Joanna (The Crusade)

Lady Joanna was the sister of Richard the Lionheart and King John. While she was in Palestine with Richard in 1190, she took Vicki Pallister under her protection. Richard tried to arrange a marriage between Saphadin and her to broker a peace between the English and Saladin's people, the Saracens. Joanna herself, however, refused it. (TV: The Crusade)

In March 1215, Kamelion impersonated her younger brother King John. (TV: The King's Demons)
