Divergent
The Divergence or Divergents were a race of powerful creatures whom Rassilon sealed inside the Divergent Universe.
Biology
The Divergence were non-humanoid. (AUDIO: Zagreus [+]Loading...["Zagreus (audio story)"]) The Eighth Doctor was not sure whether they had fingers. (AUDIO: Caerdroia [+]Loading...["Caerdroia (audio story)"])
Society
The Divergence had their own language, but borrowed words from other languages when they wanted to describe something more subtly or more precisely than they could in their own. The Eighth Doctor and Charlotte Pollard doubted that they had much mercy. (AUDIO: Caerdroia [+]Loading...["Caerdroia (audio story)"])
Technology
The Kro'ka claimed that the Divergence were more technologically advanced than the Eighth Doctor could imagine and were in possession of methods of interrogation far more effective than a mind blast. (AUDIO: Caerdroia [+]Loading...["Caerdroia (audio story)"]) They were able to empower the animatronics of Winkle's Wonderland from the Divergent Universe (AUDIO: Zagreus [+]Loading...["Zagreus (audio story)"]) and turn Bortresoye into a crucible world to run experiments.

History
Imprisonment
The creatures which came to be known as the Divergence dated back to the birth of the universe. When Rassilon travelled to the end of the universe, he found that they had devoured and eliminated all life within 10,000 millennia of his own time and were capable of casting their own Web of Time which could encircle his. He did not know of their specifics of whether they were a species or a genus, but witnessed and feared their primal and elemental strength and ability to restructure all matter.
Rassilon released biogenic molecules to make the dominant life forms of 69,000 planets to make them resemble Gallifreyans and intended to allow all other life, including every Divergent, to die. The Divergence realised that Rassilon was changing the future and tried to stop him, but he trapped them at the end of the aborted timeline and sealed them within a pocket universe which he put in a Möbius loop, (AUDIO: Zagreus [+]Loading...["Zagreus (audio story)"]) creating a constant cycle of death and rebirth. (AUDIO: The Next Life [+]Loading...["The Next Life (audio story)"])
Escape attempts
Rassilon siphoned power off from the Divergent Universe to his foundry until he was challenged by the Committee of Three and stopped it, triggering the automatic firestorm to stop the Divergence escaping and killing the Committee. The Divergence were desperate for release and got a glimpse of the universe when Dr Stone and Reverend Matthew Townsend briefly opened a gash in space and time in 1951, but Townsend detonated a bomb and prevented them from escaping. They later empowered Goldilocks and the other animatronics at Winkle's Wonderland to damage or destroy the foundry's reality lock in a bid for freedom. This plan failed thanks to Walton Winkle.
The Divergent Universe was due to reopen at the end of the universe, so Rassilon made plans to infect the Eighth Doctor with anti-time and have him kill the Divergence with a dagger forged from the Doctor's TARDIS. Zagreus, the entity created when the Doctor was infected with anti-time, refused to be Rassilon's puppet and instead sent him through the opened door to the Divergence. (AUDIO: Zagreus [+]Loading...["Zagreus (audio story)"]) He remained in the universe for more than 84 cycles. (AUDIO: The Next Life [+]Loading...["The Next Life (audio story)"]) The Doctor was exiled to the Divergent Universe by Romana II and intended on making peace with the Divergence if it was possible.

Fading away
Please help by adding some more information.
The Divergence set themselves up as the dominant species of the Divergent Universe and set to work trying to break the cycle of death and rebirth. This included setting up a base of operations on the planet Caerdroia and constructing the "crucible world" of Bortresoye to conduct their experiments.
Eventually the cycle somehow caused the Divergence to wither and die but they were then absorbed by the creature known as Daqar Keep, who subsequently absorbed all their power and assumed their authority in the Divergent Universe. (AUDIO: The Next Life [+]Loading...["The Next Life (audio story)"])
