuggled Stephané out of Roldem with the help of Hal and Ty. Eventually she gives up her post and lives with Jim.
