Council Police
From Tardis Wiki, the free Doctor Who reference
The Council Police was the organisation responsible for security and law enforcement on Gallifrey during the time of the Pythia. They kept the peace during the celebration of the return of Prydonius and, later, the unrest against the Pythia. (NA: Cat's Cradle: Time's Crucible)
- The Council Police presumably evolved into, or was the basis for, the Chancellery Guard.
