A Zemblan actor and filmmaker, Odon is King Charles’s most loyal ally in the palace. After the Zemblan revolution, he pretends to be a revolutionary so that he can stay close to King Charles and help relay messages between the King and his followers. Odon is instrumental to helping King Charles to flee Zembla; he plans various aspects of the King’s escape, transports him across the border, and even impersonates him to help throw the police off his trail. According to the novel’s index, Odon is an alias for Donald O’Donnell; indeed, Odon is Sylvia O’Donnell’s son, and he puts Charles in touch with his mother, who eases his transition to America by finding him a job at Wordsmith. After Odon and Charles flee Zembla, Odon moves to Paris to direct movies.
