The Division (or simply Division) was a shadowy rogue Time Lord organisation from Gallifrey who believed they could "guide and shape events" across space and time as they saw fit, directly contraventing the official policy of the Time Lords "strict non-interference" and evaded them by existing "outside one universe and on the cusp of many more" (TV: Survivors of the Flux)

By the Thirteenth Doctor's time, with Gallifrey gone, (TV: The Timeless Children) the only known surviving operative was Karvanista, (TV: The Halloween Apocalypse) who had fought alongside the Fugitive Doctor. (TV: Once, Upon Time) However, the Division was still very much active, (TV: Village of the Angels) and had begun a plan to destroy the universe in response to the Doctor learning about them. (TV: Survivors of the Flux)


Early history[]

"For Services To The Division" (TV: The Timeless Children)

Officially, the Division did not exist nor had operatives, and its history was mostly redacted from the Matrix. (TV: The Timeless Children) The Division began on Gallifrey, but outgrew the Time Lords after they swore a policy of non-intervention and sought to control the universe. (TV: Survivors of the Flux)

An early incarnation of the Doctor, during their period as the Timeless Child, was contacted, tested and recruited into the Division by Solpado. (TV: The Timeless Children) During her service to the Division, the Fugitive Doctor was sent alongside Karvanista and two other Division agents to capture Swarm and Azure at the Temple of Atropos. This was the Siege of Atropos, in which the Time Lords' structure for Time was restored.

In the aftermath, Swarm was successfully imprisoned. (TV: Once, Upon Time) He was kept on the Burnished Rage battleground, with Division agents visiting once every thousand years to check he was secure. En Sentac was an agent who served on many of these tours. (TV: The Halloween Apocalypse)

The Fugitive Doctor at some point tried to escape from service to the Division, hiding out on Earth under a Chameleon Arch to avoid detection. Division agent Gat employed a troop of Judoon to capture her. They traced the Doctor to Gloucester in 2020, but the Doctor tricked Gat into shooting herself, and escaped in her TARDIS. (TV: Fugitive of the Judoon)

Eventually, the Division thanked the Doctor for their service, then wiped their memory. (TV: The Timeless Children)

Thirteenth Doctor's discoveries[]

The Thirteenth Doctor first encountered the Division when she became embroiled in the Judoon hired to find her fugitive incarnation in Gloucester. Witnessing her younger self, whom she had no memory of, escape from Gat, the Doctor was left disturbed by the experience. (TV: Fugitive of the Judoon)

Digging deep into the Matrix, the Spy Master discovered the history of the Timeless Child including the Division. He found a fictional story of Brendan masking hidden data in the Matrix, with one of the clues to the truth was that the carriage clock he was given upon his retirement was dedicated for "services to the Division" instead of the Garda. He broadcast the story to the Thirteenth Doctor's mind, (TV: The Timeless Children) as she was battling Ashad's Cybermen. After she reached the Boundary, (TV: Ascension of the Cybermen) the Master linked it to the ruins of Gallifrey and forced the Doctor to come with him. There he used the Matrix to show her true history, including her cinnection to the Division. (TV: The Timeless Children)

Shortly after she learnt the truth, a Judoon cold case unit transmatted inside the Thirteenth Doctor's TARDIS and imprisoned her inside a maximum security facility for her crimes against the Division, (TV: The Timeless Children) as well as 7000 other crimes, though she ultimately escaped with the aid of Jack Harkness. (TV: Revolution of the Daleks)

The Doctor sought out Karvanista for information on the organisation, as he was the only surviving Division agent she could find. Karvanista refused to answer her questions and kept setting traps to get rid of her. (TV: The Halloween Apocalypse)

Destroying the universe[]

The Division, by now led by Tecteun, decided to abandon the universe for the next one, instigating a plan to destroy the universe, (TV: Survivors of the Flux) by releasing the Flux in space and the Ravagers, Swarm and Azure, in time. (TV: Once, Upon Time)

En Sentac served her final tour, checking Swarm was secure in his containment chamber. Swarm found his opportunity to breach the chamber, and killed her, allowing him to regenerate into a new form. Swarm then freed his sister, (TV: The Halloween Apocalypse) and they proceeded to overtake the Temple of Atropos once more, (TV: War of the Sontarans) triggering the Great Disruption. At the heart of the time storm, the Thirteenth Doctor relived the original siege within her time stream, providing some answers to her questions. After she restored the Mouri and repaired time, Tecteun contacted the Doctor to warn her off further attempts to stop the inevitable end of the universe. (TV: Once, Upon Time)

After one Weeping Angel went rogue with knowledge of the Division's entire history, an Extraction Squad of Angels was sent to retrieve it. The rogue Angel made a deal to hand over the Thirteenth Doctor to the squad instead, with her being recalled to the Division. (TV: Village of the Angels) The Doctor was brought to Tecteun who revealed the Division's plan and that the Doctor learning the truth had been a cause of their actions. She tempted the Doctor with a Chameleon Arch containing her erased memories, however the Doctor vowed to destroy the Division and save the universe. Swarm and Azure interrupted the confrontation, revealing they'd made a psycho-temporal bridge to reach the Division, and killed Tecteun. (TV: Survivors of the Flux)
