Narvin

Coordinator Narvin replaced Coordinator Vansell as head of the Celestial Intervention Agency following Vansell's death aboard the time station during the Anti-Time crisis.

Biography
Many centuries before becoming Coordinator, Narvin had been a technician working under Glower on Project Alpha - to develop a 'Timonic Fusion Device'. They were warned of dire consequences by then-Ambassador Braxiatel, but the two dismissed his theories and proceeded with the test. The resulting catastrophe destroyed an entire world, and necessitated the CIA to conceal the involvement of the Time Lords. Narvin took up a position in the agency not long afterwards and as Braxiatel put it, "never looked back." Narvin and Braxiatel harboured a long-standing enmity towards each other, possibly dating from this incident. (BFG: The Inquiry)

As Chief Coordinator, Narvin was originally against the Lady President Romana and her liberal reforms and drew the suspicions of the Castellan at the time, Andred. Correctly assuming that he was being drawn into a trap, he sent Torvald in his place when they agreed to meet, which cost Torvald his life and Andred a regeneration, though Narvin was unaware of this. Believing Andred to be Torvald, he quickly covered up the event to protect "Torvald", only admitting that he had done so when held at knife point by Leela and only discovering the truth after Andred's confession during the Cecelia Pollard incident on 3 September 1939. Narvin immediately felt a loathing for Andred, which he implied would not have been as strong if Andred had not killed one of his operatives. (BFG: The Inquiry, A Blind Eye, Lies)

After Romana's actions on Gryben, Narvin demanded an inquiry, but ultimately failed to get her arrested or charged. He eventually teamed with the Inquisitor Darkel in an attempt to remove her from her office, along with her supporters, one of whom was Braxiatel. Though Braxiatel took him into confidence by confessing that he was in frequent contact with past and future selves (a very serious crime), Narvin betrayed him, using the information to get Braxiatel dishonourably exiled and to puncture a hole in Romana's credibility. Unfortunately, misjudging the extent of Darkel's ambitions, his actions and his trust in her (despite the fact that she obviously felt very cavalier about the idea of him being arrested) ended up indirectly causing the release of Pandora and the resulting civil war that threw the entire planet into turmoil. (BFG: Insurgency) Narvin later admitted that he had made a mistake in betraying Braxiatel's trust. (BFG: Mindbomb)

At some point following Spirit, Narvin was involved in the development of the assassin Aesino, a being that had been fractured through time, which he (presumably along with other members of the CIA) had hooked up to the late-Castellan Wynter's TARDIS, or at the least the one he had stolen. He was unable to perfect it before war broke out, and never suggested it as a weapon, fearing what the Vault's consciousness would do if ever in the possession of a Time Lord President.

When Pandora was released and began to wreak havoc on Gallifrey, he joined Romana's side in the civil war and nearly regenerated (possibly for the first time) in a premature bomb explosion which also blinded Leela. After recovering and transporting into the Anomaly Vaults to save Romana, he managed to engineer Romana, Leela, Commander Hallan's and his own escape to now ruined remnants of the Academy. He helped build a stronghold there, creating his own adaptation of certain Matrix partitions, in effect a force field capable of keeping everything out. Through this technology, Romana was able to enter APC Net chamber and eventually defeat Pandora. (BFG: Fractures, Warfare

Though Narvin had started as a someone who would have liked nothing better to see Romana defamed, he ended up, somewhat unexpectedly, after the events of Free Time, Pandora, and Darkel's machinations (including planting a bug bomb into his shoulder that Leela had to cut out and dispose of), as one of the more staunch supporters of Romana and one of the few senior Time Lords who continued to do so after the civil war had ended. When Romana ultimately chose to sacrifice herself along with Pandora and the Matrix, Narvin was the only one who actively attempted to save her (as his President and as was his duty), as Matthias had accepted her decision and Elbon didn't care. He took great risks in keeping Romana informed and alive during the election proceeding the war and also did everything in his power to try and prevent Darkel from obtaining the Presidency, even going so far as to say that if she were ever elected, he would resign from his position.(BFG: Pandora, Warfare, Appropriation)

Narvin and Leela shared an association, partially through the status Leela held due to her husband Andred (Narvin believed for a time that he had covered up the murder of Andred by one of his C.I.A. agents) and through her friendship with Romana. Particularly during the civil war and after, with most of their other confidants either exiled or locked up or dead, Leela often (if a little reluctantly) went to him for advice, and Narvin often went to Leela for errands he couldn't trust to anyone else.

Later on, Narvin seemed extremely concerned for Romana's safety after she was stripped of her rank. (BFG: Series 4)
