Papal Mainframe

The Papal Mainframe was an ecclesiastical leader whose authority gave Colonel Manton permission to lower the hoods on headless monks — an act that was otherwise a level one heresy. At the time Manton took the action at the asteroid Demon's Run, the Mainframe was either female or commonly referenced to with feminine pronouns. (DW: A Good Man Goes to War)

Being called a "mainframe", she was likely an artificial intelligence.
