Celestial Intervention Agency

Celestial Intervention Agency, usually referred to as the CIA, are the Gallifreyan equivalent of spies who "don't even know which side they're on." (BFA: Gallifrey). They evolved from a core group of Rassilon's guards. (NA: Lungbarrow)

The CIA were a group created to be a covert arm of the High Council to safeguard the Time Lords' interests. (DW: Shada)

CIA's involvment in the universe
The CIA would routinely use others to do their bidding in the universe (both knowingly and unknowingly). They 'recruited' the Doctor in his third incarnation during his exile on the planet Earth. The first time, they sent him to Uxarieus to prevent the Master from obtaining the Doomsday Weapon. (DW: Colony in Space) The second time, they sent him to Peladon to assist in its joining the Galactic Federation. (DW: The Curse of Peladon) Following this, he was sent to Solos in Earth's future to deliver a package from the Time Lords. (DW: The Mutants)

It was a Time Lord by the name of Lord Ferain who appeared to the Doctor to send him on a mission to Skaro to avert the creation of the Daleks. It is believed that this was also one of the pre-emptive salvos of the Time War. (NA: Lungbarrow, DW: Genesis of the Daleks)

Following this (semi-successful) mission the Doctor was sent to Karn to prevent ex-Gallifreyan president Morbius from being ressurected and returned to body by Dr. Mehendri Solon. (DW: The Brain of Morbius)

The CIA sent a Time Lord as their agent to Apertsu to serve as a security consultant; however, he was captured by Aubertides who wanted the secret of regeneration. (NA: Human Nature)

CIA involvement on Gallifrey (and its affairs)
to be added (BFG: Gallifrey (audio series))

Leadership

 * Sentris was head of the CIA for a time before discovering how many people she had sent to the Oubliette of Eternity. Upon discovering the number, she threw herself into it. (BFA: Neverland)


 * Coordinator Vansell was head of the CIA during Romana's presidency until he encountered the Neverpeople. (BFA: Neverland)


 * Coordinator Narvin took over as head of the CIA following Vansell's death aboard the time station.

CIA Assets

 * Space Station Zenobia (the location of the Sixth Doctor's trial) was the property of the CIA. (EDA: The Eight Doctors)


 * Oubliette of Eternity a device which was supposed to remove people from history, but instead made them Neverpeople. (BFA: Neverland)

CIA Experiments

 * The CIA began to fear the number of temporally active races, so they began experimenting with various temporal technologies, including the TARDISes, in an attempt to move the minds of (newly created) TARDISes within the minds of aliens taken from over 50 planets. Time Lady Professor Klyst oversaw this experiment. (BFA: Unregenerate!)

The CIA and The War
President Romana sends CIA agents Gandarotethetledrax and Cavisadoratrelundar to observe/create the first Type 102 TARDIS (knowing that it will be a vital piece of technology in the upcoming war), and they witness the former Remote agent Compassion complete a transition to a sentient TARDIS, but are halted by the people of the Catuvalani. The Doctor escaped with the Type 102 TARDIS. (EDA: The Shadows of Avalon)

At some point in the lead-up to The War, the CIA became worried that they might be erased from history (or caught in the crossfire) between the Time Lords and The Enemy, and therefore created Mictlan, a world outside of time and the universe for themselves to hide within.

However, they also needed to remove themselves from the universe of physicality, and therefore turned themselves into The Celestis. (EDA: Alien Bodies, The Taking of Planet 5, Interference)
