Vansell (full name Vansellostophossius) was Coordinator of the Celestial Intervention Agency. He was a determined person who did his utmost to keep Gallifrey in its position of power, and to maintain the Web of Time.

Biography
The First Doctor knew him at the Prydon Academy. He (supposedly) called Vansell by the nickname of 'Nosebung'. (BFA: Neverland) Vansell belonged to the Deca, a clique of young Time Lords and Ladies which included the Doctor and the Master. Like Ushas and Rallon, Vansell did well for himself and received his Rassilon Imprimatur before the Doctor. Vansell had already joined the CIA despite his youth and followed their orders to watch the Doctor closely. (PDA: Divided Loyalties)

Angered because he believed the Sixth Doctor had let the Nestene Consciousness escape destruction by the Time Lords, he set up his trial on Space Station Zenobia (PDA: Synthespians™) The jury would subsequently acquit the Doctor of the charges. (DW: The Ultimate Foe)

Vansell led a Gallifreyan Time Station on an expedition into the world of Anti-Time to find what he believed to be the body of the Time Lords' revered founder, Rassilon. He was possessed by anti-time energy, and attempted a coup over Madam President Romana. With her help, Vansell overcame the anti-time influence and trapped a group of Neverpeople (along with himself) inside the Time Station's temporal reactors. He and the Neverpeople were vapourized by the temporal energy of the reactors. (BFA: Neverland)

He was succeeded as coordinator of the CIA by Narvin. (BFG: Weapon of Choice)

Alternative versions
In an alternative timeline, he first tried warning the Doctor from enabling the Knights of Velyshaa to conquer Gallifrey, then when that failed, attempted to kill him. (BFA: The Sirens of Time)

In another alternative timeline, he was a lowly servant of the House of Heartshaven, Lady Romana's ancestral home, who was secretly in the employ of her son Antonin. (BFG: Reborn)
