The Interfering Nun

The Interfering Nun was a Time Lady who broke with the Gallifreyan tradition of inactivity. She was mentioned by Romana II in a conversation about renegade Time Lords. (PROSE: Shada)

When Zoe Heriot accused the Monk of changing history, he admitted it proudly, rhetorically asking if the Interfering Nun was responsible. (AUDIO: The Prints of Denmark)

Behind the scenes

 * The Interfering Nun is, of course, a joke on the part of author Gareth Roberts: a distaff equivalent of the Meddling Monk.
 * In Doom Coalition 3, River Song, who is part-Time Lord, and is disguised as a nun, is referred to by the Clocksmith as "the Interfering Nun". This is consistent with "the Meddling Monk" being a temporary disguise of another Time Lord.
 * Later, Doctor Who media would actually introduce a female incarnation of the Monk who indeed went by the name "the Nun".
