Papal Mainframe

The Papal Mainframe was an ecclesiastical leader on whose authority Colonel Manton lowered the hoods on headless monks — an act that was otherwise a level 1 heresy. At the time Manton took the action at Demons Run, the Mainframe was either actually female or commonly referred to with a feminine pronoun. (TV: A Good Man Goes to War)

• Following their return to their own time, Vastra and Jenny were added to the Papal Mainframe's "most wanted" list. (PROSE: The Brilliant Book 2012)
