Celestial Preservation Agency
From Tardis Wiki, the free Doctor Who reference
The Celestial Preservation Agency was an organisation consisting of Time Lords from the future. Their mandate was ensuring that history as well as its perception remained under control.
The CPA was responsible for ensuring that the Fifth Doctor's inadvertent extermination of the Scintillians was never revealed, as he was perceived as a great hero in their timeline. (AUDIO: Omega)
