Jolene (Excelis Dawns)

 was a nun of the Excelis convent. She felt that Iris Wildthyme was a disruptive influence to her and her fellow sisters. The Mother Superior tasked her with accompanying the party searching for the relic as an agent of the convent. She stole the map from the Fifth Doctor in a bid to claim the relic, but ultimately failed. (AUDIO: Excelis Dawns) In reality, she was a guise taken on by Snyder. (AUDIO: The Plague Herds of Excelis)
